Enter an algebraic expression for the word expression.
twice a number x, minus 20
The expression is

Answer:

Step-by-step explanation:

A = mR - R

R(m - 1) = A

R = A / (m - 1)

x¹ = -2 x² = -8

y¹ = -1 y² = 12

Using midpoint formula,

M = ( x¹ + x²/2 ,y¹ + ý²/2)

or,M ={ -2+(-8)/2 , (-1) +12/2}

or, =( -10/2 , 11/2)

:M = ( -5 , 11/2)

After 5 minutes, the amount of water that has flowed is ...

  (20 gal/min)(5 min) = 100 gal

That amount has flowed out of Tower #1, so it now has ...

  1650 -100 = 1550 . . . gallons in Tower #1

That amount has flowed into Tower #2, so it now has ...

  570 +100 = 670 . . . gallons in Tower #2

Answer:

A-560

B-5600

Step-by-step explanation:

to find the answer for A we need to divide 3360 by 6 which gives us 560.

check: 560 x 6 = 3360

To find the answer for B we need to multiply the answer for A (560) by 10 which gives us 5600

Answer:

A- the question asks the speed and  the speed formula is speed=distance÷time. So 3360÷6=560 mph

B- At this rate means at this constant speed which is 560 mph, how many miles can it travel in 10 hours. We will rearrange the speed formula to find the distance. distance=speed×time. So 560×10=5600 miles.

Answer:

45 degrees

Step-by-step explanation:

Givens

c = 10

opposite = 5√2

Sin(angle) = opposite / hypotenuse

Solution

sin(angle = 5√2 / 10

Sin(angle) = 0.707

angle = sin-1 (0.707)

angle = 45 degrees (rounded. Use a better value for √2)

Answer:

Distribute, then combine like terms, subtract 10 from both sides of the equation, simplify, divide both sides of the equation by the same term, and simplify to get your solution.

Step-by-step explanation:

1.) Distribute

6−2(4−5)=40

6−8+10=40

2.) Combine like terms

6a-8a+10=40

-2a+10=40

3.) Subtract 10 from both sides of the equation

-2a+10=40

-2a+10-10=40-10

4.) Simplify

subtract the numbers

-2a+10-10=40-10

-2a=40-10

subtract the numbers

-2a=40-10

-2a=30

-2a=30

5.) Divide both sides of the equation by the same term

-2a=30

[tex]\frac{-2a}{-2} =\frac{30}{-2}[/tex]

6.) Simplify

cancel terms that are in both the numerator or denominator

[tex]\frac{-2a}{-2} =\frac{30}{-2}[/tex]

a=[tex]\frac{30}{-2}[/tex]

Divide the numbers

a=[tex]\frac{30}{-2}[/tex]

a=-15

a=-15

7.) Solution

a=-15

Simple Interest is defined as the interest that would be accumulated on a particular sum of money, loan, or investment kept or obtained from a financial institution.

The simple interest is $11.24

The formula for simple interest is given as:

I = P x R x T

Where

I = Simple Interest

P = Principal = $800

R = Interest rate = 1.71% = 0.0171

T = Time in years = 300 days

365 days = 1 year

300 days = ?

Cross Multiply

300 days x 1 year / 365 days

= 0.822 year

I = $800 x 0.0171 x 0.822

I = $11.24

Therefore, the simple interest is $11.24

The point which represents the cost of 4 pints is:

                     (4,8)        

Step-by-step explanation:

We are given that:

A market sells strawberries for $2.00 per pint.

Then, cost of 4 pints= $ 4×2.00

                                = $8.00

The point on the x coordinate represents number of pints

and the point on the y coordinate represents the cost in dollars

Hence, the point which represents the cost of 4 pints is:
