Answer:
There was a mistake in line D
===========================================================
Explanation:
Note in the previous line C that Noah multiplied both sides by 5. This is to clear out the fractions, since each have a denominator of 5.
In line D, Noah only multiplied those outer '5's by the first term in each parenthesis group. He didn't use the distributive property correctly.
The distributive property is a*(b+c) = a*b+a*c.
The 'a' is multiplied to everything inside, which are the terms b and c.
-------------------------------
Here are what the steps should look like from line D and onward. Take note of the 30 and 100. This is from 5*6 = 30 and 5*20 = 100.
D) 7*14 - 30 = 12*14 - 100E) 98 - 30 = 168 - 100F) 68 = 68We end up with the same thing on both sides. So this confirms that x = 14/5 is the solution to the original equation.

An angle measures 110.8° more than the measure of its supplementary angle. What is the measure of each angle?
Answers
Answer:
34.6 and 145.4
Step-by-step explanation:
x+(x+110.8) = 180
2x= 180-110.8
2x= 69.2
x= 34.6
Measure of each angle:
x= 34.6
x+110.8 = 34.6 + 110.8 = 145.4

In a sale, the selling price of a bicycle is reduced by 20%. Find the sale price of the bicycle, given that its normal selling price is Rs 3300.
Answers
Answer:
1-0.2=0.8
0.8*3300= 2640
Original price = 3300
sale = 20% = 3300×20/100 = 660
Selling price= 3300-660= 2640 rs
the sale price of the bicycle is 2640 Rs

Grace needs to buy a new printer. The printer she wants has a price tag of $60. She has a 25% off coupon and $50 in her bank account. If she must pay 6.75% sales tax, will she have enough money to buy the printer? If yes, how much will she have left over? If no, how much is she short?
Answers
Answer:
Yes, she will have $1.96 left
Step-by-step explanation:
Initial cost : $60
Discount : 25%=0.25
Calculating discount : 60 * 0.25 = 15
Calculating cost after discount : 60-15 = 45
Sales tax : 6.75%=0.0675
Calculating sales tax : 45 * 0.0675 = 3.0375≈$3.04
Calculating final cost : 45+ 3.04 = $48.04
Can she buy the printer : 50 - 48.04= $1.96
Answer : yes
Yes, she has enough money to buy the printer. Then the balance of her account will be $ 1.9625.
What is percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol 'percent' is used to symbolize it.
Grace needs to buy a new printer.
The printer she wants has a price tag of $60.
She has a 25% off coupon and $50 in her bank account.
If she must pay 6.75% sales tax.
Then the price of the printer after the discount of 25% and the sales tax of 6.75% will be
Cost = $ 60 x (1 - 0.25) x 1.0675
Cost = $ 60 x 0.75 x 1.0675
Cost = $ 48.0375
Yes, she has enough money to buy the printer.
Then the balance of her account will be
Balance = $ 50 - $ 48.0375

A Profits increased by an average of $10,600 per year
from Year 2 to Year 4.
B Profits increased by an average of $21,600 per year
from Year 2 to Year 4.
C Profits decreased by an average of $21,600 per year
from Year 2 to Year 4.
D Profits decreased by an average of $10,600 per year
from Year 2 to Year 4.
Answers
Answer:
Step-by-step explanation:
Hi, Emily. The average rate of change can be calculated by adding all the profits together and dividing by the different profits (4 profits all together A to D) so 10,600+21,600+-21,600+-10,600= 0
0/4= 0
So we can best describe this as 0 or nothing at all as it hasnt changed from year 2 to 4.

The 17 students on the varsity basketball team want to raise 857.11 to buy new game jerseys,they have already raised 218.25,if each student raises the same amount,how much more money must each other raise?
Answers
Answer:Each of the 17 students will need to raise 37.58 each
Step-by-step explanation:
Total amount needed to be raised =857.11
Amount of money already raised =218.25,
Amount of money required to complete the amount needed to be raised =857.11 -218.25=638.86
Since there are 17 students to raise the money, Each student will raise
638.86/17=37.58
Each of the 17 students will need to raise 37.58 each to complete the money

Answers
Answer:
Step-by-step explanation:
To solve this problem you need the function
h(t) = -16t2 + v0t + h0
where t = time
v0 is the initial velocity, which in our case is 0
h0 = initial height, which in our case is 256
h(t) = 0 since we want to know when the ball will hit the ground.
0 = -16 t2 + 256
And we can solve for t
If we rearrange the terms we see that this is a difference of 2 squares
0 = 256 - 16t2
0 = (16-4t)(16+4t)
Setting each factor = 0
16-4t=0 16+4t=4
t = 4 t = -4
The second solution is discarded as time cannot be negative.
So the ball will hit the ground in 4 seconds.
Set up the equations to determine s and t.
