To determine the expression that is equivalent to 8a + 20, all you have to do is find the common denominator and divide the values by it.
8a + 20
8a/4 + 20/4
4(2a + 5).
The correct solution would cue the second option - 4(2a + 5).
Answer:
Step-by-step explanation:
Solving (a):
7x - 19 and 3x + 14 are interior angles.
So:
Collect like terms
7x - 19 and 5y - 2 are equal angles --- corresponding angles
So:
Make 5y the subject
5y = 7x -17
Make y the subject
Substitute
Solving (b):
The triangle is right-angled.
So:

Answer: 170
Step-by-step explanation: 170x90% (0.9) = 153
Answer:
265
Step-by-step explanation:
The computation of the amount that should be make out together is shown below:
Let us assume the number of hours be x
And, the total money earned be y
Now the equation would be
y = 6x + 43
= 6(37) + 43
= 265
