Answer:
x = -6
Step-by-step explanation:
expand the brackets:
7x+28 + 6x-18 = 8x-24 - 2x-8
now, collect like terms:
13x + 10 = 6x -32 (subtract 6x from both sides)
7x + 10 = -32 (minus 10 from both sides)
7x = -42 (divide by 7)
x = -6
sub into the original formula to check
Answer:
Length= 8, Width= 4
Step-by-step explanation:
Say the length is l, and the width is w.
We can set l, the length as 2w, as it is double the length.
The perimeter= 2l + 2w= 24
Input l as 2w, get
4w+2w=24
6w=24, w=4.
Length is w*2, so length is 8.
John Doe makes 420,000 from basketball, and 3,200,000 which is 3,620,000 combined which is 300,039,000 less than Bobby Smyth (3.00039 x 10^8) i believe
Let x = the unknown number to get x = 6
<span>200 < 225 + 80x < 550
The 200 is the amount the Jenna currently have.
225 + 80x is the amount that Jenna has to pay given x number of hours.
550 is the sum of Jenna's 200 and additional 350 she can get by selling pre-ordered Cds. This is the maximum amount she can pay for the studio rental and sound technicians.
225 + 80x < 550
80x < 550 -225
80x < 325
80x / 80 < 325/80
x < 4.06 or 4 hours
225 + 80x </span>→ 225 + 80(4) = 225 + 320 = 545
<span>
The number of hours for the sound technician will range from 1 hour to 4 hours.
Assuming they will use 6 hours.
225 + 80(6) = 225 + 480 = 705
705 - 550 = 155
Jenna has to raise an additional $155 to pay off the studio rent and 6 hours of sound technicians.
