Answer:
It is wrong because she should simplify both sides of the equation,distribute, combine like terms,subtract and divide to get the final answer.
4x−2(3x−4)+4=−x+3(x+1)+1
Step 1: Simplify both sides of the equation.
4x−2(3x−4)+4=−x+3(x+1)+1
4x+(−2)(3x)+(−2)(−4)+4=−x+(3)(x)+(3)(1)+1(Distribute)
4x+−6x+8+4=−x+3x+3+1
(4x+−6x)+(8+4)=(−x+3x)+(3+1)(Combine Like Terms)
−2x+12=2x+4
−2x+12=2x+4
Step 2: Subtract 2x from both sides.
−2x+12−2x=2x+4−2x
−4x+12=4
Step 3: Subtract 12 from both sides.
−4x+12−12=4−12
−4x=−8
Step 4: Divide both sides by -4.
−4x−4=−8−4

Renee used the values in the table to calculate simple interest.
Principal $750
Interest rate ?
Time 11 years
Interest $412.50
Which interest rate is missing from Renee’s table?
0.05%
0.5%
5%
50%
Answer:
5% hope its correct
Step-by-step explanation:
The rate of Interest is 55.
What is Simple Interest?Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.
Given:
Principal= $750
Time = 11 years
Interest= $412.50
Using Simple Interest
SI= (PRT)/100
412.5 = (750 x R x 11) 100
41250 = 8250R
R= 5%
Hence, the rate of Interest is 55.

Find the slope of the line that contains (1, 6) and (10.-9).
Answer:
-5/3
Step-by-step explanation:
m=−9−6/10−1
m=−15/9
Slope=
−15/9=−5/3
What is the slope of a line with the equation y = 5x + ⅖ ?
Answer:
The slope would be 5
Step-by-step explanation:
The reason why it would be five is because the slope formula is y=mx+b with m being your slope and b being your y-intercept.
Answer:
slope: 5
Step-by-step explanation:
[tex]y=mx+b[/tex] is the equation used to find the slope of an equation. The slope is ALWAYS the "m" value. So.... in this equation y=5+2/5... the "m" value is 5.... making the slope of the equation 5.

1.) Select the correct equation for the following situation. Mariana had 134
crystals in her collection. This was 38 less than Rajesh's collection. How
many crystals are in Rajesh's collection?
38r = 134
r+ 38 = 134
r - 38 = 134
38 - r = 134
Answer:
r minus 38 equals to 134 this might be m not certain
The correct equation is, [tex]r-38=134[/tex] and Rajesh have 172 crystals .
Let us consider that, Rajesh had r crystals.
Mariana had 134 crystals in her collection.
Since, Rajesh has 38 more crystal than Marina . So , if we subtract 38 from crystals Rajesh have then both have equal number of crystals.
So, [tex]r-38=134[/tex]
Now, find crystals present in Rajesh collection.
[tex]r-38=134\\\\r=134+38=172[/tex]
Thus, Rajesh have 172 crystals .

Tony hit 9 out of 15 pitches at baseball practice yesterday. The following day at practice 45 pitches were made. How many pitches did Tony miss?
Answer:
18 pitches.
Step-by-step explanation:
I'm assuming the "9 out of 15" is the fraction of pitches Tony hit at baseball practice.
Hence, Tony missed 6 out of 15 pitches.
6/15 * 45
= 6 * 3
= 18 pitches.
Hope this helped!
Answer:
18
Step-by-step explanation:
You have to start with how many he hit.
Let the number of pitches he hit = x
9/15 = x / 45 Cross multiply
15x = 9 * 45 Combine the right side
15x = 405 Divide by 15
x = 405/15
x = 27
===================
The number he missed is 45 - 27 = 18

You are starting a savings account for college. You put
$1,000 in as your starting balance. You earn simple
interest at 10% every year. You also must pay 30%
income tax on the interest earned annually. Calculate
the interest, balance, tax paid, and the overall balance
of the account after taxes. To break the code determine
the accounts overall balance for year 5 after taxes after
been paid.
Answer: $4,000
Step-by-step explanation:
If you have $1,000 dollars, and take ad ten percent ($100) interest you would get $1,100. But If you take away 30 percent ($300) away from 1,100 dollars you would get $800 dollars. The over all balance on the account after five years is, $4,000.

What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, There are 11 books on a shelf, and 7 of these books are new.
So, The number of old books are (11 - 7) = 4.
So, In the self there is 7 new books and 4 old books.
