Answer:
105
Step-by-step explanation:
15x=7x+6+7x+1
15x=14x+7
x=7
15(7)=105
Answer:
Step-by-step explanation:
Volume= length × width × height.... Volume= 20 1/2 × 12 × 10 1/4..... Volume= 2521 1/2 cubic inches or 2521.5 cubic inches
Answer:
39
Step-by-step explanation:
Simplify using bodmas
3×(8+5)
3×13 = 39
By definition, the area is given by:
A = w * l
Where,
w: width
l: length
We have two expressions for the length:
L = 14\\L = 5 + 3c
Since the length is the same, we equate both expressions:
5 + 3c = 14
From here, we clear the value of c:
3c = 14 - 5\\3c = 9
c = \frac{9}{3}\\c = 3
Then, we have that the width is given by:
W = 6c-8
Substituting the value of c we have:
W = 6 (3) -8\\W = 18-8\\W = 10
Finally, the area is given by:
A = w * l\\A = 10 * 14\\A = 140 ft ^ 2
Answer:
he should order 140 square feet
.895
21.48 divided by 24 is .895 or rounded it is .9
