5-3(2x-7)=2(7-3x)
What is true for the equation x=0, x=28, the equation has no solution or the equation has infinitely many solutions
Step-by-step explanation:
Part 1: 4x + 7 = 3(2x - 5)4x+7=3(2x−5)
4x+7=6x-154x+7=6x−15
7=6x-15-4x7=6x−15−4x
7=2x-157=2x−15
7+15=2x7+15=2x
22=2x22=2x
22=2x / 222=2x/2
x=11x=11
Part 2: Sam is not correct because he messed up the second step. He added 2x on both sides to get 7x, instead he should have subtracted.

Patty is inviting her friends to a party. She has 30 snack bars 45 juice boxed, and she wants to give the same number of each item to each friend.
help & not just comment for points thank youu
Answer:
For me it looks like downward and upward parabola.
The graph is periodical meaning that it repeats itself after some point. This is because the motion of the wheel makes the car move up and then come back down again. Each local min point is likely where the riders get on the ride, since its closest to the ground. Each local max point is the highest point on the graph indicating when the car is at the top of the wheel.
Let's say that the vertical distance from the lowest point to the highest point is 50 feet, just as an example. This would mean the amplitude is half that at 50/2 = 25 feet. The amplitude represents the vertical distance from the center line to either the highest or lowest point.
The period describes how long each cycle takes. For instance, if it takes 60 seconds for a specific car to go from the bottom position, loop around, and then come back to the bottom position, then the period is 60 seconds. The frequency is simply 1 over the period. Though the frequency may not be used as much.
So overall this curve is likely a sine or cosine curve (depending on the phase shift of course). Also there's a vertical shift as well. Because we don't have any numbers to work with, the actual sine or cosine function cannot be determined.

Brinlyn increased the amount of water she drank per day from 32 oz to 40 oz. By what percentage did Brinlyn increase the amount of water she drank each
day?
Answer:
20%
Step-by-step explanation:
If you ate 1/5 of the desert served at
dinner, what percent of the food did you
eat?
Answer:
20%
Step-by-step explanation:
so to become a percentage, you should multiply by 100% (which is basically 100/100 but don't multiply the bottom instead you write a percent sign)
So 1/5*100/100 without multiplying the bottom is:
100/5%
100 divided by 5 is 20. There you go! And you can use a calculator if that is easier for you. All you do is 1/5 which is .20 and your answer is 20%! Hope this helps!
To make homemade whipped cream the recipe calls for 1 ½ C of heavy cream, 1 ¼ t of vanilla, and 1 t. of sugar. This amount of whipped cream would be enough to cover one pie. If K makes 6 pies and covers them with whipped cream, how many teaspoons of vanilla will he need?
Answer:
7 1/2 teaspoons of vanilla
Step-by-step explanation:
From the above question,
The whipped cream for 1 pie contains
1 1/4 teaspoon of vanilla
Hence:
1 pie = 1 1/4 teaspoon of vanilla
6 pies = x
Cross Multiply
x = 6 × 1 1/4
x = 6 × 5/4
x = 30/4
x = 7 2/4
x = 7 1/2 teaspoons of vanilla
Hence: If K makes 6 pies and covers them with whipped cream, he would be needing 7 1/2 teaspoons of vanilla

What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given that,
Becca made 2 trays of rolls and biscuits.
Since in 1 tray there are 12 rolls and 6 biscuits.
Number of rolls in 2 tray = 2(12) = 24 rolls
Number of biscuits in 2 tray = 2(6) = 12 biscuits.

What is the slope of this line?
y+2=−2(x−3)
Answer:
-2
Step-by-step explanation:
The final equation is y= -2x+4, so the slope is -2
Answer:
The slope is -2
Step-by-step explanation:
This equation is in point slope form
(y-y1) = m(x-x1) where m is the slope and ( x1,y1) is a point on the line
y+2=−2(x−3)
y- -2=−2(x−3)
The slope is -2 and a point on the line is ( -3,-2)
Determine if the ordered pair (-5, -1) is a
solution of 2x - y =-11.
Answer:(-5,-1) is not an ordered pair
Step-by-step explanation:
the ordered pair (-5,-1) is directly related to the variables (x,y) making -5=x and -1=y
so to figure out if the ordered pair is a solution you just plug in the number into their respective variable.
so the equation then becomes 2 (-5) - (-1) = -11
once you solve for the left part of the equation you are then left with -9 = -11 which we know is false.

Answer:
n=30
Step-by-step explanation:
40/36=1.111111
1.111111 times 27=30
Answer:
n=30
Step-by-step explanation:
solve by simplifying both of the equations , the isolating the variable
Reduce the fraction with 9 27/36 divide top and bottom by 9 = 3/4
n/40=3/4 cross multiplication 4n = 120 ( divide both sides by 4 )
n=30

When gold medalist Ren Qian prepared for her dive from the 10 meter platform during the
Olympics, she looked out at her family sitting on the front row (level with the pool) at a 20°
angle of depression. How far away was Ren from her family (ground distance)? Round to the
nearest tenth of a meter.
Write answer like this: ##.# m.
(5 Points)
Enter your answer
Answer:
Ren was 27.5 meters away from her family.
Step-by-step explanation:
Ren Qian was at a height of 10 meters to the ground. Let the distance from her vertical point on the ground to her family (i.e the ground distance) be represented by x.
But the angle of depression is measured with respect to the horizontal plane, so;
the vertical angle = [tex]90^{o}[/tex] - 20°
= [tex]70^{o}[/tex]
Applying the appropriate trigonometric function, we have;
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
Tan [tex]70^{o}[/tex] = [tex]\frac{x}{10}[/tex]
⇒ x = 10 x Tan [tex]70^{o}[/tex]
= 10 x 2.7475
= 27.475
x = 27.5 meters
Ren was 27.5 meters away from her family.
