The equation 3.3x - 6.6 = 2.7x is equal to the expression 0.6x = 6.6 (2nd option)
The equation a = 100 + 75d represents Maria's account balance.
<u>Step-by-step explanation:</u>
Given that,
- Maria opened a new savings account with an initial deposit of $100.
- She deposits $75 into this savings account every two-weeks.
You need to find the equation to represent Maria's account balance, a after she has completed d deposits.
- Let 'd' be the number of deposits Maria made after the initial deposit.
- Let 'a' be the total account balance after 'd' deposits.
Therefore, the equation for the total account balance can be framed as the sum of the initial deposit and amount deposited after that.
<u>To find the amount that was deposited after the initial deposit :</u>
⇒ $75 × number of times Maria deposited.
⇒ 75 × d
The equation is written as,
⇒ a = 100 + 75d
Hence the equation a = 100 + 75d represents Maria's account balance.
Answer:
Height = 5 and Base = 10
Step-by-step explanation:
The base of the parallelogram is twice the perpendicular height of the parallelogram. The area of the parallelogram is 50 cm².
Formula for area of parallelogram = base × height
Base = 2h
Height = h
∴ Area = 2h × h = 50
Solution:
2h × h = 50
2h² = 50
h² = 25
h = 5
∴ height = 5 and base = 2(5) = 10
5(x+3)=3(2x-1)
**distribute
5x+15=6x-3
-5x -5x
**get like term together
15=x-3
+3 +3
**get x alone on one side of the equation
18=x
check your work by replacing the variable x with 18
5(18+3)=3(2·18 -1)
5·21=3·35
105=105 yes!
So, the number you are looking for is 18
