The cost of 2 tables and 3 chairs is $705. If the table costs $40 more than the chair, how much does a table cost?
Answer:
Step-by-step explanation:
2 tables and 3 chairs is $705
Let t stand for table and c stand for chair
3c + 2t = 705
We are told that the table costs $40 more than the chair, so t = c + 40
Now we can insert this into the equation
3c + 2(c + 40) = 705
The next step is to distribute the 2
3c + 2c + 80 = 705
Then combine like terms
5c + 80 = 705
To get the variable by itself, you have to subtract the 80 from both sides.
5c = 705 - 80
5c = 625
This means that 5 chairs costs $625.
Divided both sides by 5 to isolate the variable
c = 625/5
c = 125
Great, now you know the cost of one chair, $125!
The question is asking how much a table costs, and we know that a table costs $40 more than a chair.
A table costs $125 + $40
A table costs $165
Hope this helps! =)

A store sells a 3 -pound bag of oranges for $3.60 and a 5 -pound bag of oranges for $5.25 . What is the difference between the price per pound for the 3 -pound bag of oranges and the price per pound for the 5 -pound bag of oranges
Answer:
The price of 3 pounds would be $1.20 per pound and the price of 5 pounds would be $1.05 per pound
So, Five pound would cost 15 cents less than the 3 pounds
Step-by-step explanation:
Divide the price by the pounds

Answer:
1/1 = 1
Step-by-step explanation:
Use rise/run.
The x value increases by 1 in the same amount of time that the y value increases by 1. This gives you the slope 1/1 (y increase/x increase).
1/1 can then be converted to 1.

Point M(-6,8) is dilated from the origin with a scale factor of 1/2. What is the coordinate of M'? *
Point M(-6,8) is dilated from the origin with a scale factor of 1/2, hence the new point is M'(-3, 4)
Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, dilation and translation.
If a point A(x, y) is dilated by a factor k, the new point is A'(kx, ky).
Given Point M(-6,8) is dilated from the origin with a scale factor of 1/2, hence the new point is at:
M'(-3, 4)

I know the answer is 11, but how? When I did it, I got -29 and I don’t know how to get 11. Could someone explain step by step on how to get the correct answer?
5(-2)² - 9
First, solve the one in the bracket which is -2 × -2 which gives us =4

The sum of two numbers is 70, and their difference 30. Find the two numbers using the process of substitution. Let the first umber = x and the second number = y.
Answer:
x = 50, y = 20.
Step-by-step explanation:
x + y = 70
x - y = 30
From the second equation x = 30 + y, so substituting this in the first equation:
30 + y + y = 70
2y = 70 - 30 = 40
y = 20
and x - 20 = 30
so x = 50.
Answer:
20 , 50
Step-by-step explanation:
The sum of two numbers is 70 ⇒ x + y = 70 -------------(I)
x = 70 - y
Their difference 30 ⇒ x - y = 30 ----------(II)
Substitute x = 70 - y in equation (II)
70 - y - y = 30
Combine like terms
70 - 2y = 30
-2y = 30 - 70
-2y = -40
Divide both sides by (-2)
y = -40/-2
x = 20
Substitute the value of x in (I)
20 + y = 70
y = 70 - 20
y = 50
