Answers

[tex]\frac{3}{1}[/tex]Answer:

Step-by-step explanation:

3x-y = 2

2x+y =4

put them into slope intercept form

y=3x-2

y=-2x+4

Now, you can either graph it or use substitution

3x-2 = -2x+4

+2x +2x

5x -2 = 4

+2 +2

5x = 6

5x/5 = 6/5

x = 6/5

3x -2 = y

3(6/5) -2 = y

3 x 6 / 1 x 5 = 18/5

3 3/5 -2 = 1 3/5

Let me know if it's wrong.

Evaluate 2x + xy + 2-3 for x=-9, y=-5, and
z=-3.

Answers

Hi! Keep in mind there is no z in the equation so the question might trick you!

The answer is 26

Here is the process:

1. Replace the variables with the numbers they gave you.

2(-9)+ (-9)(-5)+ 2-3

2. Next evaluate it. I got 45 because a negative multiplied by a negative makes a positive.

* PEMDAS states you addition and then subtraction but it could vary based on the equation.

In this equation you have to do addition first.

-18+ 45+2-3

27+2-3

make f the subject of the formula c=[tex]\frac{5(f-32)}{9}[/tex]

Answers

Answer:

[tex]f=\frac{9c}{5}+32[/tex]

Step-by-step explanation:

[tex]c=\frac{5\left(f-32\right)}{9}[/tex]

Switch sides:

[tex]\frac{5\left(f-32\right)}{9}=c[/tex]

Multiply both sides by 9:

[tex]\frac{9\times5\left(f-32\right)}{9}=9c[/tex]

[tex]5\left(f-32\right)=9c[/tex]

Divide both sides by 5:

[tex]\frac{5\left(f-32\right)}{5}=\frac{9c}{5}[/tex]

[tex]f-32=\frac{9c}{5}[/tex]

Add 32 to both sides:

[tex]f-32+32=\frac{9c}{5}+32[/tex]

[tex]f=\frac{9c}{5}+32[/tex]

3 things to keep 1: It takes a garage owner 45 minutes to travel between his two garages 60 miles apart.

To make lemonade , Kate uses 1 cup of lemon juice and 2 cups of sugar. If she makes a larger amount of lemonade with 10 cups of sugar, how many cups of lemon juice does she need?

Answers

Answer:

5 cups

Step-by-step explanation:

Answer:

1/2 : 1

2 : 4

3 : 6

Notice that every ratio consists of a number and double the number.

For 1/2 cup lemon juice, use 1 cup sugar.

The amount of sugar is twice the amount of lemon juice.

The ratio is 1:2

Since you are told the ratio is 1:r, that means r is 2.

The unit rate is 2 cups sugar per cup of lemon juice.

To do this, let’s treat the rest of the equation as if there were no variables.

George put 25 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 45 mL. What is the volume of the object?

Answers

Answer: 20 mL

Step-by-step explanation:

According to Archimedes, the upward force exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces.

i.e. weight of the object = weight of the fluid displayed

Given: George put 25 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 45 mL.

So, the volume of the object = New volume - Original volume

= 45 mL - 25 mL

= 20 mL

Hence, the volume of the object =20 mL

Answer:

Step-by-step explanation:

Isolate the variable, k. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS is the order of operation, and =

Parenthesis

Subtract 67 from both sides of the equation:

k + 67 = 83

k + 67 (-67) = 83 (-67)

k = 83 - 67

k = 16

16 is your answer for k.

What is the value of y in the equation 5x + 2y = 20, when x = 0.3?

Answers

Answer:

9.25

Step-by-step explanation:

5(0.3) = 1.5

20-1.5=18.5

18.5÷2=9.25

Answer:

y = 9.25

Step-by-step explanation:

5x + 2y = 20

when x = 0.3 we have

5(0.3) + 2y = 20

1.5 + 2y = 20

Using the subtraction property subtract 1.5 from both sides of the equation

That's

1.5 - 1.5 + 2y = 20 - 1.5

2y = 18.5

Divide both sides by 2

[tex] \frac{2y}{2} = \frac{18.5}{2} [/tex]

We have the final answer as

y = 9.25

Donis bought a t-shirt for $15 and jeans for $35.50. If the sales tax rate is 8.25%. What is the sales tax for the t-shirt and jeans in dollars and cents? *

Answers

Answer: 4 dollars and 17 centsThis is the same as saying $4.17

====================================================

Explanation:

15+35.50 = 50.50 dollars is the total before tax is applied.

Take 8.25% of this to get

0.0825*50.50 = 4.16625

and this rounds to 4.17, which is the amount of sales tax charged.

$4.17 = 4 dollars + 17 cents

---------

Extra info:

The grand total will be 50.50+4.17 = 54.67

Another way to get the grand total is to multiply 1.0825 by the previous subtotal (50.50) getting 50.50*1.0825 = 54.66625 and that rounds to 54.67

The multiplier 1.0825 effectively means "increase by 8.25%"
