Answer:

Step-by-step explanation:

In this problem we need to kind of write the picture into an equation so the first thing we see are 4 xs on the far left-hand side this is representing "4x" then we see 5 - blocks on the right which represents "-5" because we have 5 minuses then on the other side we see 7 + blocks which represent just "7". After we identify everything in the picture we can write an equation so 4x -5 = 7. Then we solve so we need to separate x on one side and all the other numbers to the other to do that we can move the -5 to the side the 7 is on and because of math when we move a number to another side of the equation we have to switch the sign it has so if it was -5 then on the other side it would be 5 then we add 7 to 5 which would equal 12. Then we are left with 4x = 12 and to keep x on its own side we need to divide 4 from the other side because it is  multiplying on the x side and again we need to switch the sign. then we are left with x=3. Hope this helps!

Hey Mate...

Step-by-step explanation:

All that the slope-intercept form (the equation to describe linear equations) is, is an equation (y=mx+b) where m (the number that multiples x) is the slope and b (the number that is not multiplying a variable on the right-hand side of the equation) is the y-intercept.

Answer:

7.92 cm^3

Step-by-step explanation:

To find volume all you have to do is multiply the length, width, and height. The answer would be: l * w * h = 2.2 * 2 * 1.8 = 7.92 cm^3.

Answer:

81 cubic foot

Step-by-step explanation:

It is given that the box is packed with cubes whose side is 1 foot. So the volume of one cube is 1 cubic foot.

Now from the figure, we can see that :

Number of cubes fitting the box across its length = 9 cubes

Number of cubes fitting the box across its width = 3 cubes

Number of cubes fitting the box across its height = 3 cubes

And each of these cubes measures 1 x 1 x 1 cubic foot

So the volume of the box can be found out by:

Volume = length x width x height

             = 9 x 3 x 3

             = 81 cubic foot

Therefore volume of the box is 81 cubic foot.

Answer:

10

Step-by-step explanation:

Im guessing since you have to estimate it then u have to round them up. So if you move both of their points by 2 spaces (divide both by 100) They will be 221x510.

Round them up to 200x500.

That woule be 100 000. Then at the end just dont forget to divide by 10000.

Answer:

3/5 of her time

Step-by-step explanation:

She spent 30 minutes out of 50 minutes on her math assignment. So, we can write this fraction:

30 minutes / 50 minutes

Divide both the numerator (top of the fraction) and denominator (bottom of the fraction) by 10 minutes to get

3 / 5

So, the answer is 3/5 of her time.

Answer:

$44

Step-by-step explanation:

Hello!

It said that 7 cameras cost $308, right?

If each camera costs the same, it means that 7 cameras with the same value equal $308.
If we use this in an equation, and if x is a variable we want to solve, it would be:

7x = 308.

If 7x = 308, it would be

308/7 =

44.

So, $44 is the answer.

Step-by-step explanation:

The shortest distance Estelle swam at practice is 200 meters if the Estelle swims for the Shorewood Sharks swim team

A box and whisker plot is a method of abstracting a set of data that is approximated using an interval scale. It's also known as a box plot. These are primarily used to interpret data.

We have box plot data:

1,000    1,400    1,800    2,200    2,600    3,000

From the box plot:

The shortest distance Estelle swam at practice is given by:

= 1800—(1400+1800)/2

= 1800 – 1600

= 200 meter

Thus, the shortest distance Estelle swam at practice is 200 meters if the Estelle swims for the Shorewood Sharks swim team

Answer:

  (b)  y = (x +4)² -1

Step-by-step explanation:

The vertex form of the equation of a parabola is ...

  y = a(x -h)² +k . . . . . . . . . vertex (h, k); scale factor 'a'

The graph shows the vertex is (h, k) = (-4, -1) and a=1. Putting these values into the form, we have ...

  y =(x +4)² -1

Answer:

$6510

Step-by-step explanation:

First thing that should come to mind is: What is 7% of $7000?

Well, if you don't know how to find a percent of something, this is the formula you use:

7000 x 0.07 = 490.

In the first year, they will receive 490 out of the 7000 they've invested.

7000 - 490 = 6510.

Therefore, the account balance at the end of the first year will be 6510.

The account balance at the end of first year will be equal to $6510.

What do you mean by percentage ?

Percentage is the relative value indicating one hundredth part of any quantity.

It is given that a retiree invests $7000 in a savings plan which pays 7% per year.  So , it meant that we need to calculate that what is the value 7% of $7000.

So , 7% of $7000 is :

= 7000 × [tex]\frac{7}{100}[/tex]

= $490

It is known that this amount is paid as per plan per year. So, to find out the account balance at the end of the first year , we need to subtract the invested amount to the amount per year at 7%.

So , the account balance at the end of first year will be :

= 7000 - 490

= $6510

Therefore , the account balance at the end of first year will be equal to $6510.

Answer:

We know that for a human body 9.3% of its total mass is hydrogen.

Now we have a person with a mass of 140 lb.

Then we have that the 100% of the mass is 140lb, the 9.3% of this is hydrogen.

We can write:

9.3% = X

100% = 140lb

We want to find the value of X (mass of hydrogen)

Then we can take the quotient of these two equations to get:

(9.3%/100%) = X/140lb

Now we can isolate the variable X to get:

(9.3%/100%)*140lb = X = 13.02 lb

So this person has about 13.02 lb of hydrogen in his/hers body.

The total cost of the car purchase, including the base price, freight charge, air conditioner cost, and license-related fees, is $68,937.

To calculate the total cost of the car purchase, we need to consider the base price of the car, the charge for freight, and the additional costs for the air conditioner and license-related fees.

Given:

Base price of the car: $64,987

Freight charge: $2,300

Additional costs:

Air conditioner cost: Let's assume it's $500 (not explicitly mentioned in the given information)

License-related fees: Let's assume it's $150 (not explicitly mentioned in the given information)

To calculate the total cost, we add up all the costs involved:

Total cost = Base price + Freight charge + Air conditioner cost + License-related fees

Total cost = $64,987 + $2,300 + $500 + $150

Total cost = $68,937
