10.) you would take 5 and plug it in for b, then the problem would be 4 x 5 - 1
Following the rules of pemdas
(parentheses, exponents, multiply, divide, add, subtract)
you would do
4 x 5 = 20
20-1 = 19
11.) you would plug in 6 for m, therefore the problem will then be 5 + 2 x 6 squared
To solve it you would do 6 squared first and get 36
Then 2 x 36 is 72
5+72 is 77 which is the final answer
12.) following the other problems above you would plug in the number for the variable
In this problem you would plug in 1 for y squared so the problem would be
3 x 1 squared - 2
You would do 1 squared first and get 1
Then you would do 3 x 1 and get 3
And 3 - 2 is 1
13.) plug in 3 for a so you would get the problem
5 x 2 x 3 cubed
You would do 3 cubed first and get 27
5 x 2 is 10
10 x 27 is 270
14.) here you would plug in 5 for both c's so the problem would be
4 x 5 squared - 2 x 5
You would square the 5 first and get 25
4 x 25 is 100,
2 x 5 is 10
100-10 is 90
16.) you still would plug in so when you do you should get
40 - (32/4)
First you would do 32 and divide it by 4 and get 8
Then 40-8 is 32
I'll include all the word here at the bottom without words to maybe help you better

13.) 5x2a cubed ; a = 3
5 x 2 x 3 cubed
5 x 2 x 27
10 x 27
270
14.) 4c squared - 2c ; c = 5
4 x 5 squared - 2 x 5
4 x 25 - 2 x 5
100 - 2 x 5
100 - 10
90
16.) 40 - (32/r) ; r = 4
40 - (32/4)
40 - 8
32
Answer:
-5|0|-7
-6|-4|-2
-1|-8|-3
I'm guessing it is addition
Hope this helps
Step-by-step explanation:
"of" means multiply
So 65% * 40
65% is the same as 0.65 (% means divide by 100).
0.65 * 40 = 26

Step-by-step explanation:
Given
equation of circle ![x^2+y^2=1](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3D1)
Equation of tangent passing through (1,1)
Slope of tangent is given by differentiating equation of circle

at ![(x,y)=(1,1)](https://tex.z-dn.net/?f=%28x%2Cy%29%3D%281%2C1%29)
![\frac{\mathrm{d} y}{\mathrm{d} x}=\frac{-1}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cmathrm%7Bd%7D%20y%7D%7B%5Cmathrm%7Bd%7D%20x%7D%3D%5Cfrac%7B-1%7D%7B1%7D)
Equation of line with slope
![m=\frac{y-y_0}{x-x_0}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7By-y_0%7D%7Bx-x_0%7D)
![-1=\frac{y-1}{x-1}](https://tex.z-dn.net/?f=-1%3D%5Cfrac%7By-1%7D%7Bx-1%7D)
We will simplify the inequality to:
x > -3
Then we conclude that the correct option is d.
<h3>
</h3><h3>
Which number line shows the solution of the inequality?</h3>
Here we have the inequality:
-5x + 20 < 35
Solving it for x, we get:
-5x < 35 - 20
-5x < 15
x > 15/(-5)
x > -3
(the direction of the symbol changes because we divided by a negative number).
Then the number line must have an open circle at x = -3 (because it is not a solution) and an arrow that extends to the right side (the values larger than -3).
From that, we conclude that the correct option is D.
