Since Bryan spent $15.50 less than Sarah, you would start by dividing the total amount they spent together in half.
$47.50 ÷ 2 = $23.75
Then you would take Bryan's 1/2 of the total and subtract $15.50.
$23.75 - $15.50 = $8.25
So, it looks like Bryan spent $8.25.
Check step:
If you add it all back together:
Sarah + Sarah Bryan = Total
$23.75 + $15.50 + $8.25 = $47.50
Answer:
m = 30, b = 20
Step-by-step explanation:
1. The equation is written in slope-intercept form, so it follows the following equation: y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = slope.
2. As you can see, 30 is the value that took the place of m, and 20 is the value that took the place of b.
Therefore, m is 30 and b is 20.
4^4 is simply 4x4x4x4 and 4^7 is 4x4x4x4x4x4x4
P = 2l + 2w
P = 2(119) + 2(40.40) = 238 + 80.80 = 318.80
P = 318.80
