Find the values for x for which the expression 2x-3/(x+4)(x-2) is equal to 1/5
Answer:
1 and 7
Step-by-step explanation:
(x+4)(x-2) = x²+2x-8
set up proportion:
2x-3/ x²+2x-8 = 1/5
cross-multiply:
5(2x-3) = x²+2x-8
10x-15 = x²+2x-8
Combine Like Terms:
x²-8x+7
Factor:
(x-7)(x-1)
set each factor equal to zero and solve: x = 1, x = 7
Answer:
[tex] \frac{(2x - 3)}{(x + 4)(x - 2)} = \frac{1}{5} \\ \frac{2x - 3}{x {}^{2} - 2x + 4x - 8} = \frac{1}{5} \\ x {}^{2} - 2x + 4x - 8 = 5(2x - 3) \\ x {}^{2} + 2x - 8 = 10x - 15 \\ x {}^{2} + 2x - 10x = - 15 + 8 \\ x { }^{2} - 8x = - 7 \\ x {}^{2} - 8x + 7 = 0 \\ x {}^{2} - x - 7x + 7 = 0 \\ x(x - 1) + 7(x - 1) \\ x + 7 = 0 \\ x = - 7or \\ x - 1 = 0 \\ x = 1[/tex]
Step-by-step explanation:
x=7 or x=1
Find m RSU=103° what does UST=
Answer: UST = 77
Step-by-step explanation:
Angle RSU and angle UST together measure 180. (half of a circle) (or you can say they are a linear pair...either way they would sum to 180) 180-103 = 77

Ramon earns $1,725 each month and pays $53.70 on electricity. To the nearest tenth of a percent, what percent of Ramon's earnings are spent on electricity each month?
Answer:
Step-by-step explanation:
Remark
The formula you use is (Electricity / Total Income ) * 100
The ratio becomes 53.7/1725 * 100%
The ratio is 53.7/1725 * 100 = 0.03113 * 100
The % = 0.03113 * 100 = 3.113
To the closest tenth that is 3.1%
Luke walks 40 miles in 25 seconds and Maria walks 30 miles in 10 seconds who walks faster?
Answer:
Thank to Goalscore24 correcting me, its actually Maria walking faster
Because 40 divided by 25 is 1.6
and 30 divided by 10 is 3
So Maria runs 3 miles in 1 second, and Luke runs 1.6 miles in 1 second
So Maria is faster.

A home with an area of 2,200 square feet has 660 square feet of wood flooring. What percent of the home's flooring is wood
Answer:
30%
Step-by-step explanation:
Given data
Area of Home= 2,200 square feet
Area of wood flooring= 660 square feet
The percent of wood flooring in the house can be gotten as
=660/2200*100
=0.3*100
= 30%
Hence the wooden floor occupies 30%.

Answer:
[tex]64 - (a + b)^2[/tex]
Step-by-step explanation:
[tex]64 - a^2 - 2ab - b^2\\64 - (a^2 + 2ab + b^2)\\64 - (a + b)^2[/tex]
Answer:
Step-by-step explanation:
64 - a² - 2ab - b² = 64 -(a² + 2ab + b²)
= 8² - (a +b)² {x² - y² = (x + y)(x -y)
= (8 + a +b) (8 - (a +b))
=(8 +a + b)(8 - a - b)

The length of a side of a square is (6x + 6) km. Find the area of the square in terms of the variable x.
Answer:
36(x + 1)^2 = 0 or 36x^2 + 72x + 36
Step-by-step explanation:
s^2 = area of a square
(6x + 6) (6x + 6)
6x*6x = 36x^2
6x*6 = 36x
6*6x = 36x
6*6 = 36
36x^2 + 36x + 36x + 36
36x^2 + 72x + 36
36(x + 1)^2 = 0
Find the y-intercept of each line defined below and compare their values
Answer:
They are 8 units apart, and the y-intercept of line A is above the x-axis by 6 units, and line B is below the x-axis by 2 units
Step-by-step explanation:
Remember your y-intercept has an x value of zero, so line B has a y intercept of (0,-2)
now let's find b in the original equation so
y - 8 = -2x - 2 so y = -2x -2 + 8, so y = -2x + 6
So line A has a y-intercept of (0,6)
They are 8 units apart, and the y-intercept of line A is above the x-axis by 6 units, and line B is below the x-axis by 2 units
