Answer:
150
Step-by-step explanation:
The overall answer should equal 360. 90+90+30=210. That leaves us with x. Try subtracting 360-210=x. :) Hope this helps!
Answer:
It is c = kt.
Step-by-step explanation:
This is direct variation . As the time increases the number of cranes increases.
The equation is c = kt where k is the constant of variation. In this case it will be a positive value because c is increasing with time.
If they make 20 cranes in 10 minutes then we can find the value of k by plugging in these values;
20 = k * 10
g = 20/10
k = 2.
So they make 2 cranes per minute.
Answer:
= 3.1
Step-by-step explanation:
4.7(5) - 6.8 (3)
23.5 - 20.4
= 3.1
Answer:
X = -3333/100000
Step-by-step explanation:
Given that a rational number is such that when you multiply it by 5/2 and add 2/3 to the product you get 7/12, to determine what is the number the following calculation must be performed:
X x 5/2 + 2/3 = 7/12
2.5X + 0.666 = 0.583333
2.5X = 0.58333 - 0.6666
X = -0.08333 / 2.5
X = -0.033333
X = -3333/100000.
