Answer:
<em>start with y</em>
y
<em>add 7</em>
y+7
<em>multiply by 3</em>
3(y+7)
<em>subtract 6</em>
3(y+7)-6
<u>therefore the answer is:</u>
3y + 21 - 6
=
3y + 15 or 3(y+5)
Answer:
n =22
Step-by-step explanation:
12-5=7
15-5=10
20-5=15
n-5=17
collect like terms
n=17+5
n=22
Set it up 180=(7x+10)+ z because angle b is on the flat line and then solve for x (180-10, then 170/7) and you’ll get the value of x and from there you can put it in all
