1/8 + 1/4

the least common multiple of 8 and 4 is 8. Convert 1/8 and 1/4 to fractions with denominator 8.

1/8 + 2/8

Because 1/8 and 2/8 have the same denominator, add them by adding their numerators.

1+2/8

add 1 and 2 to get 3

3/8 or 0.375

What is the solution to −1/4(d+1)<2

kogti [31]

Answer:

$d > -9$

Step-by-step explanation:

$-\dfrac{1}{4}(d + 1) < 2$

First, multiply both sides by -4. You must also change the inequality sign since you are multiplying both sides by a negative number.

$-4 \times \left(-\dfrac{1}{4}\right)(d + 1) > 2 \times (-4)$

$d + 1 > -8$

Subtract 1 from both sides.

$d + 1 - 1 > -8 - 1$

$d > -9$

The endpoints of a line segment are at the coordinates (–6, 3, 4) and (4, –1, 2). What is the midpoint of the segment?

natulia [17]

Answer:

$( - 1,1,3 )$

Step-by-step explanation:

Use the midpoint formula:

$(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}, \frac{z_1+z_2}{2} )$

We want to find the midpoint of the line

that has endpoints.

$(\frac{ - 6+4}{2},\frac{3+ - 1}{2}, \frac{4+2}{2} )$

We simplify to get;

$(\frac{ - 2}{2},\frac{2}{2}, \frac{6}{2} )$

This finally gives:

$( - 1,1,3 )$

The correct answer is A.
