i think its 158

Step-by-step explanation:

i think what theyre doing here is a pattern because

79-55=24 and 110-79=31 which has no pattern but when u subtract 55 from 110 you get  110-55=55  so i just multiplied 79 by 2 getting the answer 158.

I NEED HELP PLEASE!!!

Answers

Answer:

13 seconds

Step-by-step explanation:

Since distance is directly proportional to time,

distance = time * a constant

Lets make A the constant

So, 54 = 9A

A = 6

Now, since distance = 78,

78 = time * A

From above, we can see that A = 6, so

78 = time *6

time = 13

Answer:

13

Step-by-step explanation:

54/9=6, 6 is the rate at which the car travels. 78/6 is 13 so that is how far the car traveled

What is the next number in the pattern below?

3, 9, 27, 81

Answers

Answer:

243

Step-by-step explanation:

the reason why it's 243 is because 3 x 3 = 9, 9 x 3 = 27, and 81 x 3 = 243.

Answer: Step-by-step explanation: 243

Lets look at the difference between the first two numbers (3 and 9). to get from 3 to 9, we either have to multiply by 3, or add 6.

Next, let's look at the difference between 9 and 27. to get from 9 to 27, you have to multilpy by 3, or add 18.

If we conitnue to multiply the previous by 3, we get the following number, therefore we know the answer is to multiply by 3.

if we multiply 81 by 3, we get 243

Kiera and Trina joined a gym. The gym offers two different payment plans. Kiera chose Plan 1 and pays $25 a month and no fee to join. Trina chose Plan 2 and pays $10 a month, plus a $100 joining fee. Which equation models Kiera’s total payments, t1, and Trina’s total payments, t2, after m months?

Answers

Answer:

t1 = $25m

t2 = $(10m + 100)

Step-by-step explanation:

Here we want to write equations

Kiera chose plan 1

$25 monthly and no joining fee

So the amount after m months will be 25 * m

t1 = $25m

Trina chose plan 2

$10 a month and $100 joining fee

after m months , total payment will be

10(m) + 100 = $(10m + 100)

Thus t1 = $25m and t2 = $(10m + 100)

Answers

Answer:

x=7

Step-by-step explanation:

set up the equation equal to each other

8x=2x+42

subtract 2x from 8x.

equation should look like: 6x=42

divide 6x by 42

equal x=7

Answer:

x = 7

y = 56

Step-by-step explanation:

Sub y = 8x into first equation

8x = 2x + 42

Rearrange by collecting like terms

8x - 2x = 42

6x = 42

x = 7

Sub x = 7 into second equation

The perimeter of a rectangle is 36 m. If the length is three times the width, what is the length?

Answers

Answer:

13.5 meters

Step-by-step explanation:

As the rectangle has 4 sides and the length is three times the width, each pair of a long side and a short side has a perimeter of 18 meters. As the ratio is 3:1, there are 4 parts in 18 meters, and 18 divided by 4=4.5. As the length covers 3 parts, and there are 4.5 meters per part, 4.5x3=13.5. The length of the rectangle is 13.5 meters. Hope it helps!

Given that 2x + 1 =5, what is the value of (x+3)^3

Answers

Answer: 125

Step-by-step explanation:

First, solve for x in the first equation.

1) Subtract 1 from both sides.

2x = 4

2) Divide by 2 on both sides.

x = 2

Next, substitute the value of x into the second expression.

(2 + 3)^3

= 5^3

= 125

Answer:

The value of (x + 3)³ is 125.

Step-by-step explanation:

First, we have to find the value of x.

To do so, start with the first equation, 2x + 1 = 5.

We can easily solve this equation to find the value of x.

First, start by subtracting 1 from each side.

This leaves us with 2x = 4.

Next, divide by two on each side.

This will leave us with the answer x = 2.

Now we know the value of x = 2.

All that's left to do is substitute the value of x, 2, for x.

First, start with the second equation (x + 3)³.

We know that x is equal to 2, so we can enter 2 for x.

We then have the equation (2 + 3)³.

Next, solve.

Add the 2 and the 3 together.

Now, the equation is 5³.

5³ is equal to 5 · 5 · 5

5 · 5 · 5 = 125

To sum up,

We found out that x = 2

Using 2 for x, we found out that (x + 3)³ is equal to 125.

How many solutions does the equation have? 4(3-5)+2=4-18 please help ​
