Answer:

17

Step-by-step explanation:

let the two numbers be X and Y

let larger number = Y

from the first statement

Y - X = 9 equation (1)

from the second statement

Y = 1+ 2X equation (2)

substitute equation (2) into (1)

1+2X-X = 9

1+X= 9

X = 9-1 = 8

X= 8

put X = 8 into equation (2)

Y= 1+2X

Y= 1+2(8)

Y= 1+16 = 17

larger number = 17.

The inequality that represents the scenario is x > 8

From the question, we understand that:

Abel ran more than 8 miles this week

Let the number of miles be x.

The text "more than" means that we make use of the greater than inequality symbol

So, the inequality that determines the steps is:

Answer:

9

Step-by-step explanation:

Given equation:

[tex]5 = \dfrac{x}{3} + 2[/tex]

To determine the solution (x) of the equation, we need to isolate it.  To do this, we can subtract 2 both sides of the equation.

[tex]\implies 5 - 2 = \dfrac{x}{3} + 2 - 2[/tex]

[tex]\implies 3 = \dfrac{x}{3}[/tex]

To further isolate "x", we can use cross multiplication.

[tex]\implies 3 \times 3 = x[/tex]

Finally, simplify the expression on the left-hand-side to obtain the value of x.

[tex]\implies \boxed{9 = x}[/tex]

A fraction is equavalent to the top number divided by the bottom number.

5/8 is equivalent to 5 ÷ 8

Answer: C.  5 ÷ 8

For the given arithmetic sequence we have:

We know that we have 20 seats on the front row, and then we add 3 more on each row, so the formula will be:

[tex]A_n = 20 + (n - 1)*3[/tex]

This gives the number of seats on the n-th row.

B) The last row has 83 seats, then we need to solve:

[tex]A_n = 20 + (n - 1)*3 = 83\\\\(n - 1)*3 = 83 - 20 = 63\\\\n - 1 = 63/3 = 21\\\\n = 21 + 1 = 22[/tex]

So we conclude that there are 22 rows.

C) The total number of seats will be:

[tex]\sum_{n = 1\ to\ 22} (20 + (n - 1)*3)[/tex]

D) Instead of using the sum above (we should add 22 terms) we use the general formula for the sum of N terms in an arithmetic sequence:

[tex]S_N = (N/2)*(2A_1 + (N - 1)*d)[/tex]

In this case, we replace N by 22, and d is the common difference of the sequence, which we know is equal to 3, so we wil have:

[tex]S_{22} = (22/2)*(2*20+ (22 - 1)*3) = 11*(40 + 21*3) = 1,133[/tex]

There are 1,133 seats in total.

I did this before. I'm 14 :D

E-

y=20x

Eli ironed 2 more hours and got 400 shirts.

S-

y=35x

Let x be the number of shirts ironed.

400/20x = 20.

20-2=18.

That means she ironed 360 shirts prior.

If both of them were at the same speed of 18 by (let x represent). Then Samantha ironed 630 shirts while Eli ironed 360 shirts, but ironed 2 more hours which got him to get 400 shirts.

Step-by-step explanation:

Mean = (61+59+60+50+54+56+61+63)/8

= 464/8

= 58 degrees

Deviations:

61 - 58 = 3

59-58 = 1

60-58 = 2

50-58 = -8 = 8   (absolute value)

54-58= -4 = 4

56-58 = -2 = 2

61-58 = 3

63-58 = 6

MAD = (3+1+2+8+4+2+3+6) / 8

= 3.6 to the nearest tenth.

Explanation:

The tickmarks tell us that sides HG and FG are the same length. The triangle is isosceles. Directly from this, we know that the opposite angles F and H are congruent. Both are 4y-7 degrees.

Angle G is 90 degrees because of Thales' Theorem. This is because HF is the diameter of the circle. It's also the hypotenuse of the right triangle.

For any triangle, the three interior angles always add to 180 degrees.

F+G+H = 180

(4y-7) + (90) + (4y-7) = 180

8y + 76 = 180

8y = 180-76

8y = 104

y = 104/8

y = 13

Answer:

what does a this mean? .54 is a decimal

Answer:

Step-by-step explanation:

When you square a number, whether it's positive or negative, the square is always positive.  That is, a2 is positive whether a is positive or negative.  Examples:

12 = 1 x 1 = 1

(-1)2 = (-1) x (-1) = 1

52 = 5 x 5 = 25

(-5)2 = (-5) x (-5) = 25

Since the answer is always positive, you don't need the absolute value signs: |a2| = a2.

Hail is a form of precipitation when droplets of water freeze together in the cold upper reaches of the thunderstorms.  

Thee chunks of that range from 5 to 15 cm can be round and jagged. Hail fall on the ground in a solid form they are often associated with tornadoes and certain parts of the world receive more hail than other parts do.

These frozen droplets of water when fall from the clouds get uplifted by wind and that adds another layer to them. The freezing occurs below the zero degrees at an altitude of 11,000 feet.

Rationalising the denominator of the given fraction means we need to multiply both the numerator and the denominator of the fraction by the conjugate of the expression in the denominator. For example:

[tex]\;\longrightarrow\dfrac{1}{a+b}[/tex]

Here the conjugate of denominator of the expression is a - b. So we need to multiply both the numerator and denominator with the fraction.

[tex]\;\longrightarrow \dfrac{1}{a+b} \times \dfrac{a-b}{a-b}[/tex]

Hence, this is what the rationalization means.

We have been given and equation and we have been asked to rationalise the equation.

The conjugate of the denominator of the given equation is √(x² + y²) - x. Therefore;

[tex]\implies \dfrac{y^2}{\sqrt{x^2+y^2}+x} \times \dfrac{\sqrt{x^2+y^2}-x}{\sqrt{x^2+y^2}-x}[/tex]

Answer:

x = 1.5 or 3/2

Step-by-step explanation:

First, expand the equation.

(2x - 3)² = 0

(2x - 3)(2x - 3) = 0

In similar equations, we would solve for both pairs of parenthesis. However, since the equations inside both are the same, we only need to solve for ONE of them, bringing one correct answer.

2x - 3 = 0

Add 3 to both sides.

2x = 3

Divide both sides by 2.

x = 3/2 or 1.5.
