please show work

Answers

Answer 1

(-1/4) x (-3/7)

= (-1 x -3)/4 x 7

= 3/28

3/28 is the answer.

Hope it helps:)

Please mark me as the Brainliest.

Answer 2
Answer: 3/28

Step by Step Explanation:
To solve this equation, we do NOT need the same denominator.
And since both fractions are negative, we know the answer is going to be positive.
So we just multiply normally.

-1/4 • -3/7

We cannot cross cancel anything, so we just multiply across.

-1 • -3 = 3
-4 • -7 = 28

So our answer is 3/28.

Hope this helps! :3

Answers

Answer:

4 8/12

Step-by-step explanation:

7/4 = 1 3/4

2/4 = 1/2

4/12 = 1/3

1/4 = 1/4

20/12 = 1 2/3

2/4 = 1/2

multiply the numerator and the denominator by 4 because 12 is a factor of 4 and 3

do that to all of the fractions (except the one that already has 12 as the denominator)

the add all of them together because they all have the same denominator

In this question, the algebra equation is a[3(5b - c)]. Since a = 1.6, b = 2, and c = 5, we would replace the equation into 1.6[3((5)(2) - 5)).

With this equation, the answer will be 24
Answer: 24

Step by Step Explanation:
Since we know what our variables are, we will plug in 1.6 for a, 2 for b, and 5 for c.

1.6[3(5(2) - 5)]

Now we solve and work from the inside out!

1.6[3(10 - 5)]

1.6[3(5)]

1.6 • 15

= 24

So our answer is 24!

Answers

Answer:

C.

Step-by-step explanation:

The answer is C, as as any value of m will make the equation true.

Such as if we used 2 as a substite value for m.

[tex]-6(2)-6+8(2)=-5+2(2)-1[/tex]

Lets simplify both equations:

[tex]-6(2)-6+8(2)=-2[/tex]

[tex]-5+2(2)-1=-2[/tex]

Now, if you want, you can also use any other value for m, but that is basically how I got C. If they equations didn't have the same answer, then it would be B. If it only worked for 2 numbers, then it would be A. Now, I tried this equation again with -3=m, but I still ended up with the same answers. So it wouldn't have been D.

I believe the answer is c

find x and y if p || q and m3=(4x+6y),m5=86,and m6=(5x+6y)

Answers

Answer:

(8, 9)

Step-by-step explanation:

3 and 5 are vertical angles and are equal as per definition of vertical angles

4x + 6y = 86

5 and 6 are supplementary angles and sum up to 180 as per definition of supplementary angles

5x + 6y + 86 = 180 ⇒ 5x + 6y = 94

Comparing the two equations

6y = 86 - 4x and 6y = 94 - 5x86 - 4x = 94 - 5x5x - 4x = 94 - 86x = 8

Finding y

6y = 86 - 8*46y = 86 - 326y = 54y = 9
