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]

67+k = 83
solve for k
no work needed

Answers

Answer:

k = 16

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

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

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.

Answer:

(C) [tex]h = \frac{2a}{b}[/tex]

Step-by-step explanation:

Here we have the formula for the area of a triangle: [tex]A = \frac{1}{2}bh[/tex]. Our goal is to isolate h on one side of the equation.

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

Multiply both sides by 2:

[tex]2a = bh[/tex]

Divide both sides by [tex]b[/tex]:

[tex]\frac{2a}{b} = h[/tex]

Answer: No Solution

Step-by-step explanation:

When there are absolute values on both sides, you simply just get rid off the signs. (Normally, it results in positive and negative on the other side)

SOLVE:

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

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

This is the answer because:

1) Whenever you are multiplying negative integers, remeber these rules:

Negative x Positive = Negative

Positive x Negative = Negative

Negative x Negative = Positive

Positive x Positive = Positive

2) Since -5 and -8 are both positive numbers, the answer will be a positive product:

5 x 8 = 40

x= 180-127

x= 53

Answer:

63 degrees

Step-by-step explanation:

All angles of a triangle always add up to 180 degrees.

So you take both angles and add them together-55+72=117

You then would take 180 and subtract the total- 180-117=63

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

Hope this helps you

The local coffee house reported losses of -⅜ of their normal profit each day for 3 days. If their normal profit is $350 a day how much money was lost for the 3 days?

Answers

Answer:

Total loss in three days = $393.75

Step-by-step explanation:

Given:

Loss amount = [-3/8] of normal profit

Normal profit per day = $350

Find:

Total loss in three days

Computation:

Total loss in three days = 3 [Normal profit per day][Loss amount]

Total loss in three days = 3 [350][3/8]

Total loss in three days = 3[131.25]

Total loss in three days = $393.75

A small bus charges $3.50 per person for a ride from the train station to a concert. The bus will run if at least 3 people take it, and it cannot fit more than 10 people. Function B gives the amount of money that the bus operator earns when n people ride the bus.

Answers

The minimum amount of money that the operator earns when n people ride the bus is $10.5 and the maximum amount of money that the operator earns when n people ride the bus is $35.

A small bus charges $3.50 per person for a ride from the train station to a concert.

The maximum capacity of the bus to carry the passengers is 10.

The minimum capacity of the bus to carry the passengers is 3.

Function B gives the amount of money that the bus operator earns when n people ride the bus.

Thus the value of 'n' is restricted between 3 to 10.

Therefore,

In general, the amount of money that the operator earns when n people ride the bus is given by the expression.

[tex]\rm{Amount}= \$3.5n[/tex]

The above amount can have minimum and maximum values.

Thus, the minimum amount of money that the operator earns when n people ride the bus is $10.5 and the maximum amount of money that the operator earns when n people ride the bus is $35.
