Answer: 6.

Explanation:

The picture is blur.

I got that answer and will explain you the solution assuming the expression is:

8 + 24 ÷ (2 x 6) - 4.

Before adding 8 to 24 ÷ (2 x 6) you have to solve 24 ÷ (2 x 6).

Start by solving the parenthesis: (2 X 6) = 12

Now perform the division: 24 ÷ 12 = 2

Now you can add and subtract: 8 + 2 - 4 = 10 - 4 = 6.

You can perform these operations directly in an ordered way:

8 + 24÷(2x6) - 4 = 8 + 24÷12 - 4 = 8 + 2 - 4 = 6

Step-by-step explanation:

5x+52=9x+20

subtract 5x on both sides

subtract 20 on both sides

32=4x

divide by 4 on both sides

x=8

plug in x to the equations for A, D, and C

A and D are 92°

C is 56°

B and C will add up to 90, so

90-56=34°

13y-6=34

add 6 on both sides

13y=40

divide by 13

y=40/13 (I don't wanna calculate that)

The fractions of -42/-45 and 14/15 are equivalent

FromTheMoon [43]

Yes, that is true, you have to simplify -42/-45 to be able to see if they are equivalant.
$\frac{ - 42}{ - 45} = \frac{14}{15}$

the dog needs a 1/3 of a cup of dog food each day. the bag holds 5 cups of dog food how many days will it last ?

Answer:

15 days

Step-by-step explanation:

You have 5 cups of food, and you give him 1/3 a day.

So, 5 divided by 1/3, which would get you 15 days. Or you could cross-multiply, meaning you multiply across, but in this case I just made them line up so you can see how to do it. $(food)/(cupsperday) = 5/\frac{1}{3} \\OR\\\frac{(food)}{1}*(cupsperday) = \frac{5}{1} *\frac{3}{1}$
