Answer:
I’m sorry I don’t know the answer I wish I could help
Step-by-step explanation:
We can model this situation.
Raina received a total of 83 calls
First evening she received 7 more than the third so let x = third and since we know she received 7 more we know to add 7 to the third so (x + 7)
Second evening she received 2 times as many as the third so 2 time third, which x is the third so (2 times x) or we could say 2x
Third evening = x
So now lets solve for x and then we can find how many she received each evening.
Our Model: (x + 7) + 2x + x = 83
(x + 7) + 2x + x = 83
x + 7 + 2x + x = 83
x + 2x + x + 7 = 83
4x + 7 = 83
4x + 7 - 7 = 83 -7
4x = 76
4x / 4 = 76 / 4
x = 19
First evening:
19 + 7 = 26 calls
Second evening
2 times 19 = 38
Third evening
19
Check our answer:
26 + 38 + 19 = 83
Answer:
What graph?
Step-by-step explanation:
Answer:
the sum of 1.25+(0.75)=2.00
Set it up as an equation. "A number" is x.
2x-2=x+64
Move all of the x terms to one side by subtracting x from both sides, then add 2 to both sides to isolate x.
X=66
The number is 66
