Answer:
72
Step-by-step explanation:
Consecutive even integers have a difference of 2 between them
let n be the first integer, then
n + 2, n + 4, n + 6 are the second, third and fourth, then
n + 2 + n + 6 = 76 ( sum of second and fourth )
2n + 8 = 76 ( subtract 8 from both sides )
2n = 68 ( divide both sides by 2 )
n = 34
Thus the 4 even integers are
34, 36, 38, 40
sum of first and third = 34 + 38 = 72
Answer:
$7,000
Step-by-step explanation:
Let 
equal the original price.
Combine like terms.
Divide by the coefficient of , which in this case is 
If you like the variable on the left, rewrite:
When they ask for combining the variable terms, you take one of the variable terms and move to the other side of the equation and change its sign. From there, you cross multiply those variable terms and simplify. Once you simplify, you look at the denominator and that will be your answer.
Similarly for the constant terms, you take one of the constant terms and move to the other side of the equation and change its sign. Again, you cross multiply these two constant terms and simplify. The denominator you get after simplification will be your answer.
Use a 9 instead of a ten. for example, 7/(9 x 10) = 7/90
