Hi!

I can help you with joy!

Recall that the sign ">" means "greater than"

So, we need to find a number that would make the inequality false.

Is it 9? Nope, 9 is greater than 8, so 9 would make the inequality true.

So, we need to find a number less than 8.

Is it 7? Yes, 7 is less than 8, so 7 would make the inequality false.

7>8 (False)

Hope it helps!

Enjoy your day!

Answer:

Anything under 8.

Step-by-step explanation:

Anything under 8, (7, 6, 5, 4, etc.) would make the inequality false. "Inequality" means difference in size, degree, circumstances, etc.; lack of equality. ">" means greater than, so, to make the equation false, insert something less than 8.

Answer:

x = 8[tex]\sqrt{3}[/tex] in

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + 22² = 26²

x² + 484 = 676 ( subtract 484 from both sides )

x² = 192 ( take square root of both sides )

x = [tex]\sqrt{192}[/tex] = [tex]\sqrt{64(3)}[/tex] = [tex]\sqrt{64}[/tex] × [tex]\sqrt{3}[/tex] = 8[tex]\sqrt{3}[/tex] in

Answer:

6a:10b

Step-by-step explanation:

Make both C's equal eachother which we could make 12

4x3=12 and 6x2=12

so we will have to do the same for the other numbers so when 4x3=12 then 2x3=6 and then do the same for 5b where 6x2=12 and 5x2=10

this would make the ratio 6a:12c:10b which would then make the ratio 6a:10b

Answer:

295

Step-by-step explanation:

138+157=295

Answer:

There are 300 paperclips now in the jar.

Step-by-step explanation:

138 + 157 = 295. If you have to estimate, 5 rounds up so you estimate it up to 200.

There are 300 paperclips now in the jar.

If it does not want you to round, answer 295.

Answer: So the answer wont be C or D because it doesn't get over 43.2 inches of water so if you do 43.2 -- 1.8 it will equal 41.4 inches

MARK ME BRAINLIEST!!!!!!!!!!!!!!!

The city's mean annual rainfall is 40.5 inches, option A is correct.

It is a branch of mathematics that deals with the occurrence of a random event.

We know that P(z ≥ 1.5) = 0.0668

From the standard normal distribution table, we can find that the z-score corresponding to a right-tailed probability of 0.0668 is approximately 1.5. Therefore, we have:

z = 1.5

We can use the formula for the z-score:

z = (x - μ) / σ

where x is the observed value, μ is the mean, and σ is the standard deviation.

Substituting the given values, we get:

1.5 = (43.2 - μ) / 1.8

Solving for μ, we get:

μ = 43.2 - 1.8 × 1.5 = 40.5

Therefore, the city's mean annual rainfall is 40.5 inches.

Answer:

The answer is n = -14 .

Step-by-step explanation:

4 = 1/2(n + 22)

4 = 1/2n + 11

-7 = 1/2n

-7 / 1/2 = -14 = n

To check your work:

4 = 1/2(-14 + 22)

4 = 1/2(8)

Answer: 1 1/3 servings of pasta on the shelf.

Step-by-step explanation:

All you need to do is 8*1/6 because if there are 1/6 of a serving of pasta in each box and you have 8 boxes, then you need to multiply to find the number of servings.

8*1/6=1 1/3 or 1.(3)

(3) or any other number in parentheses next to a decimal means it's a repeating decimal, and it never ends.

Answer:

25

Step-by-step explanation:

First we need to create an equation. We’ll say the losing team scored x points. If the winning team scored 19 more, they would have x + 19 points. We know the total is 31 points, so we end up with x + x + 19 = 31, or 2x + 19 = 31. Subtract 19 from both sides to get 2x = 12. Divide both sides by 2, and get x = 6. To find out how much the winning team scored, which we know is x + 19, put 6 in for x and get 25.

Answer:

B

Step-by-step explanation:

4x - 3y = 9 → (1)

4x + y = 7 → (2)

Rearranging (1) in terms of x or y will involve using fractions, which we want to avoid if possible.

However, using equation (2) avoids introducing fractions.

In (2) subtract 4x from both sides

y = 7 - 4x → (3)

Then substitute y = 7 - 4x into (1) and proceed

Equivalent expressions are expressions that have equal values

The value of x is 25/6

From the question, the values of ac and ec are equivalent

So, we have:

8x - 14 = 2x + 11

Collect like terms

8x - 2x = 14 + 11

Evaluate the like terms

6x = 25

Divide both sides by 6

x = 25/6

Hence, the value of x is 25/6

Answer:

300 cents or $3

Step-by-step explanation:

Let p be the cost of one pen and m be the cost of one mechanical pencil. We can use this to set up a system of equations:

4p+6m=1620 (convert $16.20 to cents by multiplying it by 100)

m=70

We can solve this using substitution (substitute 70 for m):

4p+6(70)=1620

4p+420=1620

Subtract 420 from both sides

4p=1200

Divide both sides by 4

p=300 cents or $3
