distance traveled is directly
proportional to the time spent.
Write a direct variation equation.
A) x + 50 = y
B) y + 50x = 0
C) x= - 50 y
D) y = 50x

The length of a rectangle is 5 less than 3 times the width. What is the length?
Perimeter = 46 inches
Write an inequality or equation, then solve.
Answers
Answer:
Let the width of the Rectangle be x inches
Then, length is (3x-5) inches
Perimeter of the Rectangle= 46 inches (given)
According to the above problem,
Equation :---- Perimeter=2(length+breadth)
2{(3x-5)+x}=46
2(4x-5)=46
(4x-5)=46/2=23
4x=(23+5)=28
x=28/4
x=7
So, length of the Rectangle is {(3×7)-5}=16 inches
and width is= 7 inches
Answer:
So, length of the Rectangle is {(3×7)-5}=16 inches
and width is= 7 inches

Set up and solve an absolute value inequality to determine the range of possible ... determine if the Democratic candidate will win the election?
Step-by-step explanation:
The percentages candidate could earn falls in the range of absolute value inequality |47 - x| ≤ 4.5.
What is Absolute Value Inequality?Absolute value inequalities are kind of inequality expressions which includes the absolute value symbol in the expression.
For example : |x - 5| < 4 is an absolute value inequality.
Given that,
Percentage of American citizens going to vote for candidate B = 47%
Tolerance level = 4.5%
Suppose x be the percent of voters who will vote for candidate B.
Value of x can be,
47% + 4.5% = 51.5%
Or,
47% - 4.5% = 42.5%
The absolute value inequality for the situation is,
|47 - x| ≤ 4.5
Hence the absolute value inequality is |47 - x| ≤ 4.5.

Answers
Answer:
m<1 = 54
m<3 = 54
m<4 = 126
Step-by-step explanation:
<1: <2 and <1 are supplementary angles.
<3: <2 and <3 are supplementary angles. <1 and <3 are vertical angles.
<4: <2 and <4 are vertical angles.
Supplementary angles equal to 180 degrees.
Vertical angles are equivalent.
Let's solve for <1.
<2 + <1 = 180 --> Due to supplementary angles
126 + <1 = 180 --> Substitution
126 + <1 - 126 = 180 - 126 --> Subtracted 126 on both sides
<1 = 54 --> Simplified
Let's solve for <3.
<3 = <1 --> Due to vertical angles
<3 = 54 --> Substitution
Let's solve for <4.
<4 = <2 --> Due to vertical angles
<4 = 126 --> Substitution
Therefore, m<1 = 54, m<3 = 54, and m<4 = 126
Hope this helped! <3

1 is 54 degrees
