Answer:
The answer is 44.
Step-by-step explanation:
1.5x - 3 = 63
then solve for x to get the answer : 44
Answer:
16,800 Liters
Step-by-step explanation:
Convert 3/4 into eighths, because it was already 1/8 full before the 10,500 liters were added:
3/4= 6/8
Subtract 1/8 from that (because it was already 1/8 full):
6/8-1/8= 5/8
Divide 10,500 by the 5 (because you want how many liters each part is):
10,500/5= 2,100
You know can say that every eighth is 2,100 Liters of water.
Multiply that by the 8 total parts it can hold:
2,100x8= 16,800 Liters
Answer:
I think its 3 cus 4 +8 = 12 , 2 x 2 is 4 then 12 / 4 is 3

Answer:
<h2>SA = 5645cm²</h2>
Step-by-step explanation:
We have three pairs of congruent rectangles
9cm × 4m; 9cm × 5cm and 4m × 5cm
We know 1m = 100cm, therefore 4m = 400cm
The formula of an area of a rectangle l × w:
A = l · w
Substitute:
A₁ = 9cm · 4m = 9cm · 400cm = 3600cm²
A₂ = 9cm · 5cm = 45cm²
A₃ = 4m · 5cm = 400cm · 5cm = 2000cm²
Calculate the surface area:
SA = A₁ + A₂ + A₃
SA = 3600cm² + 45cm² + 2000cm² = 5645cm²
Answer:

Step-by-step explanation:
3y = -9
Divide each side by 3
3y/3 = -9/3
y = -3
