X+y=70
x=2y-5
x=larger number
y=smaller number
now plug in the value of x to only have one variable in the equation...
Way to solve for y:
(2y-5)+y=70
3y-5=70
add 5 on both sides...
3y=75
divide by 3 on both sides
y=25
1st way to solve for x:
now plug in y in the original equation...
x+25=70
subtract 25 on both sides...
x=45
2nd way to solve for x:
plug in y for the second equation...
x=25(2)-5
x=50-5
x=45
answer: the two numbers are 45 and 25.
Jacob found 0.6 pears, I know this because 6 divided by 10 is 0.6.
6. if the number is 91.8, your answer is 459
7. 50 percent
8. 85 percent
To convert a percentage to a decimal we divide it by 100. So, 5% = .05
To find the tax, multiply the cost by the tax rate
(.05)(11.20) = 0.56
Add this to the cost to get the total
$11.20 + $0.56 = $11.76
