Really need help <br> Five less than twice what negative number squared is 157?
Cerrena [4.2K]

Answer:

-9

Step-by-step explanation:

2(-x)² - 5 = 157

2x² - 5 = 157

add 5 to each side of the equation:

2x² = 162

divide both sides by 2:

x² = 81

√81 = 9 or -9

A candy store sells bags of fruit-flavored candy for $2 and chocolate candy for $3. Jasmine spends $54 on candy for her friends.
34kurt

Answer:

2x + 3y = $54

Step-by-step explanation:

Standard Form ~ Ax + By = C

A and B in this case are just going to be numbers, they are just for substitution purposes.

Since x is fruit flavored candy and y is Chocolate, we can substituce the Fruit for A and Chocolate for B.

Now, we have 2x + 3y = C

The C is going to be the total cost. Therefore we have ~

2x + 3y = $54

Have a great day,
