how is 3x(6+4)-2x4=96 wrong?
Answer:
well, yes. there a variable (x) is there which isn't in the '96' answer so that's one reason.
Step-by-step explanation:
And your answer is 100% wrong, the correct answer is 30x - 8
now I won't let you down so here it is:
a useful mathematical term(s) is PEMDAS ( Parenthesis, exponent, Multiplication, division, addition, subtraction)
first: the P:
3x(6+4)-2 * 4 >> 3x (10) -2 *4
second: since there are no Exponents you skip to M:
3x(10) - 2 * 4 >> 30x - 8
and done because 30x and 8 are not like terms so this is as far as you go!
Bonus: like terms ex: 8 + 8 or 30x + 30x are like terms so you cant do 30x - 8!
Hope it helps!

A necklace that regularly sells for $88.40 is on sale for 25% off. Find the
sale price of the necklace
Answer:
66.3
Step-by-step explanation:
First, you need to find the 25% of $88.40.
88.40×25% (or) 25/100 = □/88.40
Solve that and you should get 22.10.
22.10 is 25% of $88.40
Finally, subtract your percent from original price and boom!
88.40 - 22.10 = $66.30

find the slope of a line through points (5,-8) and (-2,0)
Answer:
The slope of line through the points (5,-8) and (-2,0) is [tex]-\frac{8}{7}[/tex]
Step-by-step explanation:
Given points are:
(5,-8) and (-2,0)
Slope is the steepness of a straight line.
Slope of the line = m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
We will find the slope of the line through points (5,-8) and (-2,0) by putting values in the formula of slope
Here,
[tex]x_1= 5, y_1=-8\\x_2=-2, y_2=0[/tex]
Slope of the line = [tex]\frac{0-(-8)}{-2-5}[/tex]
Slope of the line = [tex]\frac{8}{-7}=-\frac{8}{7}[/tex]
Hence,
The slope of line through the points (5,-8) and (-2,0) is [tex]-\frac{8}{7}[/tex]
On a math test, 30 students earned a B. This number is exactly 40% of the total number of students in the class. How many students are in the class
The number of students in the class will be 75.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that on a math test, 30 students earned a B. This number is exactly 40% of the total number of students in the class. The number of the students will be calculated as below:-
40% of the students = 30
1 % of the students = 30 / 40
100% of the students = ( 30 / 40 ) x 100
100% of the students = 3 x 25 = 75
Therefore, the number of students in the class will be 75.

$43
Step-by-step explanation:
Given
[tex]Savings = \$88[/tex]
[tex]Earnings = \$29[/tex]
[tex]Amount\ Left = \$74[/tex]
Required
Calculate the amount spent
First, we need to calculate the total amount she had.
[tex]Total = Savings + Earnings[/tex]
[tex]Total = \$88 + \$29[/tex]
[tex]Total = \$117[/tex]
Represent amount spent with x.
The relationship between total amount, spending and amount left is:
[tex]Total - x = Amount\ Left[/tex]
[tex]\$117 - x = \$74[/tex]
Collect Like Terms
[tex]x = \$117 - \$74[/tex]

In this situation, all of the angles can only be either 108 degrees or 180 - 108 degrees. 180 - 108 = 72 degrees.
So <2 = 108 because it obtuse and corresponding and angle 4 is acute and = 72 degrees.
shopkeeper purchased a bicycle for rupees 5000 and marked its price a certain percent above the cost price then he sold it at 10% discount if a customer paid rs 6356.25 with 13% vat to buy it .how many percent is the Marked price above the cost price?
Lets say the final price of the bike is SP plus 13% VAT. So:
1.13 * SP = 6356.25
SP = 5625
Now SP was after 10% discount on Original Price, say MP. So:
0.9 * MP = 5625
MP = 6250
Therefore, the percent of Marked Price above Cost Price is:
(6250 - 5000) * 100/5000 = 25%
A person's score on a Mad Minute is proportional to the amount of questions he or she answers correctly. Each Mad Minute lasts the same amount of time. On her first test, Rachel earned a score of 70 when she answered 25 questions correctly. Rachel says this relationship can be modeled with an equation.
Answer:
s = 2.8y
Step-by-step explanation:
Score is proportional to the amount of correctly answered question :
Given that:
Score earned by Rachael = s =70
Number of correctly answered question = y = 25
Hence,
Score α number of correctly answered question
s = ky
70 = 25k
k = 70/25
k = 2.8
Hence, one correct answer gives 2.8
Hence,
Score obtained = 2.8 * number of questions answered correctly
s = 2.8y

Tyler filled up his bathtub, took a bath, and then drained the tub. The function
gives the depth of the water, in inches, 7 minutes after Tyler began to fill the bathtub.
Explain the meaning of each statement in this situation
A.B(0)=0
B.B(1)
C.B(9)=11
Help me!!!!!
Answer:
B(0) = 0 depth in inches 0 minutes after filling began is 0 ; that is at time = 0 ; depth = 0
B(1) represents the function one minutes after filling began.
B(9) = 11 depicts that the depth in inches if water 9 minutes after filling began is 11.
Step-by-step explanation:
The function gives depth of water in inches 7 minutes after filling began
A.) B(0)=0
The statement B(0) = 0 means the depth in inches 0 minutes after filling began is 0 ; that is at time = 0 ; depth = 0
B.) B(1)
B(1) represents the function one minutes after filling began.
C.B(9)=11
B(9) = 11 depicts that the depth in inches if water 9 minutes after filling began is 11.
15. What is -130 = -9k - 4
Answer: 14
Work: First, we must get rid of the four from the side it's currently on. So, we are going to add it on both sides. After adding four on both sides, I'll cancel on the side it was on, and the new equation is -126 = -9k. Now, we are going to divide -9 on both sides and yet again, I'll cancel on the side it was on. The answer is k = 14. It's a positive 14 because we divided a negative by a negative, and after doing so, the new number is a positive.
