Let x and y represent the smaller and larger numbers, respectively.
y - x = 5 . . . . . the difference is 5
3y = 4x + 6 . . 3 times the larger is 4 times the smaller plus 6
Add x to the first equation to get an expression for y.
y = x + 5
Use that in the second equation.
3(x + 5) = 4x + 6
3x + 15 = 4x + 6 . . . . . eliminate parentheses
9 = x . . . . . . . . . . . . . . add -3x-6
y = x+5 = 14
smaller number: 9
larger number: 14
Answer:
No, he is not correct
Step-by-step explanation:
To find the unit rate you need to .60 by 4. you will get 2.4, which is the
unit rate. he rides his bike 2.4 mph.
1 1/4 * 2 + 2 1/2 * 1.5
change the fractions to decimals
1.25 * 2 + 2.5 * 1.5
2.5+3.75
6.25
The total cost is 6.25
A. 9, 12, 15
9^2 + 12^2 = 15^2
81 + 144 = 225
225 = 225
3(5y + 6) - 4
First, distribute so that it will make the solving easier.
Second, since parentheses indicate multiplication, '3 × 5y = 15y'.
Third, multiply '3 × 6' to get '18'.
Fourth, subtract '18 - 4' to get '14'.

Answer:
C) 15y + 14
