Answer:
the fist one = 160 - 24
the second one = 12.50 / 5
Step-by-step explanation:
Answer:
15. equation: g+24=160, and the answer is g=136
16. equation: 5d=12.50, answer is d=3.5 hours
17. 15 cakes are made when the cost is $395
Step-by-step explanation:
15: You know that there are 160 students in 7th grade. This would be on one side of the equal sign. You know that there are 24 more students in the 7th grade class than the 8th grade class. And we know that g represents the number of students in the 8th grade class. So you set up your equation as g+24=160. You would subtract 24 from both sides: g+24-24=160-24, which gives you g=136.
16: You spend $5 an hour, so, on one side, you will have 5. On the other you will have $12.50. We will let d represent dollars, and it will go with the 5 to give us 5d. The equation is 5d=12.50. From there, you will divide 5 from both sides: 5d/5=12.50/5, which gives you d=3.5.
17: So, we have the equation, and we just plug in what we know. So, $395=24n+35. From there, we will subtract 35 from both sides. That would give us $395=24n and we will divide 24 from both sides to give us n=15 cakes.

Find the equation of the linear function represented by the table below in slope-intercept form.
x: 0,1,2,3,4
y: -6,4,14,24,34
Answer:
y = 10x - 6
Step-by-step explanation:
If we know the function is linear then we can use any two coordinate pairs to find the slope of the line.
Note that the first pair is (0, -6) and the last pair is (4, 34). The 'run' is from x = 0 to x = 4, a 'run' of 4. The 'rise' is from -6 to34, a 'rise' of 40. Thus, the slope of this line is m = rise / run = 40/4 = 10.
Again using the coordinate pair (0, -6), along with the slope-intercept form of the equation of a straight line, we get:
-6 = 10(0) + b, so we know that b = - 6 and that the equation of this line must therefore be:
y = 10x - 6
The required slope-intercept form of the function is y = 10x - 6.
The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.
Here,
m = (y₂ - y₁) / (x₂ - x₁)
Substitute 2 pairs from the table in the above equation,
m = (4 + 6)/(1-0)
m = 10
Now put the slope and one pair in the slope-intercept form of the equation
y - y₁ = m (x - x₁)
y + 6 = 10(x - 0)
y = 10x - 6
Thus, the required slope-intercept form of the function is y = 10x - 6

Step-by-step explanation:
you have to set 6x-7 equal to 5x-1 which equals x=8 which now you replace x in 6x-7 with 8 which makes the equation 6(8)-7 which equals 41.
Answer:
Since M is the midpoint that means that LM is equal to MN so therefore
6x-7=5x+1
-5x from both sides
x-7=1
add 7 to both sides
x=8
then you substutie 8 for x in 6x-7

The bar that represents the bar that would be the largest in a histogram would be 2/15.
How to identify the bar that would be largest in a histogram?To identify the bar that would be the largest in a histogram we must take each of the options and perform the division to obtain a decimal number. Once we have all the decimal numbers, we must identify which is the largest of them and thus we will know which one would represent a larger bar in a histogram. Here is the procedure:
1 / 10 = 0.11 / 15 = 0.061 / 30 = 0.032 / 15 = 0.13According to the above, the one that represents a larger bar would be 2 / 15 = 0.13

There are about 1.61 kilometers in 1 mile. Let LaTeX: xx represent a distance measured in kilometers and LaTeX: yy represent the same distance measured in miles. Write two equations that relate a distance measured in kilometers and the same distance measured in miles.
Answer:
1.61 x km= y miles
x km= y/ 1.61 miles
Step-by-step explanation:
Let x represent the distance in Kilometers and y represent the distance in miles then
1.61 x km= y miles
Now if we have 5 miles then
1.61(5) km = 5miles
8.05 km = 5 miles
Similarly if we want to express 1 km in miles the equation would be
x km= y/ 1.61 miles
So for 5 km the miles would be
5 km = 5/1.61 miles
5 km = 3.1055 miles

What is the linear equation in two variable?An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e. a and b respectively, are not equal to zero.
According to the given question
We have
Total number of problems in a math test = 7
Total points given to each problem if it is correct = 10
Every text taker receives points for taking a test = 30
Let x represents number of correct answers given by the test taker and f(x) be the total score earned by the test taker.
Now, the function or linear equation in two variable which represent the given scenario is
f(x) = 30 + 10x

Answer:
MP ⊥ LO ⇒ proved
Step-by-step explanation:
In the given figure
∵ m∠LPM = m∠MNO ⇒ given
∵ m∠MNO = m∠MPO ⇒ given
→ If the measure of an angle equals the measures of another two
angles, then the two angles must be equal in measures
∴ m∠LPM = m∠MPO ⇒ proved
∵ P ∈ line LO
∵ ∠ LPM and ∠MPO are adjacent angles
∴ ∠LPM and ∠MPO formed a pair of linear angles
→ The measure of the linear pair angles is 180°
∴ m∠LPM + m∠MPO = 180°
∵ m∠LPM = m∠MPO
→ That means the measure of each one is 180° divided by 2
∴ m∠LPM = m∠MPO = 180° ÷ 2
∴ m∠LPM = m∠MPO = 90°
∵ MP intersect LO at P and formed right angles at P
→ That means MP is perpendicular to LO
∴ MP ⊥ LO ⇒ proved
Jason had $6 in his lunch account at school on Monday. He spent $2 on lunch on Tuesday, deposited $7 on Wednesday and brought lunch from home. He bought lunch on Thursday for $5 and on Friday, he bought lunch again for $4. How much does Jason have on Friday AFTER he bought lunch?
Answer:
$2
Step-by-step explanation:
Credits:
Jason initial amount in his account = $6
Amount deposited for the week = $7
Total credit = $7+$6
Total credit = $13
Debit:
Cost of lunch bought on Tuesday = $2
Cost of lunch bought on Thursday = $5
Cost of lunch bought on Friday = $4
Total cost of lunch for the week = $2+$5+$4 = $11
Amount debited = $11
Balance left after he bought lunch on Friday = amount credited - amount debited
Balance = $13-$11
Balance = $2
Hence Jason had $2 balance left after buying his Friday lunch.

The school band is going to buy candy bars for $430 and sell them at school for $1.50 each. The band has to raise $1,350 to help pay for a trip. Write and inequality that represents how many candy bars x the band has to sell to make enough money for the trip.
Answer:
x = 900 or 1.50 * x = 1,350 (Though I advise you to use x = 900)
Step-by-step explanation:
Divide 1,350 by 1.50 to see that they need to sell exactly 900 bars. We can fact check by using a calculator to do the equation 1.50 * 900 = 1,350.

Circle A has a diameter of 8 inches, a circumference of 25.12 inches, and an area of 50.24 square inches. The diameter of circle B is 3 inches, the circumference is 9.42 inches, and the area is 7.065 square inches.
Part A: Using the formula for circumference, solve for the value of pi for each circle. (4 points)
Part B: Use the formula for area and solve for the value of pi for each circle. (4 points)
Part C: What observation can you make about the value of pi for circles A and B? (2 points)
The value of pi is about 3.14, and it is the same when using both the area and circumference.
How to calculate circumference?The circumference is given by:
Circumference = π * diameter
For circle A:
25.12 = π * 8
π = 3.14
For circle B:
9.42 = π * 3
π = 3.14
The area is :
Area = π * diameter² / 4
For circle A:
50.24 = π * (8²)/4
π = 3.14
For circle B:
7.065 = π * (3²)/4
π = 3.14
The value of pi is about 3.14, and it is the same when using both the area and circumference.
