Answer:

im pretty sure its -2x but i might be wrong

Step-by-step explanation:

Answer:

x = 3

Step-by-step explanation:

Distributive property: a(b + c) = (a*b) + (a*c)

3(2x - 4) = 3x - 3

3*2x - 3*4 = 3x - 3

6x  - 12 = 3x - 3           {Add 12 to both sides}

6x -12 + 12 = 3x -3 + 12

          6x   = 3x + 9       {subtract 3x from both side}

     6x - 3x = 3x - 3x + 9

          3x   = 9      {Divide both sides by 3}

         3x/3 = 9/3

x = 3

Answer:

4 = dt

I hope this helps

Sorry if it's wrong

Answer:

y = 5x - 8

Step-by-step explanation:

The linear equation in slope intercept form :

y = mx + c

m = slope ; c = intercept

m = Rise / Run = (y2 - y1) / (x2 - x 1)

Rise = (y2 - y1) = (12 - (-8)) = (12 + 8) = 20

Run = (x2 - x1) = (4 - 0) = 4

Slope, m = Rise / Run = 20 /4 = 5

Hence,

y = 5x + c

For the points ; y = 12 ; x = 4 ; we could obtain c

12 = 5(4) + c

12 = 20 + c

12 - 20 = c

-8 = c

The equation becomes :

y = 5x - 8

Answer:

140 - 6(8)

140-48

140-48= 92

92 is your final answer.

Answer: what is R equal to?

what is this for

Step-by-step explanation:

A cuboid with side lengths x, x and h has a surface area of

S=2x2+4xh.

We know that the total surface area should be 150cm2, so

150⟹150−2x2⟹h=2x2+4xh=4xh=75−x22x.

Answer:

5 weeks

Step-by-step explanation:

First, solve for the total cost of the game console after tax and a coupon

Solve for tax:

$250 × 8.25%

Convert percentage into a decimal

250 × 0.0825

20.625

Round up to nearest hundredths place (because the unit is dollars)

20.63

Add this tax onto the original cost

250 + 20.63

270.63

Subtract the coupon from the total

270.63 - 10

260.63

Total cost is $260.63

Now let's find how much Kade needs to save so set up an equation

Variable x = number of weeks

45 + 45x = 260.63

Subtract 45 from both sides to isolate the variable

45x = 215.63

Divide both sides by 45

x = 4.791777...

Round up to nearest whole number (because units are weeks)

x = 5 weeks

Answer:

15/100 x 35 = $5.25

Of means multiplication

Always consider a percent as a fraction but it has to be out of 100.

A way to remember that is that the word "cent" means 100. So you multiply the two numbers (divide at the end 21/4 = 5.25)

Answer:

1. it is 7 cm long

2. it is a chord

3. it is the diameter of the circle

Step-by-step explanation:

Here, we want to select three statements that are true about CB

From what we have, CB runs from one edge to the other, passing through the center of the circle

Also, as we can see, AD is a radius as it is the distance from the center of the circle to the circumference; CB is twice this as it is the diameter

The diameter is a chord that passes through the center of the circle and it is a radius

So let us select the correct statements;

1. it is 7 cm long

2. it is a chord

3. it is the diameter of the circle

Answer:

Calculation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year,

then, solving our equation

I = Prt (Where p=principle,r=rate,t=time)

I = p*0.08*1=0.08p

Step-by-step explanation:

Bo should multiply his current amount by 1.08 to get the complete balance in one step.

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

We have been given that Bo invests money in an account paying a simple interest of 8% per year.

To find the total balance in a year, you can use the formula:

balance after 1 year = balance × (1 + (interest rate/100))

In this case, the interest rate is 8%, so you can use the formula like this:

balance after 1 year = balance × (1 + (8/100))

This simplifies to:

balance after 1 year = balance × 1.08

Therefore, to find the total balance in one step, Bo should multiply his current balance by 1.08.

Answer:

Step-by-step explanation:

This is because

tan(angle) = opposite/adjacent

For the reference angle 38, we have 10 as the opposite side and x as the adjacent side.

Therefore, tan(38) = opposite/adjacent = 10/x

Side note: if you solve for x, you should get roughly x = 12.799

Answer: C for sure
