$217.98. 

First, add the beginning balance of $98 to each of the deposits ($34.98, $51.02, $51.22) to get $235.22. 

Next, subtract each of the withdrawals ($3.23, $4.22, $9.79) from this total to get the ending balance of $217.98. 

Here, it's important to understand which amounts are withdrawals and which are deposits. Classifying the amounts correctly will tell you to subtract withdrawals and add deposits to the beginning balance. This ending balance will become your beginning balance for the next month.

Step-by-step explanation:

<u>Step 1: Define</u>

-15x + 5 = -10x + 25

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Add 15x on both sides:                    5 = 5x + 25
  2. Subtract 25 on both sides:              -20 = 5x
  3. Divide 5 on both sides:                   -4 = x
  4. Rewrite:                                             x = -4

Tomas is making trail mix using granola and walnuts. He can spend a total of $12 on the ingredients. He buys 3 pounds of
spin [16.1K]

Answer:

The first error that Tomas made was added 6 to both sides of the equation instead of subtracting 6

Step-by-step explanation:

Let

x ----> represents the number of pounds of granola

y ----> represents the number of pounds of walnuts

we know that

The linear equation that represent this scenario is

2x+6y=12 -----> equation A

x=3 -----> equation B

substitute equation B in equation A and solve for y

2(3)+6y=12

6+6y=12

Subtract 6 both sides

6+6y-6=12-6

6y=6

Divide by 6 both sides

6y/6=6/6

y=1

so

The number of pounds of walnuts is 1

therefore

The first error that Tomas made was added 6 to both sides of the equation instead of subtracting 6
