Answer:
17/5
Step-by-step explanation:
Multiply 3 with the denominator 5.
3 * 5 = 15
Then add the product to the numerator
15 + 2 = 17
Keep the 5 as the denominator.
So the final answer is 17/5
Y=t+12 this is one the answers
20+20+15+15=70
20times 15=300
The dimensions are 20 ft, 15 ft
Answer:
65 degrees
Step-by-step explanation:
First, solve for the unknown angle( not the y's).
the angle 130 is supplementary to that angle so we will use an equation to solve it. (supplementary means it adds up to 180 degrees)
x+130=180
-130 -130
x = 50 so, 50 is the measure of the interior angle
Now we have to use another equation to solve for y:
50+2y=180
-50 -50
2y = 130
/2 /2
y = 65
Thus, y is 65
J=2l
j+l=240
sub 2l for j
2l+l=240
3l=240
divide both sides by 3
l=80
sub
j=2l
j=2(80)
j=160
