Answer:

Step-by-step explanation:

Use distribuitve property.

<u><em>DISTRIBUTIVE PROPERTY</em></u>

A(B+C)=AB+AC

A(B-C)=AB-AC

-3x-6x-8+5 ← (Group like terms & combine like terms.)

-3x-6x=-9x ← (Add and subtract elements to the numbers from left to right.)

-9x-8+5

-9x-8+5 ← (Solve & simplify)

-8+5 ← (Add & subtract.)

-8+5=-3

= -9x-3

$\Large\boxed{\mathsf{\Rightarrow -9x-3}}}$

Therefore, the correct answer is (C.) -9x-3.

A vcr and tv were bought for 8000 each. The shopkeeper made a loss of 4 per cent on vcr and 8 per cent prophit on the tv. Find t

aleksley [76]

Answer:

2% gain

Step-by-step explanation:

We assume the shopkeeper bought the appliances at the indicated prices, and that gain is computed on the basis of that cost price.

Since the base cost is the same for each appliance, the percentages can be added directly to find the percentage gain on 8000. However, the shopkeeper's total outlay was 16000, not 8000, so the final gain percentage is half of that total.

gain percent = (-4% + 8%)/2 = 2%

_____

If you want to see the actual numbers:

Loss on VCR = 4% × 8000 = 320.

Gain on TV = 8% × 8000 = 640.

Total gain on 16000 is -320 +640 = 320. As a percentage, that is ...

320/16000 × 100% = 2%

My teacher gave us the answers but we just need to show the work for solving the problems. Please help me

Radda [10]

Answer:

Step-by-step explanation:

16x + 22 = 134 ..... because if the two lines are parallel alternative exterior angles are congruent

16x = 134 - 22

16x = 112

$\frac{16x}{16} = \frac{112}{16}$

x = 7

hope it helps
