What is the value of 2 + (- 12=1? -2 16 031

Mathematics
1 answer:
Gwar [14]2 years ago
3 0

Answer:

\boxed{\boxed{\tt B)-2}}

Step-by-step explanation:

\tt 2+\left(-\cfrac{2}{3}\right)2\div \cfrac{1}{3}

Express -2/3 × 2 as a single fraction:

\tt 2+\cfrac{\cfrac{-2\times 2}{3} }{\cfrac{1}{3} }

Multiply -2 × 2 = -4

\tt 2+\cfrac{\cfrac{-4}{3} }{\cfrac{1}{3} }

Now, rewrite fraction \tt \frac{-4}{3} as \tt -\frac{4}{3} by extracting the (-) sign:

\tt 2+\cfrac{-\cfrac{4}{3} }{\cfrac{1}{3} }

Divide - 4/3 by 1/3 by multiplying - 4/3 by the reciprocal → 1/3

\tt 2-\cfrac{4}{3} \times 3

Cancel out 3 and 3:

\tt 2-4

Subtract numbers:

\tt -2

1. Jemima wants to make chocolate chip walnut brownles. Chocolate chips come in a 12oz bag that costs $3. Walnuts
fomenos

Answer:

4 bags of chocolate chips and 1 bag of walnuts.

Step-by-step explanation:

Find how many ounces are in 3 pounds:

16 oz = 1 lb

16 oz × 3 = 3 lbs

48 oz = 3 lbs

Variable x = number of chocolate chips

Variable y = number of walnuts

4x + 1y = 15

Keep in mind it must equal up to 48 oz and be $15 or under.

4 bags × 12 oz = 48 oz

1 bag × 4 oz = 4 oz

48 oz + 4 oz = 52 oz > 48 oz

4 bags × $3 = $12

1 bag × $2 = $2

$12 + $2 = $14 < $15

Both requirements have been met.

Which of the following is not represented by the image below
love history [14]

Answer:

Line BD can't be represent by the image.

Explanation:

Point: Point is a dot or vertex of any figure or diagram. It represent by capital alphabet. So, B would be a point.

Line: A line is a straight path with both endless. It means we can extends line from both end. But in case of BD we can't extend from point B. So, it won't be line.

Ray: A ray is straight path with one endless. It means we can't extend line from one end and extend from another end. But we can extend AC from both end. It won't be a ray.

Line Segment: A line segement is straight path with end from both end. We can't extend from either end of the line. We can say CD would be line segment.

Option 2 is correct.
