Answer:
exact form: 13/5
Decimal form: 2.6
x= 2 3/5
Step-by-step explanation:
3x+4x-7=8-3x+11
7x-7=8-3+11
7x-19-3x
7x-7 + 7 =-3x+19+7
7x=-3+26
10x=26
x= 13/5
Answer:
the second one(20)
Step-by-step explanation:
If you pretend 20 is x, you solve the equation by pluging in x (20) into the equation and it gives you 70, 70 is what the big part is and 70+20 is 90, which is the size of a 90degree side.
4(20)-10
80-10
70
70+20=90
Answer:
Perimeter = 16x + 16
Area = 40x + 15
Step-by-step explanation:
Perimeter = the sum of all the side lengths
Perimeter = 2(8x+3) + 2(5) = 16x + 6 + 10 = 16x + 16
Area = product of base times height
Area = (8x+3)*5 = 40x + 15
Answer:
896 inch^3
STAY SAFE, GOD BLESS YOU :)
Step-by-step explanation:
V = l x w x h
= 19 x 2 x 7
= 266 inch^3
= 6 x 15 x 7
= 630 inch^3
Add them both
= 630 + 266
= 896 inch^3
Answer:
