Use the numbers below to simplify the expression. Numbers may be used once or not at all. 34671011 3y + 7 + 4y + 3 = y +

Svetllana [295]

Answer:

$3y + 7 + 4y + 3 = 7y + 10$

Step-by-step explanation:

Given

$3y + 7 + 4y + 3 = [\ ]y + [\ ]$

Required

Simplify

We have:

$3y + 7 + 4y + 3$

Collect like terms

$3y + 7 + 4y + 3 = 3y + 4y + 7 + 3$

Evaluate like terms

$3y + 7 + 4y + 3 = 7y + 10$

Question 7: Which of the following statements is true?

yawa3891 [41]

Problem 7)

The answer is choice B. Only graph 2 contains an Euler circuit.

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

To have a Euler circuit, each vertex must have an even number of paths connecting to it. This does not happen with graph 1 since vertex A and vertex D have an odd number of vertices (3 each). The odd vertex count makes it impossible to travel back to the starting point, while making sure to only use each edge one time only.

With graph 2, each vertex has exactly two edges attached to it. So an Euler circuit is possible here.

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

Problem 8)

The answer is choice B) 5

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

Work Shown:

abc base 2 = (a*2^2 + b*2^1 + c*2^0) base 10

101 base 2 = (1*2^2 + 0*2^1 + 1*2^0) base 10

101 base 2 = (1*4 + 0*2 + 1*1) base 10

101 base 2 = (4 + 0 + 1) base 10

101 base 2 = 5 base 10

Plz help me solve this question ASAP without using algebra, Thank u‼️

Let cost of 1 box of red pen = x

Let cost of 1 box of black pen = y

Gaga bought 5 red box and her sister 4 black box then total cost is given by

5x+4y

Given that total cost was $44

so equation will be 5x+4y=44...(i)

After exchange

Gaga= 4 red box + 1 Black box

Sister = 1 red box + 3 Black box

then cost for Gaga = 4x+1y

cost for sister = 1x+3y

Given that cost for both after exchange is same so we get

4x+1y = 1x+3y

or 4x-1x = 3y-1y

or 3x = 2y

or 3x/2=y ...(ii)

plug (ii) into (i)

5x+4y=44

5x+4(3x/2)=44

5x+12x/2=44

5x+6x=44

11x=44

x=4

Now plug value of x into (ii)

y=3x/2=3*4/2=12/2=6

Hence cost of 1 box of red pen = $4

And cost of 1 box of black pen = $6

---

If you want to get solution without solving both equations then just graph both equations and find the intersection point.

You will see that graph intersect at (4,6) which gives x=4, y=6

Find the circumference of the circle if the radius is 4 inches

Kitty [74]

Answer:

25.13

Step-by-step explanation:

C = d( $\pi$ )

d = r(2) in this case 4(2) = 8 = d

so 8( $\pi$ ) = C

C ≈ 25.13
