Answers

Answer:

w=6

Step-by-step explanation:

First, we want to isolate the variable.

Add 6 on both sides

[tex]\frac{3w+5w}{2} =24[/tex]

Multiply both sides by 2.

3w+5w=48

Combine like terms.

8w=48

Divide both sides by 8.

w=6

I hope this helps!

pls ❤ and give brainliest pls

so you’ll add 3w+5w=8w then multiply the 2 on both side so you cancel the division so 2* 8w/2 -6 =18*2 so youll be left with 8w-6= 36 now youll add 6 to both sides to cancle the subtraction so 8w-6+6=36+6 which will get you to 8w=42 so now you divide the 8 from each side 8w/8=42/8 which will give you the answer which is w= 5.25

Option c is right choice

Hi! The answer is option C. because 4.6 - 6.4 = -1.8 -1.8 - 12 = -13.8 and the expression we are looking for a match to is -13.8 as well so you know we’ve found the answer. The expression we are looking for a matching answer to is -6.4 - 12 = -18.4 + 4.6 = -13.8
It can’t be option A. because it equals -23 and that doesn’t much to the expression we are looking for answer. Option B. can’t be correct either because it equals -1 and that isn’t right either and lastly option D. can’t be right because it equals -10.2. I hope I explained it good enough, Goodluck :)

Find the area of the figure in the image attached. Round to the nearest tenth if necessary.

Answers

Answer:

186 cm²

Step-by-step explanation:

*First we can move the shape around a bit to make it simpler to solve. If we take the triangle from the left side and move it over to the right, it connects with the other piece to create a rectangle. This leave two rectangles total which is much easier to solve.

*To find the length of the right rectangle, you take the 22 cm at the bottom and subtract the 12 cm (which is being used as the length for the left rectangle). This will give you a length of 10 cm long.

Left rectangle:

A = lh

A = 12 (8)

A = 96 cm²

Right rectangle:

A = lh

A = 10 (9)

A = 90 cm²

Total:

A = 90 + 96

A = 186 cm²

186cm 12 x 8 x 9 x 22

Step 1: you have to replace y with x-6 to make it all one equation (as seen in the picture below)

Step 2: write it all together so: x-6= -2x+3

Step 3: add 2x on both sides to cancel out the negative so: x+ 2x and -2x+2x

Step 4: add 6 on both sides to cancel out the negative so: -6+ 6 and 3+6

Steve buys a wallet that costs $35.00. He pays 10% sales tax. How much does he pay for the wallet with tax?

A. $48.50
B. $38.50
C. $18.50
D. $45.50

Answers

Answer:

B. $38.50

Step-by-step explanation:

The original price of item (before tax) is 100% of the price of the item since 100% means the whole amount.

The tax is 10% of the original price, so add 10% to 100% making it 110%.

The total price including tax is 110% of the original price.

We need to find 110% of $35.00.

To find a percent of a number, multiply the percent by the number.

110% of $35.00 = 110% * $35.00

Change the percent to a decimal by moving the decimal point two places to the left.

110% becomes 1.10 as a decimal

110% of $35.00 = 110% * $35.00 = 1.10 * $35.00 = $38.50

Answer: B. $38.50

B, because you take the 10% and you turn the percent into the decimal by move it to the right two times so then it will look like this .10 after you take that and divide by 35 which will give you $3.50 which is the tax and then you add that to your amount and you have $38.50

Find the area of the figure in the image attached. Round to the nearest tenth if necessary.

Answers

Answer:

The area of the figure shown is 37.5cm^2, or 37 1/2cm^2, depending on what it wants from you.

Step-by-step explanation:

Break the shape into a triangle with measurements of 2.5, and 6.

And then the Rectangle with measurements of 6, and 5.

area of a rectangle is w*l so 6*5=30in

Area of a triangle is b*h*1/2 or b*h divided by 2 (either way both are the same, chose what makes you comfortable, I will use the first one.),

2.5*6*1/2

2.5*6=15

15*1/2=7 1/2cm or as a decimal 7.5cm

Now add the two for the full area, 30+7.5=37.5cm

Find the difference between the first and second points.

Since the x-coordinates are the ones changing, find the difference between them.

2 - (-3)

= 5

Then find the distance between the second and the third points.

Here, the y coordinates are the only ones changing, so we subtract them/or find the distance between them.

2-(-5)

Now add the distances (5+7) and you get 12.

From -2<x<-1, the function F(X) is increasing. (B)

Really, it increases all from around -2.5<x<0.5

C is also the second answer, as it increases til around 2.5

It is decreasing from -4<x<-3. But increases right after. It then starts to slow down around x = 1 and go down again.

Which means (B) is your answer.

If you want to get fancy, its a polynomial and if you take the derivative for instantaneous rate, you will see f prime is increasing if you make an example function.
