Answer:
-2a
Step-by-step explanation:
a - 6a becomes -5a, add 3a becomes -2a. The expression equivalent to a - 6a + 3a is -2a.
Answer:
54 degrees and 90 degrees
Step-by-step explanation:
If you add up all the angles in a triangle it will equal 180 degrees. So first, subtract 36 from 180
180 - 36 = 144
If the other two angles have a ratio of 3 to 5 then you need to divide 144 by 8 because 3 + 5 = 8
144/8 = 18
Then multiply 18 by 3 and 5. This will give us the measurement of the other two angles.
18 x 3 = 54
18 x 5 = 90
90 + 54 + 36 = 180
Answer:
Step-by-step explanation:
Creating identical expressions involves changing quantities in a way that preserves the end values specified in the equation.
For instance, if Lei sold 4 carnations:
In the second equation listed, the expression (8 + 0.25c) was multiplied by 4, then by 0.25, for a total multiplicand of 1.
You can make a third equation through the same method. I'll multiply (8 + 0.25c) by 2, and then multiply that expression by 0.5 to keep the multiplicand unchanged:
If Lei sold 4 carnations:
0.5 * (16 + 2) = 9
This equation represents the same quantities as the other equations.
86x71 equals the amount of the people in the chapters pls
I'm not sure if you were supposed to add two numbers together to get five? If that's the case the answer would be 5/3. If it's not i'm sorry, I tried.
