Answer:
453.6 grams
Step-by-step explanation:
40 x 5.67 = 226.8
226.8 x 2 = 453.6
Subtract what has already been loaded from total amount allowed:
23500 - 9700 = 13,800
Divide the amount left by the weight of each crate:
13,800 / 70 = 197.14
They can load 197 crates.
Answer:
x=1.94
x = - 1.94
Step-by-step explanation:
8x² + 5 = 35
Subtract 5 from each side
8x² + 5-5 = 35-5
8x² = 30
Divide each side by 8
8x² /8 = 30/8
x² = 15/4
Take the square root of each side
sqrt( x²) = ±sqrt(15/4)
x = ±sqrt(15/4)
x=1.93649
x = - 1.93649
To the nearest hundredth
x=1.94
x = - 1.94
Answer:
{y,x} = {0,1}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 3x - 3
// Plug this in for variable y in equation [2]
[2] -3•(3x-3) - 9x = -9
[2] - 18x = -18
// Solve equation [2] for the variable x
[2] 18x = 18
[2] x = 1
// By now we know this much :
y = 3x-3
x = 1
// Use the x value to solve for y
y = 3(1)-3 = 0
