Answer: Sabrina read 65 pages on the second and third days
Step-by-step explanation:
45 + 2x = 175
45 - 45 + 2x = 175 -45
2x = 130
2x/2 = 130/2
x = 65
CHECK: 45 + 65 +65 = 175
Answer:
No solution.
Step-by-step explanation:
The equation 2x + 8 = 2(x + 5) has no solution as we see if we simplify it:
2x + 8 = 2x + 10
2x - 2x = 10 -8
0 = 2 which is absurd.
Answer:216
Step-by-step explanation:
We let x to represent the number of other nuts
Peanut : other
5 : 3
360 : X
Then we cross multiply
5 × x = 360 × 3
5X = 1080
Divide bothside by 5
5X/5 = 1080/5
X = 216
Therefore the number of other nuts in the can is 216.
Answer:
3200/560000983663562666663672
-(7x + 4)- 2x + 2 = 52
Distribute the negative sign:
-7x -4 - 2x + 2 = 52
Combine like terms:
-9x - 2 = 52
Add 2 to both sides:
-9x = 54
Divide by -9:
x = -6
Answer: x = -6
