Solve for these letters<br> X<br> Y<br> Z
tester [92]
Z = 140
X = 40
Y = 40
Explanation:
Z and the angle given (140 degrees) are vertical angles, and are therefore congruent
We know that x and y are vertical angles, so they are also congruent to each other
You know that together, the angles have to add up to 360
140 + 140 + x + y = 360
Another way of putting it:
360-280 = 80
Now, we have to divide by two since we need to find x AND y
80/2 = 40
Therefore, your answers for x and y are 40
To double check, you can add up the angles and see if they equal 360
140 + 140 + 40 + 40
280 + 80 = 360

1/6 + 3/8 <br> A. 4/6<br> B. 4/8 <br> C. 4/14<br> D. 13/24
Naddika [18.5K]

Here is you're answer:

In order to get you're answer you need to find the common denominator then add.

  • \frac{1}{6} + \frac{3}{8}
  • Find the common denominator:
  • CD = 48
  • = \frac{26}{48}
  • Simplify:
  • \frac{26}{48} \div 2 = \frac{13}{24}
  • = \frac{13}{24}

Therefore you're answer is option D "13/24."

Hope this helps!

I need help and i would appreciate it and can you explain (That's if you can explain)
Finger [1]

Answer:

x=-2

y=-3

Step-by-step explanation:

-9x+4y = 6

9x+5y = -33

We will add these together to eliminate x

-9x+4y = 6

9x+5y = -33

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

0x +9y =- 27

9y = -27

Divide by 9

9y/9 = -27/9

y =-3

We still need to find x

9x +5y = -33

9x +5(-3) = -33

9x-15 = -33

Add 15 from each side

9x+15-15 =-33+15

9x=-18

Divide by 9

9x/9 = -18/9

x = -2

$750,000 is what percent of $3,000,000?<br> Please help
velikii [3]

Answer:

25

Step-by-step explanation:

Solution for 750000 is what percent of 3000000:

750000:3000000*100 =

(750000*100):3000000 =

75000000:3000000 = 25

Now we have: 750000 is what percent of 3000000 = 25

Question: 750000 is what percent of 3000000?

Percentage solution with steps:

Step 1: We make the assumption that 3000000 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x​.

Step 3: From step 1, it follows that $100\%=3000000$100%=3000000​.

Step 4: In the same vein, $x\%=750000$x%=750000​.

Step 5: This gives us a pair of simple equations:

$100\%=3000000(1)$100%=3000000(1)​.

$x\%=750000(2)$x%=750000(2)​.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{3000000}{750000}$

100%

x%​=

3000000

750000​​

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{750000}{3000000}$

x%

100%​=

750000

3000000​​

$\Rightarrow x=25\%$⇒x=25%​
