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.
36 peanuts.
first, we would need to find what 1/4 of 48 is so we solve the equation

Now we know we need 3 times the amount that 1/4 of 48 is so we solve the next part

She will have 36 peanuts left
Answer:
Step-by-step explanation:
i belive it is correct.
Answer: A = 9
B = 11
C = 4
Step-by-step explanation:
A + B = 20
A + C = 13
B + C = 15
A + B + C = 24
Substitute 20 into our final equation for A + B.
20 + C = 24. Subtract 20 from each side.
C = 4.
Remember, B + C = 15. Substitute 4 into C to solve for B.
B + 4 = 15. Subtract 4 from both sides.
B = 11
Remember, A + B = 20. Substitute 11 for B to solve for A.
A + 11 = 20. Subtract 11 from both sides.
A = 9.
