Answer:
a =9
b= 28
Step-by-step explanation:
The parts of the ratio must be equal
5:7:a = 20:b:36
How do we get from 5 to 20
We multiply by 4
So multiply the first by 4
5*4:7*4:a*4 = 20:b:36
Ratio 1
5*4 =20 true
Ratio 2
7*4 =b
28 = b
Ratio 3
4a = 36
Divide by 4
4a/4 = 36/4
a = 9
P=21..........................

Slope is equal to the change in y over the change in x,<span> or 'rise over run'.
</span><span>m=change in y/change in x
</span>The change in x is equal to the difference in x-coordinates (also called run), and the change in y is equal to the difference in y-coordinates (also called rise<span>).
</span><span>m=y^2−y^1/x^2−x^1
</span>Substitute in the values of x and y into the equation to find the slope<span>.
</span><span>m= 1/2 −(− 3/2 )/ 3/5 −( 2/10 )
</span><span>Simplify.
</span><span>m=5
The slope is 5</span>
Answer:
A, B, and C
Step-by-step explanation:
The answer for 15.2+w=19.75+4.2 is <u>w=8.75</u>
3w=22.25+4 is <u>w=8.75</u>
The next equation is w= -8.75
The last equation is <u>w= 8.75</u>
