Answer:
A - they are vertical angles so they are equal to each other
b - dont really know this one
c - y=24 and 7 and 8 = 89
Step-by-step explanation:
You messed up because the angles given are not supplementary the angles given that are next to 7 and 8 are vertical then we can setup an equation which would be 5y-29=3y+19 and solve for y
step 1 add 29 to each side
5y=3y+48
step 2 subtract each side by 3y
2y=48
step 3 divide each side by 2
y=24
then we plug in 24 to one of the expressions
5(24)=120
120-19=101
but we are not done yet because it is asking for the value of angle 7 and 8
because angle 7 is supplementary to both all we have to do is subtract 101 from 180
180-101=89 so 7 and 8 =89
hope this helps :D
It is D because whenever you take away the zero the amount of both numbers would be the same and adding it to the second one would keep it the same. This is a known fact for all decimals the end in zero you can add as many and take away is money but it really only matters as to what the real numbers are they don’t include zero!
Answer:
y=1/5x+7
Step-by-step explanation:
just checked it on paper
The answer is 75% I used a calculator and Pen and Pencil and 75% is correct I even double checked with multiplication. If you want to check for yourself to find the % in the future divide the 300 by 400 and you'll get your decimal move the decimal to the right 2 times and you'll have your percent.
