Answer:
n = 21
Step-by-step explanation:
5(n-7)=2(n+14)
Distribute
5n -35 = 2n+28
Subtract 2n from each side
5n-2n -35 = 2n-2n +28
3n-35 =28
Add 35 to each side
3n-35+35 = 28+35
3n = 63
Divide by 3
3n/3 = 63/3
n =21
Answer:
y=x*7
Step-by-step explanation:
63=9*7
28=4*7
14=2*7
77=11*7
Answer:
the answer is c
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
QY = 5x
YZ = 18
QZ = 53
Thus:
QY + YZ = QZ (segment addition postulate)
5x + 18 = 53
5x = 53 - 18 (subtraction property of equality)
5x = 35
Divide both sides by 5
x = 7
1.086 rounded to the nearest whole number would remain as one.
This is due to the fact that the tenths place does not have any number, and due to this the whole number would remain one.
If the number were to change, it would look as the following:
1.5 rounded to the nearest whole number 2.
