Answer:
no solution
Step-by-step explanation:
2x + 3x - 60 = 5x
combine like terms
5x - 60 = 5x
subtract like terms (5x-5x = 0)
-60 = 0, which is untrue so there is no solution

In 1983, a microwave oven cost $78. 75. Today, a microwave oven costs $92. 66. If the CPI is 177, what is the relation of the actual price of a microwave oven to the expected price, to the nearest cent? a. The actual price is $46. 73 lower than the expected price. B. The actual price is $5. 59 lower than the expected price. C. The actual price is $13. 91 higher than the expected price. D. The actual price is $71. 35 higher than the expected price.
The actual price is $46.73 lower than the expected price.
What is the Formula for Consumer Price Index?
[tex]CPI_t=\frac{C_t}{C_0} * 100[/tex]
CPI=consumer price index in the current period
Ct= expected cost in current period
C₀ =cost in the base period
It is given that
Price in base period ie 1983 C₀= $78.75
The actual cost of the microwave oven = $92.66
Consumer Price Index= 177
So, expected price of microwave oven in the current period
Ct= CPIt * C₀ /100 = 177*78.75/100 = $139.39
Difference between the actual price and expected price = 139.39-92.66=$46.73
Therefore, The actual price is $46.73 lower than the expected price.

Maritza had to solve 5(4m-6)-10
Hi! I hope you're enjoying your day!
I can help Maritza solve this maths problem. ;)
The first step in solving this problem is using the Distributive Property and distribute 5.
How to distribute 5:
multiply 5 times 4m and -6 and simplify :)
So let's do it! :)
5(4m-6)-10
20m-20-10
Now, combine like terms:
[tex]\boxed{\boxed{\bold{20m-30}}}[/tex]
And yeah, we can't simplify this expression, because 20m and -30 are not like terms.
Hope everything is clear.
If you have any questions, please comment.

Hello there! Your question is missing some important information to solve. I will solve the equation by simplifying the expression. =)
Answer:
[tex]20m-40[/tex]
Step-by-step explanation:
Given the expression:
[tex]5(4m-6)-10[/tex]
You can simplify it as follows:
1. Apply the Distributive Property multiplying each term inside the parentheses by the number 5 outside:
[tex]=(5)~(4m)-(5)~(6)-10[/tex]
[tex]=20m-30-10[/tex]
2. Add the like terms (remember that like terms have the same variables with the same exponents):
[tex]=20m-40[/tex]
Hence, the answer is [tex]20m-40[/tex]

A game of “Doubles-Doubles” is played with two dice. Whenever a player rolls two dice and both die show the same number, the roll counts as a double. If a player rolls doubles, the player earns 5 points and gets another roll. If the player rolls doubles again, the player earns 5 more points. Whenever the player rolls the dice and does not roll a double, they lose points.
How many points should the player lose for not rolling doubles in order to make this a fair game?

Answer:
18%
Step-by-step explanation:
0.12 is 12 percent.
We also have the 0.06 percent which would just be 6 percent
We need to add up those percentages to get 18 percent, for the people surveyed that cannot swim would be 18 percent.
Our final answer is D.

Answer:
A) complementary angles
B) 58 degrees
Step-by-step explanation:
A) ∠DOE and ∠EOB are complementary angles since they both add up to 90 degrees (or right angle).
B) x + 32 = 90 (Complementary angles)
Subtract 32 to both sides
x = 90 - 32
x = 58 degrees.

Step-by-step explanation:
The angle from a stake in the ground to the top of a tree is 60 degrees. If the height of the tree is 40 feet, what is the distance from the stake to the bottom of the tree (the distance along the gound) in feet? Please explain your answer!
Answer:
23.09 ft
Step-by-step explanation:
Here we are given that the angle from stake in ground to the top of the tree is 60° and the height of the tree is 40ft . We are interested in finding out the distance from stake to the bottom of the tree . For figure refer to the attachment .
From the figure , BC = 40ft which is the perpendicular of the right angled triangle ABC . Also assume that AB = x ft , which is the base of the triangle .
Now since we have base and perpendicular , we should use the ratio of tangent as ,
[tex]\rm\longrightarrow tan\theta =\dfrac{perpendicular}{base}=\dfrac{p}{b} [/tex]
And here [tex]\theta[/tex] = 60° . On substituting the respective values , we have ;
[tex]\rm\longrightarrow tan 60^o =\dfrac{40\ ft}{x \ }\\ [/tex]
And the value of tan60° = √3 , so that ;
[tex]\rm\longrightarrow \sqrt3 =\dfrac{40\ ft}{x} [/tex]
Cross multiply ,
[tex]\rm\longrightarrow x =\dfrac{40}{\sqrt3}ft. [/tex]
The value of √3 is 1.732 approximately .
[tex]\rm\longrightarrow x =\dfrac{40}{1.732}ft. [/tex]
Simplify,
[tex]\rm\longrightarrow \underline{\underline{\red{{x =23.09\ ft }}}} [/tex]

2x + 3y = 15
x + y = 6
what is x and what is y
Answer:
[tex]{x,y}={3,3}[/tex]
Step-by-step explanation:
System of Linear Equations entered :
[tex][1] 2x + 3y = 15\\ [2] x + y = 6[/tex]
Graphic Representation of the Equations :
3y + 2x = 15 y + x = 6
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -x + 6
// Plug this in for variable y in equation [1]
[1] 2x + 3•(-x +6) = 15
[1] -x = -3
// Solve equation [1] for the variable x
[1] x = 3
// By now we know this much :
x = 3
y = -x+6
// Use the x value to solve for y
y = -(3)+6 = 3
Solution :
{x,y} = {3,3}
Answer:
[tex](3,3)[/tex]
Step-by-step explanation:
[tex]\begin{bmatrix}2x+3y=15\\ x+y=6\end{bmatrix}[/tex]
[tex]\mathrm{Substitute\:}x=\frac{15-3y}{2}[/tex]
[tex]\begin{bmatrix}\frac{15-3y}{2}+y=6\end{bmatrix}[/tex]
[tex]\begin{bmatrix}\frac{15-y}{2}=6\end{bmatrix}[/tex]
[tex]y=3[/tex]
[tex]\mathrm{For\:}x=\frac{15-3y}{2}[/tex]
[tex]\mathrm{Substitute\:}y=3[/tex]
[tex]x=\frac{15-3\cdot \:3}{2}[/tex]

A toy maker used 36 batteries for his 9 new toy cars. The toy maker uses the same amount of batteries for each toy car. Which table shows the relationship between the amount of batteries and the amount of toy cars? = 25x
The table that shows the proportional relationship between the number of batteries and the number of toy cars is as follows:
x = 12, y = 3x = 24, y = 6x = 48, y = 12 Proportional relationshipproportional relationships are relationships between two variables where their ratios are equivalent.
Therefore, If we establish the relationship between the number of batteries and the number of car toys, we can draw the table.
Therefore,
let
y = kx
where
y = number of toys
x = number of batteries
Therefore,
9 = 36k
k = 9 / 36
k = 1 / 4
y = 1 / 4 x
Therefore,
x = 12, y = 12 / 4 = 3x = 24, y = 24 / 4 = 6x = 48, y = 48 / 4 = 12The question wants to draw a table for the proportional relationship between x(number of batteries) and y(number of toy cars).

Answer:
(x + 10)(x - 10)
Step-by-step explanation:
x² - 100 = x²- 10²
x² - 100 is the difference of two squares.
The factorization of the difference of two squares is
a² - b² = (a + b)(a - b)
x² - 100 = (x + 10)(x - 10)
