Hello!
I would be more than happy to help!
So to find the balance use this equation.
Balance = Credit- Debit
In other words, to find BALANCE... You Subtract Debit from Credit
whats my credit? 84$
Whats my debit? 29$
Whats my balance? Lets find out! How? Well, lets subtract my credit (84) from my debit (29).
84-29= 55
Balance =55
Hope this helped!
Lynn age: 7x+2. That's if you wanted an equation.
C because it is and I am in 12 grade I no this
Answer:
3 dimes
Step-by-step explanation:
Part A: 0.10x + 0.25 = 0.80 (dimes are 10 cents or 0.10 dollars, quarters are 0.25 dollars)
Part B: Plug in what you DO know and solve the one you DON’T:
0.10x + 0.25(2) = 0.80
0.10x + 0.50 = 0.80. Subtract 0.50 from both sides:
0.10x = 0.30 (Divide both sides by 0.10)
x = 3
3 - 2a > 7
We need to solve for a
First, let's subtract 3 on both sides to have the variables on a side and the numbers on another side:
3 - 2a > 7
3 - 2a - 3 > 7 - 3
- 2a > 4
Let's divide both sides by -2 to have a on side and its value on the other side:
-2a > 4
(-2a)/(-2) > (4/-2)
a < -2 (In a case of an inequality, we change the sign when we divide by a negative number to its opposite).
So 3 - 2a > 7 when a < -2 (answer c)
Hope this helps! :D
