Answer:
A
Step-by-step explanation:
use the equation x=4+y/3 to find out.
8x + 2y = 24
2y = -8x + 24
y = -4x + 12.....so the slope is -4, and the y int is 12 or (0,12)
to find the x int, sub in 0 for y and solve for x....in either the original equation or the slope intercept equation
8x + 2y = 24
8x + 2(0) = 24
8x = 24
x = 24/8
x = 3.....so the x int is 3 or (3,0)
now plot ur intercepts (3,0) and (0,12)......now start at ur y int (0,12)...and since ur slope is -4, u come down 4 spaces, then to the right 1 space, then down 4, and to the right 1...keep doing this and u should cross the x axis at (3,0)

You have made a poster that is 4 feet by 5 feet to hang on a wall, you want to use the reaming 10 sqaure feet of fabric to add a decorative border width. What should the width of the border be
Answer:
0.556 foot wide or 6 ²/₃ inches wide
Step-by-step explanation:
first we must calculate the total perimeter of the poster that will be decorated with the fabric:
the total perimeter of the poster = 4 + 4 + 5 + 5 = 18 feet long
you have 10 square feet of fabric, so its width should be 10 / 18 = 0.556 foot wide or 6 ²/₃ inches wide

Step-by-step explanation:
A school has 100 students. on friday, 70 students went on a field trip. what percent of the students did not go on the field trip
Using percentages we know that 30% of students did not go on the field trip.
What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means.So, the percentage of children that did not go to school:
The total number of students is 100.Students that went on the trip are 70.Students that did not go:
100 - 70 = 30 students30 students are % of 100:
30/100 × 100.30 × 10030%Therefore, using percentages we know that 30% of students did not go on the field trip.

A parallelogram has sides 8 ft and 14 ft the height corresponding to the 14 ft base is 4 ft what is the height corresponding to the 8 ft base
Given :
A parallelogram has sides 8 ft and 14 ft the height corresponding to the 14 ft base is 4 ft.
To Find :
The height corresponding to the 8 ft base.
Solution :
Since, both parallelogram are similar. So, ratio of the sides of parallelogram is similar in both the cases.
[tex]\dfrac{h_1}{h_2}=\dfrac{b_1}{b_2}\\\\\dfrac{8}{14}=\dfrac{h_1}{4}\\\\h_1 = \dfrac{8\times 4}{14}\\\\h_1 = 2.285 \ ft[/tex]
Therefore, the height corresponding to the 8 ft base parallelogram is 2.285 ft.

wants to reach 18 feet up the side of his
house. To the nearest foot, how far from the
base of the house should he place the
ladder?
Answer:
8 ft
Step-by-step explanation:
the ladder will make a right angle triangle with the house. The hypotenuse of the triangle is the ladder, 20 ft, and the height of the triagnle is 18 ft.
Solve for the base of the right angle triangle using pythagorean's theorem:
c=20, a=18, b=?
[tex]b^{2}=c^{2} - a^{2}\\b^{2}=20^{2} - 18^{2}[/tex]

Jordan makes two batches of cookies each week for her book club. Each batch of cookies needs 1 2/3 cups of flour. If she starts with 16 1/2 cups of flour, for how many weeks can she make cookies? Explain your solution.
Answer:
She can make cookies for 4.95 weeks
Step-by-step explanation:
2 x 1 2/3 = 3.333333333
16.5/ 3.333333333 = 4.95
Since Jordan is making two batches of Cookies per week, you need to multiply 2 by the amount of resources needed to bake one batch of cookies. So you multiply 1 and 2/3 by 2 to get the amount of resources neccesary for one week of making cookies. Then, you take the full amount of resources that she has, and divide that by the amount she uses per week, that number will give you the number needed to figure out how many weeks she has to bake cookies.
To figure out the number that is being divided to get the whole number in weeks, you would take the 16.5 cups of flour. The reason why this is, is because that Is the starting number of cups that she has. So here you would need to divide the amount you are taking from it each week. This will result in the amount of weeks that she is able to bake cookies with her flour.
A small container of detergent holds 75% as much as the large container of detergent. If the small container hold 36 ounces, the large container will hold ounces.
Answer:
48 ounces
Step-by-step explanation:
Let the amount in small container be x and that of largest be y
If a small container of detergent holds 75% as much as the large container of detergent, this can be represented as;
x = 75% of y
Given x = 36
36 = 75% of y
36 = 0.75y
y = 36/0.75
y = 48 ounces
Hence the large container will hold 48 ounces

Find the probability of drawing two diamonds in a row from a standard deck of 52 cards. After the first card is drawn it is set aside and not returned to the deck.
Answer: 1/17
Step-by-step explanation:
First and foremost, we should note that there are 13 diamonds in a standard deck of 52 cards.
If the first card is drawn, the probability of picking a diamond is 13/52. Since it's not replaced, when another one is picked, the probability that it will be diamond will be 12/51.
We then multiply both together. This will be:
= 13/52 × 12/51
= 1/4 × 4/17
= 1/17
