Okay ! :) cool wait what this suppose to be a question?
It would be lines that are plane and line
Answer:
129
Step-by-step explanation:
for this one they gave us to angles and if you didnt know those angles are supplementary so they are going to add up to equal 180 so first things first is we want to find the value of x, to do that we do
180=x+19+4x+1
step 1 combine like terms
4x+x=5x
19+1=20
now we have
180=20+5x
step 2 subtract each side by 20
20-20 cancels out
180-20=160
now we have
160=5x
step 3 divide each side by 5
5/5 cancels out
160/5 = 32
x=32
now we want to plug in 32 for each expression to find which one is greater
(32)+19=51
4(32)=128
128+1=129
so the answer is 129
hope this helps :D
A ) equation would be X = Z / Y
B ) if X = 9 ------------> Y = 1/7
X = 21 ----------> Y = ?
21*1/7 = 21/7 , 21/7÷9 = 21*9/7 = 27
so Y equal 27
Answer: $0.6
Step-by-step explanation:
15cookies= $9
1 cookie = x
Cross multiply
15x= 9
Divide both sides by 15
x= 9/15= 3/5= $0.6
