On monday angela ate some grapes, tuesday she ate 6 more than the day before. each day of the week she ate 6 more than the day before. she finished off her grapes on friday she had eaten 100.
how many grapes did she eat on monday?

Step-by-step explanation:

You have to use this equation, we don’t know how much she ate Monday so that is x, or really any letter. 6 to the seventh power is, 6•6•6•6•6•6, so multiply that and add 6 to the product until you get 10, and find out how many extra 6’s you added to the product.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
