Problem 8

Answer: angle LSO and angle MSN

--------------

Explanation:

Vertical angles form when we intersect two line segments, lines, or rays. Vertical angles are opposite one another and they are always congruent.

=============================================

Problem 9

Answer: angle LMS and angle SMN

--------------

Explanation:

Adjacent angles share a common line, line segment, or ray. Think of two adjacent rooms sharing a common wall between them. In the case of the answer above, the two angles share the common segment SM (note how S and M are part of LMS and SMN)

When it comes to naming angles, the middle letter is always the vertex of the angle. This is the hinge so to speak. Or you could picture a pair of scissors. For angle LMS, the arms LM and SM are the two blades of the scissors while point M is where the blades meet.

=============================================

Problem 10

Answer: angle LSM and angle MSN

--------------

Explanation:

Same idea as problem 9. Now we're making S the middle letter. Something like angle LSM is the same as angle MSL.

In this case, the two adjacent angles form a straight line. We consider these two angles a linear pair.

=============================================

Problem 11

Answer: angle LSO and angle OSN

--------------

Explanation:

The term linear pair was discussed back in problem 10. So you could list those two angles again, or you could go with another pair as shown above. All that matters is that they are adjacent angles and they are supplementary angles (they add to 180 degrees). There are many possible answers.

Something like the angle pair angle LOS and angle NOS are adjacent angles, but they aren't supplementary. So we don't meet the condition of a linear pair here.

What is the difference of 23x and 9x?

BaLLatris [955]

Subtract 9x from 23x yields 14x. This was done by subtracting algebraically the variables.

−20 ≤ 59(F−32) ≤ −15

lubasha [3.4K]

We take the value of F in the inequality by taking the inequalities in group. Let the first group be:

(1) -20 ≤ 59(F - 32)

Then, the second group would be,
(2) 59(F - 32) ≤ - 15

Calculating for the values of F,

(1) -20 ≤ 59F - 1888
1888 - 20 ≤ 59F
1868 ≤ 59F
F ≥ 31.66

(2) (59)(F - 32) ≤ - 15
59F - 1888 ≤ -15
59F ≤ 1873
F ≤ 31.75

The values of F are therefore,
31.66 ≤ F ≤ 31.75

chanasia has a point 75 gallons of paint. She wants to use to 2/5 of the paint to pay her living room. How many gallons of paint

Brut [27]

To find this, we simply multiply 75 by 2/5

75 * 2/5 = 75*2/5

150/5 = 30

She will use 30 gallons of paint.

Hannah got a perfect score on 3 more spelling quizzes this quarter than last quarter . If she doubles the number of perfect quiz

algol13

First, underline the key numbers

n=Perfect Quizzes last quarter

x=School record

n+3

3•2=x

Now we solve that

3•2=6

Now we know, x=6

If the record (6) is 3 times the number of spelling quizzes Hannah scored perfectly last quarter (n), then we know we have to divide the record (6) by 3 to know how many perfect quizzes were from last quarter.

6/3=2 so, n=2

The number of perfectly scored quizzes from last quarter is 2.
