20 laps at 400 yds per lap = (20 x 400) = 8000 yds
1680/8000 = 0.21....multiply by 100 to get ur percent (100 x 0.21) = 21%
Answer:
m is the slope and b is the y-intercept. Therefore, for the equation y=x+5 , the slope is 1 , and the y-intercept is 5
Step-by-step explanation:
Answer:
To begin this problem we call "the sum of the number" x. Now we have the equation 2(x)+5=20. This is the answer because it said to translate the equation. I think 2x+5+20 would be the correct translation.
2a+1b=27.50
4a+2b=59.50
Multiply first equation by -4 and the second by 2 so you can drop off the a values then add the equations together. Then solve for b. You should get b=6.
Then plug b into one of the original equations and solve for a and you should get 10.75
So a plate of spaghetti is $10.75 and a salad is $6.
Answer:
307.6
Step-by-step explanation:
190+224.50= 384.5 - 20% = 307.6
