Do you have any answer choices?
The answer is C because is n is positive and even it will only open up.
Answer:
Step-by-step explanation:
4/5 cup of brown sugar. Needs 1/4 cup. How many cups left?
Okay, so 4/5 = 0.80, 1/4=0.25.
0.80-0.25=0.55
Which is 55/100
Divide both numbers by 5
11/20
Four order pairs are ( 2, 5 ), ( 4, 8 ), ( 6, 11 ), ( 0, 2). All those I cited are whole numbers so that should help plot them, and from there get a ruler or straight edge and align all the dots to create the line for the equation. The equation you gave was the standard form which was created out of the formula to find a equation it's y = mx + b, there could be small variations made. How I know it's proportional is because all linear equations are. But if that's not enough I also know since there's a ratio or pattern that it follows and doesn't stray from. In more depth, porportional relationship is a ratio between y and x which is the same thing everytime shown if simplified.
You start with x- $3.49+$2.98= $1.79, x being the total she started with. Add the prices of the notebook ($3.49) and the pen's prize (2.98), that will equal $6.47, so our equation will be X-$6.47 =$1.79, Add 6.47 to both sides and you get X= $1.79 +$6.47 , add them together and X = $8.26. That's her original money she had.
