Answer:

c is 30.

The angles, from left to right, are:

66, 94, and 20.

Step-by-step explanation:

The three angles form a straight angle. In other words, they sum to 180. So, we can write the following equation:

(2c+6)+(3c+4)+(\frac{1}{2}c+5)=180

Let's solve for c. Combine like terms:

(2c+3c+0.5c)+(6+4+5)=180

Add:

5.5c+15=180

Subtract 15 from both sides:

5.5c=165

Divide both sides by 5.5:

c=30

So, the value of c is 30.

Now, substitute it into each of the angles to find their respective measures.

Left-Most Angle:

We have:

2c+6

Substitute 30 for c. This yields:

=2(30)+6

Multiply and add:

=60+6=66

Middle Angle:

We have:

3c+4

Substitute 30 for c:

=3(30)+4

Multiply and add:

=90+4=94

Right-Most Angle:

We have:

\frac{1}{2}c+5

Substitute 30 for c:

=\frac{1}{2}(30)+5

Multiply and add:

=15+5=20

So, our angles, from left to right, are: 66, 94, and 20.

And the value of c is 30.

And we're done!

24x+7=79<br> help? have to get x by itself, right?
andrey2020 [161]
24x + 7=79
subtract 7 from both sides
24x + 7 - 7= 79 - 7
24x= 72
divide both sides by 24
x= 3

CHECK:
24x + 7= 79
24(3) + 7= 79
72 + 7= 79
79= 79

ANSWER: x= 3

Hope this helps! :)

Answer:

D or answer 4                   y=-5/2x+7

Step-by-step explanation:

Well we can first start of by finding the y-intercept.

Note that when x=0, you can find your y-intercept.

Knowing this, and looking at the table, 7 is the y-intercept because when y=7, x=0.

So we can eliminate choices 'a' and 'c,' or answers 1 and 3, because they have the y-intercept as -7, when it's just 7.

Please know that in the equation:

y = mx + b

y = y-coordinate or any given point

mx = slope

b = y-intercept

Now we must find slope

To find the slope we need to do:

(y2 - y1) / (x2 - x1) or rise/run

The two coordinates I choose to use is (0, 7) and (6, -8).

(-8 - 7) / (6 - 0) = -5/2

-5/2 is the slope

Finally, look for an equation that has 7 as the y-intercept and -5/2 as the slope.

Answer: D or answer 4

Hi, I need help.
slavikrds [6]

Answer:

B, 24 (second answer choice)

Step-by-step explanation:

4r+7s=23

r-2s=17

8r+14s=46

7r-14s=119

15r=165

r=11

11-2s=17..........by putting value of r in ii

-2s=17-11

2s= -6

s= -3

3r+3s=3*11+3(-3) you get this by putting values of r and s

       =33-9

       =24    (B)
