Pleas help -2(a)=a-10/4

Mathematics
1 answer:
8_murik_8 [283]3 years ago
7 0

Answer:

0.8333333333333333 (repeating)

Step-by-step explanation:

Well first the point of this problem is to get "a" by it self so.

-2a = a - 10/4

remove the fraction by multiplying 4 on both sides.

-8a = 4a - 10

now move 4a over to the other side to isolate the 10.

-12a = -10

now divide to get a by it self

-10/-12 = 0.8333333 (repeating)

**Remember a negative divided by a negative is a positive.

Answer:

The number printed in red color = 5

The number printed in silver color = 8

The number printed in blue color = 1

Step-by-step explanation:

P.S - The exact question -

Given - The diagram

To find - The number that represent Red, Silver and Blue color.

Proof -

Let the number printed in red color = r

Let the number printed in silver color = s

Let the number printed in blue color = b

Also,

Given that the equation is -

  b s r

  b s r

+ b s r

= r  r  r

Now,

We have to think of a number that if we add the last digit of the number gives the same last digit.

Bt inspection ,

the number would be 5

Because 5 + 5 + 5 = 15

Lat place of the equation is same

So,

The number printed on red color = 5

⇒r = 5

So, the equation becomes

  b s 5

  b s 5

+ b s 5

= 5  5  5

Now,

We have to think of a number whose last digit add up to 3  + 1 gives the last digit number 5 ( we add 1 because by adding 5 + 5 + 5 , we get 15 so we write the last digit 5 and 1 goes to the remainder and that remainder 1 will add up in the next number addition)(addition rule)

i.e.

s + s + s + 1 = number whose end digit is 5

By inspection,

The number would be 8

because 8 + 8 + 8 + 1 = 25

So,

we get

s = 8

So, the equation becomes

  b  8  5

  b  8  5

+ b  8  5

= 5  5  5

Now,

By same process , we will find the number of blue color

By inspection the number on blue color = 1

∴ we get

The number printed in red color = 5

The number printed in silver color = 8

The number printed in blue color = 1

and the equation is -

  1  8  5

  1  8  5

+ 1  8  5

= 5  5  5

Which answer is it? I just learned this today, so I'm confused.​
Naily [24]

Answer:

H. \sqrt{32} = 5.7 inches

Step-by-step explanation:

1) Because you multiply the length and the width to get the area, you just need to find the square root of the area.

When you look for the square root of 32, it is 5.6....

Round up and you get 5.7 inches which s the length of one side.

Therefore, H. is the correct answer.

What is the equation of the two points 3,5 and 5,0
DiKsa [7]

Answer:

The equation of the line is y = -5/2x + 25/2

Step-by-step explanation:

To find the equation of the line, we first need the slope. We can get that by using the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (5 - 0)/(3 - 5)

m = (5)/(-2)

m = 5/-2

m = -5/2

Now that we have the slope, we use the slope and the given point in point-slope form. Then we solve for y.

y - y1 = m(x - x1)

y - 0 = -5/2(x - 5)

y = -5/2x + 25/2
