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

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

QUESTION POSTED AT 10/12/2019 - 02:53 PM

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

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**

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.

QUESTION POSTED AT 10/12/2019 - 04:38 AM

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**

First, you have to

6*x + 2*y = 15 /-6*x

2*y = 15 - 6*x

Second, you have to

2*y = 15 - 6*x /-2*y

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.

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 :

Francine got 34 questions right . . . 68 points

plus 14 for her essay => total

Cheryl got 30 questions right . . . 60 points

plus 22 for her essay => total

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

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.
