Answer:
267mph or 268mph
Step-by-step explanation:
Well the exact answer is about 267.8 so depending on if you round up or down there are two answers.
1km = 0.62137119mi
So 431 • 0.62137119 = 267.8
Answer:
Jan bought 4 steaks and 6 watermelons.
Step-by-step explanation:
let the number of steaks sold be x
let the number of watermelons sold be y
the following information were given:
x + y = 10 - - - - (1) ( bought a total of 10 steaks and watermelons.)
5(x) + 4.5(y) = 47 - - - - - (2) (Jan spent $47)
let us solve for x and y as follows:
x + y = 10 - - - - (1)
x = 10 - y - - - - (3)
putting the value of x in equation (3) to replace x in equation (2)
5(x) + 4.5(y) = 47 - - - - - (2)
5(10 - y) + 4.5(y) = 47
50 - 5y + 4.5y = 47
50 - 0.5y = 47
50 - 47 = 0.5y
3 = 0.5y
∴ y = 3 ÷ 0.5 = 6
since we know the value of y, the value of x is solved using equation 3 as follows:
x = 10 - y - - - - - (3)
x = 10 - 6 = 4
Therefore, Jan bought 4 steaks and 6 watermelons.
Answer:
28 ft x 20 ft
Step-by-step explanation:
Perimeter = 2xlength+2xwidth
let's say width = w and length = 2w-12
Plug that back in: 96 = 2(2w-12)+2(w)
Solve algebraically: 96 = 4w-24+2w
96=6w-24
6w=120
w=20
Plug that back into length: 2(20)-12 = 40-12 = 28
Therefore, 28 ft for length and 20 ft for width, or 28 ft x 20 ft
