Answer:
The solution to the system of equations will be:
[tex]x=0,\:y=-\frac{11}{5}[/tex]
Step-by-step explanation:
Given the expression
[tex]x - 5y = 11[/tex]
[tex]3x - 5y = 11[/tex]
solving the expression
[tex]\begin{bmatrix}x-5y=11\\ 3x-5y=11\end{bmatrix}[/tex]
Multiplying x-5y = 11 by 3: 3x-15y=33
so
[tex]\begin{bmatrix}3x-15y=33\\ 3x-5y=11\end{bmatrix}[/tex]
and
[tex]3x-5y=11[/tex]
[tex]-[/tex]
[tex]\underline{3x-15y=33}[/tex]
[tex]10y=-22[/tex]
now solving 10y = -22 for y
[tex]10y=-22[/tex]
divide both sides by 10
[tex]\frac{10y}{10}=\frac{-22}{10}[/tex]
simplify
[tex]y=-\frac{11}{5}[/tex]
For 3x-5y=11 plug in y = -11/5
[tex]3x-15\left(-\frac{11}{5}\right)=33[/tex]
[tex]3x+15\cdot \frac{11}{5}=33[/tex]
[tex]3x+33=33[/tex]
Subtract 33 from both sides
[tex]3x+33-33=33-33[/tex]
Simplify
[tex]3x=0[/tex]
Divide both sides by 3
[tex]\frac{3x}{3}=\frac{0}{3}[/tex]
Simplify
[tex]x=0[/tex]
Thus, the solution to the system of equations will be:
[tex]x=0,\:y=-\frac{11}{5}[/tex]

A scale of a model of a new building was created for approval by the city. The scale of the model is 3 inches=20 feet. If the model is 5 feet tall, how tall is the actual building?
Answer:
400 feet
Step-by-step explanation:
real
1 feet = 12 inches
5 feet = 60 inches
scale
3 inches = 20 feet
60 inches=
60/3 = 20
20*20= 400
therefore 5 feet tall equall 400 feet
The actual length of the building will be 400 feet.
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The scale of the model is,
⇒ 3 inches = 20 feet
Now,
Since, The scale of the model is,
⇒ 3 inches = 20 feet
And, The model is 5 feet tall.
Since, 1 feet = 12 inches
So, 5 feet = 60 inches
Here, The scale of the model is,
⇒ 3 inches = 20 feet
So, The actual length of the building = 60 × 20/3
= 400 feet
Thus, The actual length of the building = 400 feet.

Answer:3/4
Step-by-step explanation:
The Montoya family and the Cooper family are seeing a movie together in the theater. At the concession stand, Mr. Montoya paid $20 for 3 large popcorns and 1 large drink that his family will share. Mrs. Cooper bought 3 large popcorns and 3 large drinks and paid $30. How much does each item cost?
Answer:
Both items cost $5 each
Step-by-step explanation:
Given data
let popcorn be x
and drink be y
Mr. Montoya paid $20 for 3 large popcorns and 1 large drink
so
3x+y= 20-------------1
and
Mrs. Cooper bought 3 large popcorns and 3 large drinks and paid $30
so
3x+3y= 30----------------2
solve 1 and 2 above
3x+y= 20
y= 20-3x
put y= 20-3x in eqn 2
3x+3(20-3x)= 30
3x+60-9x= 30
collect like terms
3x-9x= 30-60
-6x= -30
x= 30/6
x= $5
put x= 5 in y= 20-3x
y= 20-3*5
y= 20-15
y= $5

Joey is measuring the amount of time it takes for a frisbee to fly through the air he uses a stopwatch to time it and find that it takes 4.82 seconds if it actually takes 5.05 seconds then what is the percent error in Joey's measurement to the nearest 10th of a percent
Answer:percent error in Joey's measurement to the nearest 10th of a percent =- 4.6%
Step-by-step explanation:
Step 1
Time as recorded by the stopwatch = 4.82 seconds
Real Time it takes for a Frisbee to fly through the air =5.05 seconds
percent error = Measured value – True Value /True value x 100.
= 4.82 - 5.05 / 5.05 x 100
=-0.23/5.05
=-0.0455 x 100
=4.5544%
Rounding to nearest 10th of a percent = - 4.6%

The weights of 5 adult Chihuahuas recorded by a
veterinarian are listed below. What is the median weight
of the Chihuahuas?
2,850 g, 1,880 g, 1,530 g, 1,920 g, 2,850 g
A 2,850 g
B 1,920 g
c 2,206 g
D
1,530 g
Answer:
B. 1, 920
Step-by-step explanation:
To get the median, you order from lowest to highest.
So;
1, 530 , 1,880 , 1,920 , 2,850 , 2,850
Then you find the middle ground / the number in the middle. Since it's odd, all we have to do is look at the number directly in the middle. So the answer is B. 1, 920.

a group buys 6 hot dogs and 3 hamburgers for a total of $27.75. the hamburgers cost $1.75 more than a hot dog. what is he cost of the hamburger
Answer:
Cost of one hamburger = $4.25
Step-by-step explanation:
Let,
Cost of one hot dog = x
Cost of one hamburger = y
According to given statement;
6x + 3y = 27.75 Eqn 1
y = x + 1.75 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
6x + 3(x+1.75) = 27.75
6x + 3x + 5.25 = 27.75
9x = 27.75 - 5.25
9x = 22.50
Dividing both sides by 9
[tex]\frac{9x}{9}=\frac{22.50}{9}\\x=2.50[/tex]
Putting x=2.50 in Eqn 2
y = 2.50 + 1.75
y = 4.25
Hence,
Cost of one hamburger = $4.25

Answer:
264 boxes of crayons
Step-by-step explanation:
HI there!
To solve this, first we have to find out how many classes there are in total to make this easier.
Since they’re giving crayons to grades K-2, That means 3 grades will be getting crayons. If there’s 4 classes in each grade, multiply 4 by 3 to find the total amount of classes, which is 12.
Now to find the total amount of crayons, we multiply 12 by 22 to find the total amount of crayons bought.
They need to buy 264 boxes of crayons.

Chanasia has 11.25 gallons of paint. She wants to use 2 5 of the paint to paint her living room. How many gallons of paint will Chanasia use?
Answer: 4.5 gallons
Step-by-step explanation:
From the question, Chanasia has 11.25 gallons of paint and she wants to use 2/5 of the paint to paint her living room.
The number of gallons of paint that Chanasia will use would be calculated by multiplying the fraction by the total gallons of paint. This will be:
= 2/5 × 11.25
= 0.4 × 11.25
= 4.5 gallons
