Can someone help me with my math homework I don't get it and can you please explain how you did it. Also only help me with the highlighter problems...

Answer 1

Answer: 1) What you see as 3 $(3)/(8)$ can be also changed to only a fraction, by changing $(3)/(1)$ to $(24)/(8)$ , but since the question wants 2 as a whole number, we must take out $(24)/(8) = 2 (8)/(8)$ and then add the 8 eights to the other 3, to get $2 (11)/(8)$

for # 10- 13, you need to have the same number on the bottom of all the numbers being subtracted, that means turning the number that aren't fractions (like 4) into fraction, and then into fractions with the same denominators.

10) $(4)/(1)$ changes to $(32)/(8)$ to get $(32)/(8) - (3)/(8) = (29)/(8)$ or $3(5)/(8)$

11) $(5)/(1)$ changes to $(50)/(10)$ , and $2(3)/(10)$ to $(13)/(10)$ to get $(50)/(10)-(13)/(10)=(37)/(10)$ or $3(7)/(10)$

What is the whole number to make statement true ? ÷7 >800

Answers

any whole number above 5600, not counting 5600.

the number 5600 would make them equal, but it needs to be greater than. so any whole number above 5600 would make the statement true:

800(7)= 5600
5600 / 7 = 800
so,
5601 / 7 > 800 is a true statement

again, any whole number above 5600 is a correct answer, there are an infinite amount of solutions

Any whole number or 5600 would work

Line KN represents a proportional relationship. Point N lies at (18,12), as shown on thegraph below.
NO
NA
2 4 6 8 10 12 14 16 18 20
Which ordered pair could represent the coordinates of point K? (2016)
A. (6,0)
B. (2,3)
C. (1.5, 0)
D. (7.5, 5)

Answers

The coordinates of point K in a proportional relationship, we determine the constant of proportionality and multiply is by the x-value to find the y-value. Option B, (2,3), is the correct coordinate pair.

To find the coordinates of point K, we need to determine the constant of proportionality between the x-values and the y-values.

The constant of proportionality is found by dividing the y-value by the x-value at any point on the line. Here, we can choose point N at (18,12).

So, the constant of proportionality is 12/18 = 2/3. To find the y-value of point K, we can multiply the x-value of K by the constant of proportionality: 2/3 * x = y.

Let's check the options. For option A, (6,0), y = 2/3 * 6 = 4.

However, the y-value of point N is 12, so this option is incorrect. Continuing with the same process for options B, C, and D, we find that the only option that satisfies the proportional relationship is option B, (2,3).

#SPJ2

Answer:

D or (7.5, 5)

Step by step explanation:

18 = x

12 = y

(18, 12)

18/7.5

= 2.4

12/5

= 2.4

2.4 = 2.4

The answer is D since its equivalent to (18,12)
