Answer:
The two numbers are 3 and 5
Step-by-step explanation:
Multiply top equation by 4 to cancel out the Ys
Since X =5, we can plug it into either of the top two equations to find out the value of Y
To double check
Answer:
4 : 34
5 : 102
Step-by-step explanation:
This problem can be solved by using concept of co-interior angles.
co interior angles are those angles which lie on the same of parallel lines when the parallel lines are cut by transversal.
sum of co interior angles is 180 degrees.
In the problem 4 and 5 then angle given and missing angles are co-interior angles.
Problem 4
146 + ? = 180
? = 180 -146 = 34
Thus missing angle in problem 4 is 34 degrees
Problem 5
78 + ? = 180
? = 180 -78 = 102
Thus missing angle in problem 5 is 102 degrees
Answer: B and D
Step-by-step explanation:
Answer:
Depending on what the equation is,
x = (b (d + f)) / c
or
x = (d (b - f)) / c
Step-by-step explanation:
cx / d + f = b
If f is in the denominator (cx / (d + f) = b)
cx = b (d + f)
x = (b (d + f)) / c
If f is added after the fraction (cx/(d) + f = b)
cx/d = b - f
cx = d(b - f)
x = (d (b - f)) / c
The answer is 1/3 because 7 can go into 21 so then 7 goes into 7 one time and then it goes into 21 three times so then you would get 1/3
