Answer:

5 (5x1) , -10 -(5x2), 20(10x2), -40 -(20x2), 80(40x2)

so the next number should be previous number in the sequence multiplied by 2 and a negative sign.

-`(80x2) = -160

Dwayne scored 55 points in the last basketball game, which is 10 points more than his previous personal best. Lebron scored 15 p

spin [16.1K]

Answer: a) 30, b) 120

Step-by-step explanation:

Since we have given that

Let the number of points Scored by Dwayne be 'd'.

Number of points in the last basket ball game = 55 points

According to question, we get that

$d+10=55\\\\d=55-10\\\\d=45$

Let the number of points that Chris's score be 'c'.

Number of points Lebron scored = 45

According to question, number of points scored by Chris is given by

$c+15=45\\\\c=45-15\\\\c=30$

a. How many points did Chris score during the game?

c = 30

b. If these are the only three players who scored, what was the team’s total number of points at the end of the game?

$45+45+30=90+30\\\\=120$

Hence, a) 30, b) 120

The college that Dora attends is selling tickets to the annual

Ksenya-84 [330]

Answer:

The solution of the system of equations is (11, 12)

Step-by-step explanation:

∵ The price of each student ticket is $x

∵ The price of each adult ticket is $y

∵ They sold 3 student tickets and 3 adult tickets for a total of $69

∴ 3x + 3y = 69 ⇒ (1)

∵ they sold 5 student tickets and 3 adults tickets for a total of $91

∴ 5x + 3y = 91 ⇒ (2)

Let us solve the system of equations using the elimination method

→ Subtract equation (1) from equation (2)

∵ (5x - 3x) + (3y - 3y) = (91 - 69)

∴ 2x + 0 = 22

∴ 2x = 22

→ Divide both sides by 2 to find x

∵ $\frac{2x}{2}=\frac{22}{2}$

∴ x = 11

→ Substitute the value of x in equation (1) or (2) to find y

∵ 3(11) + 3y = 69

∴ 33 + 3y = 69

→ Subtract 33 from both sides

∵ 33 - 33 + 3y = 69 - 33

∴ 3y = 36

→ Divide both sides by 3

∵ $\frac{3y}{3}=\frac{36}{3}$

∴ y = 12

∴ The solution of the system of equations is (11, 12)

Kara is sorting buttons by length for a craft project. The line plot shows the length of each button. If Kara lines up all the 3

likoan [24]

Answer:

2 and 1/4 or 2.25. Both numbers are the same.

Step-by-step explanation:

Hi,

Please see the picture I had to upload in order for this question to be complete. Please also note that Kara has 3 buttons in the 3/4 length. You have to sum up only those in that length and ignore the ones in different lengths.

It is a very simple multiplication, and there are 2 ways to do so. You can use either fractions or integer numbers. See the 2 options below:

3/4 (fractions) = .75 (integer numbers)

Option one - 3 * 3/4 = 9/4 which is represented by 2 and 1/4.

Option two - 3 * .75 = 2.25

Have a good one!
