Answer:

80

Step-by-step explanation:

hope it helps . .. ..,......

Answer:

80

Step-by-step explanation:

7 tens = 70

3 more ones than tens = 3 + 7 = 10

10 ones = 10

70 + 10 = 80

Answer:

Variable means the letters represent the unknown number. So you can use any letter to represent Han's age......the most common letter "x, y, t, f, a, b" but you can use any letter

Step-by-step explanation:

Answer:

Take the square root of a number that is not a perfect square. None of the numbers are perfect squares. After you do that you can do any closed operation you want with the resulting irrational and the two other rationals and you will end up with an irrational.

8*24*√5 is an example.

8+24+√5 is another

5*√8 + 24 is another.

If you take the cube root of any number that isn't a perfect cube you get an irrational, so you could take the cube root of 5 or 24 instead of the square root and do the same thing.

Answer:

q=pr/s

Step-by-step explanation:

p/q=r/s multiplication is the inverse of division so they cancel out. and you have to do the same thing to both sides so multiply both sides by "q" it cancels out on the left and stays on the right leaving you with

q=pr/s

35÷33=564i3937202p33883

Answer:

1 in 26

Step-by-step explanation:

there's only one first letter in your first name, and twenty-six letters in the alphabet.

Given the points (0, -1) and (6, 1), we need the following information to solve for the equation of the line:

We need the slope and the y-intercept.

Let (x1, y1) = (0, -1)

(x2, y2) = (6, 1)

Substitute these values into the following slope formula:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - (-1)}{6 - 0} = \frac{1 + 1}{6} = \frac{2}{6} = \frac{1}{3}[/tex]

Therefore, the slope (m) = 1/3.

Next, we need the y-intercept, (b), which is the point on the graph where it crosses the y-axis. It is also the value of the y-coordinate when its corresponding x-coordinate = 0.

Looking at one of the given points, (0, -1), this represents the y-intercept. Therefore, the y-intercept (b) = -1.

Now that we have our slope, m = 1/3, and y-intercept, b = -1, we can write our linear equation in slope-intercept form as:

y = 1/3x - 1

Answer: 2.3 / -3

Step-by-step explanation: If you want me to to explain it, just ask!

Answer:

y = -2.5/3x

Step-by-step explanation:

[tex]m = \frac{y2-y1}{x2-x1}[/tex]

[tex]m = \frac{7.5-5}{3-6}[/tex]

[tex]m = \frac{2.5}{-3}[/tex] or -0.83333

y = -2.5/3x

Answer:

$68.74

Step-by-step explanation:

Original: $99.99

New: x

Tax: $8.75

Discount : 40%

Discounts are applied before tax.

40% of 99.99 = 0.40(99.99) = 39.996

99.99 - 39.996 = 59.994

Apply tax:

59.994 + 8.75 = 68.744 ≈ 68.74

-Chetan K

Answer: 68.74

Step-by-step explanation:

99.99 * .60 = 59.994

59.994 + 8.75= 68.744

Answer:

B 105

Step-by-step explanation:7x = 5x + 30 alternating interior angles

2x = 30

x =15

7x = y corresponding angles

7(15) = y

y= 105

Answer: (x+2)*(x-4)*(x+21) = 0 has "many" solutions

Step-by-step explanation: (x+2) = 0 only has one solution.  

(x+2)*(x-4) = 0 has two solutions, -2 and 4

(x+2)*(x-4)*(x+21) = 0 has three solutions, -2, 4, and -21, etc

If "many" means more than three, then add another (x+XX) term.  A quadratic equation generally has two solutions.

Brainliest please?

l=V/w[h]

Hope this helps

The variable "h" belongs in the green box

Answer:

Assume there are 5x red beads and 9x green beads

Total no. of beads = 5x+9x = 14x

Fraction of beads that are red = 5x out of 14x

or 5/14
