Answer:
-7 degrees
Step-by-step explanation:
-28 divided by 4 equals -7. -7 x 4 = -28
19/15 = 1 4/15
1 and 4/15
Answer: 1 and 4/15
As a decimal ...
1.29 repeating 9
As d=k t^2 so putting d= 192 for t =8 we get k= 192/(8^2) =3 so k=3
thus d = 3t^2
now if t=6 the d = 3*(6^2) = 3*36
so d = 108
Answer: 31.5
Concept:
When encounter questions that ask for operation on algebraic expressions, using BODMAS or PEMDAS method would be easier. Since this question asked for using BODMAS, then it is:
- Bracket
- Order
- Division
- Multiplication
- Addition
- Subtraction
Solve:
<u>Given</u>
2 × 3 + 45 ÷ 2 - 6 + 9
<u>Simplify by division</u>
=2 × 3 + 22.5 - 6 + 9
<u>Simplify by multiplication</u>
=6 + 22.5 - 6 + 9
<u>Simplify by addition</u>
=28.5 + 9 - 6
=37.5 - 6
<u>Simplify by subtraction</u>
=31.5
Hope this helps!! :)
