Answer:

I think the answer is 5 + -4.

Step-by-step explanation:

That's because 5-4 is 1. And 5 + -4 is also 1. 5 + -4 reversed is 5 - 4 (you change the symbol and channge the last number from negative to positive or positive to negative). Sorry if this doesn't make sense or is wrong :3

A 185-pound person burns 260 calories during a soccer game. Find the number of calories that a 250-pound person would burn durin

Olin [163]

Answer: The answer to this problem is 178 calories.

Step-by-step explanation:

To calculate the answer, simply get the percentage of calories a person would burn during exercise (I am using a calculator BTW).

185 / 260 = 0.711538462

Then, calculate 71.1538462% of 250 pounds.

250 * 0.711538462 = 177.884616

Finally, round up your answer. 177.884616 rounded up is 178.

Help please!!! Thank you

Given:

The given expression is $\frac{4 d+28}{12 d+96} \cdot \frac{d^{2}+14 d+48}{d^{2}+9 d+14}$

We need to multiply the terms.

Multiplication of the terms:

Before multiplying the terms, first we shall find the factors of the quadratic equations.

Thus, we have;

$\frac{4 d+28}{12 d+96} \cdot \frac{(d+6)(d+8)}{(d+2)(d+7)}$

Factor out the common terms, we get;

$\frac{4 (d+7)}{12 (d+8)} \cdot \frac{(d+6)(d+8)}{(d+2)(d+7)}$

Let us cancel the common terms from the above expression.

Thus, we have;

$\frac{4 }{12 } \cdot \frac{(d+6)}{(d+2)}$

Simplifying, the term, we get;

$\frac{1}{3 } \cdot \frac{(d+6)}{(d+2)}$

Now, we shall multiply the terms.

Hence, multiplying the terms, we get;

$\frac{(d+6)}{3(d+2)}$

Thus, the multiplied value of the given expression is $\frac{(d+6)}{3(d+2)}$

Answer:

A , and C

Step-by-step explanation:

A. 2.3+(-2.3) ➡ 2.3 -2.3 = 0 so this option is correct

B.-3.7+(-4.1) ➡ -3.7 - 4.1 = -7.8 so this option isn't correct

C.-2.6-(-12/4) ➡-2.6 + 3 = 0.4 this option is also correct

D. (5/2)+(-2.5) ➡ 5/2 -5/2 = 0 this one would be undefined because we can't divide 0 by 2 or any other rational numbers

E.72-(-100) ➡72+100= 172 is positive not negative therefore this option is incorrect
