8-3x=17 what does x equal
Dima020 [189]

Answer:

x = -3

Step-by-step explanation:

<u>Step 1:  Subtract 8 from both sides</u>

8 - 3x - 8 = 17 - 8

<em>-3x = 9</em>

<em />

<u>Step 2:  Divide both sides by -3</u>

-3x / -3 = 9 / -3

<em>x = -3</em>

<em />

Answer: x = -3

Cups $2
Svetllana [295]

Answer:

$3 from his pockets

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

To begin solving this problem we need to first calculate how much money all the supplies will cost. We do this buy adding up the prices of each individual supply. Like so,

Now we can see that the total amount of the supplies is $13. Since his mom loaned him $10 we can subtract that from the total cost.

Finally, we can see that Juan would need to pay a total of $3 from his pockets to be able to buy all the ingredients.

THE GRAPH IS BELOW THANKS :) Anika is on the crew to set up rides for the state fair. The crew does most of the setup on the day
Vaselesa [24]

Answer:

(a) We will form an equation of line from the points given (6,10) and (2,15)

Using:y-y_1=\frac{y_2-y_1}{x_2-x_1}\cdot (x-x_1)

On substituting the values in the formula above we will get the required equation of line.

y-10=\frac{15-10}{2-6}\cdot (x-6)

\Rightarrow y-10=\frac{5}{-4}\cdot (x-6)

On simplification we will get:

y=\frac{1}{4}(-5x+70)

(b) We need to tell at day 0 put x=0 in above equation:

y=\frac{1}{4}(-5\cdot 0+70)

y=70

Anika worked for 70 hours on the set up crew on the day the fair arrived at the fairgrounds day 0.

Now, we need to tell decrease per day which is equal to the slope of line

To find the slope compare the equation with general equation which is y=mx+c where m is slope

Here, in y=\frac{1}{4}(-5x+70)

m=\frac{-5}{4}  which is the decrease per day.

Solve each proportion​
mamaluj [8]

Hello.

In order to solve a proportion, you should cross-multiply:

\displaystyle\frac{7}{x} =\frac{5}{9}

Multiply 7 times 9 and 5 times x:

5x=63

Divide both sides by 5:

x=\displaystyle\frac{63}{5}

Now let's solve the second proportion.

Multiply 8p times 6 and 12 times 15:

48p=180

Divide both sides by 48:

p=3.75

I hope it helps.

Have an outstanding day.
