Let's assign each a variable:
Computer: 3x
Printer: x
We know that the total is 1136, so:
x+3x=1136
4x=1136
Now, we divide 1136 by 4 to get the cost of the printer.
1136/4=284
So, now let's apply this to what we wrote previously.
Answer:
Printer: 284
Computer: 284*3= 852

Answer:
₹245 is the cost
Step-by-step explanation:
Given:
Cost of the fan = ₹1470
1/6th = 1470/1 × 1/6
(do not cross multiply and simplify)
= ₹245
Answer:
x = 10
I used the Interior Angles of a Triangle Rule --The sum of all 3 interior angles in a triangle is always 180°.
(3x + 28) + (5x - 18) + 90° = 180°
Now i can get rid of the parentheses and combine like terms.
3x + 5x + 28 - 18 + 90 = 180
8x + 10 + 90 = 180
8x + 100 = 180
Then i subtract 100 from both sides to isolate x.
8x + 100 - 100 = 180 - 100
8x = 80
Then, i divide both sides by 8 to find x.
8x ÷ 8 = 80 ÷ 8
x = 10
