2x + y = -2
x + y = 5
Answer:
x= -7, y= 12
Step-by-step explanation:
To find the value of x and y, first label the 2 equations.
2x +y= -2 -----(1)
x +y= 5 -----(2)
(1) -(2):
2x +y -(x +y)= -2 -5
2x +y -x -y= -7 (expand bracket)
x= -7
subst. x= -7 into (2):
-7 +y= 5
y= 5 +7 (+7 on both sides)
y= 12

Dave is hanging dry wall in a house with square rooms. He completes on average 2/ 3 of a wall in 1/2 of an hour. What is Dave's rate of completion expressed in walls per hour?
A. 1 /3
B. 3 /4
C. 1 1/6
D. 1 1/3
Dave's rate of completion is 4/3 walls per hour and this can be determined by using the concept of unit rate.
Given :
Dave is hanging dry wall in a house with square rooms. He completes on average 2/ 3 of a wall in 1/2 of an hour.The following steps can be used in order to determine Dave's rate of completion:
Step 1 - The concept of unit rate can be used in order to determine Dave's rate of completion.
Step 2 - According to the given data, Dave completes on average 2/3 of a wall in 1/2 of an hour.
Step 3 - Now, let Dave's rate of completion be 'x'.
Step 4 - So, the value of 'x' can be calculated as:
[tex]x = \dfrac{\dfrac{2}{3}}{\dfrac{1}{2}}[/tex]
Step 5 - Simplify the above expression.
[tex]x = \dfrac{2}{3}\times\dfrac{2}{1}[/tex]
[tex]\rm x = \dfrac{4}{3}\;walls \;per \;hour[/tex]
Therefore, Dave's rate of completion is 4/3 walls per hour.

Mai wants to make a scale drawing of her kitchen. Her kitchen is a rectangle with length 6 m and width 2 m. She decides on a scale of 1 to 40.
Draw and label the dimensions of a scale drawing of Mai’s kitchen, using a scale of 1 to 40. HEEEEEEEELPPPP
Answer:
Length of scale = 15 cm
Width of scale = 5 cm
Step-by-step explanation:
Dimensions of the kitchen of Mai are given as:
Length of kitchen = 6 m
Width of kitchen = 2 m
Scale to be used = 1 to 40
To find:
The drawing with labeling and dimensions of the scale drawing.
Solution:
First of all, let us understand about the concept of scaling.
Scaling is a method to represent big structures on paper.
For this purpose, we decide a scaling factor and draw the big structures on paper by scaling down (making it small) by using a scaling factor.
Here, the scale factor used is 1 to 40.
i.e. 1 unit on scale is equivalent to 40 units on the actual kitchen.
40 units of kitchen = 1 unit of scale
1 unit of kitchen = [tex]\frac{1}{40}[/tex] units of scale
6 m of kitchen = [tex]\frac{1}{40}\times 6\ m = \frac{600}{40}\ cm = 15\ cm[/tex]
Length of scale = 15 cm
40 units of kitchen = 1 unit of scale
1 unit of kitchen = [tex]\frac{1}{40}[/tex] units of scale
2 m of kitchen = [tex]\frac{1}{40}\times 2\ m = \frac{200}{40}\ cm = 5\ cm[/tex]
Width of scale = 5 cm
Please refer to the attached image as well for representation of given scale.

x = 20
Step-by-step explanation:
Since the two angles are vertical, they are equal.
That means

Solve for x using the vertical angles below:
(2 + 3x)
62
Answer:
20
Step-by-step explanation:
Solving for x using the vertical angles we get , the value of x is: x = 20.
Here, we have,
from the given figure we get,
angle (2 + 3x) and angle62 are opposite angles.
we know that,
When two lines intersect each other, then the opposite angles, formed due to intersection are called vertical angles or vertically opposite angles. A pair of vertically opposite angles are always equal to each other.
so, we have,
angle (2 + 3x) = angle62
(2 + 3x) = 62
or, 3x = 60
or, x = 20
Hence, Solving for x using the vertical angles we get , the value of x is: x = 20.

Deanna and Lulu are playing games at the arcade. Deanna starts with $15, and the machine she is playing costs $0.75 per game. Lulu starts with $13, and her machine costs $0.50 per game. After how many games will the two friends have the same amount of money remaining? Write and solve an equation. Let g represent the number of games. Show your work.
i really need an answer!
Answer:
8
Step-by-step explanation:
15 - .75g = 13 - .50g
2 = .25g
8 = g
If Deanna starts with $15, and the machine she is playing costs $0.75 per game. Lulu starts with $13, and her machine costs $0.50 per game.Then after 8 games will the two friends have the same amount of money remaining
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Let g represents game
Deanna starts with $15, and the machine she is playing costs $0.75 per game
So the equation will be
15 -0.75g
Lulu starts with $13, and her machine costs $0.50 per game.
The equation for Lulu will be
13 - 0.50g
Now let us equations of both Deanna and Lulu
15 -0.75g =13 - 0.50g
15-13=0.75g-0.50g
2 = 0.25g
Divide both sides by 0.25
8 = g
Hence after 8 games the two friends have the same amount of money remaining

Answer: 6) 15 1/10
Step-by-step explanation:
Add the whole numbers and then find a common number for the bottom fraction. So that'd be ten. To get to ten from 2 you'd multiply by five then multiply the top number by five too. That gets you 5/10 and do the same for the other fraction. Get the bottom number to ten then whatever you multiply by do the same to the top. After doing that putting the fractions together which gets you 11/10. That'd make 1 1/10 so that makes it 15 instead of 14 whole

A band is playing at an auditorium with floor seats and balcony seats. The band wants to sell the floor
tickets for $15 each and balcony tickets for $12 each. They want to make at least $3,000 in ticket sales.
1. How much money will they collect for selling x floor tickets?
2. How much money will they collect for selling y balcony tickets?
Answer:
We know that x is the number of floor tickets they sell, and each one costs $15, then the amount of money they will get by those sells is x times $15, this is:
x*$15.
And y is the number of balcony tickets they sold, each one of these costs $12, then the total amount of money made in those tickets is:
y*$12.
Then the total amount of money that the band made is:
x*$15 + y*$12
And they want to make, at least, $3,000, then we will have the inequality:
x*$15 + y*$12 ≥ $3000
That can´t really be solved, because we have two variables and only one inequality, but this represents the given situation.

Answer:
Option C. 154 cm²
Step-by-step explanation:
From the question given above, the following data were obtained:
Pi (π) = 22/7
Diameter (d) = 14 cm
Area (A) =?
Next, we shall determine the radius of the circle. This can be obtained as follow:
Diameter (d) = 14 cm
Radius (r) =?
r = d/2
r = 14/2
r = 7 cm
Finally, we shall determine the area of the circle as illustrated below:
Pi (π) = 22/7
Radius (r) = 7 cm
Area (A) =?
The area of a circle can be obtained by using the following formula:
A = πr²
A = 22/7 × 7²
A = 22/7 × 7 × 7
A = 22 × 7
A = 154 cm²
Thus, the area of the circle is 154 cm²
Answer:
area of circle=π(14/2)²=22/7 ×7²=22×7=154cm²
