She is right
It is equivalent to 7(6) + 14
Step-by-step explanation:
- Step 1: Solve 7(a + 2) when a = 6
⇒ 7 (6 + 2) = 7 × 8 = 56
- Step 2: Find its equivalent
7(6) + 14 = 42 + 14 = 56
Answer:
m is 3 since it's the slope and b is -2 since its the y-intercept
Step-by-step explanation:
the formula is y=mx+b so 3 is in the m spot and -2 is in the b spot.
Answer:
270
Step-by-step explanation:
360-90 =270 since the arc for xw is 90 then subtract the whole circle
Answer:
375 hamburgers
Step-by-step explanation:
The variables are the number of hamburgers and the number of cheeseburgers.
Let x represent the number of hamburgers sold on Monday and y represent the number of cheeseburgers sold on Monday.
Therefore:
x+y=816 (I)
The number of cheeseburgers is the number of hamburgers plus 66:
y=x+66 (II)
You have to solve the system of equation using a solving method, for example substitution:
Replacing (II) in (I) and solving for x:
x+x+66=816
2x+66=816
Subtracting 66 both sides:
2x=816-66
2x=750
Dividing both sides by 2:
x=375
Replacing the value of x in (II):
y=375+66
y=441
