For the linear equation, the value of x is 257/363.

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The linear equation is,

⇒ 8x + 32 = 15 (25x - 15) - 4x

Now, Solve the linear equation for value of x.

⇒ 8x + 32 = 15 (25x - 15) - 4x

⇒ 8x + 32 = 375x - 225 - 4x

⇒ 32 + 225 = 375x - 8x - 4x

⇒ 257 = 363x

⇒ x = 257 / 363

Answer:

the answer is x=185

Step-by-step explanation:

x+240=425

 -240  -240

x= 185

Answer:

B) x + 240 = 425

Step-by-step explanation:

Kyle and Tyler travelled 425 miles to the beach. This means that:

Kyle's distance + Tyler's distance = 425 miles

Kyle travelled 240 miles:

240 miles + Tyler's distance = 425 miles

We want to discover how far Tyler travelled:

240 miles + x = 425miles  or  x + 240 miles = 425 miles

This also means that:

425 miles - 240 miles = x

x = 185 miles

or

185 miles + 240 miles = 425 miles

x/9 = -6

Solve for X by multiplying both sides by 9:

x = -6 * 9

x = -54

Answer:

D . 58 miles

Step-by-step explanation:

In order to find the distance travelled (d) in each stage, we will use the following expression.

d = v × t

where,

v: speed

t: time

First stage

v = 70 mi/h

t = 45 min × (1 h / 60 min) = 0.75 h

d = v × t = 70 mi/h × 0.75 h = 53 mi

Second stage

v = 20 mi/h

t = 15 min × (1 h / 60 min) = 0.25 h

d = v × t = 20 mi/h × 0.25 h = 5.0 mi

The total distance tyraveled is 53 mi + 5.0 mi = 58 mi

Josie drove 52.5 miles for the first part of her trip and 5 miles for the second part, totaling 57.5 miles. After rounding, it is approximately 58 miles, so the answer is D.

To calculate the total distance Josie drove, we need to find the distance for each segment of her journey and then sum them up. For the first part of her trip, she drove for 45 minutes at a speed of 70 miles per hour. Since time needs to be in hours to use the formula distance = speed × time, we convert 45 minutes to hours by dividing by 60, giving us 0.75 hours. So, the distance for the first part is 70 miles/hour × 0.75 hours, which equals 52.5 miles.

For the second part of the trip, Josie drove for 15 minutes at 20 miles per hour. Converting 15 minutes to hours, we get 0.25 hours. Therefore, the distance for the second part is 20 miles/hour × 0.25 hours, giving us 5 miles. To find the total distance, we add the distances from both parts of the trip, resulting in 52.5 miles + 5 miles = 57.5 miles.

After rounding to the nearest mile, the total distance Josie drove was roughly 58 miles.

Therefore, the correct answer is D.

Answer:

$778.46 is the bi-weekly net pay

Step-by-step explanation:

Net pay  is the gross pay minus taxes

Net pay = gross pay - gross pay * tax rate

Simplifying this equation by factoring out gross pay

Net pay = gross pay (1- tax rate)

Substituting this in

Net pay = gross pay (1- tax rate)

We know the

hours worked = 23000

tax rate = .12

Net pay = 23000 (1- .12)

Net pay = 23000 (.88)

Net pay = 20240

But this is per year, and we want it bi weekly

There are 52 weeks in a year, divide by 2 (bi weekly)= 26

So divide 20240 by 26, so you get paid every 2 weeks.

$20240/26 = 778.46  (we round to the nearest cent)

Answer:

6%

Step-by-step explanation:

The percentage is the ratio 15/250 converted to a percent. That conversion can be accomplished by multiplying the ratio by 100%. (You can do this without a calculator.)

15/250 × 100% = (1500/250)% = 6%

6% of the students taking the state assessment exam forgot their calculator, as calculated by dividing the number of students who forgot the calculator (15) by the total number of students taking the exam (250) and then multiplying by 100%.

To calculate the percentage of students who forgot their calculator during the state assessment exam, we would use the formula for percentage, which is:

(Number of students who forgot their calculator / Total number of students taking the exam) × 100%

In this case, 15 students forgot their calculator out of a total of 250 students. By plugging these numbers into the formula, we get:

(15 / 250) × 100% = 6%

Therefore, 6% of the students taking the exam forgot their calculator.

let's recall that the sum of all interior angles in a triangle is 180°.

an equi-lateral, equal sides, triangle has all sides that are equal.

sides that are equal will yield an equal opposite angle.

so if all sides are equal, all angles are equal, for a sum of 180°, that's only possible with 60°, 60° and 60° angles, and all of them are acute, none obtuse.

Answer:

If c>0, then the solution is imaginary, which is not a real solution.

Step-by-step explanation:

ax^2 + c = 0, with a > 0

Subtract c from each side

ax^2 +c-c = 0-c

ax^2 = -c

Divide each side by a

ax^2/a = -c/a

x^2 = -c/a

Take the square root of each side

sqrt(x^2) = sqrt(-c/a)

AAAAAAAH

The only way to have real square roots is for -c/a to be positive.

We know that a>0, so -c >0

-c>0

Divide each side by -1, remembering to flip the inequality

c<0

If c<0  we have real solutions

If c=0  then x=0 which is a real solution

If c>0, then the solution is imaginary, which is not a real solution.

Step-by-step explanation:  

We have been give an expression [tex]700(1.005644)^{4x}[/tex] that shows the quarterly interest rate Letrice earns after x years.

We can find an equivalent expression with x isolated by using exponent properties.

Since power rule of exponents states that an exponent raised to another exponent can be simplified by multiplying the exponents

So using power rule of exponents we can write our expression as:

[tex]700((1.005644)^4)^x[/tex]

Now let us simplify our expression.    

[tex]700(1.0227678485832441)^x[/tex]

Upon rounding to 6 decimal places we will get,

[tex]700(1.022768)^x[/tex]

Therefore, the expression [tex]700(1.022768)^x[/tex] shows the x isolated in the exponent in an equivalent form.

Answer:

c) G= (4,0)

Step-by-step explanation:

Point A (-5,0)  and point E  is (7,4)

Point A (-5,0)  and point E  is (7,4)

A is on x axis so F is also on x axis. So F is (7,0)

AE is divided into 4 equal parts

First we find the distance between A  and F. Then divide it by 4

A is (-5,0)  and F is (7,0)

Distance = 7 -(-5) = 12

Now divide it by 4  so 12/ 4= 3

We subtract 3 from point F(7,0) to get point G

G= (7-3,0)

G= (4,0)

BD = 9 cm

Step-by-step explanation:

In a 30°-60°-90° triangle, the ratio of side lengths is 1 : √3 : 2. That is, the longest side (hypotenuse) is twice the length of the shortest side.

All of the triangles in your geometry are 30°-60°-90° triangles. AC is the hypotenuse of ΔACD, and the short side of ΔABC.

The short side AD of ΔACD will be half the length of AC, so 3 cm. The hypotenuse AB of ΔABC will be twice the length of AC, so 12 cm. Segment BD is the difference of the lengths AB and AD, so is ...

... BD = AB -AD

Answer:

1/7th

Step-by-step explanation:

To find the perpendicular slope find the negative reciprocal

e.i. 1/3 would be -3/1 or -3

The slope of the line perpendicular to y = -7x - 12 is 1/7.

The slope of a line perpendicular to another line is the negative reciprocal of the slope of the original line.

The given line has a slope of -7, so the slope of the line perpendicular to it would be the negative reciprocal of -7, which is 1/7.

Therefore, the slope of the line that is perpendicular to the line y = -7x - 12 is 1/7.

Answer:

∠1 = ∠2 = ∠3 = ∠4 = 28°

Step-by-step explanation:

A rhombus is a parallelogram with congruent sides. As with any parallelogram, the sum of adjacent interior angles is 180°. The figure is symmetrical, so either diagonal is also an angle bisector.

By any of various rules related to parallel lines and/or angle bisectors and/or isosceles trianges, all of the numbered angles are congruent (= α). Each of them is the complement of half the angle measure shown.

... α = (1/2)(180° -124°) = 90° -62° = 28°

The measure of the numbered angles in each rhombus is [tex]28^\circ[/tex] and this can be determined by using the properties of a rhombus.

Given :

A rhombus ABCD whose [tex]\rm \angle C = 124^\circ[/tex].

A rhombus is a quadrilateral whose all the sides are equal, opposite angles are equal, and opposite sides are parallel.

Line BD is the angle bisector and triangle BCD is the isosceles triangle and therefore, all the numbered angles 1, 2, 3, and 4 are equal.

[tex]\angle 1 = \angle 2 = \angle 3 = \angle 4[/tex]

[tex]\angle 1 = \angle 2 = \angle 3 = \angle 4 = \dfrac{1}{2}(180^\circ-124^\circ)[/tex]

[tex]\angle 1 = \angle 2 = \angle 3 = \angle 4 = \dfrac{1}{2}(56^\circ)[/tex]

[tex]\angle 1 = \angle 2 = \angle 3 = \angle 4 = (28^\circ)[/tex]
