Answer:
see below
Step-by-step explanation:
x - 2/5= 7
Add 2/5 to each side
x - 2/5 + 2/5 = 7+2/5
x = 7 2/5
or if
( x-2) /5 = 7
Multiply each side by 5
(x-2) /5 *5 = 7*5
x-2 = 35
Add 2 to each side
x-2+2 = 35+2
x = 37
(10x - 65) degrees is equal to (9x - 49) degrees, therefore you can set them into an equation.
(10x - 65) = (9x - 49)
By subtracting 9x in both sides,
(10x - 9x) - 65 = (9x -9x) - 49
x - 65 = -49
By adding 65 in both sides,
x - 65 + 65= -49 + 65
x = 16
Next, to find the value of z, it’s important to know that the straight line has 180 degrees. Then you would substitute the x value you found into one of your equation and subtract it from 180.
10 (16) - 65 = 160 - 65 = 95
Now you know that (10x - 65) degrees is equal to 95 degrees,
180 - 95 = z = 85
Answer: x = 16
z = 85
Answer:
Step-by-step explanation:
Plug each value of x into the equation and solve for the corresponding y value.
When x = -1, y = (-1)²-2(-1) = 3
When x = 0, y = 0² - 2(0) = 0
You can finish from here.
A=4
Just divide 5 on both sides :-)
A., because to find LCD, you must find the LCM of the three denominators. In this case, one of the denominators has the answer, which is 16, because 2, 8, and obviously 16 all go into 16.
You then have to also multiply the numerators by the same number that you are multiplying the denominators by. 2 x X = 16 -> X = 8, so you multiply 1 x 8 and get 8, so the first fraction is 8/16. 16 x X = 16 -> x = 1, 3 x 1 = 3, so the next one remains 3/16. 8 x X = 16 -> X = 2, 2 x 7 = 14, so the last one is 14/16.
