Answer:
1, 210.
2. 72 minutes.
3. 42 minutes
4. 2 inches.
5. 3 cents.
Step-by-step explanation:
1. First, divide 240 by 8, which will get you 30, now multiply 30 by 7 and you will get 210 which is your answer.
2. Your keyword here is times. So you know you will multiply. So just multiply 8 and 9, and your product is 72, so 72 minutes.
3. Multiply 3 1/2 by 12, or convert your fraction to a decimal, which in decimal form is 3.50. Your product would be 42.
4. Multiply 1/7 by 14, you should get 14/7, which is an improper fraction. Divide 14 by 7 and you will get 2 inches.
5. So here you have to find the unit rate. Divide the price by the quantity.
4.86/16.2=0.297530865
Round the number up, which would be 3. So it would be 3 cents

Each week, the dimensions of the plot you are responsible to mow changes. The college conducts a lottery, and whichever number is drawn, represents the x value. Your plot has a length which is three more than seven times x and the width is four times x minus 2.
a.) What are the dimensions of your mowing plot? Length: ______________________________________ Width: ______________________________________
b.) What is the area of your plot (remember area = length x width)? Area: _________________________________________

Your neighbor Sally wants to plant flowers around the edge of her circular above ground pool. If the diameter of Sally’s Pool is 18ft, how many flowers will sally need to plant to surround the pool? Round your answer to the nearest hundredth
Answer:
This answer involves finding the circumference of the circle which is basically the length of the entire perimeter of the garden
Step-by-step explanation:
Circumference = 2 * pi * radius
2 * pi * 9 ft = 56 ft
So it depends how many flowers she wants to plant per each foot. If she wants to plant 1 flower per foot the answer is 56 flowers.

Tonya’s class planted sunflowers and the students are tracking the growth of their individual plants. The table shows the height of Tonya’s plant t days after she planted her sunflower seed.
If the growth of the sunflower continues at the same rate, what is the expected height, in inches, on day 55? Show your work or explain your thinking.
Answer:
22 inches
Step-by-step explanation:
22 inches because every 10 days the plant grows by four inches so 10 more days + 5 more days = 4 + 2
Answer:
Step-by-step explanation:t going up by 4 each time (days) so just add 4 from 16 until you get to day 55

Write the point-slope equation of the line that passes through (3,5) and (7,1).
Solve the system of equations..
y=x +45
y= 5x + 13
Answer:
x = 8
y = 53
Step-by-step explanation:
Sub y = x + 45 into the second equation
x + 45 = 5x + 13
Rearrange by collecting the like terms
45 - 13 = 5x - x
32 = 4x
Divide both sides by 4
x = 8
Sub x = 8 into first equation (y = x + 45)
y = 8 + 45
y = 53
If a=6 b=24 what is ab
Answer:
144
Step-by-step explanation:
Since a is 6 and b is 24 we would have to multiply both of those numbers which would give you 144.
Hope this helps and good luck!!
When a = 6 and b = 24, the value of the equation ab will be 144.
What is Algebra?Algebra is the study of mathematical symbols, while logic is the manipulation of those signifiers.
Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction is referred to as the PEMDAS rule. To answer the problem properly and accurately, this rule should be followed.
The expression is given below.
⇒ ab
If the values of "a" and "b" are 6 and 24, respectively. The expression's value is then provided as,
⇒ a × b
⇒ 6 × 24
⇒ 144
When a = 6 and b = 24, the value of the equation ab will be 144.

Answer:
Y=112 x=45
Step-by-step explanation:
y+68=180
so 180-68=112
y=112
y+(4x-2)+30=180
112+(4x-2)+30=180
140+4x=180
-140 to both sides
4x=180
divide by 4 to both sides
x=45
The Y- intercept form from the line whose slope is 2 and passes through (-7,11)
Answer:
y = 2x + 25
Step-by-step explanation:
Slope-Intercept Form: y = mx+b
Slope: m = 2
y = 2x + b
Solve for b:
y = 2x + b
11 = 2(-7) + b
11 = -14 + b
b = 25
y = 2x + 25

2. $294, $150, $175, $450
Step 2 Initial value/y-intercept = /answer options
1. $150, $450, $575, $350
Step 3: Slope intercept form :
y=450x + 575
y=294x + 450
y=150x + 575
y=450x + 150
Answer:
$150, $575, y=150x+575
Step-by-step explanation:
hi! the first answer is $150 because the slope is the change in y values divided by the change in x values.
(1625-1175)/3 = 150
the second answer is $575 because the y-intercept is the y value at x=0. the savings amount increases by 150 every month, so to get to 0, we multiply 150 by 4, which is 600. we subtract this from 1175, which is 575.
the third answer is y=150x+575 because the initial amount (y-intercept) is 575 so it is constant, and it increases by 150 every month (therefore accompanied by a variable).

Solve For v.

Simplify your answer as much as possible.
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The first step you should take is to distribute the 2, so if you do that it'll leave you with... [tex]12=-4v+2v+4[/tex]
Then you notice the like terms and then you have to combine them and that'll give you... [tex]12=-2v+4[/tex]
Now you subtract the 4 to both sides and get... [tex]8=-2v[/tex]
Lastly the fun step is to divide the -2 to both sides and to get the answer of...
[tex]v=-4[/tex]
