Answer:
$150.66
Step-by-step explanation:
Let that amount of money Roger has = x
The amount of money Roderick has = y
Roger has four dollars more than double the amount that Roderick has in his wallet.
x = 2y + 4
Together, they have a total of $224.
x + y = $224....... Equation 1
We substitute 2y + 4 for x in Equation 1
2y + 4 + y = $224
3y + 4= $224
3y = $224 - 4
3y = $220
y = $220/3
y = $73.333333333
y = $73.33
How much money does Roger have?
x = 2y + 4
x = 2(73.33) + 4
x = $146.66 + 4
x = $150.66
Roger has $150.66
Answer:
A.
Step-by-step explanation:
First write the picture down like so:
x(8) divided by 10.9 - 7.9 then go down the row wel 10.9 x 8 = 87.2 divide that by 10.9 and youll get 8 then subtract 8 from 7.9 and you will get 0.1
The first one is: n=39
Reduce the fraction with 8
1/2=n/78
Simplify the equation using cross-multiplication
78=2n
Swap the sides of the equation
2n=78
Divide both sides of the equation by 2
Final answer: n=39
Second one: 125/25=60/x
Reduce the fraction with 25
5=60/x multiply both sides of the equation by x, 5x=60, Divide both sides of the equation by 5, final answer: x=12
