Answer:
PEMDAS.
parenthesis first, then exponents, next would be mutiplication/division, then lastple add/subtract.
Step-by-step explanation:
first would be 15-7, then the 3^2, etc
16
Explanation:
Quotient of 6 and 3 indicates division
6 / 3 = 2
Eight times the quotient
8 * 2 = 16
<span>First we add 2m to both sides, leaving 7m + 72 = 52 (since -2m + 2m cancels out). Next, we subtract 72 from both sides, bringing us to 7m = -20. Solving for m, we get -20/7. Since this is not one of the listed options, it is possible that the original poster has made a typographical error.</span>
Answer: y= Y/x = ?
Step-by-step explanation: write the equation like said, and use the numbers you get to fill in. So say you traveled 500 miles , and you had 540 miles till empty yku would have 40 miles left , so you traveled 500 miles per gallon of gas :) hope this helps
Answer:
4 seconds
Step-by-step explanation:
using the vertex formula of a quadratic,
, where (h,k) is the vertex
h is height and t is time in seconds
the vertex (maximum height) of the dolphin is (h,k) or (0.5, 2)
Height of 1/2
time of 2 seconds
it will take 2 additional seconds to reach the water again.
this can also be solved using quadratic equation, but since it was already set up in vertex form, i'd use that.
