–8(4 + 3x) = -200
Idk what this is i need help
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{x = 7}}}}}[/tex]
Step-by-step explanation:
[tex] \sf{ - 8(4 + 3x) = - 200}[/tex]
Distribute -8 through the parentheses
[tex] \longrightarrow{ \sf{ - 32 - 24x = - 200}}[/tex]
Move 32 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{ - 24x = - 200 + 32}}[/tex]
The negative and positive integers are always subtracted but posses the sign of bigger integer
[tex] \longrightarrow{ \sf{ - 24x = - 168}}[/tex]
Divide both sides by -24
[tex] \longrightarrow{ \sf{ \frac{ - 24x}{ - 24} = \frac{ - 168}{ - 24}}} [/tex]
Calculate
[tex] \longrightarrow{ \sf{x = 7}}[/tex]
Hope I helped !

34
10.25
41
13.75

Which equation represents the relationship between the side length, x, and the perimeter, y?
Answer:
the perimeter of square is 4 times of side of that square.
Explanation:
Side length (x) perimtr (y)
4.5 4 × 4.5 =18
8.5 4 × 8.5 =34
10.25 4 × 10.25 =41
13.75 4 × 13.75= 55
thus
y = ( x)2

Answer:
F= -103/-4d^4+d
Step-by-step explanation:
fd=4d2dfd−2−101
Step 1: Add -4d^4f to both sides.
df+−4d4f=4d4f−103+−4d4f
−4d4f+df=−103
Step 2: Factor out variable f.
f(−4d4+d)=−103
Step 3: Divide both sides by -4d^4+d.
f(−4d4+d)
−4d4+d
=
−103
−4d4+d
f=

Favian received a $100 gift card to a clothing store.
Using only the gift card, he was able to purchase n
sweaters that cost $32 each and 1 belt for $20. If there
was no tax on the sweaters and belt, which of the
following must be true?
Answer:
32n = 100 - 20
n = 2.5
he purchased 2 sweaters
Step-by-step explanation:
32n = 100 - 20
If Favian originally had $100 but spent $20 on a belt, he only had 80 left, meaning that 80 = 32n which means that he was able to but 2 sweaters and got $16 back. Therefore the formula would be 32n = 100 - 20
The formula for the number of sweaters will be 32n = 100 – 20.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Favian received a $100 gift card to a clothing store.
Using only the gift card, he was able to purchase n sweaters that cost $32 each and 1 belt for $20.
If there was no tax on the sweaters and belt,
Then the equation will be
32n + 1 x 20 = 100
32n + 20 = 100
32n = 80
n = 2.5 ≈ 2
If Favian originally had $100 but spent $20 on a belt, he only had 80 left, meaning that 80 = 32n, which means that he was able to but 2 sweaters and got $16 back.
Therefore, the formula would be 32n = 100 – 20.

Find the value of x and YZ if Y is between X and Z. Draw, label, set up the equation and solve each for :
4. XY = 5x, YZ=x, and XY=25
5. XY = 12, YZ=2x, and XZ = 28
7. XY=2x + 1. YZ = 6x, and XZ=81
6. XY = 4x. YZ=3x, and XZ = 42
Step-by-step explanation:
We need to find the value of x for all problems if Y is between X and Z.
For all cases, XZ = XY+YZ
4. XY = 5x, YZ=x, and XZ=25
Putting all values
25 = 5x + x
25 = 6x
[tex]x=\dfrac{25}{6}[/tex]
5. XY = 12, YZ=2x, and XZ = 28
28 = 12 + 2x
x = 8
6. XY = 4x. YZ=3x, and XZ = 42
XZ = XY+YZ
42 = 4x + 3x
42 = 7x
x = 6
7. XY=2x + 1. YZ = 6x, and XZ=81
XZ = XY+YZ
81 = 2x + 1 + 6x
80 = 8x
x = 10

The first term of an AP is -76 and the sum of first 45 terms is -9360. Which of the following is the last term of this AP
Answer:
- 340
Step-by-step explanation:
The sum to n terms of an AP is
[tex]S_{n}[/tex] = [tex]\frac{n}{2}[/tex] ( a + l ) → a is the first term and l the last term
Here a = - 76 and [tex]S_{45}[/tex] = - 9360 , thus
[tex]\frac{45}{2}[/tex] ( - 76 + l ) = - 9360
22.5(- 76 + l) = - 9360 ( divide both sides by 22.5 )
- 76 + l = - 416 ( add 76 to both sides )
l = - 340 ← the last term in the sequence

Larry ran 4/5 of the way around the track before slowing down to a walk. What percent of the track did he run? *
Answer:
80%
Step-by-step explanation:
4 divided by 5 = 0.8
0.8 x 100 = 80%
The percentage Larry ran around the track = 80%
He ran 4/5 of the way around the track before slowing down for a walk.
This means he ran 4 parts of the whole 5 parts of the track. He walks the remaining 1 part around the track.
Therefore, the percentage he ran can be calculated below
% he ran the track = 4 / 5 of 100
% he ran the track = 4 / 5 × 100 = 400 / 5 = 80%
The percentage he ran around the track = 80%

PLEASE ANSWER At a basketball game, 75% of people attending were supporting the home team, while 25% were supporting the visiting team. If 750 people attending the game supported the home team, what was the total number of people attending the game?
75% = 0.75
750 people / 0.75 = 1,000 people
There were 1,000 total people attending the game
Answer:
1,000 people
Step-by-step explanation:
At a basketball game, 75% of people attending were supporting the home team, while 25% were supporting the visiting team. If 750 people attending the game supported the home team, the total number of people attending the game was 1,000 people.
75% = 3/4 or 0.75
25% = 1/4 or 0.25
We need to find what 25% is.
75/3=25
75% = 0.75
750 people / 0.75 = 1,000 people
Therefore, there were 1,000 people at the game.
