Solve x/3 = x+2/2
x=?
Answer:
x = -6
Step-by-step explanation:
∵ [tex]\frac{x}{3}=\frac{x+2}{2}[/tex]
* These are two equivalent fractions
we can solve by using cross-multiplication way
that means we multiply x by 2 and multiply (x + 2) by 3
∴ 2(x) = 3(x + 2)
* Take care about the multiplication of 3(x + 2) you must
multiply 3 by x and also multiply 3 by 2
∴ 2x = 3x + 6
* Now lets start to collect the like terms
∴ 2x - 3x = 6
∴ -x = 6
* Divide the both sides by -1
∴ x = -6
x = -3/2 (Or) x = -1.5
First apply the rule a/a = 1
2/2 = 1
x/3 = x +1
Multiply both sides by 3
(x/3 * 3) = (x * 3) + (1 * 3)
Simplify
x = 3x + 3
Subtract 3x from both sides
(x - 3x) = (3x + 3 - 3x)
Simplify
-2x = 3
Divide both sides by -2
(-2x / -2) = (3 / -2)
Simplify
x = -3/2

The ratio of the perimeters of two rectangles is 5 to 8 . the perimeter of the larger rectangle is 72 inches. What is the perimeter of the smallest triangle?
ANSWER
45 inches.
EXPLANATION
Let the perimeter of the smaller rectangle be x.
Then, the ratio of the perimeter of the smaller rectangle to the larger rectangle is
[tex]x:72=5:8[/tex]
We change the ratio to fraction to obtain,
[tex] \frac{x}{72} = \frac{5}{8} [/tex]
Multiply both sides by 72.
[tex]x = \frac{5}{8} \times 72[/tex]
[tex]x = 5 \times 9 = 45[/tex]
The perimeter of the smaller rectangle is 45 inches.
Answer:
45 inches
Step-by-step explanation:
The 72 inches is 8 parts of the ratio, hence
[tex]\frac{72}{8}[/tex] = 9 inches ← 1 part of the ratio
5 parts = 5 × 9 = 45 inches ← smaller perimeter

School A and B are competing in an academic contest. at the beginning of the final round, school A has 174 points and school B has 102 points, in the final round, correct answers earn 10 points and incorrect answers loose 6 points. school A hives the same number of correct and incorrect answers during the final round. school B gives no incorrect answers and the same number of correct answers as school A. the contest ends with te two schools tied. which equation models the scoring in the final round and outcome of the contest?
Answer:
School A gave 12 correct and 12 incorrect answers. School B gave 12 correct answers and the competition was tied.
Step-by-step explanation:
We are given the following information:
School A points = 174
School B points = 102
Every correct answer is awarded 10 points and every incorrect answer reduces 6 points.
Let x be the number of correct answer given by school A and thus x is the number of incorrect answer given by school A. The, school B also gives x number of correct answer.
Thus, the scored can be modeled with the following equations:
School A: [tex]174 + 10x - 6x = 174 + 4x[/tex]
School B: [tex]102 + 10x[/tex]
Since, both the schools tied, equating both the equations:
[tex]174 + 4x = 102 + 10x\\\Rightarrow 10x - 4x = 174 -102\\\Rightarrow 6x = 72\\\Rightarrow x= 12[/tex]
Thus, school A gave 12 correct and 12 incorrect answers. School B gave 12 correct answers and the competition was tied.

Prove: If a chord of a circle makes an angle of 30° with a diameter, prove that the distance from the center to the chord is one-fourth the length of the diameter.
Answer:
See explanation.
Step-by-step explanation:
Let BC be the diameter of the circle with center at point O, AB be the chord and ∠ABC=30°. OD is the distance from the center to the chord.
Consider triangle BDO. This triangle is special 30°-60°-90° right triangle. The leg OD is opposite to the angle of 30° and is half of the hypotenuse. The hypotenuse of the triangle BDO is BO. BO is the radius of the circle and is equal to half of the diameter AB. Thus,
[tex]OD=\dfrac{1}{2}BO=\dfrac{1}{2}\cdot \dfrac{1}{2}AB=\dfrac{1}{4}AB.[/tex]
What is the area of the trapezoid?
Answer:
Hi there!
I got the answer: 88 units^2
Step-by-step explanation:
to find the area you the formula: A=(a+b)/2 times height
"a" in this case is 17 and "b" is 27 because 5+5+17 is 27
height is 4
then you plug what you know into the equation
(17+27)/2 times 4 to get 88

b = 3/4a
a + b = 21
Answer:
(12, 9)
Step-by-step explanation:
Please enclose fractions inside parentheses in cases such as this one. You meant b = (3/4)a, not b = 3/(4a).
To solve this system, subst. (3/4)a for b in the 2nd equation, obtaining:
a + (3/4)a = 21.
Mult. all 3 terms by 4 to eliminate the fraction 3/4:
4a + 3a = 84
combining like terms: 7a = 84
Solving for a: a = 84/7 = 12.
If a = 12, b = (3/4)a = (3/4)(12) = 9
The solution is (12, 9)
Answer:
a=12
b=9

Jen slices a cone with a height of 10 centimeters and a radius of 4 centimeters using a plane that is perpendicular to the base and that passes through the vertex of the cone. What is the area of the cross-section in square centimeters?
A cone that is sliced through the vertex would make the shape of a triangle.
You are told the h eight is 10 cm and the radius is 4 cm.
The radius would be half the base, so the base would be 4 * 2 =8 cm.
The area of the triangle is found by multiplying the base by the height, then dividing by two.
Area = 8 x 10 = 80
80 / 2 = 40 square centimeters.

4(x + 5) > 10(x - 1)
Answer:
x < 5
Step-by-step explanation:
Solve the inequality by using the distributive property and inverse operations.
4(x + 5) > 10(x - 1)
4x + 20 > 10x - 10
20 > 10x - 4x - 10
20 > 6x - 10
20 + 10 > 6x
30 > 6x
5 > x
A child’s pool is in the shape of a rectangular prism with a height of 2 ft and a base that is 4 ft wide by 5 ft long. During the course of the summer, the child’s pool needed to be filled 3 times.
How many cubic feet of water were needed to fill the pool during the summer?
A. 40 ft³
B. 80 ft³
C. 120 ft³
D. 160 ft³
Answer:
C. 120 ft^3
Step-by-step explanation:
Area of rectangular prism is Length * Width * Height.
4 * 5 * 2 = 40
It was filled 3 times so multiply 40 by 30
40 * 30 = 120 ft^3

please help me find the surface area of the triangular prism ( number 3)
Check the picture below.
so the triangular prism is really 3 rectangles and two triangles stacked up to each other at the edges, so if we simply get the area of each figure individually and sum them up, that's the area of the prism.
let's notice, the triangles have a base of 2.4 and a height/altitude of 1.
[tex]\bf \stackrel{\textit{2 triangles's area}}{2\left[ \cfrac{1}{2}(2.4)(1) \right]}~~+~~\stackrel{\textit{right rectangle}}{(2\cdot 1.5)}~~+~~\stackrel{\textit{left rectangle}}{(2\cdot 1.7)}~~+~~\stackrel{\textit{bottom rectangle}}{(2\cdot 2.4)} \\\\\\ 2.4+3+3.4+4.8\implies 5.4+8.2\implies 13.6[/tex]

Select all of the terms that apply to the shape. pentagon hexagon heptagon octagon nonagon decagon regular polygon irregular polygon concave convex
Answer: Convex, heptagon, regular polygon
Answer:
Heptagon, Irregular Polygon, and Concave
Step-by-step explanation:
From The figure shown in the picture we can see that it has the following characteristics. These characteristics are the following
7 straight sides2- 90° angles2 angles less than 90°2 angles greater than 180°1 angles greater than 90° but less than 180°Based on these characteristics we can say that the figure meets all the requirements to be classified as Heptagon, Irregular Polygon, and Concave
Heptagon: are figures with 7 straight sides and 7 angles
Irregular Polygons: are polygons that can have sides of any length and each interior angle can be of different angles
Concave: are polygons that have one or more interior angles bigger than 180°
