Answer:
Step-by-step explanation:
x+y=10
x=10-y
x=10-5
x=5
3y= -3x+30
3(10-y)= -3(10-y)+30
30-3y= -30+3y+30
30+30-30=6y
30=6y
y=5
The surface area of a rectangular prism is:
A=2(LW+HW+LH) in this case:
A=2(24*13+24*29+13*29)
A=2(1385)
A=2770 mm^2
Answer:
20
Step-by-step explanation:
20 x 10 = 200
10% = 0.10
200 x 0.10 = 20
Answer:
17 degrees.
There is a right angle and we know that is 90 degrees. 73 degrees has a vertical angle which is 73 degrees. The opposite vertical angle adds up to another angle which gives you 90. Subtract 73 from 90 and you get 17.
