15 - 3x = 11 - 3x + 4​

Answer:

After 3.5 hours and the charge is $82.50.

Step-by-step explanation:

Setting up the equations equal to each other will give a solution (x-value) that makes both sides equal (the same price) after the same amount of hours (x-value).

13x + 37 = 17x +23

x = 3.5

Then plug the hours into either side to get the equal price.

13(3.5) + 37 = $82.50

OR

17(3.5) + 23 = $82.50

Diameters of potatoes:

Median is:

After one potato used the median becomes 5 cm.

Out of 6 potatoes left, the two in the middle should give 5 cm in average

This is 4 cm and 6 cm.

Renee must have used one of the 4 potatoes on the left: 2 cm, 3 cm or 4 cm

Answer:

15 is the constant

Step-by-step explanation:

Does not have a variable next to it which means it remains a constant

Answer:

Your answer is: X = 11

Your equation: 7x+30=90

If you subtract 7 from 90 you get 77.

If you divide 77 and 7 you get 11.

Answer:

r = - 9

Step-by-step explanation:

Given

4r + 10 = - 26 ( subtract 10 from both sides )

4r = - 36 ( divide both sides by 4 )

r = - 9

Answer:The best prediction is 1/6 of the times or one time of the six that you will roll a two..

This is because without any interference, each of the six numbers of the dice will have same theoretical probability (which is the probability or chances that is expected.

Answer:

1

Step-by-step explanation:

[tex] a_{n} = 10 - {n}^{2} \\ \\ \: plug \: n = 5 \\ \\ a_{3} = 10 - {3}^{2} \\ \\ a_{3} = 10 - 9 \\ \\ a_{3} = 1[/tex]

Answer:

72% decrease I...guess?

120 members-60 members=50%

-70 should be approx=60%

-80  should be approx=70%

so 80 is around 70%, so I'd say 82 is 72%

I'm most likely wrong but i dunno maybe im right

Step-by-step explanation:

Answer:

32%

Step-by-step explanation:

((120 - 82) / 120) x 100 = 31.66 %

31.66% to the nearest whole percentage is 32%

Answer:

$22.5

Step-by-step explanation:

The original price is $30 and it's on sale for 25% off.  Since 25% is a quarter of the total price, I divided 30÷4=7.5.  $7.5 is 25% of $30, so 7.5 is the amount taken off the original price.  To find what Daysi paid, I subtracted 30-7.5=22.5.  $22.5 is the result after the 25% off, so Daysi paid $22.5.

Answer:

r=85

Let's solve your equation step-by-step:

−6(r−98)=78

Step 1: Simplify both sides of the equation

−6(r−98)=78

(−6)(r)+(−6)(−98)=78(Distribute)

−6r+588=78

Step 2: Subtract 588 from both sides

−6r+588−588=78−588

−6r=−510

Step 3: Divide both sides by -6

−6r/−6=−510/−6

r=85

Answer:

r=85

Answer:

85

Step-by-step explanation:

–6(r − 98) = 78

expand:

-6r+588=78

588-78=510

6r=510

510÷=85

Answer:

y=-2/3x-1

Step-by-step explanation:

You can fins the slope (or the m in y=mx+b) by counting how many units up/down and over it takes to get to another solid point and configuring it into a fraction rise/run. in this case you go down 2 units and over 3 units to get -2/3

to get the y-intercept (the b in y=mx+b) you look at where the lince intercepts the y-axis in this case it is at -1

Answer:

  x = 20, or 125

Step-by-step explanation:

We cannot tell the angle x is intended to refer to. So, here are two answers. Choose the one you think applies.

__

The triangle that includes both marked angles is a right triangle. (The tangent meets the circle at right angles to the radius.) So, the angle x° at the external point is the complement of the marked central angle.

  x° = 90° -70°

  x = 20

__

If x° is referring to the exterior angle associated with the isosceles triangle within the circle, then its measure is the supplement of the interior base angle of that triangle. It is ...

  x° = 180° -(180° -70°)/2 = 90° +70°/2

  x = 125

Answer:

Yes, I agree

The Petronas Towers are taller than the Sears tower

Step-by-step explanation:

The rule regarding spires and antenna of the Council on tall buildings and Urban Habitat states that "an antenna is just functional - something with a technical purpose stuck on the top of a building after it is finished while spires are considered a continuation of the form of the building.

According to the Council, the Petronas Towers are taller than the Sears Tower because spires are included in a building's architecture while antennae are not.

The architectural height of the Petronas towers is 1,483ft

The architectural height of the Sears (now Willis) tower is 1,450ft
