Given that 6x – 5y = 14
Find x when y = 2
Answer:
x = 4
Step-by-step explanation:
Given
6x - 5y = 14 ← substitute y = 2 into the equation
6x - 5(2) = 14
6x - 10 = 14 ( add 10 to both sides )
6x = 24 ( divide both sides by 6 )
x = 4
Answer:
[tex]\huge\boxed{\sf x = 4}[/tex]
Step-by-step explanation:
[tex]\sf 6x-5y = 14\\\\Put \ y = 2\\\\6x - 5(2) = 14\\\\6x - 10 = 14\\\\ Adding \ 10 \ to \ both \ sides\\\\6x = 14+10\\\\6x = 24\\\\Dividing \ both \ sides \ by \ 6\\\\x = 24 / 6\\\\x = 4\\\\\rule[225]{225}{2}[/tex]

Sally sold half of her comic books and then bought eight more. She now has twelve. How many did she begin with?
Answer:
8
Step-by-step explanation:
Since she now has 12, subtract 8 because of the 8 she before added.
Now, you're left with 4.
The 4 is half of what she originally had, leading up to the fact that the answer is 8.
Sally began with eight comic books.

C) On average, children grow about 9 inches every 2 years.
Step-by-step explanation:
Think about what the slope 9/2 means:
Slope is Change in Y / Change in X which is Change in Height / Change in Age, so 9 inches / 2 years means that on average, children grow about 9 inches every 2 years.

For every 3 dozen cookies, a bakery uses 8 cups of butter. How many dozen of cookies could you make with 20 cups of butter?
Answer:
7 1/2 dozen of cookies
Step-by-step explanation:
If for every 3 dozen cookies, a bakery uses 8 cups of butter then we can say;
3 dozens cookies = 8 cups of butter
x cups of cookies = 20 cups of butter
Cross multiply
8*x = 3 * 20
8x = 60
x = 60/8
x = 7 4/8
x = 7 1/2
Hence you will need 7 1/2 dozen of cookies

One year after you buy a tree, it is 10 feet tall. Each year after you buy the tree, it grows 2 feet. Write a function that represents the arithmetic sequence (1,10),(2,12),(3,14). How long does it take for the tree to reach its maximum height of 28 feet?
Answer:
10 years
Step-by-step explanation:
We are told that One year after you buy a tree, it is 10 feet tall. Thus, it's initial height after 1 year is 10 ft.
Now we are told that each year after you buy the tree, it grows 2 feet. This means that it's height after you bought it was; f(0) = 10 - 2 = 8ft
Thus,
f(1) = 8 + 2 = 10
f(2) = 8 + 2 + 2 = 12
f(3) = 8 + 2 + 2 + 2 = 14
The pattern here is;
f(x) = 8 + 2x
Where x is number of years
Thus, for it to reach a maximum height of 28 ft;
28 = 8 + 2x
Subtract 8 from both sides to give;
28 - 8 = 2x
2x = 20
x = 20/2
x = 10 years

Answer:
XZ ≈ 14.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle, that is
cos29° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{YZ}{XZ}[/tex] = [tex]\frac{12.6}{XZ}[/tex] ( multiply both sides by XZ )
XZ × cos29° = 12.6 ( divide both sides by cos29° )
XZ = [tex]\frac{12.6}{cos29}[/tex] ≈ 14.4 cm ( to 3 significant figures )

You want to rent a car for the day.Prestige car rentals charges $47 plus $0.07 per mile to rent a midsize vehicle . Gateway Auto changes a $35 fee plus $0.12 per mile for the same car. For what number of miles will both companies charge the same price?
Answer:
240 miles
Step-by-step explanation:
Given that:
Charges offered by Prestige car rentals for renting a midsize vehicle:
Fixed charges = $47
Per mile charges for renting a midsize vehicle = $0.07
Charges offered by Gateway Auto for renting a midsize vehicle:
Fixed charges = $35
Per mile charges for renting a midsize vehicle = $0.12
To find:
Number of miles for which both the companies charge the same price?
Solution:
Let the number of miles for which both the companies will charge the same price = [tex]x[/tex] miles
Charges for one mile by Prestige car rentals = $0.07
Charges for [tex]x[/tex] miles by Prestige car rentals = $0.07[tex]x[/tex]
Total charges by Prestige Car rentals = $47 + $0.07[tex]x[/tex]
Charges for one mile by Gateway Auto = $0.12
Charges for [tex]x[/tex] miles by Gateway Auto = $0.12[tex]x[/tex]
Total charges by Gateway Auto = $35 + $0.12[tex]x[/tex]
As per question statement, the charges are same:
[tex]\$47 + \$0.07x = \$35 + \$0.12x\\\Rightarrow 12=0.05x\\\Rightarrow x=\dfrac{1200}{5}\\\Rightarrow \bold{x=240\ miles}[/tex]

Answer:
to find the total number of miles traveled, you have to add the total distance from point L to point M together. 929+ 595 = 1,524 total miles traveled
to find the average miles per hour, you divide the total miles traveled, by the amount of time it took. 1,524 / 3 = 508 miles per hour
Step-by-step explanation:
Answer:
Step-by-step explanation:
LV to Colorado Springs = 595 miles
Colorado Springs to Mil= 929 miles
Total distance = 1524 miles
Average Speed = 1524 miles / 3 hours
Average Speed = 508 miles / hour

Using the linear best-fit model for the data, what is the predicted running heart rate
of a girl whose walking heart rate is 100 bpm?
Answer:163 bpm
Step-by-step explanation:
The running heart rate of a girl as per linear equation will be 178.7 bpm.
What is a linear equation?Linear equation is an equation where the highest power of a variable is 1.
As per given data,
The average walking heart rate of eight girls is = (66 + 72 + 74 + 78 + 80 + 84 + 86 + 88)/ 8 = 78.5 bpm.
The average running heart rate of eight girls is = (128 + 136 + 134 + 138 + 142 + 144 + 14 8 + 152)/8 = 1122/8 = 140.25 bpm.
Therefore, for walking heart rate of x, the running heart rate will be (140.25/78.5)x = 1.787x.
Hence, the linear equation between walking heart rate and running heart rate is y = 1.787x.
Now, for walking heart rate of 100 bpm of a girl, the running heart rate will be = 1.787 × 100 bpm = 1787.7 bpm.

The graph of a linear relationship passes through (0, 3), and (3, 9). Which is an equation for this linear relationship?
Step-by-step explanation:
1. First calculate for the gradient m
2. Calculate for the constant C by using any point (0,3) or (3,9)
3. Lastly, put the values found in the equation y = mx + c
1. m = Y2-Y1/X2-X1
=9-3/3-0=2
2. input one point together with m into the equation y=mx+c
3=2(0)+C
C=3
3. Therefore equation of linear relationship is
y = 2x + 3
