Solve 4x - 9 = 15

2 answers:

7 0

It’s b because negative 9 turns into positive 9 to cancel out the number to isolate variable. Then you also add positive 9 to 15 and that makes 24. But don’t forget about 4x which divide into 4x/4 and 24/4 to again isolate the variable. Then 24/4 = 6

4x - 9 = 15

Add 9 on both sides (-9 + 9 cancels out and 15 + 9 = 24)

4x = 24

Divide by 4 on both sides (4 / 4 cancels out and 24 / 4 = 6)

x = 6

The answer is B

A high school track is shaped as a rectangle with a half circle on either side.

Ilia_Sergeevich [38]

Answer:

Option (3)

Step-by-step explanation:

Track is shaped as a rectangle with a semicircle on either side.

Therefore, length of the track = 2(Length of rectangle) + perimeter of a complete circle formed by joining the semicircles on each side.

= 2(96) + 2πr

= $192+2\pi (\frac{35}{2})$

= 192 + 35π

= 192 + 109.9

= 301.9 m

Since, Jake plans to run four laps.

Therefore, distance covered by Jake = 4 × 301.9

= 1207.6 m

Option (3) will be the correct option.

Consider an experiment with a deck of 52 playing cards, in which there are 13 cards in each suit, two suits are black, and two s

lakkis [162]

Answer:

P (E1) = 1/2 or 50%

P (E2) = 3/13 or 23%

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of playing cards = 52

Number of suits = 4

Number of cards per suit = 13

Number of black suits = 2

Number of red suits = 2

2. Suppose E1 = the outcome is a red card and E2 = the outcome is a face card (K, Q, J). Determine P(E1 or E2).

P (E1) = Number of red cards/Total of playing cards

P (E1) = 26/52 = 1/2 = 50%

P (E2) = Number of face cards/Total of playing cards

P (E2) = 12/52 = 3/13 = 23%

Circle the expression(s) that give the same product as 6 x 3/8.

34kurt

Answer:

(6 × 3) divided by 8 and 3/8 × 6

Step-by-step explanation:

if you solve 6 × 3/8 you should get 18/8 which then simplifies to 9/4. if you go though each answer choice solving each problem you should get 9/4 and if you dont then that is not the answer. the first 2 answer choices equal 16 which is not 9/4 and the 4th answer choice will give you 4 and 6 × 8/3 gives you 48/3 which gives you 16 so only the 3rd and last answer choices are correct
