Lily drives 90 miles in 2 hours. If she drives at the same rate, how far does lily travel in each of the following time intervals: 1 hour, 1/2 hour, and 3 hours? Please solve in at least two different ways. You could make a bar model, double number line, ratio table, or graph.
How far does she travel in 1/2 hour?
Answer:
22.5 miles 1/2 hour - 45 miles 1 hour - 67.5 miles 1.5 hours - 135 miles 3 hours
Step-by-step explanation:
If Lily travels 90mph in 2 hours she would travel 45mph each hour. So now just take 45 times 1, 1.5, and 3 to get your answers. So in half an hour she would travel 22.5 miles
1. A school has 400 students. They all come to school by bus, and each bus carries the same number of students. How many students might there be on each bus if each hold only 50 children?
Answer:
8
Step-by-step explanation:
400 divided by 50 is 8
Answer:50
there are 400 students and a bus can hold 50 so you divide 400 by 50 which is equel to 8
so about 50 kids if all the kids go on the bus

The weight of a giant panda is 10 times the weight of a red panda. The combined weight of the pandas is 220 pounds. What is the weight of each panda?
Answer:
The weight of a giant panda = x = 200 pounds
The weight of a red panda = y = 20 pounds
Step-by-step explanation:
Let
The weight of a giant panda = x
The weight of a red panda = y
The weight of a giant panda is 10 times the weight of a red panda.
x = 10y
The combined weight of the pandas is 220 pounds.
x + y = 220
We substitute 10 y for x
10y + y = 220
11y = 220
y = 220/11
y = 20 pounds
Solving for x
x = 10y
x = 10 × 20
x = 220 pounds
Hence:
The weight of each panda is:
The weight of a giant panda = x = 200 pounds
The weight of a red panda = y = 20 pounds

Which expression has the greatest value?
∣−25∣ ∣−16∣ ∣18∣ ∣−22∣
Answer: |18| is the greatest value.
Step-by-step explanation:
|-25|, |-16| and |-22| are all negative numbers. (Negative numbers are numbers that are less than zero.)|18| is a positive number. (Positive numbers are whole numbers that is larger than zero. On a number line these numbers come before zero and negative numbers)|18| is a greater value because it is a positive number.How many solutions does 6 -3x = 12 - 6x have?

Step-by-step explanation:
Sinah bought some packs of gum. There were 8 sticks of gum in each pack. She gave 12 sticks of gum to manuela. This left sinah with 28 sticks of gum. Which equation can be used to represent this situation where g is the number of packs of gum that sinah bought?
Answer:
8g = 12 + 28
g = 5 packs
Step-by-step explanation:
Share of the sticks of gum
Manuela = 12 sticks
Sinah = 28 sticks
There are 8 sticks in each pack
g = number of packs of gum that sinah bought?
g × 8 sticks = 12 sticks + 28 sticks
8g = 40
Divide both sides by 8
g = 40 / 8
g = 5 packs
Mr. Silverstone invested some money in 3 different investment products. The investment was as follows:
a. The interest rate of the annuity was 4%.
b. The interest rate of the annuity was 6%.
c. The interest rate of the bond was 5%.
d. The interest earned from all three investments together was $950.
Which linear equation shows interest earned from each investment if the total was $950?
a.) a + b + c = 950
b.) 0.04a + 0.06b + 0.05c = 9.50
c.) 0.04a + 0.06b + 0.05c = 950
d.) 4a + 6b + 5c = 950
Answer: c.) 0.04a + 0.06b + 0.05c = 950
Step-by-step explanation:
To find interest per investment you need to multiply the percentage interest rate by the value of the investment.
When written in linear equations, percentages are converted to decimal form.
4% = 1/100 = 0.04
6% = 6/100 = 0.06
5% = 5/100 = 0.05
These are the interest rates that when multiplied by their investments, will give a total of $950.
0.04 * a + 0.06 * b + 0.05 * c = 950
0.04a + 0.06b + 0.05c = 950
Option c is therefore correct.

A. Find an equation in point-slope form for the line having the slope m = 6 and containing the points (7,2)
B. Find an equation in point-slope form for the line having the slope m=-4 and containing the point (1,9).
Answer:
Part A)
An equation in point-slope form for the line having the slope m = 6 and containing the point (7,2).
[tex]y - 2 = 6(x-7)[/tex]
Part B)
An equation in point-slope form for the line having the slope m = -4 and containing the point (1, 9).
[tex]y - 9 = -4(x-1)[/tex]
Step-by-step explanation:
Part A)
Given
Slope m = 6
Point (7, 2)
To Determine
Find an equation in point-slope form for the line having the slope m = 6 and containing the point (7,2).
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case:
m = 6(x₁, y₁) = (7, 2)substituting the values m = 6 and the point (x₁, y₁) = (7, 2) in the point-slope form of line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 2 = 6(x-7)[/tex]
Therefore, an equation in point-slope form for the line having the slope m = 6 and containing the point (7,2).
[tex]y - 2 = 6(x-7)[/tex]
Part B)
Given
Slope m = -4
Point (1, 9)
To Determine
Find an equation in point-slope form for the line having the slope m = -4 and containing the point (1, 9).
Using the point-slope form of the line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
where
m is the slope of the line(x₁, y₁) is the pointIn our case:
m = -4(x₁, y₁) = (1, 9)substituting the values m = -4 and the point (x₁, y₁) = (1, 9) in the point-slope form of line equation
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y - 9 = -4(x-1)[/tex]
Therefore, an equation in point-slope form for the line having the slope m = -4 and containing the point (1, 9).
[tex]y - 9 = -4(x-1)[/tex]
The answer is:
1) y - 2 = 6(x - 7)
2) y - 9 = -4(x - 1)
Work/explanation:
The point slope formula is:
[tex]\bf{y-y_1=m(x-x_1)}[/tex]
where m = slope;
(x₁, y₁) is a point on the line.
For this problem, m = 6 and the point is (7,2).
Plug in the data:
[tex]\bf{y-2=6(x-7)}[/tex]
__________________
For this problem, m = -4 and the point is (1,9).
Plug in the data:
[tex]\bf{y-9=-4(x-1)}[/tex]
Hence, these are the equations.
