Easy question i will mark braineliest

Answer:

Step-by-step explanation:

$5(y - 3.8) = 4.7(y - 4)$

Distribute 5 through the parentheses

$5y - 19 = 4.7(y - 4)$

Distribute 4.7 through the parentheses

$5y - 19 = 4.7y - 18.8$

Move ' 4.7 y ' to L.H.S and change it's sign

$5y - 4.7y - 19 = - 18.8$

Move constant to R.H.S and change it's sign

$5y - 4.7y = - 18.8 + 19$

Collect like terms

$0.3y = - 18.8 + 19$

Calculate

$0.3y = 0.2$

Divide both sides of the equation by 0.3

$\frac{0.3y}{0.3} = \frac{0.2}{0.3}$

Calculate

$y = 0.67$

Hope this helps...

If the price of an object dropped 75% down to $85.99 what was the original price?

Serggg [28]

If the price of an object drastically dropped 75%, then the dropped price is equal to 25% of the original price. That means that to find the original price, we have to multiply by the reciprocal of 25% (4). The original price would be $85.99 * 4 which is $343.96.

p varies directly as q and inversely as r. One set of values is p = 5, q = 1, and r = 2. Find p when q = 10 and r = 50.

kari74 [83]

P = kq/r

5 = k*1/2
k = 2*5 = 10

p = 5*10/50 = 1
P is 1.

Hope it helps!

A soccer field is 345 feet long.What is the length of the field in yards?

OleMash [197]

115. This is because there are three feet in a yard. If you divide the number of feet by three, you can find the number of yards. Therefore, 345 divided by 3 equals 115.
