Answer:

a. -7
b. -20
c. 7

Step-by-step explanation:

a. -9+2, in this case, it is -7 because you take the bigger number and subtract it by the lower number. If the bigger number is negative your answer will be negative, if the bigger number is positive it will be positive it is just really a basic subtraction problem just add the sign.
b. In multiplication +++=+ ++-=- and a -+-=+ do your problem without thinking about the signs and then add the signs with the formula I showed you.

c. ---=+

Answer:

c - 39

Step-by-step explanation:

Given,

-4 (8 - c ) - (3c + 7 )

= -4 ( -c + 8 ) - (3c + 7 )

= 4c - 32 - ( 3c + 7 )

= 4c - 32 - 3c - 7

= ( 4 - 3 )c + ( -32 - 7 )

= c + ( -32 - 7)

= C - 39

Ricardo has saved 83% of the money he needs to buy a new skateboard that costs $150. How much MORE does he need to save to buy t

4vir4ik [10]

Answer:

17%, or $25.50

Step-by-step explanation:

If Ricardo has already saved 83% of the money, then he needs to save 17% more, because 83% + 17% = 100%

So what you need to do to figure out the answer is to find out 17% of $150

You first have to convert 17% into decimal form which is 0.17.

Then, you multiply 0.17 × 150 = 25.5

Ricardo needs $25.50 to buy the skateboard.

Hope this helped.
