A. 5= -2(x - 1)
B. 5 = -22 + 2
1) How can we get Equation B from Equation A?
Choose 1 answer:
Answer:
part 2 is A: yes
Step-by-step explanation:
Option B is correct.
We have the two following equations -
A. 5 = -2(x - 1)
B. 5 = -2x + 2
We have to find out how can we get Equation B from Equation A?
State the distributive property.According to the distributive property -
a(y + z) = (a x y) + (a x z)
According to the question -
We have -
-5 = -2(x - 1)
Using the distributive property, we can rewrite the right hand side as follows -
-5 = -2(x - 1) = ( -2x ) + (2) = -2x + 2
Hence, option B is correct.

A map is created on the coordinate plan, lori's house is located at ( -3, 7) and Andreas house is located at (-3,-4). Each unit on the map represents 0.2 mile.
Answer: 2.2 miles.
Step-by-step explanation:
I guess that we want to find the distance between Lori's and Andrea's houses.
First, we have the locations:
L = (-3, 7)
A = (-3. -4)
To find the distance (in units) between two coordinate points (a1, a2) and (b1 b2) we can use the formula:
Distance = I (a1, a2) - (b1, b2)I = √( (a1 - b1)^2 + (a2 - b2)^2)
Then in this case we have that:
Distance = √( ( -3 -(-3))^2 + (7 - (-4))^2) = √( 0 + 11^2) = 11
The distance between their houses is 11 units.
And we know that each unit represents 0.2 miles, then 11 units represent 11 times that amount, the distance in miles will be:
D = 11*0.2 miles = 2.2 miles.
11. Point F is on segment EG. If FG = (27x - 50)° and EF = (3x - 2)° and EG = 38,
then find FG. *
Answer:
Step-by-step explanation:
27x -50 + 3x - 2 = 38
30x - 52 = 38
30x = 90
x = 3
27(3) - 50 = 81 - 50 = 31 = FG

The area is square feet of a rectangular garden can be expressed as the product of the garden's length and
width, or A(x) = 2x2 - 21x + 40. If the width of the garden is (x - 8) feet, what is the length of the garden?
Answer:
(2x-5)feet
Step-by-step explanation:
The area of the rectangular garden A = Length × Width
Given the area A(x) = 2x² - 21x + 40
And the width =x-8 feet
To get the length, we will simply factorise the area function as shown;
You will just factorise the area
Factorizing 2x² - 21x+40
2x² − 21x + 40
2x² -16x - 5x + 40
2x(x - 8) -5(x - 8)
=(2x−5)(x−8)
Hence the length of the garden is
(2x-5)feet

If 40% of any number is 600 more than its 25%. What is the number?
Answer:
4000
Step-by-step explanation:
40% of the number is 15% more of the number than 15% of the number is. So, 600 is 15% of the number.
600 = 0.15n
600/0.15 = n = 4000
The number is 4000.
__
Check
40% of 4000 is 1600. 25% of 4000 is 1000. 1600 is 600 more than 1000.

Rectangle with width labeled on the right, width equals 4 and 1 over 2 inches. Below the rectangle, it says, length equals question mark. Inside the rectangle, it says area equals 36 and 3 over 4 square inches.
Answer:
length = [tex]8\frac{1}{6}[/tex] inches
Step-by-step explanation:
A rectangle is a quadrilateral which has opposite sides to be equal.
Area of a rectangle = length × width
Given that: Area = [tex]36\frac{3}{4}[/tex] square inches, width = [tex]4\frac{1}{2}[/tex] inches, length = l. Thus;
[tex]36\frac{3}{4}[/tex] = l × [tex]4\frac{1}{2}[/tex]
[tex]\frac{147}{4}[/tex] = l × [tex]\frac{9}{2}[/tex]
divide both sides by [tex]\frac{9}{2}[/tex],
l = [tex]\frac{147}{4}[/tex] ÷ [tex]\frac{9}{2}[/tex]
= [tex]\frac{147}{4}[/tex] x [tex]\frac{2}{9}[/tex]
= [tex]\frac{49}{6}[/tex]
l = [tex]8\frac{1}{6}[/tex]
Therefore, the length of the rectangle is [tex]8\frac{1}{6}[/tex] inches.
6) Marcy gave Juanita as many dimes as Juanita had. Then Juanita gave Marcy as many dimes as Marcy had left. Juanita now had 26 dimes and Marcy had 20 dimes. Originally, Marcy had( )dimes.
Answer:
0
Step-by-step explanation:
The original amount of dimes Marcy had before sharing with Jaunita is 52.
What is the solution to the word problem about dimes?Let's break down the given information step by step to determine the original number of dimes Marcy had.
Marcy gave Juanita as many dimes as Juanita had.
After this transaction, Juanita now has 26 dimes, and Marcy has x - 26 dimes, where x is the original number of dimes Marcy had.
Juanita gave Marcy as many dimes as Marcy had left.
After this transaction, Marcy now has 20 dimes, and Juanita has 26 - 20 = 6 dimes remaining.
From the above information, we can set up the following equation:
x - 26 = 20 + 6
Simplifying the equation:
x - 26 = 26
Adding 26 to both sides:
x = 52
Therefore, the original amount of dimes Marcy had is 52 dimes.

What is the value of x in the equation 32(4x – 1) – 3x = 54 – (x + 2)?
Answer:
Step-by-step explanation:
32(4x - 1) - 3x = 54 - (x+2) : Do 32 times 4 and -1 as well as -1 times x and 2
128x - 32 - 3x = 54 - x - 2 : Combine like terms
125x - 32 = 52 - x : Add x to both sides
126x - 32 = 52 : Add 32 to both sides
126x = 84 : Divide both sides by 126
x = 0.666666667 : Round to the tenth
x = 0.67 : Final answer

Dr. Watson received a $15 gift card to download music for her mp3 player. Each Song costs $1.50. Find the equation that represents the
remaining balance on the gift card after x downloads. What is a suitable domain for this function?
Answer:
y = -1.50x + 15, Domain is from 0 to 10
Step-by-step explanation:
First, look at the question carefully and highlight all the words that are important. We know that the 15 dollar giftcard is important, and we know that each song costs 1 dollar and 50 cents is important. We will make an equation out of this information. Since she is spending money, the value of X will be negated. She starts out with 15 dollars, so that will be our y-intercept. From this, the equation is y = -1.50x + 15. Next, let's look at the domain. We can see that the question asks for a suitable domain, not the domain of the function. Since she didn't have more than 15 dollars from her gift card, any domain from negative infinity until 0 will be crossed out. The x-intercept of this equation is 10, so any value above 10 will be crossed out since you cannot spend more money than you were given. The domain would now be from 1 to 10.
