Answer:
120 degrees.
Step-by-step explanation:
All the angles in a triangle add up to 180. You have two of the angles given:
50 degrees and 70 degrees
To find the third angle of the triangle (BAC), use the expression:
180 - (50 + 70)
180 - 120
60
So, the third angle in the triangle is 60 degrees. Looking at angle DAB, you can see that it forms a straight line with angle BAC. A straight line is 180 degrees. Since we know BAC is 60, and BAC + DAB = 180, by doing 180 - 60, you can see that angle DAB is 120 degrees.
Hi!
To solve this problem you can set up a proportion (I like doing it this way) or you can just do:
First deal:
(24/3)*5 = 40 dollars
Second deal:
(24/4)*6 = 36 dollars
Finding money saved:
40-36 =4
They will save 4 dollars buying the second 4 for 6 dollars deal!

7(36-2c+4)
=252 - 14c + 28
=310 - 14c
Answer:
Step-by-step explanation:
2t + 3t = 6t is false. The correct answer is 5t.
y + y + y = y(1 + 1 + 1) is true. Correct answer is 3y.
3(2 + x) = 6 + 3x is true. This is an application of the distributive rule for mult.
2a + 2b = 4ab is false. a and b are separate variables with no given relationship to each other. Correct answer would be 2(a+b).
x + 3 = 4x is false. x + 3x = 4x would be true.
