If 4 numbers have an average of 9, then total of the 4 numbers is 4 * 9 = 36.
If one of the 4 numbers is a 7, then
7 + x = 36 where x is the sum of the other 3 numbers.
7 + x = 36 Subtract 7 from both sides
7- 7 +x = 36 - 7
x = 29
Answer 29
Answer:
One Angle = 110°
Other Angle = 70°
Step-by-step explanation:
A linear pair means that two angles are in a straight line (or, a straight angle).
A straight line is 180 degrees.
THey are supplementary.
We can say one angle is "a" and another one is "b".
<em>One angle is 10 MORE THAN 2/3rds of the other, we can write:</em>
<em>
</em>
<em />
<em>Also, since they are supplementary (add up to 180), we can write:</em>
<em>a + b = 180</em>
<em />
We can now substitute 1st equation in this one and find b:

Since a + b = 180, we can write:
a + 110 = 180
so,
a = 180 - 110
a = 70
Thus,
One Angle = 110°
Other Angle = 70°
Answer:
4/5
Step-by-step explanation:
if 1/4 of x is 1/5 that means there is 4 sets of 1/5
so 4*1/5= 4/5
your answer is 4/5
