Answer:
Step-by-step explanation:
Distributive property: a(b +c) =(a*b) + a*c
12(7n - 4) =12*7n - 12*4
= 84n - 48
Answer:
24
Step-by-step explanation:
36:45 = x:30
36 x 30 = 1080
1080/45 = 24
To add or subtract fractions, you must find the common denominator. To do this, you must find a factor that is common between the two denominators, in this case its 3 because 4x3=12. So multiple 1/4 by 3 and you should get 3/12. Then simply add and subtract the numerators, so +- is essentially just subtraction so to simplify the equation, it would be 3/12-3/12-5/12. So 3/12-3/12= 0, 0-5/12= -5/12. So the answer is -5/12.
Hope this helps!
Answer:
116 degrees
Explanation:
If we divide the triangle from the vertex of the triangle, the vertex angle of each triangle would lie on a straight line in the triangle. Angle on a straight line is 180 degrees.
If the vertex angle of one triangle is 64 degrees then the vertex angle x of the other triangle is 180 degrees - 64 degrees = 116 degrees.
A pint contains 2 cups. 2 pints would produce 4 cups, not 5. I do love rhubarb!
