Answer: x = -8 or x = 2

Step-by-step explanation: Follow your rule for solving absolute value equations. Since the absolute value is isolated on one side of the equation, we can split the problem up into two separate equations.

The first equation will be identical to the original except it won't have the absolute value signs which are the vertical bars.

In this case, that equation is x + 5 = -3.

The second equation will look like the first, only the right side will be changed to a positive. So in this case, that equation is x + 5 = 3.

Now simply solve each equation to get x = -8 or x = -2.

You can check both of these answers by plugging them back in for x in the original problem and you will see that they both work.

Answer: this equation is false

which would be x= undefined

Jesse takes his dog and cat for their annual vet visit. Jesse's dog weighs 23 pounds. The vet tells him his cats weight is 5/8 as his dogs weight. How much does his cat weigh?

Answers

14³/₈ or 14.375 pounds.

Further explanation

Given:

Jesse takes his dog and cat for their annual vet visit.
Jesse's dog weighs 23 pounds.

The vet tells him his cat's weight is ⁵/₈ as his dog's weight.

Question:

How much does his cat weigh?

The Process:

Since the vet tells him his cat's weight is part of his dog's weight by ⁵/₈ part, let us create an 8-unit pattern that represents the dog's weight.

Jesse's dog weight in the pattern: $\boxed{ \cdot }\boxed{ \cdot }\boxed{ \cdot }\boxed{ \cdot }\boxed{ \cdot }\boxed{ \cdot }\boxed{ \cdot }\boxed{ \cdot } \rightarrow 23 \ pounds$
Jesse's cat weight in the pattern: $\boxed{ \cdot }\boxed{ \cdot }\boxed{ \cdot }\boxed{ \cdot }\boxed{ \cdot } \rightarrow (5)/(8) \ of \ 23 \ pounds$

And now, let us find out the cat's weight. As we know, the cats' weight is ⁵/₈ the dog's weight.

The cat's weight:

$\boxed{ \ = (5)/(8) * 23 \ }$

$\boxed{ \ = (5 * 23)/(8) \ }$

Recall this $\boxed{ \ 5 * (20 + 3) = (5 * 20) + (5 * 3) = 100 + 15 = 115 \ }$

$\boxed{ \ = (115)/(8) \ }$

Recall this $\boxed{ \ 115 / 8 = (14 * 8) + 3 \ }$

$\boxed{ \ = 14(3)/(8) \ }$ as a mixed fraction

$\boxed{ \ = 14(3 * 125)/(8 * 125) = 14(375)/(1,000) = 14.375 \ }$ as a decimal fraction

Thus, his cat weigh is $\boxed{ \ 14(3)/(8) \ or \ 14.375 \ pounds \ }$

If B1 = 3 m and B2 = 4m and the area is 7 m squared, what is the height?

Answers

the height is 1, because it's A=(b1 + b2)*h, the equation is this now 7=3 + 4)*h, you add 3 + 4 then that will give you 7, so now it should look like this 7=7*h, you do a fraction line under the 7 and 7*h each, and put a 7 as the denominator, so it kind of looks like this now 7 = 7*h
__ __
7 7 then you cancel the 7*h which leaves you to just h, so 7 divided by 7 will give you 1 so it looks like 1=h, PHEW

Lisa, an experienced shipping clerk, can fill a certain order in 10 hours. Tom, a new clerk, needs 13 hours to do the Thesame job. Working together, how long will it take them to fill the order?
(Sin

Answers

It takes 6 hoursto complete the work for both Lisa and Tom working together.

Step-by-step explanation:

step 1 :

Let us assume that,

Total work = 130 units (take a number that can be divisible by both 10 and 13)

step 2 :

Lisa completes the work in 10 hours.

Lisa's work per hour=total work / time taken to complete the work

= 130 / 10 = 13 units per hour

step 3 :

Tom completes the work in 13 hours.

Tom's work per hour =total work / time taken to complete the work

= 130 / 13 = 10 units per hour

step 4 :

Both Lisa and Tom can work per hour = 13 units + 10 units

= 23 units per hour

step 5 :

Working together can complete the total work in = total work / time taken to complete the work together

= 130 units / 23 units per hour = 5.65 (which is approximately 6 hours).

∴ Time taken by working together = 6 hours.

Answers

Answer:

The student multiplied by 12 on the left and divided by 12 on the right

Step-by-step explanation:

24 = c/12

We can rearrange the and flip the left and right side

c/12 =24

Multiply both sides by 12

12* (c/12) = 24*12

c = 288

The student multiplied by 12 on the left and divided by 12 on the right
