Answer:
Step-by-step explanation:
a) 15 + 6x = 81
6x = 81 - 15
6x = 66
x = 11
b) 40 + 55h = 190
55h = 190 - 40
55h = 150
h = 2.7
c) (p + 7)/12 = 3
p + 7 = 36
p = 36 - 7
p = 29
Answer:
The proportion <u>1 L : 0.26 gal = x L : 12500 gal</u>.
Step-by-step explanation:
Given:
A fountain holds 12,500 gallons of water.
1 L = 0.26 gal
Now, to get the proportion to solve for the number of litres.


<em>On solving :</em>

Therefore, the proportion <u>1 L : 0.26 gal = x L : 12500 gal</u>.
Answer:
x = 12
Step-by-step explanation:
they are virtical menaing they are the same value
6x + 7 = 8x - 17
6x + 24 = 8x
24 = 2x
12 = x
Answer:
E. 5
Step-by-step explanation:
Let's rewrite the equation in the form of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).
2x + y = 5
y = -2x+5
M, the slope, is -2
<u>5, b, is the y-intercept</u>
