7x+3(8x+7) distributive property

Answer:

Step-by-step explanation:

#1. Find the least common denominators

#2. 1 and 7/20 hours

#3. 5/12

#4.  9/10

#5. 19/25

Answer:

1, C,

2, 1 7/20

3, 7/12

4, 9/10

5, 19/25

Step-by-step explanation:

1, You need to find LCD for every fraction add or subtract question

2, 3/4 + 6/10.

LCD: 20,

4 x 5=20 and times 3 by 5 to get 15 (15/20),

10 x 2 =20 and 6 times 2 to get 12 (12/20).

Now you may add them together which is 12/20 + 15/20= 27/20, simplify:

1 7/20

3, 1/6 + 1/4.

LCD: 12

6 x 2= 12, 1 x 2=2 (2/12)

4 x 3= 12, 1 x 3=3 (3/12)

add, now 5/12

the whole was 12/12 of pie so now subtract

12/12 - 5/12= 7/12

4, 1/6 + 2/5 + 1/3.

LCD: 30

6 x 5=30, 1 x 5= 5 (5/30)

5 x 6= 30, 2 x 6=12 (12/30)

3 x 10= 30, 1 x 10= 10 (10/30)

add, 5 + 12 + 10= 27 (27/30)

simplify: 9/10

5, 14/25 + 1/5.

LCD: 25

14/25 (stay still)

5 x 5=25, 1 x 5= 5 (5/25)

add, 15 + 4 = 19 (19/25)

Answer:

( - 2 - 5m ) / 3

Step-by-step explanation:

15m + 9n = - 6

9n = - 6 - 15m

Divide by 3 on both sides,

9n / 3 = - 6 / 3 - 15m / 3

3n = - 2 - 5m

n = ( - 2 - 5m ) / 3

Answer:

[tex]15m + 9n = - 6 \\ 9n = 15m - 6 \\ n = \frac{15m - 6}{9} \\ \\ n = \frac{15m - 2}{3} [/tex]

D. y + 7 = -6/5(x + 3)

Step-by-step explanation:

Answer:

B. y + 7 = -6/5 (x+3)

Step-by-step explanation:

Use the given slope and point to substitute into the point-slope formula  y − y 1 = m ( x − x 1 ) .

Slope-intercept form:  y = − 6 /5 x − 53 /5

Point-slope form:  y + 7 = − 6 /5 ⋅ ( x + 3 )

Answer:

x=111ft

Step-by-step

sin 24 = 45/x

+ the parallel lines

45 +x+24

x= 45/sin 24

The actual distance of your from the stage is 111 feet.

The angle formed by the line of sight and the horizontal plane for an object below the horizontal is called angle of depression.

The sine (sin) of an acute angle in a right angled triangle is the ratio between the side opposite the angle and the hypotenuse of the triangle.

According to the given question

We have

Angle of depression = 24degrees.

Let d be the actual distance of your from the stage.

Now in right angle triangle ABC

We have

AC = 45 feet

And, ∠ABC = 24 degrees

Now the Sine of an angle ∠ABC is given by

[tex]sin24 = \frac{AC}{AB}[/tex]

⇒[tex]sin24=\frac{45}{d}[/tex]

⇒ [tex]0.406=\frac{45}{d}[/tex]

⇒ [tex]d =\frac{45}{0.406}[/tex]

⇒[tex]d = 110.64 feet[/tex] or [tex]111feet[/tex]

Hence, the actual distance of your from the stage is 111 feet.

Answer:

  10. needs work

  11. correct

  12. correct

  13. correct

Step-by-step explanation:

In general, it is a good idea to write a statement that answers the question asked. Simply solving an inequality for "x" rarely answers the question (unless it is a question that asks for the value of "x"). It is often best to try to use the wording that the question uses.

It is also a good idea to say what your variable represents.

__

The required relation is "cheaper than" so the "or equal to" case does not apply. The variable represents messages, so the solutions will be integers.

  "Nadine can send and receive more than 33 messages so the unlimited plan is cheaper."

__

"Becky can afford at most 8 fish."

__

"Loretta must drive more than 260 miles farther to reach Pensacola."

__

"Terri can spend at most 35 minutes listening to music."

_____

Additional comment

The wording of the question in problem 10 is unconventional, but we have elected to use it anyway in the above answer. We could write "The unlimited plan is cheaper if Nadine sends and receives a total of more than 33 messages."

-0.15

Step-by-step explanation:

[tex]\frac{y{2}- y{1} }{x{2}-x{1} }\\[/tex]      is the formula

now let's subsitute into the formula with our points (6,10) and (-20,14)

[tex]\frac{14-10=4}{-20-6=-26}[/tex]

now we have the fraction [tex]\frac{4}{-26}[/tex]     or -0.15

Answer:

The answer is the last one or the one on the very bottom because y is above and touching the line so y must be greater than or equal to the slope plus the y-intercept or b. I figured out the slope by using rise over run meaning that you must first go up or down on a coordinate and then go left or right to meet the other coordinate. The y-intercept is just the place where the line touches the y axis and that is on -1. By piecing up these pieces of information one by one you will get D or the last one.
