5 0

Answer: -9

Step-by-step explanation:

"3 times -3" indicates a multiplication. Then, rewriting it, this is:

(3)(-3)

Now, in order to solve the given multiplication, the first thing you need to remember is multiplication of signs:

(+)(+)=+\\(-)(-)=+\\(+)(-)=-

Notice that one factor is positive and the other one is negative. Then, the product will be negative.

Therefore, the product is:

 (3)(-3)=-9

A customer buys a CD for $15 and a video game. The customer pays a total of $42.80 for the two items, which includes 7% sales ta
kari74 [83]

Answer:

1.07 (15 + x) = 42.80

Step-by-step explanation:

Given data

CD= $15

Let the cost of the video game be x

The total cost= 15+x

Hence the equivalent expression is

1.07 (15 + x) = 42.80

open bracket

16.05+1.07x= 42.80

42.80-16.05= 1.07x

26.75=1.07x

x= 26.75/1.07

x= 25

Check

7% tax for CD

=0.07*15

=1.05

total =1.05+15

=$16.05

7% tax for Video game

=0.07* 25

=1.75

total =1.75+25

=$26.75

In all

=26.75+16.05

=$42.8

abruzzese [7]

Answer:

Ella sold the each print for the cost of $57.21.

Step-by-step explanation:

The total number of prints sold at gallery = 52

Total amount it is sold for = $2,975

Noe, If 52 prints are sold for $2,975.

⇒\textrm{Cost of 1 print} =  \frac{\textrm{Total cost of 52 prints}}{\textrm{52}}

= \frac{2,975}{52}  = 57.21

or, Cost of 1 print = $57.21

So, Ella sold the each print for the cost of $57.21.
