To answer this question you need to add 20 minutes to 5 times 800, which equals 4020, then you divide 4020 by 60 and your answer is 67!
Gabrielle's age is 3x (in which x is mikhail's age)
the sum is 56 so 3x+x=56
3x+x=56
4x=56
x=14
since x was mikhail's age, mikhail is 14 years old
Answer:
It would be worth $5,040 after 7 years
Step-by-step explanation:
Multiply 40% by 7 and get 280, then turn it into a percent, .280, finally multiply it by $18,000 to get $5,040
1x + 4y = 11 ⇒ 5x + 20y = 55
5x - 7y = -10 ⇒ <u>5x - 7y = -10</u>
<u>27y</u> = <u>65</u>
27 27
y = 2¹¹/₂₇
x + 4(2¹¹/₂₇) = 11
x + 8²²/₂₇ = 11
<u> - 8²²/₂₇ - 8²²/₂₇
</u> x = 2⁵/₂₇
(x, y) = (2⁵/₂₇, 2¹¹/₂₇)
