Solve the proportion what y = ?

The correct answer should 3, but there's no option!

Hey there!

“Simplify: –7 + 17 – 7”

“A. 31”

“B. –17”

“C. –3”

“D.17”

–7 + 17 – 7 =

–7 + 17 = 10

10 – 7 = 3

Your answer SHOULD be: 3 ☑️

(Closest to your answer would be: Option C. –3)

Good luck on your assignment and enjoy your day!

Answer:

(1/2) ( 5 - 7x)  = 8 - 4x - 6

(1/2) (5 - 7x)  = 2 - 4x    multipy through by 2

5 - 7x   = 4 - 8x         add 8x  to both sides.......subtract 5 from both sides

x = -1

Answer:

A: -1/3x

Step-by-step explanation:

We can convert -1/3 to -2/6 by multiplying -1/3 by 2/2. As we know, 5-2 is 3. That makes 3/6. 3/6 is equivalent to 1/2. That means it has to be A.

Answer:

Spelling word questions = 10

vocabulary word questions = 16

Step-by-step explanation:

Let

Spelling word questions = x

vocabulary word questions = y

Total points = 100

Total questions = 26

x + y = 26 (1)

2x + 5y = 100 (2)

From (1)

x = 26 - y

Substitute x = 26 - y into

2x + 5y = 100

2(26 - y) + 5y = 100

52 - 2y + 5y = 100

- 2y + 5y = 100 - 52

3y = 48

y = 48 / 3

= 16

y = 16

Substitute y = 16 into

x + y = 26

x + 16 = 26

x = 26 - 16

= 10

x = 10

Spelling word questions = 10

vocabulary word questions = 16

Answer:

5

Step-by-step explanation:

The average (mean) is equal to the sum of all the data values divided by the number of values in the data set.

Mean = Sum / Count

Mean = (2+4+5+6+8) / 5

Mean = 25 / 5

Mean = 5

The average mean of the given data will be "5". A further solution is provided below.

The given data is:

→ [tex]2,4,5,6,8[/tex]

Total number of data value,

= 5

The mean will be:

= [tex]\frac{Sum \ of \ all \ data \ values}{Number \ of \ data \ values}[/tex]

By substituting the given values, we get

= [tex]\frac{2+4+5+6+8}{5}[/tex]

= [tex]\frac{25}{5}[/tex]

= [tex]5[/tex]

Thus the above is the correct answer.

Answer: -1t + 720

Step-by-step explanation:

He worked at both jobs for 90 hours for this month.

He worked t hours as a tutor which means that as a waiter he worked;

= 90 - t hours

The amount earned is therefore;

= 7t + (8 * (90 - t))

= 7t + 720 - 8t

= -1t + 720

Answer:

C = 48.5° ; B = 131.5°

Step-by-step explanation:

When any two angles are supplementary , it means that their sum is equal to 180°.

It's given in the question that B is 83 more than C . So,

[tex]B = C + 83[/tex]

Also it's given in the question that B & C are supplementary angles.

[tex]=> B + C = 180[/tex]

[tex]=> C + 83 + C = 180[/tex]

[tex]=> 2C = 180 - 83 = 97[/tex]

[tex]=> C = \frac{97}{2} = 48.5[/tex]

Hence,

[tex]B = 83 + 48.5 = 131.5[/tex]

∴ C = 48.5° ; B = 131.5°

Answer:

y+8=-5(x-3)

Step-by-step explanation:

The formula for point-slope form is y-y1=m(x-x1)

The points for (x1, y1) are (3, -8), meaning that 3 is x1 and -8 is y1.

So, start by writing your equation like this: y--8=m(x-3)

For the equation y--8=m(x-3), the y--8 will change to a + sign because two negatives make a positive, right? So, the equation should now look like this: y+8=m(x-3).

We know that the slope (m) is -5. Plug that into the equation to get this: y+8=-5(x-3)

And there you have it!! The equation is now in point-slope form!!

y+8=-5(x-3) is the final answer!!
