Answer: 3.25
Step-by-step explanation:
Sarah made a.mistaje when she was reducing 26 ÷ 8. It should be noted that 2 is a common factor to 26 and 8. Therefore 26÷2 = 13 and not 14 that Sarah wrote. Sarah should have written 13 ÷ 4 and not 14 ÷ 4.
26 ÷ 8 in decimal will give us 3.25
The difference between two num-
bers is 24. What are the numbers
if their sum is 78?
(Please help me!)
Answer:
51 and -27
Step-by-step explanation:
The sum of two numbers is 24 and their difference is 78. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 24. In other words, x plus y equals 24 and can be written as equation A:
x + y = 24
The difference between x and y is 78. In other words, x minus y equals 78 and can be written as equation B:
x - y = 78
Now solve equation B for x to get the revised equation B:
x - y = 78
x = 78 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 24
78 + y + y = 24
78 + 2y = 24
2y = -54
y = -27
Now we know y is -27. Which means that we can substitute y for -27 in equation A and solve for x:
x + y = 24
x + -27 = 24
X = 51
Summary: The sum of two numbers is 24 and their difference is 78. What are the two numbers? Answer: 51 and -27 as proven here:
Sum: 51 + -27 = 24
Difference: 51 - -27 = 78
Answer:
The numbers are 27 and 51
Explanation
x - y = 24
x + y = 78
Add together the equations
2x = 102
x = 51
Put into equation
51 - y = 24
27 = y

A company collected $7,800 by selling shoes. The company had $6,084 left after paying the tax. What was the percentage of tax?
Answer:
22%
Step-by-step explanation:
The percentage of tax can be found by calculating the percent change.
new - old / old
6084 - 7800 / 7800
= -0.22 or -22%
This means the price decreased by 22%, meaning you paid 22% in taxes.

Answer:
The answer is 15
Step-by-step explanation:
125/5=25
25-10=15
An= 5[15+10]=125
Compare the process of solving
|x - 11 + 1 < 15 to that of solving
|x - 11 + 1 > 15.
Answer:
I have solved them but I don't know what to o next
Step-by-step explanation:
1) lx- 11+ 1< 15
+11 on both sides
lx+ 1< 26
-1 on both sides
lx< 25
2) lx-11+1>15
+11 on both sides
lx+1>26
-1 on both sides
lx> 25
Answer:
Both absolute values would need to be isolated first.
You would need to write a compound inequality for each.
Both compound inequalities would compare
x – 1 to –15 and 15.
The inequality with “<” would use an “and” statement, while the “>” would use an “or” statement.

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.

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

Marcel is purchase a boad to build a bookcase he wants to divide the board into 1.75-foot sections he needs 6 sections what size board dose marcel need.
Answer: 10.5 feet
Step-by-step explanation:
From the question, we are informed that Marcel is purchasing a board to build a bookcase he wants to divide the board into 1.75-foot sections and that he needs 6 sections.
The size of the board that Marcel need will be calculated by multiplying 6 by 1.75 foot. This will be:

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.

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.

Answer:
y=5/2x-16
Step-by-step explanation:
First, we want to find the slope of the original line.
m= -4+8/-1-9
m= 4/-10
m= -2/5
Because we want the perpendicular bisector, we will need the slope to be the opposite reciprocal. Therefore, our slope is
m=5/2
Now, we want to find the midpoint of the line.
9-1/2
8/2=4
-8-4/2
-12/2= -6
So, the midpoint is (4,-6)
Using the information we have, we now can find b.
-6=5/2(4)+b
-6=10+b
-16=b
That gives us our equation
y=5/2x-16
Can anyone show me how to solve this problem? I know that its 5 weeks. (The problem is “Ahmed is saving his money to buy a Ipad that costs $319.50. Right now he has $21.95, and can save $63.00 each week. How many weeks will it take for Ahmed to have enough money to buy the Ipad)
Answer:
5 weeks
Step-by-step explanation:
Substract 319.5 (the amount he has to save) to the amount he has already saved, which is 21.95. Now the constant amount of change is 63 dollars each week so divided it by that. So the equation should be (319.5-21.95) and divide all that by 63 to get 4.72 or rounded to the nearest number, is 5.

What are simultaneous equation ?"Simultaneous Equation is an essential Chapter in the Algebra branch of Mathematics. There are times when you come across two or more unknown quantities and two or more equations relating to them. These are called Simultaneous Equations. When you are asked to solve such equations, you must find values of the unknowns which satisfy all the given equations at the same time. They are Simultaneous Equations because the equations are solved at the same time. Simultaneous Equations need algebraic skills to find the values of letters within two or more equations."
Given, The equations
[tex]2x + 3y = 10[/tex] ----------- eq 1
[tex]4x - y = -1[/tex] ------------ eq 2
multiplying eq 1 by 2
[tex]4x + 6y = 20[/tex] ----------- eq 3
