Solve for the value of x in this equation: 146=2+7x+5x
Answers
Answer:
x=12
Step-by-step explanation:
First combine like terms
146=2+12x
Then I like to put it into y=mx+b form.
146=12x+2
Next you subtract 2 from both sides.
146-2=12x+2-2
144=12x
Finally you divide 12 on both sides and in the end you get x=12. Hope this helps.

12 - 20a + 4 = 6a + 12 - 4a
-8a + 4 = 2a + 12

[tex]12a - 4(5a - 1) = 2(3a + 6) - 4a[/tex]
let us trace the solution line by line
[tex]line-one=12a - 4(5a - 1) = 2(3a + 6) - 4a\\\\line-two=12a - 20a + 4 = 6a + 12 - 4a\\\\[/tex]
collect like terms

Billy ran 3/4 mile on Monday and 7/8 mile on Tuesday. How many miles did he run altogether
Answers
Answer:
The total distance =13/8Step-by-step explanation:
Step one:
given data
distance ran on monday=3/4miles
distance ran on tuesday=7/8miles
The total distance ran altogether= distance ran on monday+distance ran on tuesday
The total distance =3/4+7/8
Strep two:
the LCM between the denominator 4 and 8 = 8
The total distance = 2(3)+1(7)/8
The total distance =6+7/18
The total distance =13/8
Hence the total distance =13/8 miles
The total miles Billy ran altogether on Monday and Tuesday is 13/8 miles
Given:
Monday = 3/4 mile
Tuesday = 7/8 mile
Total miles = Monday + Tuesday
= 3/4 + 7/8
= (6+7) / 8
= 13/8 miles
Therefore, total miles Billy ran altogether on Monday and Tuesday is 13/8 miles

Graph A:
D ((y2-y1)/(x2-x1) or (y1-y2)(x1-x2))
Graph B:
A (same as above or simply take the rise divided by the run)
Answer:
1). Correct answer is D
2). Correct answer is A
Step-by-step explanation:
1).
For the points given, (-1, -1) and (2, -2), we have to find the slope.
Slope formula is (y2 - y1) / (x2 - x1), or rise over run.
Simply fill in the formula and you will get:
y2 = -2
x2 = 2
y1 = -1
x1 = -1
OR
(-2 - (-1)) / (2 - (-1)) which is D
2).
For the two points given, (2, 0) and (0, -3), find the slope.
Using the same equation above, (y2 - y1) / (x2 - x1), or rise over run, fill it in and solve and you will get your answer.
y2 = 0
x2 = 2
y1 = -3
x1 = 0
(0 - (-3)) / (2 - 0) = 3/2 which is A
