Answer:

A) p = 2x - 4 for the expression. B) Your team scored 44 points.

Step-by-step explanation:

Let <u>P</u> represent the points your team made.

Since the question says "Your basketball team scored 4 fewer than twice as many points as the other team." this is how I came up with the expression.

p = 2x - 4 ( our points = 2 times more then the other teams points minus 4.

Using this expression and the given information that the other team made 24 points, I solved B.

44 = 2(24) - 4.

Charlene is a video game designer and wants to make sure that her games can be played on all types of screens. In order for the

Nikitich [7]

Answer:

The playable area has a width of 9 inches and a height of 6 inches.

Step-by-step explanation:

There are a number of ways you can get there.

1. Check the answers to see which have the right area and aspect ratio.

A: area = 24 in² — does not match 54 in²

B: area = 54 in², aspect ratio 6:9 = 2:3 — does not match 3:2 aspect ratio

C: area = 54 in², aspect ratio 9:6 = 3:2 — matches problem statement

D: area = 121.5 in² — does not match 54 in²

2. If the screen were 3:2 (inches), its area would be 6 in². The area of 54 in² is 9 times that value, so the actual screen dimensions are √9 = 3 times 3:2. That is, they are width:height = 9:6 inches — matches selection C.

3. You can write equations for width and height and solve.

w/h = 3/2

wh = 54

Substituting w=3/2·h into the second equation gives

... (3/2)h·h = 54

... h² = 36 . . . . . multiply by 2/3

... h = √36 = 6 . . . . square root, result in inches

The account balance of each of three children at the end of a month is shown below:

xeze [42]

Answer:

A) See attached.

B) Cheryl owes the bank more.

Step-by-step explanation:

Given account balances:

John: -$2.75
Cheryl: -$3.00
Andrew: $2.75

(Andrew has as much savings in his account as the amount John owes).

Draw a straight, horizontal line with arrows on both ends.
Place a tick in the center of the line and label it zero.
Draw 4 evenly spaced ticks either side of the zero.
Number the ticks to the right of the zero 1, 2, 3 and 4.
Number the ticks to the left of the zero -1, -2, -3, and -4.
Mark -2.75, -3 and 2.75 on the number line.
Label the marks with John, Cheryl and Andrew.

(See attached number line).

The <u>absolute value</u> of a number is its <u>positive numerical value</u>.

To calculate how much John and Cheryl owe the bank, take the absolute values of their account balances:

John: |-2.75| = 2.75

Cheryl: |-3.00| = 3.00

As 3.00 > 2.75, Cheryl owes the bank more.
