7x+6x=650
13x= 650
Divide by 13
X= 50
She saves 7(50)= 350
She speeds 6(50)=300
Answer:
Step-by-step explanation:
We can use exponent rules to try and simplify this expression down.
Exponent rules tell us that 
.
This means that since we have the same base on both terms (7 and 7), we can add the exponents to get a simplified expression.
So our simplified expression is 
.

Answer:
A) Isaac should get £ 10.75 in change.
B) The price of the e-scooter in the sale is £ 366.3.
Step-by-step explanation:
A) Given that Isaac buys 17 anti-pollution masks for £ 5.25 each, and he pays with five £ 20 notes, to determine how much change Isaac should get, the following calculation must be performed:
(20 x 5) - (17 x 5.25) = X
100 - 89.25 = X
10.75 = X
So Isaac should get £ 10.75 in change.
B) Given that the normal price of an e-scooter is £ 370 and, in a sale, there is 1 off the normal price of the e-scooter, to determine the price of the e-scooter in the sale the following calculation must be performed:
370 - (370 x 0.01) = X
370 - 3.7 = X
366.3 = X
Thus, the price of the e-scooter in the sale is £ 366.3.
