Q1.
[tex]x + 20 = - 32[/tex]
Add -20 to both sides of the equation.
[tex]x + 20 - 20 = - 32 - 20[/tex]
Simplify
[tex]x = - 52[/tex]
Q2.
[tex]w + 10 = 25[/tex]
Add -10 to both sides of the equation.
[tex]w + 10 - 10 = 25 - 10[/tex]
[tex]w = 15[/tex]
Q3.
[tex]7.2 + b = 12[/tex]
Add -7.2 to both sides of the equation.
[tex] - 7.2 + 7.2 + b = 12 - 7.2[/tex]
[tex]b = 4.8[/tex]
Q4.
[tex]5.3 + s = 15[/tex]
Add -5.3 to both sides to get,
[tex]s + 5.3 - 5.3 = 15 - 5.3[/tex]
Simplify:
[tex]s = 9.7[/tex]
Q5.
[tex]p + ( - 25) = - 10[/tex]
Add 25 to both sides,
[tex]p - 25 + 25 = - 10 + 25[/tex]
[tex]p = 15[/tex]
Q6.
[tex]m + - 1.6 = -4.8[/tex]

A rectangular prism has a volume of 189cm^3. The height of the prism is 3cm. What are the dimensions of the base
Answer:
l = 9 cm
b = 7 cm
h = 3 cm
Step-by-step explanation:
Formula:-
Volume of cuboid = lbh
l - Length of cuboid
b - breadth of cuboid
h - Height of cuboid
To find the dimensions of prism
Here prism is like a cuboid.
Volume of prism = 189 cm^3
Height h = 3 cm
Volume = lbg
189 = l * b* 3
l * b = 189/3 = 63 = 9 * 7
Therefore l and b may be 9 and 7

What is the quotient?
Answer: FIRST OPTION
Step-by-step explanation:
According the quotient of powers property, when you have the division of two powers with the same base, then you must subtract the exponents.
Therefore, keeping the property above on mind, you have that the quotient is the shown below:
[tex]\frac{(-7)^2}{(-7)^{-1}}=(-7)^{(2-(-1))}=(-7)^{(2+1)}=(-7)^3=-343[/tex]
use a absolute value to write a rule for determining the distance between two points on a coordinate plane that have the same x-coordinate
Answer:
For two points (x,a) and (x,b), the distance would be |a-b| or |b-a| both would be the same.
Step-by-step explanation:
What is the rule without an absolute value? basically we are looking for the difference (which is the answer to a subtraction problem) between the two.
Say the two points are (x,a) and (x,b) So they have the same x value but different y values. Now, when you want to take the difference you usually want to subtract the smaller number from the larger, but hat happens if you don't? So instead subtract the larger number from the smaller number? I'm gonna show a few examples.
7-5 = 2
5 - 7 = -2
7 - 3 = 4
3 - 7 = -4
As you can see, no matter which order you subtract you will always get the same number, just either positive of negative. We are going to use that. Basically, we can have the two in either order, as long as we have them inside of an absolute value, we will always get the same answer.
so, for our two y values, a and b, it doesn't matter which is larger |a-b| = |b-a| and this is the distance.
The distance between two points that have the same x-coordinate on a coordinate plane can be calculated by taking the absolute difference of their y-coordinates. This calculation will always yield a positive value, reflecting the fact that distance is a scalar quantity.
Explanation:The distance between two points with the same x-coordinate on a coordinate plane (i.e., two points on a vertical line) can be determined using absolute value. If these points have y-coordinates of y1 and y2, the distance between them (d) is the absolute difference of their y-coordinates. Mathematically, this is expressed as:
d = |y2 - y1|
Here, the symbol '|' surrounding the difference represents the absolute value, which makes any negative result positive. For example, if we have points A(3, 4) and B(3, 1), using our rule, the distance between these points would be |1 - 4| = |-3| = 3 units.
This absolute value method ensures that the distance is always a positive number, regardless of whether y2 is bigger than y1 or not. This essentially reflects the basic principle of distance being a scalar (having only magnitude but not direction).

One bag of topsoil covers 20 square meters.
How many bags of topsoil does Betsy need to cover her flower bed?
A 2 bags
B 3 bags
C 4 bags
D 5 bags
Answer:
Option B. 3 bags
Step-by-step explanation:
step 1
Find the area of the flower bed
The area of the flower bed is the area of a triangle
A=(1/2)bh=(1/2)(20)(6)=60 m^2
step 2
Divide the area by 20 square meters to find the number of bags of topsoil
(60)/(20)=3 bags

In a right triangle that has one acute angle of 18 degrees, cos 18 degrees is congruent to ?
Answer:
cos(18°)=sin(72°)
Step-by-step explanation:
we know that
In a right triangle
cos(A)=sin(B)
If A and B are complementary angles
so
A+B=90°
In this problem
A=18°
B=90-18=72°
therefore
cos(18°)=sin(72°)
Tony’s credit card statement says that he must pay a minimum payment of 15% or $20 whichever is greater. How much will he pay if his new balance is $138.90
Answer: $20.84
Step-by-step explanation: In order to calculate Tony’s minimum payment you need to calculate how much 15% is of his balance.
138.90 x .15 = $20.84, which is 15% of his balance.
The minimum payment is the greater of 15% or $20, so his minimum payment will be $20.84.
The answer is $188.90. If I am wrong, please correct me.

base of parallelogram = 4*4 = 16
Since there are two of them, the area = 2 * 16 = 32
left and right faces
I think you have to assume this is a rectangle. We do not know the height for a parallelogram.
Area = l*w
Area = 4 * 2.5
Area = 10 in^2
But there are two of them.
Area = 2* 10 = 20 in^2
Front and back faces
The area is the area of a parallelogram
Area = b * h
Area = 2 * 4
Area = 8 in^2
But there are 2 of them
The area for 2 is 8*2 = 16 in^2
Total Area
Total Area = 16 + 20 + 32
Total Area = 68 in^2

Is F(x)= X^2(X^2+9)(X^3+2X) even or odd
Answer:
The function is odd.
Step-by-step explanation:
A function is even if the graph of the function is symmetric with respect to the y-axis. A function is odd if the graph of the function is symmetric with respect to the origin. To find if the function is even or odd, we're going to graph the function using DESMOS.
As you can see in the attached picture, the function is symmetric with respect to the origin. Therefore, the function is odd.

Two cyclists, Alan and Brian, are racing around oval track of length 450m on the same direction simultaneously from the same point. Alan races around the track in 45 seconds before Brian does and overtakes him every 9 minutes. What are their rates, in meters per minute?
Answer:
Alan: 200 m/min
Brian: 150 m/min
Step-by-step explanation:
Given : Two cyclists, Alan and Brian, are racing around oval track of length 450m on the same direction simultaneously from the same point. Alan races around the track in 45 seconds before Brian does and overtakes him every 9 minutes.
To find : What are their rates, in meters per minute?
Solution :
Let n represent the number of laps that Alan completes in 9 minutes.
Then n-1 is the number of laps Brian completes.
45 seconds = 3/4 minutes.
The difference in their lap times in minutes per lap is
[tex]\frac{9}{(n -1)}-\frac{9}{n} =\frac{3}{4}[/tex]
Solving the equation we get,
[tex]\frac{9n-9n+9}{n(n -1)} =\frac{3}{4}[/tex]
[tex]9\times 4=3\times n(n -1)[/tex]
[tex]36=3\times n(n -1)[/tex]
[tex]n^2-n-12=0[/tex]
[tex]n^2-4n+3n-12=0[/tex]
[tex]n(n-4)+3(n-4)=0[/tex]
[tex](n-4)(n+3)=0[/tex]
[tex]n=4,-3[/tex]
Neglecting n=-3
So, n=4
Then Alan's speed in m/min is
[tex]S=\frac{D}{T}[/tex]
[tex]S_a=\frac{4\times 450}{9}[/tex]
[tex]S_a=200 m/min[/tex]
Brian completes 3 laps in that 9-minute time, so his rate is
[tex]S_b=\frac{3\times 450}{9}[/tex]
[tex]S_b=150 m/min[/tex]
Therefore, Alan: 200 m/min
Brian: 150 m/min
