Answer:
x = 5
Step-by-step explanation:
5x + 30 and 2x + 45 are alternate exterior angles and are congruent, thus
5x + 30 = 2x + 45 ( subtract 2x from both sides )
3x + 30 = 45 ( subtract 30 from both sides )
3x = 15 ( divide both sides by 3 )
x = 5
42 students are going on a field trip. The students are divided into groups of four Students. How many groups of four will there be. If the remaining studentsform a smaller group, and one chaparone is assigned to every group,how many total chaparones are needed
Answer:
Step-by-step explanation:
if we have 42 students which are divided in group of 4 we will have
42/4=10 groups and 2 students left
if we would have a group out of 3 students, we will have 14 groups and 14 chaperones
a group will have 3 students and one chaperone
42 students and 14 chaperones

At the gas station, each liter of gas costs \$3$3dollar sign, 3, but there's a promotion that for every beverage you purchase you save \$0.20$0.20dollar sign, 0, point, 20 on gas.
Is your total savings on gas proportional to the number of beverages you purchase?
Yes Or No
Answer:
Yes, your total savings on gas is proportional to the number of beverages you purchase.
Step-by-step explanation:
What is a proportional relationship?
A proportional relationship, also known as direct relation, between two variables exists when the ratio between every pair of data is constant.
In this case the variables are:
number of beverage purchased
savings
Thus, as per every beverage purchase you save $ 0.20 the ratio of total savings to the number of beverage purchases is:
savings / beverages purchase = $ 0.20 / beverage
That means that you can determine the savings by multipliying the number of beverages times $ 0.20.
For proportional relationships it is easy to build a table that shows the behavior of the variables. This shows you that:
Number of beverages savings ratio
1 $ 0.20 $0.20 / 1 beverage = 0.20
2 $ 0.40 $0.40 / 2 beverages = 0.20
3 $ 0.60 $0.60 / 3 beverages = 0.20
4 $ 0.80 $0.80 / 4 beverages = 0.20

What is an equation of the line that passes through the point (-1, -3) and is perpendicular to the line x –2y = 14?
The equation of the line passing through the point ( -1,-3) will be y = -2x - 5.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
Given that the line passes through the point (-1, -3) and is perpendicular to the line x –2y = 14. the equation of the line will be calculated as:-
Make equation: y = mx + b
x = 2y + 14
2y = x - 14
y = 1/2x - 7
For a line perpendicular, the sign will be opposite and the slope will be reciprocal.
y = -2x + b
-3 = -2(-1) + b, b = -5
The equation of the line will be written as below:-
y = -2x - 5
Therefore, the equation of the line passing through the point ( -1,-3) will be y = -2x - 5.

Prisicas built a cabinet shaped like a rectangular prism .The length base is 9 inches and the width is 40 inches what is the area of the base of the cabinet in square inches
Answer:
360in²
Step-by-step explanation:
The base of the rectangular prism is a rectangle. Since we are to find the area of the base of the cabinet, then we just need to get the area of the rectangle.
Area of a rectangle = Length * Width
Given
Length = 9in
Width = 40in
Area of the base = LW
Area of the base = 9 * 40
Area of the base = 360in²
Therefore the area of the base of the cabinet in square inches is 360in²

Joe can run 12 miles in 125 minutes. How many miles can he run in 230 minutes? (solve and explain the steps)
Answer:
Joe will run 22.08 miles in 230 minutes.
Step-by-step explanation:
Given that Joe can run 12 miles in 125 minutes.so Joe running the miles in 1 minute is = 12/125 = 0.096 miles
unit rate = 0.096 miles/per minuteAs Joe runs 0.096 miles in one minute.
Thus, in 230 minutes, Joe will run = 0.096 × 230 = 22.08 miles
Therefore, Joe will run 22.08 miles in 230 minutes.

Graph: Closed circle at 11, shading to the right
======================================================
Work Shown:
[tex]x+7 \ge 18\\\\x+7-7 \ge 18-7\\\\x \ge 11[/tex]
In the second step, I subtracted 7 from both sides to undo the "plus 7".
To graph this, we place a closed or filled in circle at 11. Then we shade to the right. The endpoint x = 11 is included as part of the solution set, which is why we use a closed circle instead of an open hole.
This visually describes all values that are equal to 11 or larger than 11.

Can someone help pls?
Answer:
Step-by-step explanation:
Let the original width be x
Then the original length = x + 11
Area = x * (x + 11)
If you decrease each side by 7 you get
Area 1 = (x - 7)(x + 4)
So area - area1 =
x (x + 11) -98 = (x - 7)(x + 4) Remove the brackets
x^2 + 11x - 98 = x^2 - 7x + 4x - 28 Combine the like terms
x^2 + 11x - 98 = x^2 - 3x - 28 Add 98 to both sides
x^2 + 11x = x^2 - 3x + 70 Cancel the x^2
11x = -3x + 70 Add 3x to both sides
14x = 70 Divide by 14
x = 70 / 14
x = 5
=====================
Original conditions
Answer width = 5
Length = 16

Which value is the solution to the equation - 8 = 6-7x?
A. -7
B. - 2
c. 2
D. 5
Answer:
-8=6-7x (subtract 6 from both sides)
-14=-7x (divide each side by -7)
x=2
the answer is C
Answer:
c: 2
Step-by-step explanation:
-8 = 6 -7x, isolate the -7 by moving the 6 to the left side of the equation so it becomes -8-6 = -7x --> -14 = -7x and then divide by both sides by -7 and then you get x =2, you can plug in the number back into the equation to make sure
Bill spent less than $36 on Kitten and puppy magazines kitten magazines cost $4 each and puppy magazines cost $3 each A) write an inequality that describes the situation B) list two possible combinations of puppy and kitten magazines C) if bill bout 3 kitten magazines, how many puppy magazines can he buy?
Answer:
A) 4k + 3p < 36
B) 3 kitten magazines and 4 puppy magazines
4 kitten magazines and 6 puppy magazines
C) If bill bought 3 kitten magazines, then he buys less than 8 puppy magazines.
Step-by-step explanation:
Let:
The number of kitten magazines = k
The number of puppy magazines = p
A) Write an inequality that describes the situation
We are told:
Bill spent less than $36 on Kitten and puppy magazines kitten magazines cost $4 each and puppy magazines cost $3 each
Hence:
$4 × k + $3 × p < 36
4k + 3p < 36
B) List two possible combinations of puppy and kitten magazines
4k + 3p < 36
Bill can buy:
3 kitten magazines and 4 puppy magazines
4 kitten magazines and 6 puppy magazines
C) If bill bought 3 kitten magazines, how many puppy magazines can he buy?
Using the inequality above:
4k + 3p < 36
4k + 3p < 36
4 × 3 + 3p < 36
12 + 3p < 36
3p < 36 - 12
3p < 24
p < 24/3
p < 8
If bill bought 3 kitten magazines, then he buys less than 8 puppy magazines.
State if each triangle is a right triangle:
13 ft
5 ft
10 ft
Answer:
Step-by-step explanation:
the longest length is always the hypotenuse
Use Pythagorean theorem
a^2+b^2=c^2
5^2+10^2=c^2
c=11.18
Note: if c=13 than it is a right triangle
since 11.18 not=13
not right triangle
Answer:
It is not a right triangle
Step-by-step explanation:
a(squared) + b(squared) = c(sqaured)
a = 13, b = 5, c = 10
13 times 13 is 169
5 times 5 is 25
169 + 25 = 194
but that's not all.
10 times 10 is 100.
the problem is 169 + 25 is 194, not 100. for the triange to be a right triangle, all the numbers have to make sense. i don't know if this helps but again, it is not a right triangle.
