Answer:
C = 20
Step-by-step explanation:
What happens if simultaneous Equations have two of the same variable like below? How would I solve it?
6A + 4B + 5C = 390
6A + 4B + 5.75C = 405
Step 1
We solve for C first
6A + 4B + 5C = 390....Equation 1
6A + 4B + 5.75C = 405... Equation 2
We substract Equation 1 from Equation 2
0.75C = 15
C = 15/0.75
C = 20

- Sum of Angles: 180(n - 2)
Step-by-step explanation:
<u>Step 1: Define</u>
Number of sides <em>n</em> = 10
<u>Step 2: Find</u>
- Substitute: 180(10 - 2)
- Subtract: 180(8)
- Multiply: 1440°
<u>Step 3: Find 1 angle</u>
<em>We have 10 sides.</em>
- Divide: 1440/10 = 144
So look:
1) 20 cm by 20 cm by 6 cm
2) 40 cm by 30 cm by 2 cm
Hope this helps!
Answer: 2.0
Step-by-step explanation:
The given expression : 
To solve the given expression , we need to follow BODMAS (Bracket→ Of Divide→ Multiplication →Add →Subtract).
According to BODMAS , first we simplified the expression present inside the brackets .
[10= LCM[10,5]]
[Multiply]
[Simplify]
[Add]
Hence, the value of the expression in the simplified form = 2.0
