Answer:
A) (15 x $3) + (10 x $2) + (12 x $1) = X
B) $77
Step-by-step explanation:
A) Each wrapping paper is 3 dollors, and they bought 15 (15 x 3)
Each greeting card is 2 dollors, and they bought 10 (10 x 2)
Each roll of ribbon is 1 dollors, and they bought 12 (12 x 1)
B) 15 times 3 is 45
10 times 2 is 20
12 x 1 is 12
45 + 20 + 12 = 77
The new volume will be 480 inches cubed
(86 + 70 + 79 + 90 + 85 + x)/6 = 84
Multiply 6 to both sides and then add everything together and then subtract i from the multiplied 86 which will get you 94.
Answer: 94
Factor the quadratic equation (3x-4)(x+3). Then set the factors equal to zero.
3x-4=0, solve to get 4/3
x+3=0 x=-3
Answer:
<u>1/8910720</u>
Step-by-step explanation:
Number of ways they can be chosen :
⇒ 17 × 16 × 15 × 14 × 13 × 12
⇒ 272 × 15 × 14 × 13 × 12
⇒ 4080 × 14 × 13 × 12
⇒ 57120 × 13 × 12
⇒ 742560 × 12
⇒ <u>8910720</u>
Hence, the probability will be :
⇒ P = 1 / number of ways
⇒ P = <u>1/8910720</u>
