Answer: 2
Step-by-step explanation: 1+1=2
To let the variable alone you can follow these steps: 1) subtract 228 from both sides 2) divide both sides by 4. This is the solution: 1) 4y + 228 - 228 = 352 - 228 => 2) 4y = 124 => 3) (4y)/4 = 124/4 => 4) y = 31. Then, <span>the answer is the option A. y = 31. </span>
Answer:
-30
Step-by-step explanation:
f(x) = 3 so f(-8) = 3;
g(x) = 5x + 7, so g(-8) = 5(-8) + 7 = -33
Then (f + g)(-8) = 3 - 33 = -30
This is the sum of two functions both evaluated at x = -8.
Answer:
11 years old
Step-by-step explanation:
Maggie's age is x
Maggie's brother = 4x - 7
The sum is 48
x + 4x - 7 = 48
5x - 7 = 48
5x = 55
x = 11
It looks like angle FPG = twice angle FHG - which makes sense looking at it now, but I came up with the answer another way - see attached
