X = 5
Step-by-step explanation:
78 = 12x+18
-18 -18
60 = 12x
5 = x
Answer:
40w + 16p ≤ 2000
Step-by-step explanation:
let 'w' = jugs of water
let 'p' = cases of paper
the area of shading will include negative values which you can ignore because those values do not apply to this problem
2(11p-4) to the second power
Answer:
there
Step-by-step explanation:
T = 4 + 2A
S = 5A - 8
T = S
Since T and S are equal, set them against each other
2A + 4 = 5A - 8
Subtract 2A from each side, and add 8 to each side
12 = 3A
Divide each side by 3
A = 4
If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.
Answer:
y = 2x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c ← is the partial equation
To find c substitute (- 2, 0 ) into the partial equation
0 = - 4 + c ⇒ c = 0 + 4 = 4
y = 2x + 4 ← equation of line
