E is currently at (-5, 1). However, the dilation multiplies the distance between this point and the origin by six, resulting in (-30, 6) as the final coordinates.

Ivy’s father wanted to keep track of the gas he purchased for 3 weeks. He purchased 22.5 gallons during the first week and 19.71 gallons the second week. He forgot to write down his purchases for Week 3. He knows he purchased a total of 61.75 gallons during the 3 weeks. How much gas did Ivy’s father purchase during Week 3? gal

Total amount of gas purchased by Ivy's father in the first week = 22.5 gallons
total amount of gas purchased by Ivy's father in the second week = 19.71 gallons
Let us assume the amount of gas purchased by Ivy's father in the third week = x
The total quantity of gas purchased in 3 weeks by Ivy's father = 61.75 gallons
Then
22.5 + 19.71 + x = 61.75
42.21 + x = 61.75
x = 61.75 - 42.21
   = 19.54 gallons
So 19.54 gallons of gas was bought by Ivy's father in the third week

ANSWER ALL (a-d) FOR 30 POINTS - EASY a. Write an expression for the perimeter a playground using the formula for perimeter. b. The width of a playground is 20 yards more than six times the length. Write an expression for the perimeter using this information. c. Write an equation using the expression from parts a and b. Solve the equation for L. d. If the playground's width is 32 yards, what is the length? NO IMAGE AVAILABLE. PLAYGROUND SHAPE: Rectangle/square.

Part a.

The perimeter formula is: P = 2w + 2L

Your answer for part A is P = 2w + 2L


Part b.

They tell us in part b, that:
w = 6L + 20

Substitute that into what we got for part a.

P = 2(6L + 20) + 2L
P = 12L + 40 + 2L
P = 14L + 40

Your answer for partb is P = 14L + 40


Part c.

So we take what we got from part b, and solve for L.

P = 14L + 40
14L = P - 40

L = \boxed{\frac{P-40}{14}}

That is your answer for part 3 ^


part d.

Plug in w = 32 into what we first got in part b.

w = 6L + 20
32 = 6L + 20
6L = 12

L = 2

Your answer for part d is L = 2

Math help? Easy but I can't get it! :( The distance driven in miles is proportional to the time driven in hours. Ebony drives at a constant rate and plots her progress on a coordinate plane. The point (3, 180) is plotted. At what rate is Ebony driving in miles per hour? A) 40 mph B) 50 mph Eliminate C) 60 mph D) 70 mph

Ok, so, the question states that the distance driven is proportional to the time driven in hours. So, the x value would be hours driven, while the y-value would be the number of miles driven. So, in order to find the speed at which she is driving, you will want to divide the number of miles by the number of hours driving, or 180/3, You answer should be 60, or 60 mph is her speed.

10 PTS, Algebra - Easy Explain which basic moves transform the equation 6x + 2y = 15 into 0 = 15 - 6x - 2y

If you would like to transform the equation 6*x + 2*y = 15 into the equation 0 = 15 - 6*x - 2*y, you have to do two following steps or you can do this at the same time (and you have to do just one step).

First, you have to subtract 6*x from both sides of the equation:
6*x + 2*y = 15   /-6*x
6*x + 2*y - 6*x = 15 - 6*x
2*y = 15 - 6*x

Second, you have to subtract 2*y from both sides of the equation:
2*y = 15 - 6*x   /-2*y
2*y - 2*y = 15 - 6*x - 2*y

The result:
0 = 15 - 6*x - 2*y

Hello! I graduated in 2008 but forgot how to solve multiplication. It's been so long. However I want to be refreshed on solving 44•12

To do this you first have to set this up vertically.
First you multiply through with the 2 (44×2=88). Then next, you have to multiply through with the 1 (44×1=44) But since this is the second line, you have to add the 0 to the end (440).
Now you simply add 88+440=528.

Multiple choice questions were worth some points.
We don't know how many yet.  That's what we're trying to find.
Call it ' M ' (for 'mystery number' or 'multiple-choice')

Francine got 34 multiple choice questions correct.
She got  34M  points for them.
She got  14  more points for her essay.
Her total score was  34M + 14.

Cheryl got 30 multiple choice questions correct.
She got  30M  points for them.
She got  22  more points for her essay.
Her total score was  30M + 22.

THEIR SCORES WERE EQUAL.

So                                               34M + 14  =  30M + 22

Subtract  14  from each side        34M         =  30M + 8

Subtract  30M  from each side:      4M         =             8

Divide each side by  4 :                   M         =             2

Each multiple choice question is worth 2 points.  Exactly.  2.00000

Check: 
Francine got 34 questions right . . . 68 points
plus 14 for her essay  => total 82 .

Cheryl got 30 questions right . . . 60 points

X + 9 = 18 + -2x How do you solve this? And what is the answer? I forgot how to. (11th grade) Thank You.

X + 9 = 18 + -2x

First, simplify 18 + -2x to 18 - 2x / Your problem should look like: x + 9 = 18 - 2x
Second, subtract 9 from both sides. / Your problem should look like: x = 18 - 2x - 9
Third, simplify 18 - 2x - 9 to -2x + 9 / Your problem should look like: x = -2x + 9
Fourth, add 2x to both sides. / Your problem should look like: x + 2x = 9
Fifth, simplify x + 2x to 3x. / Your problem should look like: 3x = 9
Sixth, divide both sides by 3. / Your problem should look like: x =  \frac{9}{3}
Seventh, simplify  \frac{9}{3} to 3. / Your problem should look like: x = 3

Answer: x = 3

QUESTION POSTED AT 04/12/2019 - 09:35 AM

Ok i have two algebra questions 1.) Subtract: (7x^2-x-2)-(-6x^3+3) A.) 6x^3+7x^2-x-5 B.) -6x^3+7x^2-x+1 C.) -x^3-x-5 D.) x^2-x+1 2.) f^2*f^4 A.) (2f)^8 B.) (2f)^6 C.) f^8 D.) f^6 Please explain how you got the last one. I would appreciate it. And i will thank you if its easy to understand :)

Problem A: (7x^2-x-2)-(-6x^3+3)

You can consider the subtraction similiar to a -1(
-6x^3+3). The 1 is implied. So to distribute that negative, we multiply this out.

-6x^3+3 becomes 6x^3 - 3

Our problem is now: 7x^2-x-2 + 6x^3 - 3

Now we add together like items. Let's rearrange for our sanity.

+ 6x^3 + 7x^2 - x - 2 - 3

Simplify: 6x^3 + 7x^2 - x - 5

Unfortionately, outside of factoring or something along those lines, that's as simple as we can get it. So the answer is A.

Problem B: f^2*f^4

Math rules tell us when we multiply the same bases with exponents, we add the exponents together. But the base doesn't change.

4+2 = 6. So: f^6 (D)

That's the easy answer: Math rules say so.

To expand on that specific rule, consider x^2 * x^3. What at the root are these saying? Multiply 2 copies of X, and then multiply 3 copies of x.

We can rewrite this same equation as x*x * x*x*x. 

Remember that since all of these are multiplication, there is no order of operations that needs to be followed.

If we were simplifying that version of the equation, we would write x ^ 5.
