6. Find the possible values of n in the inequality –3n < 81. A. n > –27 B. n < 27 C. n = –27 D. n = 27

evablogger [386]

-3n < 81...divide both sides by -3, change the inequality sign
n > -81/3
n > - 27 <==

** in an inequality, when dividing/multiplying by a negative number, the inequality sign changes

What is the value of x in the equation one-fifthx – two-thirdsy = 30, when y = 15? 4 8 80 200

vova2212 [387]

Answer:

x = 200

Step-by-step explanation:

Given

$\frac{1}{5}$ x - $\frac{2}{3}$ y = 30 ← substitute y = 15 into the equation

$\frac{1}{5}$ x - $\frac{2}{3}$ × 15 = 30 , that is

$\frac{1}{5}$ x - 10 = 30 ( add 10 to both sides )

$\frac{1}{5}$ x = 40 ( multiply both sides by 5 to clear the fraction )

x = 200

-GEOMETRY PROBLEM- I don’t understand this problem, can anybody help? The question is in the picture. Thanks! I’ll give 15 point

In tue picture, we can see 2 triangles and they already labeled 2 congruent sides. We also see that the line in the middle is being shared between the 2 triangles, making the side equal. Using the SSS theorem, we can prove that these teiangles are congruent to each other. Hope this helps.

Please help! im doing a test right now

Answer:

a.) Time = 6 hours

b.) Average Speed = 410 miles per hours

c.) Distance = 196 miles

Step-by-step explanation:

<h3><u>a.</u>)</h3>

A coach drives 360 miles at a speed of 60 mph.

So,

Time = Distance ÷ Speed

Time = 360 ÷ 60

Time = 6 hours

<h3><u>b.</u>)</h3>

A plan flies 1640 miles in 4 hours.

So,

Average Speed = Distance ÷ Time

Average Speed = 1640 ÷ 4

Average Speed = 410 miles per hours

<h3><u>c.</u>)</h3>

A bus drives 3½ hour at an average Speed of 56 mph.

So,

3½ hour = 3.5 hour

Distance = Average Speed × Time

Distance = 56 × 3.5

Distance = 196 miles

What is 328.618 round to the nearest hundredth<br><br>A. 300<br>B. 328.60<br>C. 330<br>D. 328.62

son4ous [18]

Answer:

D. 328.62

Step-by-step explanation:

328.618 round to the nearest hundredth

Rounding to the nearest hundredth means 2 numbers after the decimal point

Numbers that rounds to 1 are 5, 6, 7, 8, 9

Number that rounds to 0 are 0, 1, 2, 3, 4

When rounding up, to the nearest hundredth, you will consider the next number after the two figures after the decimal point

Here, the next number after the two figures after the decimal point is 8

8 is a number that rounds to 1

Therefore, add 1 to 1 to have
