After x weeks:
Jules will have: 1,200 + 40 x.
Kelsey will have: 400 + 50 x.
If we want to know in how many weeks will they have the same amount of money, we will make an equation:
400 + 50 x = 1,200 + 40 x
50 x - 40 x = 1,200 - 400
10 x = 800
x = 800 : 10
x = 80
Answer: In 80 weeks they will have the same amount of money.
The answer should be 25.12
Step-by-step explanation:
-2j < -14
Divide both sides by -2:
j > 7. (D)
Answer:
a graph can be divided into 4 quadrants.
a zero abscissa, means the point lies on the origin.
a negative ordinate means the point lies on the y axis in the third and fourth quadrants.
Answer:
the equation representing total amount of blood donated is
.
Step-by-step explanation:
Total number of volunteers = 32
number of volunteers couldn't donate blood =
.
So Number of volunteers who donated blood can be calculated by subtracting number of volunteers couldn't donate blood from Total number of volunteers.
Framing in equation form we get;
So, the number of remaining volunteers who donated blood =
.
Each of these volunteers donated blood = 470 ml
Now Total Amount of Blood donated is equal to Amount each of these volunteers donated blood times the number of volunteers who donated blood.
Framing in the equation form we get;
total amount of blood donated milliliters = 
Hence the equation representing total amount of blood donated is
.
