Answer:
15 equations
Step-by-step explanation:
Let
Number of equations in the homework = x
There is only a one-word problem
y = amount of time used to solve the word problem
She took 3 minutes to solve each equation, then 7 minutes to solve the word problem if it took her 52 minutes total,
Total = 3x + y
52 = 3x + 7
Subtract 7 from both sides
52 - 7 = 3x + 7 - 7
45 = 3x
Divide both sides by 3
x = 45 / 3
= 15
x = 15 equations
Therefore, she solved 15 equations

For the question 7 its congruent for 8 it's not congruent
Step-by-step explanation:
1. Calculate the slope of Graph D. Explain or show your reasoning
2. Calculate the slope of Graph E. What situation could the graph represent
3. On the blank grid , draw a line that passes through the indicated point and has the slope -2.
Answer:
Step-by-step explanation:
1). Slope of a line shown on the graph will be,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{-4}{1}[/tex]
= -4
2). Slope of the given horizontal line can be determined by,
Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
Since, rise of the given line is zero.
Therefore, slope of the given horizontal line will be 0.
3). Slope of the line passing through the indicated line = -2
Therefore, a line which has a rise = -2 and run = 1 can be drawn on the given blank grid (As attached).
Answer:
Step-by-step explanation:
1. -4. Explanations vary. Sample explanation: for each horizontal change of 1, the vertical change is -4, so the slope of the line is -4.
2. 0. Responses vary. Sample response: The amount of rainfall on a day with no rain.
3. A graph through the indicated point with a slope of -2.
If f(x) = -7x+1 and g(x) = -5x+3, what is (f+g)(x)?
Answer:
-12x + 4
Step-by-step explanation:
Just write the givens like this f(x) + g(x)
f(x) + g(x) = -7x + 1 + - 5x + 3
f(x) + g(x) = - 7x + 1 - 5x + 3
f(x) + g(x) = - 12x + 4

The sum of two consecutive numbers is 723. FInd the numbers.
Answer:
361 and 362
Step-by-step explanation:
a+b=723
b-a=1
b=1+a
a+1+a=723
2a+1=723
2a=723+1
2a=724
a=362
362+b=723
b=723-362
b=361
so b and a are 361 and 362 respectively
hence the consecutive numbers are 361 and 362

Answer:
48%
Step-by-step explanation:
If the coin is flipped 250 times, and lands on tails 120 times, set this up as a fraction. Put 250 on the bottom, and 120 on the top (because you want to know percentage of tails for 250 coin flips) to get 120/250. This is 0.48, to turn this into a percentage multiply by 100, 48%. You can check this answer by taking 0.48(250) and you will get 120.

What is the difference between 10 x 4 + 5 and 10 x (4 + 5).
Answer:
The difference is that in the first equations you multiply the 10 by 4 first because of PEMDAS rule. But in the second equation you add the 4 and 5 before multiplying. Thats the only difference :D
Step-by-step explanation:
I hope this helps!!!!
Answer:
[tex]10*4+5\\By\ applying\ BODMAS, as\ there\ are\ no\ brackets\ we\ directly\ multiply(M)\ 10\\ with\ 4\ and\ add(A)\ the\ product\ with\ 5.\\[/tex]
[tex]Hence,\\10*4+5\\=40+5\\=45[/tex]
[tex]10*(4+5)\\By\ applying\ BODMAS,\ due\ to\ the\ presence\ of\ the\ brackets\ we\ carry\\the\ operations\ inside\ the\ bracket.\\ Hence,\\10*(4+5)\\=10*9\\=90[/tex]

HELP QUICK PLS ILL GIVE BRAINLY
Answer:
1
Step-by-step explanation:
Algebraically, both sides of the equation must equal each other.
[tex]4(12x-6)=6(-4+5x)+18[/tex]
Distribute
[tex]4(12x-6)=6(-4+5x)+18\\48x-24=30x-24+18\\[/tex]
Add, subtract, multiply, or divide to isolate x.
[tex]48x-24=30x-24+18\\48x-24=30x-6\\18x=18\\x=1[/tex]
The solution to this equation is 1.
To test, you can plug in x with 1 and you will see that both sides equal each other.

Step-by-step explanation:
John earns $7.50 an hour. How many hours will John have to work to earn $600?
Divide John's goal amount by his hourly rate to find the answer.
$600 ÷ $7.50/hour = 80 hours.
So, John will have to work a total of 80 hours in order to earn $600.
Answer:
80
Step-by-step explanation:
If you divide 600 with 7.50 you will get 80.
That is simple!
Find the GCD (or HCF) of numerator and denominator
GCD of 600 and 750 is 150
Divide both the numerator and denominator by the GCD
600 ÷ 150
750 ÷ 150
Reduced fraction:
4
5
Therefore, 600/750 simplified to lowest terms is 4/5.

Solve the following system of equations and show all work.
Please show all work
Answer:
-1/2 and -1
Step-by-step explanation:
Our system of equations is:
y = 2x²
y = -3x - 1
We can set the y's equal to each other:
y = 2x² = -3x - 1
Now, we have:
2x² = -3x - 1
Move all the terms to one side by adding both sides by 3x and 1:
2x² + 3x + 1 = 0
We must factor this quadratic. Note that the factoring is:
(2x + 1)(x + 1) = 0
Our solutions are now:
2x + 1 = 0 OR x + 1 = 0
x = -1/2 x = -1
.
Thus, our solutions are -1/2 and -1.
Marta received $5 for helping her dad in the back yard. She spent $2.40 on drinks and $1.33 on snacks. A)Write an equation to show how much money she has left. Remember to define your unknown. B)Solve the equation from part (a). Show your work
Answer:
5-( 2.40+1.33 )= $1.27
Step-by-step explanation:
If you add $2.40 to $1.33 you get $3.73, the total amount of money she spent on drinks and snacks. Then you would need to subtract $3.73 from $5.00, which is $1.27.

An album sells for $16.00 through an online music service. If the album is 10% off, and sales tax is 8%, what is the total price of the album including tax? A. $15.70 B. $15.68 C. $16.42 D. $15.55
Answer: B. $15.68
Step-by-step explanation:
Given: Selling price of album = $16.00
Discount = 10% off
Sales tax = 8%
Discount = 10% of ( Selling price of album)
= 10% of $16
= 0.1 ($16)
= $1.6
Sales tax = 8% of ( Selling price of album)
= 8% of $16
= 0.08 ($16)
= $ 1.28
Total price of the album including tax = Selling price of album +Sales tax - Discount
= $ 16 + $1.28 - $1.6
= $ 15.68
Hence, B. is the correct option.
