Mathematics
1 answer:
bulgar [2K]2 years ago
4 0

Answer:

C

Step-by-step explanation:

This might look strange, but I would begin by adding 4y to both sides.

12x = 20 + 4y          Subtract 20

12x - 20 = 4y           Divide both sides by 4

12x/4 - 20/4 = 4y/4 Combine

3x - 5 = y

A radio is being discounted 20% if the sale price of the radio is $51.44 what is the original price of the radio Radio is being
Grace [21]
Original price of the radio is $64.30

Sale price - $51.44
Discount rate - 20%

This means that $51.44 is the discounted price or is equivalent to 80% of the original price, since the 20% equivalent is deducted from the original price.

To get the original price, divide $51.44 by its corresponding percentage, 80%.

$51.44 / 80% = $64.30

To get the discount, multiply the original price by its discount rate

$64.30 x 20% = $12.86

To get the sales price, deduct the discount from the original price.

$64.30 - $12.86 = $51.44
100% - 20% = 80%

Bh+hr=25 solve for r please work it out step by step
denis23 [38]

So firstly, factor out h on the left side: h(b+r)=25

Next, divide both sides by h: b+r=\frac{25}{h}

Lastly, subtract both sides by b and your answer will be r=\frac{25}{h}-b
