Scientists are studying the effects of increased temperature, which causes bleaching
on coral reefs. A scientist dives at two different
reefs, one located 34 feet below sea level and one
at 26 feet below sea level. Write and evaluate
a subtraction expression to find the change in
elevation needed in order for the diver to reach the
deeper reef.

3x + 4y -25 =0 represents the amount of change sianna should recieve

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%

choose (5, 1.5) and (-1.5,-3.5)

step-by-step explanation:

5 - 1.5 =3.5

-1.5 - (-3.5) = 2

3.5 + 2 =5.5

hope this !
