Answer:
B
Step-by-step explanation:
So we have the expression:
Since 5 goes into both 15 and 50, we can factor out a 5. First, rewrite the numbers as:
Factor out the 5:
So, our answer is B
And we're done!
98 divided by 2 equals 49
55 divided by 5 equals 11
Answer:
The only answer that would work would be D) | 4.8 - ( -2.3) |
Step-by-step explanation:
This is because the distance is the absolute value of the difference of the two numbers. B and C would also work, but the 2.3 is not negative. A does not work because it is addition.
defective : working = 1/15 ( x20 ) 20/300
so the answer is 20 light bulbs
Answer:
x = 67; y = 40
Step-by-step explanation:
You are correct with y. Angles y + 23 and 63 are vertical, so they are congruent. That gives you y + 23 = 63, which gives y = 40.
To find x, look at angles 2x - 17 and 63.
They are adjacent angles whose outside rays lie on a line. Angles like these are called a linear pair, and they are supplementary. That means their measures add up to 180 deg.
2x - 17 + 63 = 180
2x + 46 = 180
2x = 134
x = 67
