Answer:
$1,080
Step-by-step explanation:
To solve, we can make a proportion
14 lessons are $210 and 72 lessons are $x
14/210=72/x
Cross multiply
14*x=210*72
14x=15120
To solve for x, we need to get x by itself. Since x is being multiplied by 14, divide both sides by 14.
14x/14=15120/14
x=1080
So, 72 lessons will cost $1,080
Pythagoras theorem I guess
C. Because it only gives the measure of angles on line p and not line q
Y=2/3x-3. Follow the formula y=Mx+b. M is the slope, and b is the y intercept.
Answer:
x=165
Step-by-step explanation:
Multiply both sides by 15
15(x/15)=11*15
x=165
