Answer:
13 and 32
Step-by-step explanation:
let one number be x
Then the other number is x + 19 , then
x + x + 19 = 45
2x + 19 = 45 ( subtract 19 from both sides )
2x = 26 ( divide both sides by 2 )
x = 13
The 2 numbers are 13 and 13 + 19 = 32
Answer:
210 pounds
Step-by-step explanation:
First, we are going to find the exchange rate from dollars to pounds.
We know form our problem that 800 dollars are 560 pounds. so:
\frac{560pounds}{800dollars} =0.7
800dollars
560pounds
=0.7 pounds per dollar.
Next, we are going to multiply our exchange rate by the number of dollars we want to change, 300:
300dollars*\frac{0.7pounds}{dollar} =210pounds300dollars∗
dollar
0.7pounds
=210pounds
We will get 210 pounds for 300 dollars
