Answer:
Step-by-step explanation:
We simplify 16x - 12 - 24x + 4 as -8x - 8
1. 4+16x - 12(1+2x)
Break the bracket out, we get : 4+16x-12+24x
Simplify : -8 + 40x, not equivalent to -8x - 8.
2. 40x - 16
Divide this by 5, we get : 8x - 3.2 = -8x + 3.2 (not equivalent also.)
3. 16x - 24x - 4 + 12
Simplify : -8x + 8 (also not equivalent)
4. -8x-8
It's literally the same as the simplified form of the expression.
So, only the fourth expression is equivalent to the original one.

Hi please help i am stuck with this question i will mark for brainliest
And 100. Point
Answers
Answer: 9
Step-by-step explanation:
First solve the system (using elimination):
x-y=7...(1)
3x+2y=26...(2)
Multiply equation 1 by -3
-3x+3y=-21
+ 3x+2y=26
-----------------
5y=5
y=1
Substitute y=1 into equation 1
x-y=7
x-(1)=7
x=8
Let a=8 (x=a) and y=1 (y=b)
a + b
= (8) + (1)
= 9
Information provided with us :
x is assumed as a y is assumed as bWhat we have to calculate :
Value of a + b ?Performing Calculations :
Here we have been given with two equations,
x - y = 7 (First equation) 3x + 2y = 26 (Second equation)From the first equation we would be getting a value of x and that value of x we would substitute in the second equation.
⇒ x - y = 7
⇒ x = 7 + y
Now, substituting it in the second equation :
⇒ 3x + 2y = 26
⇒ 3 (7 + y) + 2y = 26
⇒ 3 × (7 + y) + 2y = 26
⇒ 21 + 3y + 2y = 26
⇒ 21 + 5y = 26
⇒ 5y = 26 - 21
⇒ 5y = 5
⇒ y = 5 / 5
⇒ y = 1
★ Therefore, value of y is 1.
Now, substituting this value of y as 1 in the first equation.
⇒ x - y = 7
⇒ x - 1 = 7
⇒ x = 7 + 1
⇒ x = 8
★ Therefore, value of x is 8.
Value of a + b :-
⇒ x = a = 8
⇒ y = b = 1
Now,
⇒ a + b
⇒ 8 + 1
⇒ 9
Henceforth, value of a + b is 9.

Step-by-step explanation:
Combine like terms. Like terms are terms that have the same amount of the same variable:
Set the expression:

(12A + A) + (2 - 1)
13A + 1
13A + 1 is your answer.

Hey there!
12a + 2 + a - 1
COMBINE the LIKE TERMS
= (12a + 1a) + (2 - 1)
= 12a + 1a + 2 - 1
= 13a + 1
Therefore, your answer is: 13a + 1

In right triangle ABC below, CD is the altitude to hypotenuse AB. If CD=6 and the ratio of AD to AB is 1:5, determine and state the length of BD.
Answers
Step-by-step explanation:
the altitude makes a right angle at hypotenuse
cd^2+ ad^2 = ac^2
36+ (h/5)^2 = ac^2
ad/ab = 1/5; ad/h = 1/5; ad=h/5
similarly
bd^2+cd^2 = bc^2
(4/5)^2+ 36 = bc^2
ac^2+bc^2 = ab^2
36+h^2/25+ 16/25h^2+36 = h^2
h= 15
bd/ab = 4/5
bd= .8*15=12

My teacher is trash for math i need help
Answers
Answer:
Step-by-step explanation:
The first step is to figure out what the % is on the right.
The total is 100%
The left side is 60%
The right side is 100% - 60% = 40%
Now the 40% represents 28 students
The total number of students is 100%
40%/100% = 28/x Cross multiply
40% x = 28 * 100% Divide both sides by 40%
x = 28 * 100 / 40
x = 70
So the total number of students is 70
60% of them are on the left. 60/100 * 70 = 42
There are 42 students on the left.

Answer:
15 cm²
Step-by-step explanation:
To find the volume of a prism you multiply the area of the end face (pentagon in this example) by the length (9 cm). Here you would reverse that and divide the volume by the length to find the area. 135/9 is 15 so the area of the pentagon is 15 cm².
In equation form would be:
V=A×L [V=volume A=area L=length]
So if you do inverse operations you would divide the volume by the length to get the area.
V/L=A
