Answer:
Large boxes = 40 lbs.
Small boxes = 15 lbs.
Step-by-step explanation:
L = Large Box
S = Small Box
I started by making the equations, L + S = 55 and 60L + 50S = 3150. I made the first equation L = 55 - S and substituted that in for L in 60L + 50S =3150. After finding S, I plugged that back into L + S = 55 and got the answers.
Answer:
104
Step-by-step explanation:
Let's say that the numbers are x and y. So, we know that....
x+y=186
y-x=22
Now we can use the substitution method to find the numbers. y-x=22 turns into y=22+x. And now we can substitute to the second equation into the first equation.
x+22+x=186
2x=164
x=82
y=22+82
y=104
Our numbers are 82 and 104 and the larger integer is 104, so that's the answer.
Answer:
4 packages
Step-by-step explanation:
1 yard= 3 feet
5.6 yards= 16.8 feet
16.8 feet / 4 feet = 4.2
So 4 packages
Answer:
y = 2x + 7
Step-by-step explanation:
Slope Formula: 
Slope-Intercept Form: y = mx + b
We are only focusing on the line of best fit.
Step 1: Find 2 coordinates
(0, 7) y-intercept
(2, 11) random
Step 2: Find slope <em>m</em>
m = (11 - 7)/(2 - 0)
m = 4/2
m = 2
y = 2x + b
Step 3: Rewrite linear equation
y = 2x + 7
