Answer:
7/15
Step-by-step explanation:
Determine how much she has watched.
1/3 + 1/5 The common denominator of 3 and 5 is 15. Multiply each fraction by an amount that will make the denominator 15
1/3 = 1*5/(3*5) = 5 / 15
1/5 = 1*3 / (5*3) = 3/15
Now add the two fractions together.
5/15 + 3/15 = 8/15
What is left of the movie? The whole movie = 1 so that which is left is
1 - 8/15
15/15 - 8/15
7 / 15
She has just a bit under 1/2 to go.
Product is times so try that as it’s the product of a number
Answer:
-31/6
Step-by-step explanation:
77+2(3x-5)=8-3(2x+1)
77+6x-10=8-6x-3
77-10+6x=8-3-6x
67+6x=5-6x
67+6x-(-6x)=5
67+6x+6x=5
67+12x=5
12x=5-67
12x=-62
x=-62/12
simplify
x=-31/6

linear equation, variables
Step 1
Define the variables
Let
x-----> number of erasers
y-----> total cost
we know that
------> this is the linear equation that represent the situation
therefore
the answer is y = 0.84 + (0.38)x
