the answer is x = 9/2

explanation

3 (x - 2) = 7 – (4 - x)

apply the distributive law to 3(x - 2)

to get 3x - 6

simplify 7-(4-x)

3 + x

you now have

3x - 6 = x + 3

add 6 to both sides

<u>-6+6=0</u>   <u>3 + 6 = 9</u>

3x=x+9

subtract x from both sides

<u>3x - x = 2x  </u>   <u>x - x = 0</u>

2x = 9

divide both sides by 2

2x/2 = x    9/2

to get x = 9/2

Searches related to Anita needs 5 pounds of bananas to make banana bread for a bake sale. Each pond of bananas cost 0.50. How ca
m_a_m_a [10]

Answer:

$2.5

Step-by-step explanation:

Number of pounds of banana needed = 5 pounds

Cost per pound of banana = 0.50

To solve using place value blocks :

Ignoring the decimal in the cost per pound:

We can first take the product of 5 (Number of pounds of banana) and take cost per pound as 5. Since it is easier to make direct multiplication without decimal.

5 * 5 = $25

Now we can add the one decimal point (in the cost per pound) to our result

Then we have $2.5

Hence, total cost = $2.5
