7. Three sisters spent different amounts of money on their recent shopping spree. Ella spent $50 less than Ariel. Belle spent twice as much as Ella. How much did each sister
spend if they spent a total of $370?
A.) Define a variable.
B.) Write an algebraic expression for each of the given quantities.
Ariel:
Ella:
I Belle:
C.) Write and solve an equation.

2/3

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w

i think it might be a but you might want a second opinion
