Write an algebraic expression to represent each phrase:
a. 4 more 7 times a number
b. 4 more than a number, then multiply the result by 7

A. 7n+4 B. (n+4)7

Step-by-step: A. Put it in simplest form(7n+4) or your teacher might count it wrong.

B. Make sure to use parentheses to tell them to do it first so when using PEMDAS or GERMDAS they don’t do the multiplication first, but the groups.

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
