Answer:
Step-by-step explanation:
let the number of children be x
and the number of adults be y
so
7x+12y=236-----1
and
14x+7y=217------2
equating both 1 and 2 we have
7x+12y=236-----1
14x+7y=217------2
multiply 1 by 2
subtract 2 from 1 we have
14x+24y=472-----3
- 14x+7y=217------2
0x+17y=255
17y=255
y=255/17
y=15
put y=15 in eqn 1 we have
7x+12y=236-----1
7x+12*15=236-----1
7x+180=236-----1
7x=236-180
7x=236-180
x=56/7
x=8
therefore a child will cost $8 and adult will cost $15

beacause 8 times 3 is 24 and 12 times 2 is 24
Answer:
A
Step-by-step explanation:
I cant find the words to explain. They both meet at 24. 8 x 3 = 24 and 12 x 2 = 24. So 3 packages of 8 and 2 packages of 12.
46. Hannah walks dogs for four different families. She charges each family the same
amount of money per hour. The numbers of hours she worked last week walking
dogs for each of the families are shown.
14 hours, 2 hours, 13 hours
, 3 hours
Hannah earned $93 for the hours she worked last week walking dogs.
• Calculate the amount of money Hannah earns per hour for walking dogs
• Write an equation that can be used to determine the amount of money, m, in
dollars, Hannah earns when she works h hours walking dogs.
• Show your work or explain your answer.
Answer:
Hannah earns $2.9 per hour for walking dogsThe equation is m = $2.9hStep-by-step explanation:
From the question,
Hannah walks dogs for four different families and charges them the same amount of money per hour. Also, The numbers of hours she worked last week for each of the families are 14hours, 2 hours, 13 hours, and 3 hours.Hence, she worked for a total of (14 + 2 + 13 + 3) hours.
(14 + 2 + 13 + 3) hours = 32 hours
Hence, she worked for a total of 32 hours last week.
Also, she earned $93 for the hours she worked last weekTo calculate the amount of money Hannah earns per hour for walking dogs, that will be
$93 ÷ 32 hours = $2.9/hour
Hence, Hannah earns $2.9 per hour for walking dogs
For the equation that can be used to determine the amount of money, m, Hannah earns when she works h hours walking dogs,
If she works h hours for working dogs, then she will earn
$2.9 × h = $2.9h
Hence,
m = $2.9h
Where m is the amount of money Hannah earns in dollars
and h is the number of hours she spends walking dogs.
What is the difference of the fractions? Use the number line and equivalent fractions to help find the answer. Negative 2 and one-half minus (negative 1 and three-fourths) A number line going from negative 3 to 0 in increments of One-fourth. a \large -4\frac{1}{4} b \large -\frac{3}{4} c -4 d \large -\frac{1}{2}
Answer:
B)[tex]\frac{-3}{4}[/tex]
Step-by-step explanation:
We are supposed to find the difference of the fractions
a) [tex]-2\frac{1}{2}-(-1\frac{3}{4})[/tex]
[tex]=\frac{-5}{2}+\frac{7}{4}[/tex]
Using equivalent fraction
[tex]-\frac{5}{2} \times \frac{2}{2} = \frac{-10}{4}\\\Rightarrow \frac{-10}{4}+\frac{7}{4}[/tex]
Plot both fractions on number lines
So Using number line
[tex]\frac{-10}{4}+\frac{7}{4}=\frac{-5}{2}+\frac{7}{4}=\frac{-3}{4}[/tex]
So, Option B is true
Find the slope passing through the given points using the slope formula

4/11
9/2
2/9
11/4
Writewrite an equation of the line passing through the point p (-2, 6) that is parallel to the line x= -5.
Answer:
Since the slope of the line x= - 5 is infinite
The line will be parallel to y axis.
And the line passes through - 2, so the equation will become x= -2

x + 9 – 0.8x = 5.2x + 17 – 8 pls help
Answer:
X = 6x
Step-by-step explanation:
Simplifying
X + 9 + -0.8x = 5.2x + 17 + -8
Reorder the terms:
9 + X + -0.8x = 5.2x + 17 + -8
Reorder the terms:
9 + X + -0.8x = 17 + -8 + 5.2x
Combine like terms: 17 + -8 = 9
9 + X + -0.8x = 9 + 5.2x
Add '-9' to each side of the equation.
9 + X + -9 + -0.8x = 9 + -9 + 5.2x
Reorder the terms:
9 + -9 + X + -0.8x = 9 + -9 + 5.2x
Combine like terms: 9 + -9 = 0
0 + X + -0.8x = 9 + -9 + 5.2x
X + -0.8x = 9 + -9 + 5.2x
Combine like terms: 9 + -9 = 0
X + -0.8x = 0 + 5.2x
X + -0.8x = 5.2x
Solving
X + -0.8x = 5.2x
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '0.8x' to each side of the equation.
X + -0.8x + 0.8x = 5.2x + 0.8x
Combine like terms: -0.8x + 0.8x = 0.0
X + 0.0 = 5.2x + 0.8x
X = 5.2x + 0.8x
Combine like terms: 5.2x + 0.8x = 6x
X = 6x
Simplifying
X = 6x
Answer:
X=6x
Step-by-step explanation:
A contractor bought 6.4 ft2 of sheet metal. He has used 2.1 ft2 so far and has $77.40 worth of
sheet metal remaining. The equation 6.4x - 2.1x = 77.4 represents how much sheet metal is
remaining and the cost of the remaining amount. How much does sheet metal cost per square
foot?
Answer:
$18
Step-by-step explanation:
Given:
6.4x - 2.1x = 77.4
Where,
x = cost of sheet metal per square foot
How much does sheet metal cost per square foot?
6.4x - 2.1x = 77.4
4.3x = 77.4
Divide both sides by 4.3
x = 77.4 / 4.3
= 18
x = $18
Sheet metal per square foot cost $18

Rachel tutors English. for each hour that she tutors, she earns 50 dollars. Let E be her earnings (in dollars) after tutoring for H hours. Write an equation relating E to H. Then use this equation to find Rachel’s earnings after tutoring for 19 hours
Answer:
a. E = 50 H b. 950 dollars
Step-by-step explanation:
a. Since Rachel tutors English for 50 dollars for each hours, her rate is 50 dollar per hour. If she tutors for time, H hours, Her earning E = rate × time = 50 × H
E = 50H.
b. If Rachel's earnings after tutoring for 19 hours is gotten by substituting H = 19 into the equation for the earnings, E.
So, E = 50H
E = 50 × 19
E = 950 dollars.
So, Rachel's earnings after 19 hours is 950 dollars.
Every month, Rachel gets a basic salary of $4000. She also gets a bonus of $200 for each policy she sells and a bonus of $50 for each client's compliant she resolves. Write an expression for her total salary for a month if she sells n policies an resolves x complaints
Answer:
4000+200n+50x=
Step-by-step explanation:
the amount of policies or complaints times the money she would get.
Answer:
4000+200n+50x
Step-by-step explanation:
since we dont know how many policies she will sell or how many complaints she will resolve, they need to be variables. so if
N= amount of policies sold
x= complaints resolved
then it would be 4000+200n+50x

The highest point on Earth is Mount Everest with a height of 8,848 meters. The lowest point on Earth is the Mariana Trench, with a height of -11,034 meters. A height of 0 corresponds to sea level (the height of the world's oceans). What is the vertical distance between Mount Everest and Mariana Trench? Write the expression then solve it.
Answer:
The vertical distance between Mount Everest and Mariana Trench will be 19,882 ft
Step-by-step explanation:
Here, we want to get the vertical distance between the highest point on the Earth and the lowest point on the Earth
To find the vertical distance, we simply subtract the height of the lowest point from the height of the highest point
Mathematically, that would be;
8848 - ( 11, 034) = 19,882 ft
Find the missing endpoint if one endpoint is at (5.-7) and the midpoint is at (15.1).
Answer:
(25, 9)Step-by-step explanation:
Given Point (5, -7) and midpoint (15, 1)To findMissing endpointSolutionMidpoint formula:
x = (x1 + x2)/2, y = (y1 + y2)/2Substituting values:
15 = (5 + x2)/2 ⇒ 5 + x2 = 30 ⇒ x2 = 30 -5 ⇒ x2 = 251 = (-7 + y2)/2 ⇒ -7 + y2 = 2 ⇒ y2 = 2 - (-7) ⇒ y2 = 9Missing endpoint is:
