Answer:
$7.2
Step-by-step explanation:
Given data
Weight = 1 1/4
convert to simple fraction= 5/4 pounds
The cost of 5/4 pounds of package = $9
Let us find the cost per pound
cost per pound = 9/5/4
multiply by the multiplicative inverse of the denominator
cost per pound = 9*4/5
cost per pound = 36/5
cost per pound = $7.2 per pound
Hence the cost of 1 pound of the package is $7.2
Answer:
5x(2 - 3x³)
Step-by-step explanation:
10x-15x^4
The GCF( Greatest Common Factor) of 10x-15x^4 is 5x
Solve:
10x/5x = 2
-15^4/5x = -3x³
Final answer is
5x(2 - 3x³)
<u>Check</u>
5x(2 - 3x³)
distribute
5x(2) + 5x(-3x³)
10x - 15x^4
Answer:
D
Step-by-step explanation:
A table shows a proportional relationship if all of the y/x ratios are the same.
A: 4/3 ≠ 10/6 . . . . not proportional
B: 6/12 ≠ 12/14 . . . . not proportional
C: 2/4 ≠ 20/20 . . . . not proportional
D: 1/5 = 2/10 = ... = 5/25 . . . . proportional relationship
Answer: See explanation
Step-by-step explanation:
Let the cost of the boogie board be represented by x.
The surfboard cost six times the boogie board. Therefore, surfboard =6x
The wetsuit is $300 less than the surfboard. This means wetsuit = 6x - 300
Together a boogie board, surfboard, and wetsuit cost $1,312. Therefore,
x + 6x + 6x - 300 = 1312
13x = 1312 + 300
13x = 1612
x= 1612 / 13
x = 124
Boogie board cost $124
Surfboard = 6x
= 6 × $124
= $744
Wetsuit = 6x - 300
= $744 - $300
= $444
Its dimensions are 4 and 9, or you might say this is a 4 by 9 array. We always mention the rows first and then the columns. The multiplication sentence is
4 × 9 = 36
