Answer:
<h2>C. $1,689.00</h2>
Step-by-step explanation:
Let the amount spent by Tim be x and the amount spent by Nikko be y
If Tim spent $55 more than 2/3 of the amount that Nikko spent for his computer, then amount spent by Tim will be x = 55+2/3 y
Since the total amount that Tim and Nikko spent for their computers was $2,870 then;
x+y = $2,870
Substituting x = 55+2/3y into the equation above, we will have;
55+2y/3 + y = 2,870
(165 + 2y)/3 + y = 2,870
(165 + 2y+3y)/3 = 2,870
cross multiply
165 + 2y+3y = 3*2870
165+5y = 8610
5y = 8610-165
5y = 8445
y = 8445/5
y = 1689
<em>Hence Nikko spent a sum of $1,689.00 on his computer.</em>
Answer:
wow thats one hard equationnnnn
Step-by-step explanation:
Answer:
X + 8 = 8 + X is the correct answer
Answer is choice C. The reason why is because we're simply moving parenthesis around to regroup terms
(10)(5x)(7) = (10*5)(x*7)
We've grouped up the 10 and 5 together; we've also grouped up the x and 7 together.
Side Note: The specific rule being used is the associative property of multiplication. Algebraically that rule is a*(b*c) = (a*b)*c
There wouldn’t be any forward progress if it was taken literally because it would mean you have take 23 steps backwards with 23 steps forwards.
Answer: -23
