Let
x----------> <span>Aidan's age
y----------> M</span><span>aggie's age
we know that
x=4
x=(y/2)-6
so
substitute
4=(y/2)-6----> multiply by 2-----> 8=y-12----> y=8+12-----> y=20
the answer is
</span>M<span>aggie's age is </span><span>20</span>
Answer:
Yes, Chloe fill out her math journal correctly.
Step-by-step explanation:
Total number of math problem = 100
Problems solved on Friday = × 100 = 39
Problems solved on Saturday = × 100 = 50
Problems solved on Sunday = 15
Total number of math problem in three days = 39 + 50 + 15 = 104
But the student have only 100 math problems to solve in three days . so he achieved the target. thus Chloe fill out her math journal correctly.
Answer:
84 degrees
Step-by-step explanation:
Angle A = 83 degrees
Angle B = x degrees
Angle C = 135 degrees
Angle CDE = 122 degrees
We know that the four inner corners of a quadrilateral should add up to 360 degrees. Two supplementary angles will add up to 180 degrees. Adjacent angles on a straight line will always be supplementary. Knowing this, just solve for <ADC and add that amount to <A and <C. Then, subtract that sum from 360 degrees.
<ADC = 180-122 = 58
58+83+135 = 276
360-276 = 84 degrees
I think the second one because if you cancel out the 4 then it leaves u with -2 and 5 and if u add them it leaves you with 3 not sure
