The difference of two numbers is 18. Their sum is 66. What are the numbers?​

Answer:

m = -3

Step-by-step explanation:

−m − 19 = 8m + 8  (Simplify equation)

−9m − 19 = 8  (Subtract 8m from both sides)

−9m = 27  (Add 19 to both sides)

m = -3 (Divide both sides by -9)

Step-by-step explanation:

Hey There!

To solve this problem we have to combine like terms

[tex]7x^3-6x^3=x^3\\6x^2-8x^2=-2x^2\\-5x+10x=5x\\5-7=-2[/tex]

So our answer would be

Answer:

164

Step-by-step explanation:

Answer:

Your answer is 164

Step-by-step explanation:

You add all the numbers and then divide by 5. And you will get 164.2 and you just round up to 164

So here is the work

149+183+149+193+147=821

821/5=164.2

164.2=164

Answer:

x = 134

Step-by-step explanation:

The mean of a data set is calculated as

mean = [tex]\frac{sum}{count}[/tex]

Here mean = 113, then

[tex]\frac{101+119+104+111+109+x}{6}[/tex] = 113

[tex]\frac{544+x}{6}[/tex] = 113 ( multiply both sides by 6 )

544 + x = 678 ( subtract 544 from both sides )

x = 134

The slope ("m") is 2... rise over run, the line goes up two, and then to the side once, which is 2/1 (aka 2). Since the line is going downhill, it is negative.

Answer:

0.196

Step-by-step explanation:

The probability of getting at least 2 twos will be 0.66,

Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favourable outcomes / Number of sample

Given that If a fair die is rolled 5 times, The probability of getting at least 2 twos will be calculated as,

Total outcomes = 5 x 6

Total aoutcomes = 30

Favourable oucomes = 5 x 4 = 20

Probability = 20 / 30

Probability = 0.66

Therefore, the probability of getting at least 2 twos will be 0.66.

• First let split the shape into 2 rectangles.

We’ll be using the formula: b•h (base times height)

• Small rectangle:

7x3 = 21

• Bigger rectangle:

7x11 = 77

• Now we add both, which is:

21 + 77 = 98

Answer:

V≈ 111.43 in³

Step-by-step explanation:

Equation- V = πr² × h/3

1) Divide the diameter in half to make the radius, which equals 2.85 as r.

2) Plug in the radius(r) and height(h) with the correct numbers.

3) Simply solve

V = π(2.85)² × 13.1 ÷ 3

V= 25.52 × 13.1 ÷ 3

V= 334.312 ÷ 3

V= 111.4373+

V≈ 111.43

Answer:

the simple interest here would be $220. the total amount he will receive is $2,420.

Step-by-step explanation:

to find how much interest Dan has, you use the formula,

simple interest = principal * interest rate * time

now we substitute the numbers in.

simple interest = $2,200 * 5% * 2

since the rate is a percentage, we have to convert it into a decimal.

simple interest = $2,200 * 0.05 * 2

let's do this step by step.

simple interest = $2,200 * 0.05 * 2

simple interest = $110 * 2

simple interest = $220

to find out how much Dan will earn after two years, we have to find the total amount by adding the interest and the amount of principal.

since we now know the interest, let's add it by the principal.

$220 + $2,200 = $2,420

Therefore, Dan will have $2,420 after two years.
