They are simple linear equations with one unknown, lets tackle them, one step at the time solving for the unknown:
4x - 2(x - 5) = x + 13
4x - 2x + 10 = x + 13
2x + 10 = x + 13
2x - x = 13 - 10
x = 3
that is the solution.
3(6 - x) - 4 = 5x + 2(7x + 3)
18 - 3x - 4 = 5x + 14x + 6
14 - 3x = 19x + 6
14 - 6 = 19x + 3x
8 = 22x
x = 8/22 = 4/11
Answer: $13,846.02
Step-by-step explanation:
The car cost $29,750 when it was first bought.
It will then depreciate at a rate of 12% per year. This means that the value of the car reduces by 12% per year.
To find the value of the car in the 6th year, you can use the compound interest formula:
= Value of car * ( 1 - rate) ^ no. of years
= 29,750 * ( 1 - 12%)⁶
= 13,816.021581824
= $13,846.02
Do you have 1 7/8 divided by one half. With dividing you multiply by the reciprocal of 1/2 which is 2/1. Before you do that change 1 7/8 into a mixed number which is 15/8. 15 x 2= 30, 8 x 1=8. New fraction is 30/8. Now as a mixed number it is 3 6/8 which simplifies to 3 3/4. So your answer is D
Answer:
A
Step-by-step explanation:
A triangle has 180 degrees.
So, 10 + 145 + x = 180
x = 25
This means that the angles in the triangle are:
10, 145, and 25
Using this information, only A has the same values so it is the answer
