Answer:
x=0
Step-by-step explanation:
<u>Key skills needed: Proportions, Cross multiplication, One variable Equations, Multiplication</u>
1) Since this is a proportion, we need to cross multiply. A proportion is just 2 fractions equal to each other in this format.
---> Cross multiplication is when you multiply the first fraction's numerator by the second fraction's denominator, and you multiply the first fraction's denominator by the second fraction's numerator.
---> You set these products equal to each other.
2) So if we cross multiply it would be: 3(3x+5) = 5(3-2x)
---> If you multiply everything out, it would be --> 9x + 15 = 15 - 10x
3) Move the x terms to one side and the numbers to the other side
---> 9x + 10x = 15-15
4) Combine like terms (9x+ 10x= 19x) (15-15=0) 19x = 0
5) Divide by 19 and x=0.

Answer:
dale is not correct
the correct angle is 30 degrees
Step-by-step explanation:
A cake is shaped like a circle
the total sum of angles in a circle is 360 degrees
If Dale and 2 friends share one fourth of a cake, the total angles they share = (1/4) X 360 = 90 degrees
If the 3 friends share the cake equally, the angles each get = (1/3) x 90 = 30 degrees
the correct angle is 30 degrees and not 45 degrees. Thus, Dale is wrong
