Answer:

x = 8

Step-by-step explanation:

1.-4x + 14 = -18

-4x + 14–14 = -18–14

2.-4x = -32

3.-4x = -32

-4x -32

-4 -4

4.x = 8

Answer:

x=8.

Step-by-step explanation:

Collecting like terms,

-4x=-18-14

-4x=-32.

Dividing both sides by -4,

x=8.

Answer:

7.18

Step-by-step explanation:

remember you can rearrange the equation by doing the SAME THING on BOTH SIDES.

q + 2.02 -2.02=9.2-2.02

simplify and you get:

q=7.18

Answer:

7.18 {final answer}

Step-by-step explanation:

→ q + 2.02 = 9.2

→ q = 9.2 - 2.02

→ [ q = 7.18 ]

Answer:

Total amount wanted = 800

Step-by-step explanation:

480 represents 60% of the total amount

Let the total amount = x

60/100 * x = 480                           Multiply both sides by 100

60*x = 480 * 100                           Combine

60*x = 48000                                Divide by 60

x = 48000 / 60

x = 800

Answer:

It would be 1

Step-by-step explanation:

The equation is ( 6-2) divided by ( 3 +1)
Using GEMDAS we do the groups first so
6 - 2 = 4
3 + 1 = 4
Divide 4 by 4 and the answer is 1

Answer:

obtuse

Step-by-step explanation:

if one angle is 25 and the other 50, then the third angle is 105, because all three angles have to add up to 180. So it is a obtuse triangle.

Answer and explain:

1st person: 70 % throws

70/100x80 = 56 out of 80 throws

2nd person: 60% throws

60/100x80 = 48 out of 80 throws

3rd person 50% throws

50/100x80 = 40 out of 80 throws

56+48+40/80x3 = 77/120​

One equation that gives the estimated number of free throws (all the 3 people) is 77 out of 120. The best player will make about 56 out of 80 free throws.

Answer: Below

Step-by-step explanation:

A trick to always find the volume of a three dimensional object is that you multiple base by height. So, we want to fid the area  of the circular base first. Using the formula 2 · pi · r²:

2 · 3.14 · 8² = 401.92

We use 3.14 for pie since they asked us to. Now we multiply base by height.

401.92 · 6 = 14469.12

Our answer is 14469.12

Answer:

V=150.72

Step-by-step explanation:

The formula for the volume of a cylinder is V= \pi x r^2 x h

So you would do 3.14x4^2x3

4^2 is 16 so then you have 3.14x16x3, multiply them all together and get 150.72! Hope this helped :)

Answer:

18.125 pounds

Step-by-step explanation:

7.5 x 2.5

Answer:

It's C 18.125 because it said the baby's weight is 2 1/2 times. So you would multiply 7.25 by 2 1/2 and get 18.125.

Answer:

The answer is 260 campers.

Step-by-step explanation:

If 15% liked swimming(39 people), you need to see how many times 15% can go into 100% with whole numbers. It is 6 times. (15x6=90). Do 39 campers times 6 = 234. Now there is 10% remaining. Well 10 is two thirds of 15(5+5=10add another 5 to get 15). So now you need to find what two thirds of 39 is. Simple! Do 39/3=13. 13+13=26(13 is ONE THIRD of 39. Multiply it by 2 and it would be TWO THIRDS).

Okay, we have 234 + 26 = 260!!!

This makes no sense at all what should I help with?im sorry there is no question there to answer

Answer: 15,17,19,21,23

Step-by-step explanation:

You can let the middle number = x, then the numbers are

x-4, x-2, x, x+2, x+4

Plugging it back in to what is given,

x-4+x-2+x = 7+x+2+x+4

3x-6 = 2x + 13

x = 19

The numbers are 15, 17, 19, 21, 23

a. The probability is 1/100 since there are 10 possible digits (0-9) and you need the last two digits so [tex]\frac{1}{10}*\frac{1}{10}=\frac{1}{100}[/tex].

This is 1%.

b. Let's start by calculating the probability of getting the right digits knowing that they are both even.

We have a total of 5 even digits (0, 2, 4, 6, 8). You need the last two so [tex]\frac{1}{5}*\frac{1}{5} =\frac{1}{25}=\frac{4}{100}[/tex] which is 4%.

Therefore the answer is a) It increases the probability that your choice is correct to 1/25, or 4%, because each digit could be 0, 2, 4, 6 or 8.

Area of quater of circle is [tex]\frac{\pi r^2}{4}[/tex]

Radius = 3

(A = Area)

A = [tex]\frac{3^2\pi }{4}[/tex]

A = [tex]\frac{9\pi }{4}[/tex]       (The order of steps doesn't matter whether you divide 9 by 4 first or times 9 with [tex]\pi[/tex]. I'm going to divide 9 with 4 first)

A = 2.25[tex]\pi[/tex]

Area (With [tex]\pi[/tex] --> 3.14 aprx.) = 7.065

Answer:

Step-by-step explanation:

1. (you subtract 17 because of the fine) 62-17=45

2. (you divide 62 by 9 because its the price per hour)62/9=5

Answer:

Step-by-step explanation:

2. 3/4 x 7/5 > 3/4

3. 3/4 x 5/5 = 3/4

4. 3/4 x 2/5 < 3/4

5. Multiplying a number by a fraction greater than 1 (ex: 2*1.5 = 3) results in a product greater the the number we started with. Multiplying a number by a fraction less than 1 (ex: 2*0.7 = 1.4) results in a produce smaller than the number we started with. Multiplying a number by a fraction equal to 1 (ex: 2*1 = 2) results in a product equal to the number we started with.  

Hope this helps!

Answer:

18

Step-by-step explanation:

A square has 4 sides of equal length.

The perimeter of the square is the sum of the lengths of the sides of the square.

P = perimeter; a = length of 1 side

P = a + a + a + a

P = 4a

We are told the perimeter is 72 yd.

4a = 72 yd

Divide both sides by 4.

a = 72/4 yd

a = 18 yd
