Answer:
Infinite/many
Step-by-step explanation:
3x + 7 + 2x = 5x + 7
3x + 2x + 7 = 5x + 7
5x + 7 = 5x + 7
5x - 5x + 7 = 7
7 = 7
Infinite solutions
Answer: many (all real numbers)
Step-by-step explanation:
1) add 2x and 3x to give you 5x
You now have 5x+7=5x+7
2) you can simplify this by subtracting 7 on both sides and dividing by 5
3) you are then left with x=x

General Formulas and Concepts:
Algebra I
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
Step 1: Define
[Slope-Intercept Form] y = 6x - 5
Step 2: Break Function
Identify Parts
Slope m = 6
y-intercept b = -5
Answer:
[tex]slope:6\\y-intercept:-5[/tex]
Step-by-step explanation:
Given the line:
[tex]y=6x-5[/tex]
We can first refresh our memory with slope-intercept form:
[tex]y=mx+b[/tex]
In slope-intercept form:
[tex]m=slope\\b=y-intercept[/tex]
With that information, using the given equation for the line, we can conclude that:
[tex]m=6[/tex]
[tex]b=-5[/tex]

What is the slope of the line 4x - 8y = 16 ?*
Step-by-step explanation:
4x - 8y = 16
8y = 4x - 16
y = 0.5x - 2
Hence the slope is 0.5.
Answer:
1/2
Step-by-step explanation:
Slope from a standard form equation is [tex]-\frac{A}{B}[/tex].
A is 4 and B is -8.
[tex]-\frac{A}{B}=\frac{-4}{-8}= \boxed{\frac{1}{2}}[/tex]

What is the gradient of the straight line 2y = -3x - 8 ?
Answer:
- [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope (gradient) and c the y- intercept )
Given
2y = - 3x - 8 ( divide all terms by 2 )
y = - [tex]\frac{3}{2}[/tex] x - 4 ← in slope- intercept form
with gradient = - [tex]\frac{3}{2}[/tex]
The gradient of the straight line 2y = -3x - 8 will be -1.5.
What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.
The slope(gradient) 'm' of any straight line is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
It is given that the equation of the line is, 2y = -3x - 8
Rearrange the equation in the standard form of the equation as
2y = -3x - 8
y=-3/2 x-8/2
y= -1.5x - 4
Compare the obtained equation with the standard equation,y=mx+b. Where m is the gradient of the straight line.
m= -1.5
Thus, the gradient of the straight line 2y = -3x - 8 will be -1.5.

Im really confused bc ive tried everything and i cant figure this out
-3 7/10 = -3/-4y
its a rational equation
Answer:
y = - [tex]\frac{15}{74}[/tex]
Step-by-step explanation:
Given
- 3 [tex]\frac{7}{10}[/tex] = [tex]\frac{-3}{-4}[/tex] y = [tex]\frac{3}{4}[/tex] y ( change the mixed number to an improper fraction )
- [tex]\frac{37}{10}[/tex] = [tex]\frac{3}{4}[/tex] y
Multiply through by 20 ( the LCM of 10 and 4 )
- 74 = 15y ( divide both sides by 15 )
- [tex]\frac{74}{15}[/tex] = y

A)7 in.
B)148 in.
C)92 in.
D)168 in.
Answers choices pls help
Answer:
The answer is 168 inches.
Step by Step Explanation: You divide 35in(the second triangle) by 15in(first triangle) and you get 2.33333333333. You then multiply that with 72 from the first triangle. That tells me that "x" stands for 168 inches.
Chang knows one side of a triangle is 13 cm. Which set of two sides is possible for the lengths of the other two sides
of this triangle?
5 cm and 8 cm
o 6 cm and 7cm
0 7 cm and 2 cm
8 cm and 9 cm
Calculate the area of this figure round your answer to the nearest 10th
Answer:
Step-by-step explanation:
the figure is a rectangle and a triangle
the rectangle has the area A=L x W
A=8*10=80ft^2
the triangle has the sides 6 and 8, with a hypothenuse of 10
A=(6*8)/2=24
the total area is 80+24=104 ft^2
A back patio has 127ft^2127 f t 2 of area in Brad's yard. If his patio is perfectly square, what is the side length of the patio? Round your answer to the nearest hundredths place. Group of answer choices 11.27 feet 11.3 feet 11 feet 11.25 feet
Answer:
The length of side of patio is 11.27 feet.
Option A is correct option.
Step-by-step explanation:
Area of patio = 127 ft^2
We need to find side length of the patio.
Since the patio is square, the formula used is:
[tex]Area\: of\: square = l^2[/tex]
where l is the side length of square.
Now, putting value of area we can find area of square.
[tex]Area\: of\: square = l^2\\127=l^2\\Switching\:sides\:\\l^2=127\\Taking\:square\:root\:on\:both\:sides\\\sqrt{l^2}=\sqrt{127} \\l=11.27[/tex]
So, the length of side of patio is 11.27 feet.
Option A is correct option.

A car is traveling at 45 miles per hour. Once the car starts to brake, it's speed (s) is related to the number of seconds (t) it spends braking according to the formula shown below. s=10t+45
Determine how many seconds it takes for the car to stop.
Answer: 55t
Step-by-step explanation:
The time taken by the car to stop is 1.28 seconds.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.
Given that a car is travelling at 45 miles per hour. Once the car starts to brake, its speed (s) is related to the number of seconds (t) it spends braking according to the formula shown below. s=10t+45.
The formula to calculate the speed is written as,
V = s / t
Here s = 10t + 45 substitutes the value in the formula and calculate the time,
45 = ( 10t + 45 ) / t
45t = 10t + 45
35t = 45
t = 45 / 35
t = 1.28 seconds

A restaurant has 44 waiters on permanent staff. It hires some temporary waiters during busy times of the year. Let t represent the number of temporary waiters and w represent the total number of waiters. Find the value of w when t=5.
Step-by-step explanation:
Since Total workers = Permanent + Temporary workers,
w = 44 + t.
Hence when t = 5, w = 44 + 5 = 49.

Jeremy has heard a lot of people in the club talking about tackling a 950-foot rock formation. Jeremy has set a limit that they won’t climb anything that takes longer than 7 hours, so they have enough time to travel to and from the place. Will it be possible to climb a 950-foot rock formation within Jeremy’s time constraint? Explain why or why not.
Answer:
Depends on how fast they climb. If we knew how fast they climb then we can tell, but without knowing how fast they climb we can't tell.
