Answer:
180/147
Step-by-step explanation:
We need to find the additive inverse of the given numbers.
- For finding it we may simply out -1 as multiplication in front of the terms .
<u>SOLUTION</u><u> </u><u>1</u><u> </u><u>:</u><u>-</u>
→ 3/-7 - 11/21
→ -3/7 -11/21
→ 3×-3 - 11 /21
→ -9-11/21
→ -20/21
<u>SOLUTION</u><u> </u><u>2</u><u> </u><u>:</u><u>-</u><u> </u>
→ 9/5 ÷ 7/5
→ 9/5 × 5/7
→ 9/7
→ Product of nos . = -20/21 × -9/7
→ Ans = 180/147
Answer:
Step-by-step explanation:
Arc length of the circle is given by,
Arc length =
Area of the sector of a circle =
22). Arc length of the circle having central angle =
= 60°
Arc length =
=
= 7.33 cm
23). Arc length of the circle having central angle = 225°
Arc length =
= 12.5π
= 39.27 km
24). Central angle =
=
= 225°
Area of the sector =
= 43.20 yd²
25). Area of the sector =
= 65.97 yd²
The chances of getting 6 on a six-sided die are 1/6, therefore the first one is correct.
Answer:
x -2 = 3x +2
Step-by-step explanation:
For the purpose, we use math symbols to express the relation described by the English.
<h3>Translation</h3>
When x represents "a number," we have ...
- two less than a number: x -2
- the product of 3 and the number: 3x
- 2 more than the product: 3x +2
- is the same as: =
Then the English description can be translated to ...
x -2 = 3x +2
__
<em>Additional comment</em>
Adding -2-x to both sides gives ...
-4 = 2x
-2 = x . . . . . divide by 2
The number is -2.
