Eric forgot to add 2 to both sides.
Step-by-step explanation:
He forgot to add 2 to both sides so that he cancel out the -2 from the equation. Then the equation would become 2/5v=6 the you would divide those two and your answer would be 1/15.
find the value of m!!!
Answer:
[tex]m=158[/tex]
Step-by-step explanation:
Angles on a straight line add up to 180 degrees.
Hence,
[tex](m-29)+51=180[/tex]
Remove brackets:
[tex]m-29+51=180[/tex]
[tex]m+22=180[/tex]
Subtract 22 from both sides:
[tex]m+22-22=180-22[/tex]
[tex]m=158[/tex]
Answer:
[tex]\displaystyle 158 = m[/tex]
Step-by-step explanation:
Both angles form a linear pair, making them supplementary angles. This means you set both expressions equivalent to one hundred eighty degrees:
[tex]\displaystyle 180° = 51° + [m - 29]° \hookrightarrow 180° = [m + 22]° \\ \\ \boxed{158 = m}[/tex]

A circular plot of diameter 28m is surrounded by a path of uniform width. If the area of the path is 346.5^2, find the width of the path.
Answer:
the width of the path is 2.81 m
Step-by-step explanation:
given:
A circular plot of diameter 28m is surrounded by a path of uniform width
If the area of the path is 346.5^2
find:
the width of the path.
---------------------------------
dia of circle = 28m
let Si = side of inner square path = 28 m
let So = outer side of square path = ?
1st step
is to get the total area
At = area of path + area of inner square
At = 346.5 + (28 x 28)
At = 1130 m²
2nd step
get the outer side of square path So
At = So²
1130 = So²
So = √1130
So = 33.62 m
lastly solve the width of path:
Width (w) = (So - Si)/2
w = (33.62 m - 28 m) / 2
w = 2.81 m
therefore,
the width of the path is 2.81 m

solve for r
negative 13 equals r over 9 plus eight
Answer:
r = - 189
Step-by-step explanation:
Given
- 13 = [tex]\frac{r}{9}[/tex] + 8 ( subtract 8 from both sides )
- 21 = [tex]\frac{r}{9}[/tex] ( multiply both sides by 9 )
- 189 = r
Answer: r= -189

(-6) + (-4) = -6 - 4 = -10 (N)
(+6) + (-2) = 6 - 2 = 4 (P)
Part 2:(-7) + (+1) + (+2) = -7 + 1 + 2 = -4
(-2) + (-4) + (+3) = -2 - 4 + 3 = -3
(+5) + (+3) + (-1) + (-4) = 5 + 3 - 1 - 4 = 3
(-4) + (+3) + (-2) + (-6) = -4 + 3 -2 - 6 = -9

mushrooms at $0.10 each. She spends a total of $6.10 on the pizza. Write an equation to model the number of
pepperonis she put on the pizza.
Answer:
Step-by-step explanation:
Base=4
Mushroom =0.10×8=0.80
0.80+4=4.80
6.10-4.80=1.30
1 pepperoni =0.13

Lynn is making custom bricks. She combines 39 pounds of water and 48 pounds of brick dust in a mixing bucket. She spills 13 pounds of the mixture while stirring the contents. The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture, and the leftover mixture is washed out of the mixing bucket.
What is the greatest number of bricks Lynn can make?
___ bricks
How many pounds of mixture will be washed out of the bucket if Lynn makes the greatest number of bricks?
___ pounds
Answer:
A. 10 bricks
B. 4 pounds
Step-by-step explanation:
Water = 39 pounds
brick dust = 48 pounds
Total mixture = water + brick dust
= 39 + 48
= 87 pounds
She spills 13 pounds of the mixture while stirring
Remaining mixture = Total mixture - Spillage
= 87 pounds - 13 pounds
= 74 pounds
The mixture is then poured into small dirt holes to make bricks. Each brick requires 7 pounds of mixture
Number of bricks made = Remaining mixture / pounds per brick
= 74 pounds / 7 pounds
= 10 bricks remaining 4 pounds of the mixture
A. What is the greatest number of bricks Lynn can make?
10 bricks
B. How many pounds of mixture will be washed out of the bucket if Lynn makes the greatest number of bricks?
4 pounds

The telephone company offers two billing plans for local calls. Plan 1 charges $38 per month for unlimited calls and Plan 2 charges $18 per month plus $0.04 per call.
The question is incomplete:
The telephone company offers two billing plans for local calls. Plan 1 charges $38 per month for unlimited calls and Plan 2 charges $18 per month plus $0.04 per call.
Use an inequality to find the number of monthly calls for which plan 1 is more economical than plan 2.
Answer:
Plan 1 is more economical than plan 2 when you make more than 500 monthly calls.
Step-by-step explanation:
Plan 1 costs $38 per month for unlimited calls and plan 2 costs $18 per month plus $0.04 per call which is: 18+0.04x and you can infer that plan 1 would be cheaper when you have to pay more than $38 using plan 2 and you can express it with the inequality:
18+0.04x>38, where x is the amount of monthly calls
Now, you can solve for x:
0.04x>20
x>20/0.04
x>500
According to this, plan 1 is more economical than plan 2 when you make more than 500 monthly calls.

Find three consecutive odd integers where the sum of the two largest is seven less than three times the smallest.
Answer:
13, 15, 17Step-by-step explanation:
x - an integer then 2x + 1 is an odd number (the smallest one)
consecutive odd numbers increase by 2
so the next odd number (the middle number) is:
2x + 1 + 2 = 2x + 3
and the third (the largest) consecutive is:
2x + 3 + 2 = 2x + 5
the sum of the the two largest numbers is:
2x + 3 + 2x + 5
3 times the smallest number is:
3(2x + 1)
the sum of the two largest is seven less than three times the smallest, so:
2x + 3 + 2x + 5 = 3(2x + 1) - 7
4x + 8 = 6x + 3 - 7
-6x -6x
-2x + 8 = -4
-8 -8
-2x = -12
÷(-2) ÷(-2)
x = 6
2x+1 = 2•6+1 = 13
2x+3 = 2•6+3 = 15
2x+5 = 2•6+5 = 17
Check:
2x+3+2x+5 = 15+3+15+5 = 38
38+7 = 45
