1) Circumference = π*diameter
= 3.14*10 = 31.4 inches
2) 130% of 74 = 1.3 x 74
= 96.2
C + t = 75......c = 75 - t
6c + 3t = 312
6(75 - t) + 3t = 312
450 - 6t + 3t = 312
-6t + 3t = 312 - 450
-3t = - 138
t = -138/-3
t = 46 <=== 46 cups of tea were sold
c = 75 - t
c = 75 - 46
c = 29 <=== 29 cups of coffee
No. It’s A. There are 8 km per 5 miles. How many Miles are in 120 km? In other words, 120 km/ x miles. Find x. You cross multiply giving you 8x=600. Divide by 8 on each side. Giving you x=75. So your answer is A
Three more than the variable n.
Let’s divide this fully into 5ths to make it easier.
7 and 4/5 also equals 39/5.
39 is what we call a prime number so we can’t factor 109200 with it, so all we have left that we can do is divide.
109200/39=$2800
$2800 is 1/5 of the total, so just multiply that by 5 and you have your answer!
2800x5=$14,000.
