Michael and Landon work at a dry cleaners ironing shirts. Michael can iron 40 shirts per hour, and Landon can iron 20 shirts per hour. Michael and Landon worked a combined 14 hours and ironed 360 shirts. Graphically solve a system of equations in order to determine the number of hours Michael worked, ,x, and the number hours Landon worked, y.
I need two equations in y=mx+b form pls
Answer:
Michael worked 4 hours and Landon worked 10 hours.
Step-by-step explanation:
Michael can iron 40 shirts each hour, so in xx hours he can iron 40x40x shirts. Landon can iron 20 shirts each hour, so in yy hours he can iron 20y20y shirts. The total number of shirts ironed 40x+20y equals 360:
40x+20y=360
40x+20y=360
Since Michael and Landon worked a combined 14 hours, we know x+yx+y must equal 14.
x+y=14
Write System of Equations:
40x+20y= 360
x+y=14
Solve for y in each equation:
40x+20y = 360 x+y = 14 20y = -40x+360
[tex]\frac{-20y}{20}[/tex] =[tex]\frac{-40x+360}{20}[/tex]
y = -2x+18

Jason has been smoking cigarettes since he was 13 years old. He has smoked an a age of one pack of cigarettes a day since he started smoking. A single pack contains 20 individuals cigarettes. What is the number of cigarettes he will smoke by the time he's 15, 19, 25, and 50? How many packs will he have smoked by then?
Answer:
No of cigarettes
15 years of age = 14600 cigarettes
19 years of age = 43800 cigarettes
25 years of age = 87600 cigarettes
50 years of age = 270100 cigarettes
No of packs
15 years of age = 730 packs
19 years of age = 2190 packs
25 years of age = 4380 packs
50 years of age = 13505 packs
Step-by-step explanation:
Jason started smoking when he turned 13 years of age.
Average smoking per day = 1 pack = 20 cigarettes
No of Cigarettes consumed
When he turned 15 yearsNo of days = 730 days
No of cigarettes = 730 * 20 = 14600 cigarettes
When he turns 19No of days = 6*365 = 2190 days
No of cigarettes = 2190*20 = 43800 cigarettes
When he turns 25No of days = 12*365 = 4380 days
No of cigarettes = 4380*20 = 87600 cigarettes
When he turns 50No of days = 37*365 = 13505
No of cigarettes = 13505*20 = 270100 cigarettes
No of packs
15 years of age = 14600/20 = 730 packs
19 years of age = 2190 packs
25 years of age = 4380 packs
50 years of age = 13505 packs

Two health clubs offer different pricing plans for their members. Both health clubs charge a one-time sign-up fee and a monthly membership fee. The graph below represents what Health Club A charges.
The table below represents what Health Club B charges.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete but I would show how this charges can be represented by an equation.
For health club A:
The graph (x, y) passes through the points (2, $136) and (4, $242). Let x represent the total months and y represent the total charges. The equation is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-136=\frac{242-136}{4-2}(x-2)\\\\y-136=53(x-2)\\\\y-136=53x-106\\\\y=53x+30[/tex]
For health club B:
The table (x, y) has the points (4, 173) and (6, 23y). Let x represent the total months and y represent the total costs. The equation is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-173=\frac{237-173}{6-4}(x-4)\\\\y-173=32(x-4)\\\\y-173=32x-128\\\\y=32x+45[/tex]

I won't be able to graph for you because I am currently on phone but I will tell how to graph an Inequality in coordinate plane.
[tex] {x}^{2} + 4 < 0[/tex]
We don't need to solve the Inequality. The graph will do.
We draw the parabola with the vertex at (0,4) Basically plot point (0,4) then draw parabola.
Because it is < sign, thus the shade/region will be below the graph.
So the shade will be outside of the curve and not inside.

The turkey Damian's dad bought at the store weighed 23 pounds after it was cooked. When his aunt cut all the meat off the bone, the meat weighed 17 pounds. Damian says that the meat of the cooked turkey was 74% of the weight of the turkey. Do you agree with Damian?
Answer:
YES.
Step-by-step explanation:
Given:
Weight of turkey with bone = 23 pound
Weight of turkey without bone = 17 pound
Computation:
Weight of turkey without bone percent = [17/23]100
Weight of turkey without bone percent = 73.913 %
Weight of turkey without bone percent = 74% (Approx)
So,

Stephanie's school is selling tickets to a play. On the first day of ticket sales the school sold 4 adult tickets and 10 student tickets for a total of $150. The school took in $105 on the second day by selling 1 adult ticket and 10 student tickets. What is the price each of one adult ticket and one student ticket?
Answer:
The price of
1 adult ticket = $15
1 student ticket = $9
Step-by-step explanation:
Let
The price of adult tickets be represented by a
The price of student tickets be represented by s
Therefore:
On the first day of ticket sales the school sold 4 adult tickets and 10 student tickets for a total of $150.
4a + 10s = $150.... Equation 1
The school took in $105 on the second day by selling 1 adult ticket and 10 student tickets.
a + 10s = $105.... Equation 2
a = $105 - 10s
Therefore, we substitute : $105 - 10s = a in Equation 1
4a + 10s = $150.... Equation 1
4($105 - 10s) + 10s = $150
$420 - 40s + 10s = $150
Collect like terms
- 40s + 10s = $150 - $420
-30s = -$270
Divide both sides by -30
-30s/-30 = -$270/-30
s = $9
We find a
a = $105 - 10s
a = $105 - 10($9)
a = $105 - $90
a = $15
Therefore, the price of
1 adult ticket = $15
1 student ticket = $9

How much grape juice would you need to mix with 154 quarts of sparkling water?
The amount of grape juice need to mix with 15 / 4 quarts of sparkling water is , 15/8 quarts.
What is Quart measurement ?The quart is a measurement which is use to find the capacity of liquid. Or we can say Quart is a unit of liquid volume which is measured in gallon. There are different measurements into which we can convert the unit such as ounces and liters.
Mathematically, we can write :
1 quart = 32 fluid ounces
or
1 quart = 0.94 US liters = 4 cups (approx.)
According to question,
[tex]1\frac{1}{2}[/tex] quarts of water = 3/2 quarts of water = 3/4 quarts of grape
let, 15 /4 quarts of sparkling water = x
now, solving the equation
x = ( 3/4 × 15/4 ) ÷ 3/2
x= 3/4 × 15/4 ×2/3
x =15/8
Thus, The grape juice needed is , 15/8 quarts.

On July 4, 2017, the United States of America had a population of 325.7 million people. The total land area of the United States is 3,535,932 square miles. What was the population density of the United States on July 4, 2017? Round to the nearest tenth.
The population density in the United States is D = 92.1 people/mi^2
How to get the population density?
To get the population density, we need to take the quotient between the total number of people and the area.
In this case, we know that the total population is 325.7 million, and the area of the United States is 3,535,932 mi^2
Then the population density:
D = (325.7 million)/( 3,535,932 mi^2) = 9.21*10⁻⁵ million/mi^2
And we know that 1 million = 1,000,000 = 1*10⁶
Then:
9.21*10⁻⁵ million/mi^2 = 9.21*10¹ people/mi^2 = 92.1 people/mi^2
This means that in each square mile in the United States, there are around 92.1 people.

According to the graph shows, the answer should be A, which is one student has lived in 7 states.
On a coordinate plane, an absolute value graph has a vertex at (1, 3). Which equation represents the function graphed on the coordinate plane? g(x) = |x + 1| + 3 g(x) = |x + 3| – 1 g(x) = |x – 1| + 3 g(x) = |x + 3| + 1
Answer: g(x)= |x-1| + 3
Step-by-step explanation: the |x-1| means you need to move the vertex to the right by one and the +3 means you must move the vertex up by three
The equation that represents the function on a coordinate plane is [tex]g(x) =|x - 1| + 3[/tex]
The vertex is given as:
[tex](h,k) = (1,3)[/tex]
An absolute function is represented as:
[tex]y = a|x - h| + k[/tex]
Substitute 1 for h, and 3 for k
[tex]y = a|x - 1| + 3[/tex]
Assume that the value of (a) is 1
[tex]y = 1 \times |x - 1| + 3[/tex]
So, we have:
[tex]y =|x - 1| + 3[/tex]
Represent as a function
[tex]g(x) =|x - 1| + 3[/tex]
Hence, the equation that represents the function on a coordinate plane is [tex]g(x) =|x - 1| + 3[/tex]
