My mental health hasn’t really been great lately and that has been affecting how I have been doing with school work, and I’m finding math the hardest right now and I would really appreciate it if someone would help me with question 2,3,4 and 5. I know that’s a lot and ofc you don’t have to answer all of them, it would just mean a lot if you could help me with the questions. Thanks so much!

Answer:

5 square 10 yards

$40

Step-by-step explanation:

Mario:

20 + 4x

Her competitor:

10 + 6x

Where,

x = number of 10 square yards

Equate the expressions

20 + 4x = 10 + 6x

Collect like terms

20 - 10 = 6x - 4x

10 =2x

Divide both sides by 2

x = 10 / 2

= 5

x = 5 square 10 yards.

Charge at that moment

Using any of the cost equation

10 + 6x

= 10 + 6(5)

= 10 + 30

= 40

$40

Or

20 + 4x

= 20 + 4(5)

= 20 + 20

= $40

Answer:

7 feet

Step-by-step explanation:

Length of one piece of string = 28 feet.

Length of the second string = 42 feet.

Since the number of required pieces was not given but many are required, the greatest length can be determined by;

If the maximum length is 7 feet, then:

the number of pieces from 28 feet long string = [tex]\frac{28}{7}[/tex]

                                                      = 4

Also,

the number of pieces from the 42 feet lone string = [tex]\frac{42}{7}[/tex]

                                                    = 6

Total number of 7 feet strings that she can make = 4 + 6

                                                    = 10

Since many pieces are required, the greatest length she can make is 7 feet. If she increase the length to 14 feet, the number of pieces would be 5 which limit the required number.

Answer:

alright so you got 2 points! now this is the slope formula! y2-y1/x2-x1

okay let's label your points! (x1 0,y1 -3) (x2 2,y2 1)

let's follow the formula this makes it so we can solve! 1--3/2-0

I understand you may get a decimal but don't use 2.5 use a fraction because teachers seem to like fractions and general decimals can be hard to use (experience lol) 2.5 is 5/2 so this means your slope is 5/2

this formula works every single time and if you memorize it you can do any other problems with 2 points! please memorize y2-y1/x2-x1

Answer:

9.5 feet

Step-by-step explanation:

To calculate volume, the formula is V = l*w*h.

We have the volume, length, and height, so we just need to plug it in to find the width. 256.5 = 4.5*w*6. Calculate this, and it'll become 256.5 = 27w. Then we divide both sides by 27 to find w. 256.5/27 = 27w/27. 9.5 = w. Width is 9.5 feet.

Answer:

There is 1 tree per 1.6 acre.

Step-by-step explanation:

Divide the number of trees from the number of acres. This will tell you how many acres are between each tree.

Answer:

0.6 acres.

Step-by-step explanation:

You divide the total population of the willow tree (30) by the areas they occupy (50 acres). Therefore, 30/50=0.6 population per acre.

Answer:

2.25

Step-by-step explanation:

When finding these types of equations out you need to turn the percent into a decimal and then multiply it by the number. After getting your answer from that add it to the original number and that is how these types of equations works.

The new cost of gas for a gallon is $2.25

A relative value indicating hundredth parts of any quantity. One percent (symbolized 1%) is a hundredth part.

Given that, one year ago gas was $1.80 per gallon, the following year gas increased by 25%.

The previous cost of gas = $1.80

Cost is increased by = 25%

Therefore, new cost will be = 125% of $1.80

= 125 / 100 × 1.80

= 225 / 100

= 2.25

Hence, the new cost of gas for a gallon is $2.25

Answer:

slope = 9 y-intercept = -5/2

Step-by-step explanation:

since slope form is y=mx+b we know that m= slope and b=y-intercept. since 9 is in place of the m that shows that 9 is the slope. since 5/2 is in the b place you would think the y-intercept would be 5/2 but since the equation is - 5/2 instead of + 5/2 it would be + (-5/2) making the y-intercept negative. hope this helped. :)

Answer:

the 3rd 4th and 5th answers are true

Step-by-step explanation:

just substitute the points into the equations.

first equation, substitute the points 2,8 into the equation.  2 + 2(8) = 20.

2 + 16 = 20

18 = 20 is not a true statement.

second equation, substitute the points -1,5 into the equation.  -1 + 2(5) = 10.

-1 + 10 = 10

9 = 10 is not a true statement.

third equation, substitute the points 7,7 into the equation. 2(7) - 7 = 7.

14 - 7 = 7

7 = 7 is a true statement.

fourth equation, substitute the points 7,-7 into the equation. 3(7) + -7 = 14.

21 + -7 = 14

14 = 14 is a true statement.

fifth equation, substitute the points 1, 1 into the equation. 2(1) + 6(1)  = 8.

2 + 6  = 8

8 = 8 is a true statement.

Answer:

The image of (0, -6) after the same transformation is (-6, -12)

Step-by-step explanation:

After the required translation, the given image of the given point P(3, 8) is P'(-3, 2)

Therefore, the translation of preimage P(3, 8) to the image P'(-3, 2) is given by the difference between the coordinates as follows;

The translation from P(3, 8) to P'(-3, 2) = T(-3 - 3, 2 - 8) = T(-6, -6)

Therefore after the same translation, the preimage of (0, -6) will have an image given as follows;

Coordinate of preimage (0, -6) → T(-6, -6) (0, -6) = (0+ -6, -6 + -6) → Coordinate of image (-6, -12)

The image of (0, -6) after the same transformation = (-6, -12).
