Sandra used her debit card to buy lunch for $8.74 on Monday. On Tuesday, she deposited $8.74 back into her account. What is the overall increase or decrease in her bank account?

Answers

Answer:

$0$

Step-by-step explanation:

Money spent by Sandra on Monday to buy lunch using her debit card is $\$8.74$

Money deposited by Sandra into her bank on Tuesday is $\$8.74$

Difference of both transactions $8.74 - 8.74 = 0$

∴ Overall increase or decrease in Sandra's bank account after both transaction is $0$

i.e no overall increase or decrease in her bank account

-8.74 + 8.74 = 0....there is a 0 increase/decrease in her account

The solution of the equation is x= .

Answer:

$x=1$

Step-by-step explanation:

Step 1: Cross-Multiply

What cross multiply basically means is that you take both sides of the equation and you multiply my the opposite sides. So you take the top of the left fraction and multiply it by the bottom of the right fraction. You then have an equal sign and then have the bottom of the left fraction multiplied by the top of the right fraction.

$(2)/(7)=(6x)/(4x+17)$

$2(4x+17)=7(6x)$

Step 2: Distribute

$2(4x+17)=7(6x)$

$(2*4x)+(2*17)=(7*6x)$

$8x+34=42x$

Step 3: Subtract 8x from both sides

$8x + 34- 8x = 42x - 8x$

$34=34x$

Step 4: Divide both sides by 34

$34/34 = 34x/34$

$1=x$

Answer: $x=1$
