To everyone dog, there are 2.5 cats
Because you take 2 and 5 and divide them both by 2
Answer:
Step-by-step explanation:
3(4a + 6b) = 3*4a + 3*6b = 12a + 18b
-2(7a + b) = -2*7a + (-2)*b = -14a - 2b
![\frac{5[3(4a+6b)-2(7a+b)-b]}{20}=\frac{5[12a+18b-14a-2b-b]}{20}\\\\ \frac{5[-2a+15b]}{20}=\frac{15b-2a}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5B3%284a%2B6b%29-2%287a%2Bb%29-b%5D%7D%7B20%7D%3D%5Cfrac%7B5%5B12a%2B18b-14a-2b-b%5D%7D%7B20%7D%5C%5C%5C%5C%20%5Cfrac%7B5%5B-2a%2B15b%5D%7D%7B20%7D%3D%5Cfrac%7B15b-2a%7D%7B4%7D)
x =1/4

Answer:
yes
Step-by-step explanation:
The value 8 is the solution to the equation because plugging 8 into the equation in place of the unknown variable x like 16(8) will equal 128.
Answer:
slope = - 
Step-by-step explanation:
Parallel lines have equal slopes thus the slope of a parallel line will be equal to the slope of PQ
To calculate slope m use the slope formula
m = 
with (x₁, y₁ ) = P(- 2, 4) and (x₂, y₂ ) = Q(6, - 2)
m =
=
= -
