Answer:
True because when you multiply the 2 by everything in the parentheses you get 4x + 6y which is 4x + 6y = 4x + 6y. and when you solve it you'll get 0 = 0

Answer:
The measure of angle x is 50 degrees
Step-by-step explanation:
we know that
----> equation A
----> equation B
solve the system by substitution
substitute equation B in equation A
solve for y
Find the measure of angle x
therefore
The measure of angle x is 50 degrees

Step-by-step explanation:
(x-5)+x=37
2x=42
x=21
21-5=Harriet's Age
Answer:
120
Step-by-step explanation:
As x goes from 1 to 2, y increases by 4 from 4 to 8
As x goes from 2 to 3, y increases by 4 from 8 to 12
We increase by 4 each time
The formula for an arithmetic sequence is
an = a1+d(n-1)
where a1 is the first term which is 4
d is the common difference or the number we add each time which is 4
n is the term we are looking for which is 30
a30 = 4 +4 (30-1)
a30 = 4+4(29)
= 4+116
= 120
Divide both sides by -5 to get x= -13
