1. sum of a number plus 6 is 7 times the number:
n+6 = 7n
2. qoutent of a number and 5 is 8
n/5 =8
n = 5*8
n = 40
3. distance = speed times time
so d = 55t
Answer:
Step-by-step explanation:
a. 4cm * 9cm * 2cm = 72 cm^3
b. 5m * 4m * 9m = 180 m^3
c. 10dm * 36 dm^2 (because the square could also be represented as 6cm * 6cm) =360 dm^3
d. (56mm)^3 = 175616 mm^3
e. 10 m * 1 m^2 (because of the square) = 10m^3
Answer:
Step-by-step explanation:
180 - 152 = 28
2x + 28 = 180
2x = 152
x = 76
Answer:
22 in
Step-by-step explanation:
<u>circumference of a circle = 2 π r</u>
where radius (r) = 7/2 in. = 3.5 in
C = 2 π (3.5)
= 22 in
