Answer:
No solutions
Step-by-step explanation:
Let's solve your equation step-by-step.
3(6d−24)=6(12+3d)
Step 1: Simplify both sides of the equation.
3(6d−24)=6(12+3d)
(3)(6d)+(3)(−24)=(6)(12)+(6)(3d)(Distribute)
18d+−72=72+18d
18d−72=18d+72
Step 2: Subtract 18d from both sides.
18d−72−18d=18d+72−18d
−72=72
Step 3: Add 72 to both sides.
−72+72=72+72
0=144
Answer:
There are no solutions.
Step-by-step explanation:
d = z - 9
d = 10 - 9 ----> substitute
d = 1
Answer: A
Step-by-step explanation:
Subtract 12 from both sides:
y + 15 - 15 < 3 - 15
Simplify:
y < -12
Answer: Height = 20 inches
Width = 14 inches
Step-by-step explanation:
The aquarium is rectangular. The formula for determining the volume of a rectangular box is expressed as
Volume = LWH
Where L,W and H represents the length, width and height of the box.
The aquarium holding African cichlids is 6 inches higher than it is wide. It means that
H = W + 6
Its length is 33 inches, and its volume is 9240 cubic inches. It means that
9240 = 33W(W + 6)
9240/33 = W(W + 6)
280 = W² + 6W
W² + 6W + (6/2)² = 280 + (6/2)²
(W + 3)² = 280 + 9 = 289
Taking square root of both sides, it becomes
W + 3 = √289 = 17
W = 17 - 3
W = 14
H = W + 6 = 14 + 6
H = 20
