If the test is a major grade ( 60% of final grade) then around 73-75 but if the grade is worth a daily grade (40% of final grade) 78-82
Answer:
Gabrielle is 69 while Mikhail is 23.
Step-by-step explanation:
Let G represent Gabrielle's age and M represent Mikhail's age.
Gabrielle is three times Mikhail's age. In other words:
The sum of their ages is 92. In other words:
This is a system of equations. Solve. Substitute in G:
Thus, Mikhail is 23. Now, find Gabrielle's age:
Gabrielle is 69.
If the width is 3 on each side, that is 3 + 3 = 6.
26 - 6 = 20.
There are two sides left: 20 divided by 2 = 10.
10+10+3+3 = 26.
The length is 10.
$1200+ $1400 = 2600
Answer:
1200 : 1400 = 6 : 7
The ratio is not in lowest terms so we found an equivalent ratio by simplifying.
Solution:
We can simplify the ratio 1200 : 1400 by dividing both terms by the greatest common factor (GCF).
The GCF of 1200 and 1400 is 200.
Divide both terms by 200.
1200 ÷ 200 = 6
1400 ÷ 200 = 7
Therefore:
1200 : 1400 = 6 : 7
For #27 its 3d=144, then you divide 144 by 3 which gives you 48 so its 48 days
