5 is the correct answer I believe
4/5x + 4/3 = 2x....there are 2 ways to do this...one with fractions, one without.
with :
4/5x + 4/3 = 2x
4/3 = 2x - 4/5x
4/3 = 10/5x - 4/5x
4/3 = 6/5x
4/3 * 5/6 = x
20/18 = x
10/9 = x
without :
4/5x + 4/3 = 2x....multiply by common denominator of 15
12x + 20 = 30x
20 = 30x - 12x
20 = 18x
20/18 = x
10/9 = x
Answer:
Final cost = 0.9328y
Step-by-step explanation:
Assume,
Original price = y
Given:
Discount = 22%
Sales tax = 6%
Computation:
Sales tax will be added on sale value
So,
Sales price = y[100%-22%]
Sales price = 0.88y
Price after sales tax :
Final cost = 0.88y[100% + 6%]
Final cost = 0.88y[106%]
Final cost = 0.9328y
Answer:
x = 65
Step-by-step explanation:
The angle labeled with the expression " ( 2x + 15 ) " and the angle with the measure of 145° are vertical angles
Vertical angles are congruent (In other words, they are equal to each other)
Hence, 2x + 15 = 145
^ ( Note that we just created an equation that we can use
to solve for x )
Using that same equation we then solve for x
2x + 15 = 145
step 1 subtract 15 from each side
15 - 15 cancels out
145 - 15 = 130
we now have 130 = 2x
step 2 divide each side by 2
130 / 2 = 65
2x / 2 = x
we're left with x = 65
Divide the 6/7 of a gallon by 4
(6/7) ÷ 4
flip and multiply
(6/7) × (1/4) = 6/28
simplify
6/28 = 3/14 gallon for each kid
