The answer to question #1 is 11:

√x² = √121

√x² = x
√121 = 11

So the answer is x = 11.
==========================================================

For the second question, I don't know what the exact answer is, but I do know that it is one of the options with 8/3. I can't figure this out because I don't know how to do √x³. Here was the work that I did do:

√64        8           Based on this, I would say the answer has to be positive 8/3. 
------- = ----- 
√27       3√3

A torch and a battery cost £2.50 altogether. The torch costs £2.00 more than the battery.
Hitman42 [59]

Answer:

1/5

Step-by-step explanation:

To find what fraction of the total price the battery is, we need to find out how much the battery alone is first.

Since the battery and torch together are £2.50 and the torch is £2.00, we can find the price of the battery by subtracting the total price to the price of the torch.

Battery Price = £2.50 - £2.00

Battery Price = £0.50

The fraction value of the torch is:

2.00 of 2.50 = 4/5

That then leaves us with:

0.50 of 2.50 = 1/5

To check we need to add the two fractions together.

1/5 + 4/5 = 5/5 or 1

Steve picks 55 pounds of pears. He packs an equal amount of pears into 6 bags. He then has 4 pounds of pears left. What is the w
Serggg [28]
Because he has 4 pounds of apples left, you are to subtract that from the total pounds picked, which was a total of 55 pounds. So 55 with 4 taken away, or 55 - 4, equals 51. Since he had equally put 51 pounds into six bags, you are to then divide . 51 / 6 = 8.5. He had put 8.5 pounds worth of apples into each bag.

Solve the system equations. <br> X+2y=0<br> 10y=-5
nexus9112 [7]

Answer:

x=1

y=-1/2

Step-by-step explanation:

x+2y=0....(1)

10y=-5.....(2)

From (2) we can find y.

y=-5/10

y=-1/2

Use that in (1)

x+2*(-1/2)=0

x-1=0

x=1
