Step-by-step explanation:
A linear pair of angles is formed when two lines intersect.
Two angles are linear if they are adjacent angles formed by two intersecting lines.
Since the measure of a straight angle is 180°, a linear pair of angles must add up to 180°.
1. Two angles that add up to 180° are called supplementary.
2. The image shows a linear pair of angles. On the left side, the angle measures 2x, on the right side, the angle measures x+30. Since the sum is 180°:
2x + x + 30 = 180
Simplifying:
3x + 30 = 180
Subtracting 30:
3x = 180 - 30 = 150
Dividing by 3=
x = 150 / 3 = 50
x = 50°
3. The angle on the left is 2x = 100°
Angle measure on the left = 100°
4. The angle on the right is x+30 = 80°
Angle measure on the right = 80°

x = 0.59 to the nearest hundredth
Step-by-step explanation:
Look at the attached figure
The equation is 2x + [tex]e^{x}[/tex] = 3The red curve represents the left side of the equationThe blue line represents the right side of the equationThe solution of the equation is the point of intersection of the two graphs∵ There are 5 small squares between every 2 numbers on the x-axis
∴ Each square represents 0.2
∵ There are 5 small squares between every 2 numbers on the y-axis
∴ Each square represents 0.2
∵ The point of intersection between the 2 graphs is nearest to
the 3rd small square after the zero on the x-axis
∵ 0.2 × 3 = 0.6
∴ The x-coordinate of the point is approximately located at 0.59
∴ x = 0.59 to the nearest hundredth

How many integers between 27 and 53 have a remainder of 4 divided by 6
Answer:
There are 4 integers between 27 and 53 that have a remainder of 4 divided by 6.
Step-by-step explanation:
At first we need to find which integers between 27 and 53 are divisible by 6, which are, respectively:
[tex]A =\{30, 36, 42, 48\}[/tex]
All integers that have a remainder of 4 divided by 6 are found by summing 4 to each element of A, that is:
[tex]A' = \{34,40,46, 52\}[/tex]
There are 4 integers between 27 and 53 that have a remainder of 4 divided by 6.

Travis made a business trip of
195.5 miles. He averaged
53 mph for the first part of the trip and
58 mph for the second part. If the trip took
3.5 hours, how long did he travel at each rate?
Answer:
At 53 mph, he traveled for 1.5 hours
At 58 mph, he traveled for 2 hours
Step-by-step explanation:
Mathematically;
distance = speed * time
let the time for the first part of the trip be x hours and the second part be y hours
Total hours is 3.5
So therefore;
x + y = 3.5 ••••••••(i)
Now let’s work with the rate
53 mph for x hours = 53 * x = 53x miles
58 mph for y hours = 58 * y = 58y miles
Adding both;
53x + 58y = 195.5 miles ••••••••(ii)
We have two equations to solve simultaneously
From i, x = 3.5 - y
insert into ii
53(3.5-y) + 58y = 195.5
185.5 - 53y + 58y = 195.5
5y = 195.5-185.5
5y = 10
y = 10/5
y = 2 hours
x = 3.5 - y
x = 3.5 - 2
x = 1.5 hours

Seven out of ten people say they will vote for Mrs. Meekus . If 5,500 people vote,how many are likely to vote for Mrs.Meekus
Answer:
3,850 people are likely to vote for Mrs. Meekus.
Step-by-step explanation:
Given that Mrs. Meekus has a voting intention of 7 out of 10, that is, 70%, in the event that 5,500 people are going to vote in the elections, the voting intention for this candidate would be obtained through the following calculation:
5,500 x 0.70 = X
3,850 = X
Thus, if said voting intention is reproduced, Mrs. Meekus would be voted by 3,850 voters.

what is five less than a number is greater than twenty
Answer:
X = -5
Step-by-step explanation:
"Five less than a number is greater than twenty" represents the inequality (x - 5) > 20
Let a number is 'x'.
Now we will construct the inequality for the given statement.
"Five less than a number" means (x - 5)
And "five less than a number is greater than twenty" will be,
(x - 5) > 20
To simplify this inequality,
Add 5 on both the sides of the inequality,
(x - 5) + 5 > 20 + 5
x > 25
Therefore, five less than a number is greater than twenty is an inequality, (x - 5) > 20

20. John Navarro is a salesperson in the appliance department at Morris
Appliance, Inc. He is guaranteed a minimum salary of $185 per week, or
5.5 percent of his total sales—whichever is greater. What is his gross pay
for a week in which his total sales were $3,422?
Answer:
$373.21Step-by-step explanation:
Step one:
weekly pay = $185
commission= 5.5% of sales= 0.055
let the sale be x
and his gross pay be represented by y
hence the expression for the total/gross pay is
y=0.055x+185
Step two:
Required is the gross pay y for x=3422
substituting we have
y=0.055*3422+185
y=188.21+185
y=373.21
Hence for a sale of $3,422 made his gross pay is $373.21

The owner of a grocery store wants to mix two kinds of candy together to make 15 lb that he can sell for $5.00 per lb. He wants to use chocolate candies that he sells for $7.00 per lb and sugar candies that he sells for $2.00 per lb. How many pounds of each should the owner use?
_ pounds of chocolate candies
_ pounds of sugar candies
=OWO=
Answer: 9 pounds of chocolate and 6 pounds of sugar candies
Let's define the variables:
C = pounds of chocolate candies used.
S = pounds of sugar candies used.
We know that he wants to make a total of 15lb, then:
C + S = 15
We also want that the price per pound to be equal to 5$.
This means that the price of the 15 pounds will be the same as the price of the un-mixed candies.
C*$7.00 + $2.00*S = $5.00*15
Then we have a system of equations:
C + S = 15
C*$7.00 + $2.00*S = $5.00*15
To solve this system, we need to start by isolating one of the variables, i will isolate C in the first equation:
C = 15 - S
now we can replace that in the other equation:
(15 - S)*$7.00 + $2.00*S = $5.00*15
Now we can solve this for S.
$105 - $5.00*S = $75
$105 - $75 = $5.00*S
$30 = $5.00*S
$30/$5 = S = 6
Then there are 6 pounds of sugar candy, and we can use the equation:
C + S = 15
C + 6 = 15
C = 15 - 6 = 9
There are 9 pounds of chocolate candy in the mix.
Step-by-step explanation:
By writing and solving a system of equations, we will see that the owner must use 6 lb of the chocolate candies and 9 lb of the sugar candies.
Let's define two variables:
x = pounds of chocolate candies usedy = pounds of sugar candies used.Then, using the given information, we will have that:
x + y = 15
x*$7.00 + y*$2.00 = $5.00*15
If we isolate x in the first equation we get:
x = 15 - y
Now we can replace that in the second equation to get:
(15 - y)*$7.00 + y*$2.00 = $75
$105 - y*$5.00 = $75
$105 - $75 = y*$5.00
$30 = y*$5.00
$30/$5 = y = 6
So the owner must use 6 pounds of the chocolate candies, and the other 9 pounds of the sugar candies.

A. Collinear
B. Congruent
C. Midpoint
D.equal
Answer:
A.
Explanation:
Collinear
The required term is "collinear" which best describes three points that all lie in a straight line. which is the correct answer would be an option (A).
What are the collinear points?Collinear points are locations along a straight line that are represented by a collinear. They are always collinear since a straight line may be traced continuously between any two places. A collinear connection can exist between three or more points, but it is not required. The word required is "collinear," which best depicts three locations that are all in a straight line.
Therefore, the required term is "collinear" which best describes three points that all lie in a straight line.
Hence, the correct answer would be option (A).
