X=-2
Subtract the 2x from both sides and get 7x-19=-5 and then add 19 to both sides and you get 7x=-14 divide by 7 and x=-2
Answer:
x =150 men
Step-by-step explanation:
Think of the total as workdays
125men* 120days = 15000 workdays
We still need 15000 workdays
100 days * x = 15000workdays
Divide by 100
x = 15000/ 100
x =150 men
Answer:
0.05
Step-by-step explanation:
this is because the total probability always adds up to 1
Answer: x = 101.75
Step-by-step explanation:
Hi, to answer this question we have to solve the equation give, by isolating x:
8x-4 = 810
The first step is to Add 4 on both sides:
8x-4+4 = 810+4
8x = 814
Then we have to divide both sides by 8:
8x/8 = 814/8
Finally, the solution is:
x = 101.75

Answer:
a. 18 cm
Step-by-step explanation:
We are given that a circle has an area of 324π cm2. We are required to determine its radius. The formula for the area of a circle with radius r units is;

We plug in the area given and solve for r;

The radius of the circle is 18 cm
