Answer:

X=5 and y=-6

Step-by-step explanation:

Positive five cancels out -5 and—6 cancels out positive six, so you are left with 0 which equals 0.

Solve the following multiplication problem. 11 cu. yd. 17 cu. in. × 135

Gekata [30.6K]

Answer:

69,286,455 cu inches

Step-by-step explanation:

Step 1: Convert yards to inches

1 cu yard = 46656 cu inches

11 cu yard = y cu inches

Cross multiply

y = 11 x 46656

y = 513216 cu inches

Step 2: Find total inches

513216 + 17 = 513233 cu inches

Step 3: Multiply total inches by 135

513233 x 135 = 69,286,455 cu inches

Solve each given equation and show your work. Tell whether it has one solution, an infinite number of solutions, or no solutions

WITCHER [35]

Solve 6x+4x-6=24+9x. Combine all the x terms on one side and all the constants on the other:

10x-9x = 24+6, or x = 30. ONE soution.

Solve 4x+8=2x+7 +2x-20. Combine all the x terms on one side and all the constants on the other: 4x - 2x - 2x = 7 - 20 - 8 => 0 = -21

This is NEVER true, so 4x+8=2x+7 +2x-20 has NO SOLUTION.

Please try solving equation B yourself. Then I'd gladly comment on your work.
