Answer:
Step-by-step explanation:
<u>Two-digit numbers are:</u>
<u>Sum of them is:</u>
- 10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 528
- 22a + 22b + 22c = 528
- a + b + c = 528/22
- a + b + c = 24
The only option of three different digits with the sum of 24 is 7, 8 and 9
Answer:
The answer is y=20
Step-by-step explanation:
If you take a look at the attached picture you will notice that angles B and C are congruent, so that means they both are 25 degrees.
Next, add angles B and C together to get 50.
Then you take that 50 and add it to 70 in angle A's equation, and you will get 120.
Next, plug 120 into angle A's equation where the 70 was and you will have the equation 3y+120=180. (180 is there because that is what all the interior angles equal together.)
Next, slove the equation.
- 3y+120 = 180
- -120 -120
- 3y = 60
- /3 /3
- y = 20
And theres your answer, I hope I helped. Put any questions in the comments.
The answer would be B. 2 times x would equal an even number, and an even number plus 3 will be an odd number.
You answer this by isolating the variable. This means you work on the side where the variable is and do reverse operations to undo what was done in reverse "pemdas" order.
Start by translating and writing an equation:
Let x be the number
so:
12-1/4 x = 22
now subtract 12 from both sides. (because 12-12=0)
12-12-1/4 x =22-12 (now simplify)
-1/4 x = 10
next you want 1 x, not -1/4 x.... so to get to 1 you multiply both sides by the reciprocal of -1/4 which is -4/1
-1/4 * -4/1 x = 10 * -4/1 (multiply and simplify)
x = -40
