Darius is saving money to go to a gaming summer camp. He already has $95 in the bank. His goal is to earn $900 so he can pay for

ruslelena [56]

Answer:

95+35x=900

23 weeks

$48 per week

I would recommend looking at work, it will help the answers make more sense.

Step-by-step explanation:

Starting with the equation. You can see that he makes 35 dollars per week he works. Since we don't know the amount of time he works, we can use a variable. I'm going to use x. Since Darius already has $95 in his bank account, we need to make sure to include this money into the trip. So, the equation would look something like this. 95+35x=900

Let's find out how many weeks it will take Darius to reach his goal $900. First we need to subtract 95 from both sides. So, 95-95, which will cancel out, and you should be left with 35x=900-95. Now, 900-95. If you aren't good with subtracting, round 95 to 100. Now you get 800, make sure to add back the five. You should result in 805. So you are left with getting x alone.

35x=805

Divide each side by 35, so we can get x alone. 35 divided by 35 will cancel out, since it equals one. One is assumed, so you can just put x. Now it's time to divide 805 by 35. You should get 23. So that's your answer. It should take 23 weeks before Darius can pay to go to summer camp.

Since Darius wants to complete his goal six weeks earlier, he would need to be payed a different amount. The amount in his bank account won't change, nor will the amount of what we need to pay for this summer camp. So, let's rewrite the equation.

95+48x=900

Since it doesn't end up being a whole number when dividing, you can see that he might end up with extra change.

Solve like before and you should get 17. Which to check, you will see that 23-6=17.

95-95+48x=900-95

48x=805

48(17)=816

Add 95 to 816

911

Darius will not only meet his goal, but will also have extra money left over.

So, Darius needs to earn $48 per week.

I need help if you do it you can have brainest

Ne4ueva [31]

9514 1404 393

Answer:

see below

Step-by-step explanation:

Starting from the point-slope equation ...

y -y1 = m(x -x1)

Solving for y gives ...

y = mx +(y1 -m·x1)

So, the slope-intercept form equation is fairly easily found:

y = mx +b . . . . where m = m, and b = y1-m·x1

This is the equation we have used for 'b' in the attached spreadsheet.

Of course, the formula for slope is ...

m = (y2 -y1)/(x2 -x1)

This is the equation we have used for 'm' in the attached spreadsheet. For all problems, we have used the first point. (It doesn't matter which point you use if there are two of them.)

The second attachment is the Google Sheets spreadsheet saved in ODS format. Most spreadsheet programs should be able to open that so you can see the formulas, if you're interested. (The gray values of m are computed using the two points. The unshaded values of m are entered by hand.)

_____

I'll write a couple of equations in each group so you can see how the spreadsheet numbers relate:

y = mx +b

1. y = 2x -7

3. y = 2/3x +4

8. y = 1/3x -5

9. y = -5/2x +4

What's the larger angle?

topjm [15]

Answer:

100°

Step-by-step explanation:

Since the angles om a straight line add up to 180°

10x°+8x°=180°

18x°=180°

x=10

The larger angle = 10x°

= 10(10)°

= 100°

iris [78.8K]

Answer:

both decrease

Step-by-step explanation:

mean before the 4th kitten = 153

mean after the 4th kitten = 129

hence mean decreases

median before the 4th kitten= 153

median after the 4th kitten= 150

hence median decreases
