Value of (–3/8) × (+8/15). <br><br> A. 11/15<br> B. 11/23<br> C. –1/5<br> D. –1/3
svet-max [94.6K]

ANSWER

The correct answer is C

EXPLANATION

We want to find the value of

- \frac{3}{8}   \times  \frac{8}{15}

This is the same as:

-  \frac{3}{8}  \times  \frac{8}{3 \times 5}

We cancel out the common factors to get:

-  \frac{1}{1}  \times  \frac{1}{1 \times 5}

We simplify to get:

-  \frac{1}{5}

The correct answer is C

Does the table represent a function? Why or why not?
Vinvika [58]

Answer:

Let's put the chart into ordered pairs:

(x, y)

(2,1)

(3,4)

(3,3)

(4,2)

(5,5)

In bold, we see that there are two y-values at x=3. This means that this relation fails the vertical line test (two points on the same verticle line). This is not a function. 

The answer options may be mis-written. 

The answer is no, because one x value corresponds to more than one y-value.

What is the answer of the equation 2(x+2)-7+x=27
mylen [45]

Answer:

x = 10

Step-by-step explanation:

Solve for x:

2 (x + 2) - 7 + x = 27

2 (x + 2) = 2 x + 4:

2 x + 4 + x - 7 = 27

Grouping like terms, 2 x + x - 7 + 4 = (2 x + x) + (4 - 7):

(2 x + x) + (4 - 7) = 27

2 x + x = 3 x:

3 x + (4 - 7) = 27

4 - 7 = -3:

3 x + -3 = 27

Add 3 to both sides:

3 x + (3 - 3) = 3 + 27

3 - 3 = 0:

3 x = 27 + 3

27 + 3 = 30:

3 x = 30

Divide both sides of 3 x = 30 by 3:

(3 x)/3 = 30/3

3/3 = 1:

x = 30/3

The gcd of 30 and 3 is 3, so 30/3 = (3×10)/(3×1) = 3/3×10 = 10:

Answer:  x = 10
