Answer: I think that the answer is either 11 avocados or 9

Step-by-step explanation:

21-2.50 is 18.50

with this he can buy 9 with 15 dollars but he still has 3.50 left over

if he uses this left over change he can buy two more which would make 11.

If this is wrong I am sorry!

Answer:

2.50 + 5B ≤ 21;

Step-by-step explanation:

Cost of eggs = $2.50

Cost of avocado = $5 (bag of 3)

Total budgeted amount = $21

Bags of avocado = B

Therefore :

(Cost of eggs + cost of avocado) ≤ total budgeted amount

($2.50 + $5(B)) ≤ 21

2.50 + 5B ≤ 21

5B ≤ 21 - 2.50

5B ≤ 18.50

B ≤ 18.50 / 5

B ≤ 3.7

Therefore the maximum number of bags can purchase is 3(whole number without exceeding $21)

3/7 times 7/3 because of the keep, change, flip rule.

21/21 simplifies to 1/1

1/1 = 1

The sum of three numbers is -2. The sum of three times the first number, twice the second number, and the third number is nine.

Anna35 [415]

Answer:

The numbers are 3, 5, -10.

Step-by-step explanation:

Let, the numbers are X, Y, Z.

Given, sum of the three numbers are -2.

So, the equation is X + Y+ Z = -2 .......(i)

Again, for 2nd condition, the equation will be

3X + 2Y + Z = 9 ....... (ii)

Again, for the third condition, the equation will be

Y - (Z/2) = 10 ......(iii)

Multiplying the equation (i) by 3 and the equation (ii) by 1, we get

3X + 3Y+ 3Z = -6

(Deduct) Y + 2Z = -15 ......(iv)

Solving equation (iii) and (iv) we get,

Y - (Z/2) = 10

(Deduct) -(Z/2) - 2Z = 25

or, (-Z-4Z)/2 = 25

or, -5Z = 25*2

or, Z = 50/(-5)

Therefore, Z = -10

Putting the value of Z into equation (iv) we get,

Y + 2*(-10) = -15

or, Y - 20 = -15

or, Y = 20 - 15

Therefore, Y = 5

Putting the value of Y and Z into equation (i) we get,

X + 5 + (-10) = -2

or, X + 5 - 10 = -2

or, X - 5 = -2

or, X = 5 - 2

Therefore, X = 3

So, the numbers are, X = 3; Y = 5; and Z = -10.
