First solve for y and put it into the y=mx+b form where the slope m=(-1/2) and b=7 and then put it into a graphing calculator or just plug numbers in by hand :)

What value of z makes the equation z+6÷13=4 true?

netineya [11]

Answer:

z = 46/13

Step-by-step explanation:

Step 1: Write equation

z + 6 ÷ 13 = 4

Step 2: Solve for z

Rewrite: z + 6/13 = 4
Subtract 6/13 on both sides; z = 46/13

Step 3: Check

Plug in z to verify it's a solution.

46/13 + 6/13 = 4

52/13 = 4

4 = 4

A 5-lb bag of apples costs 4.50 and an 8-lb bag of the same type of apple costs 7.52. Greg found the unit price which is the con

tester [92]

Answer:

The unit price of 5-lb bag is less than the unit price of 8lb bag.

Step-by-step explanation:

Consider the provided information.

We need to calculate the unite price,

It is given that A 5-lb bag of apples costs 4.50

Calculate the unit price as shown:

$\frac{Cost}{weight} =\frac{4.50}{5}$

We need the cost of 1 l b .

$\frac{Cost}{weight} =\frac{4.50\div5 }{5\div 5}$

$\frac{Cost}{weight} =\frac{0.90}{1}$

So, the cost of 1lb of apple is $0.90.

8-lb bag of the same type of apple costs 7.52.

Calculate the unit price as shown:

$\frac{Cost}{weight} =\frac{7.52}{8}$

We need the cost of 1 l b .

$\frac{Cost}{weight} =\frac{7.52\div8 }{8\div 8}$

$\frac{Cost}{weight} =\frac{0.94}{1}$

So, the cost of 1lb of apple is $0.94.

Therefore, the unit price of 5-lb bag is less than the unit price of 8lb bag.

The product of two natural numbers is 1000. None of them is divisible by 10. Find their sum.

daser333 [38]

Two numbers make up the factors of 1000. In order that neither of the numbers be divisible by ten, each must contain powers of only one of the prime factors of 10, namely, 2 OR 5.

So let's see what we can cook up. The obvious answer is

1000 = 10 * 10 * 10

1000 = 2*5 * 2*5 * 2*5

1000 = 2^3 * 5^3

1000 = 8 * 125 Are there any others?

I don't think so. The answer then comes to 8 + 125 = 133

You might argue that -8 * - 125 would also work. But the question says natural numbers not integers.
