Answer:
x= -15/2 y=-33/2
Step-by-step explanation:
i dont know how you want to solve it but if it is "system of equations" then first solve for the first variable in on e of the equations, then substitute the result into the other equation.
Answer:
B
Step-by-step explanation:
![m\angle ABZ+m\angle ZBC=m\angle ABC \\ \\ 12x+55=16x+15 \\ \\ 4x=40 \\ \\ x=10 \\ \\ \therefore m\angle ABZ=120^{\circ}](https://tex.z-dn.net/?f=m%5Cangle%20ABZ%2Bm%5Cangle%20ZBC%3Dm%5Cangle%20ABC%20%5C%5C%20%5C%5C%2012x%2B55%3D16x%2B15%20%5C%5C%20%5C%5C%204x%3D40%20%5C%5C%20%5C%5C%20x%3D10%20%5C%5C%20%5C%5C%20%5Ctherefore%20m%5Cangle%20ABZ%3D120%5E%7B%5Ccirc%7D)
Answer:
Yes because after solving the equation, x does indeed equal 14.
Step-by-step explanation:
-5 + 2x = 23
2x = 23 + 5
2x = 28
x = 14
You convert a decimal to a fraction by putting the digits to the right of the decimal point over "1" followed by the same number of zeros. (Most folks learn this in 3rd or 4th grade.)
0.66 = 66/100 . . . . . 2 decimals, so the denominator is 100
Then you reduce the fraction by canceling common factors. It helps to know your times tables and divisibility rules. (Or you can have your calculator do it.)
0.66 = 66/100 = 33/50
1.00 = 100/100 = 1
Answer:
P = A + B + C
Step-by-step explanation:
Essentially, just add the length of each side. The sum is the perimeter.
