Answer:
7
Step-by-step explanation:
Total concrete for slabs
24 * 24 * 1 = 576 ft³
Additional 20 %
By rule of three
if 576 ⇒ 100
x?? ⇒ 20 x = 115,2
And there are 2 slabs, the total volume of concrete is:
Q(t) = 2* (576 + 115,2 ) Q(t) = 1382,4 ft³ (1)
If the truck can carry a maximum of 8 yd³, as 1 ft³ = 0,037 yd³
then a truck can carry a maximum of
8/ 0,037 = 216,21 ft³
Now the total quantity is 1382,4
Then
1382,4/216,21 = 6,39
And as nobody can send a fraction of a truck , the fewest number of truck is 7
Answer:
(x,y) ⇒ (x - 3) (y - 4)

Answer:
80/89
Step-by-step explanation:
<u />
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*(2*x-6)-(10*x-6)=0
2x - 6 = 2 • (x - 3)
8 • (x - 3) - (10x - 6) = 0 -2x - 18 = -2 • (x + 9)
-2 • (x + 9) = 0 Solve : -2 = 0
<span>This equation has no solution.
</span>A a non-zero constant never equals zero.
Solving a Single Variable Equation :
Solve :
x+9 = 0 <span>
</span>Subtract 9 from both sides of the equation :<span>
</span> x = -9
