<span>We could use 7+7=14 to find the sum of 6+7.
<u><em>Explanation</em></u><span><u><em>: </em></u>
7+7=14 is one of the two closest doubles to 6+7.
We know that:
7 is 1 more than 6; this means:
7+7 will be 1 more than 6+7.
7+7=14, so finding 1 less,
6+7=13.</span></span>

Answer:
87.9
Step-by-step explanation:

Formula of direct variation is: y = kx
k is the constant of variation
y is the total value that is directly varies with the changes in x.
in this case. x is represented by a. y is represented by b.
A.) b = 0.7a ⇒DIRECT VARIATION with 0.7 as the constant of variation
B.) b = 1/8 a⁻³ ⇒ Not a direct variation. Because a has a negative exponent
C.) 5(1/a) = b ⇒ Not a direct variation
D.) 1a = b ⇒ DIRECT VARIATION with 1 as the constant of variation
The price of the computer is 4 285 dollars which you borrowed for an installment plan.
Let's solve for the APR and the monthly payment.
The interest charge is 513.26 dollars for 36 months
=> 36 months = 3 years
=> 513.26 / 3 years = 171.1 dollars per year is the interest.
=> 4 285 + 513.26 = 4 798.26 dollars
=> <span> 4 798.26 dollars /3 years = 1599.42 dollars per year
</span>=><span>599.42 dollars / 12 months 133.29 dollars per month</span>
