Answer:

2a+7b-5

Step-by-step explanation:

7b + 7 + 5b – 5b + 2a – 12

2a+7b+5b-5b+7-12

2a+7b-5

Answer:

1:3

Step-by-step explanation:

3:12 is the amount of shaded circles to all circles, 8:2 is basically the same thing as 3:12 and 9:3 is the amount of shaded circles to the amount of non-shaded circles.  1:3 wouldn't work because it is not the right ratio.

Answer:

158/12-85/12 equals this in a decimal 6.083333333

and in a factor it is 73/12

Answer: 114 minutes

Step-by-step explanation:

From the question, we are informed that Han has Spent 75 minutes practicing the piano over the weekend while Priya practice the violin for 152% as much time as Han used in practicing the piano.

Therefore, the number of minutes used in practicing by Priya would be gotten by multiplying 152% by 75 minutes. This would be:

= 152% × 75 minutes.

= 152/100 × 75minutes

= 1.52 × 75 minutes

= 114 minutes

Answer: 1.23

Step-by-step explanation:

0.3*4.1=

Answer:

It is 1.23

Step-by-step explanation:

When multiplying decimals, multiply it as a whole number, and move the decimal to the left the amount of times it was in the problem.

i.e. .3 times 4.1

.3 has 1 number behind the decimal and 4.1 also has one number behind the answer. This means that you will move the decimal to the left twice in 123.0 to 1.23

Answer:

x = -55

Step-by-step explanation:

Subtract 7 on both sides first to get to this equation, x/5 = -11.  Since there is a fraction on the left side, you have to multiply 5 on both sides to get your x-value which is -55.

49, here's why...

a negative multiplied by a negative equals a positive, and if you're working with parentheses, and you don't see a sign, at all, then it means you have to multiply.

Answer:

39.5 [tex]ft^{2}[/tex]

Step-by-step explanation:

We need to take this shape by shape

Top triangle

a = b*h/2

a = 3*2/2

a = 6/2

a = 3

__________________________________________________________

Bottom triangle:

a = b*h/2

a = 3*3/2

a = 9/2

a = 4.5

__________________________________________________________

Rectangle:

a = b*h

a = 8*4

a = 32

__________________________________________________________

Now add them all up

3 + 4.5 + 32 = 39.5

The area of the shape is 39.5 [tex]ft^{2}[/tex]

Hope this helped!

Answer:

-29.988 or if you round up -30

Step-by-step explanation:

1) Convert fractions to decimals  

    3.6 x (-8.33) = -29.988

Answer:

I think its this but not sure

Answer:

look in explanation

Step-by-step explanation:

1) bisector means cutting an angle in half. the small lines between segment SM and MT mean they are congruent. this means MW is a bisector. Since both halves of ST are congruent, we know SM = 19. 19+19=38

2) same logic here, M bisects ST. set both halves of ST equal to each other and solve.

3x-6=x+8

2x+14

x=7

plug back in to find MT (7)+8=15. MT=SM so double 15 to get ST. ST=30

3) the bisector will be exactly halfway between the points.

4) find difference between x and y values, and divide by 2

2-2=0 0/2=0 x moves 0

13-1=12 12/2=6 y moves 6

so add 0 and 6 to 2,1 to get (2,7)

5) same process

6--6=12 12/2=6

6-0=6 6/2=3

add 6 and 3 to -6,0 to get (0,3)

6) find the change in x and y between the coordinate sets. (x: 1- -1=2) (y: 2-4=-2) take the opposite of those values and add them to M

(x:1-2=-1) (y:2+2=4)

(-1, 4) are the other coordinates for C

7) take the same steps

(x:3-1=2) (y:7-1=6)

use -2 and -6

(x:3-2=1) (y:7-6=1)

(1,1) are other coordinates for C

8) use distance formula

sqrt (x1-x2)^2 + (y1-y2)^2

sqrt(1--1)^2 +(2-4)^2

sqrt (2)^2 +(-2)^2

sqrt 4+4

sqrt 8

9) same process

sqrt (-1-3)^2+(-5--8)^2

sqrt (-4)^2 +(3)^2

sqrt 16+9

sqrt 25

Step-by-step explanation:

1/2 (3/4x + 10) - 2 (x + 1)

3/8x + 5 - 2x - 2

Combine like terms

3/8x - 2x + 5 - 2

-1 5/8 + 3

HAVE A NICEE DAY

Answer: If you add all of these numbers of gumballs up you get 50. Since there is 50 gumballs,and 100 percent of that amount has to be filled,then you must make each gumball worth 2 percent. (12x2)+(22x2)+(12x2)+(4x2)=100

Green percent of getting=24 percent

Purple percent of getting=24 percent

Blue percent of getting=8 percent

White percent of getting=44 percent

The percent of getting a White gum is 44 percent.
