The answer is 2/5. 2*2=4 and 2*5= 10, 2*3=6 and 3*5=15
First one (on the left) is 2) associative property because we are regrouping terms or re-associating them based on the parenthesis. Think of the parenthesis like a tent or a house that separates off the stuff outside. First 27 and 36 are grouped, then we move the parenthesis so that 52 and 27 are grouped now.
Second one (on the right) is 1) commutative. The commutative multiplication property says we can multiply two numbers in any order. For example, 4*9 = 36 and 9*4 = 36. The 4 and 9 swap places. In this problem, the 3 and 4x swap places. The use of parenthesis isn't necessary, though it is sometimes used to imply multiplication.
You would use the equation x + x + 65 + 25 = 180. The equate should be equal to 180 since a triangle is 180 degrees. Then use the equation and solve
2x + 90 = 180
2x = 90
x = 45
Hope you understand!
Answer:
2
Step-by-step explanation:
13 × 4 = 52
52 ÷ 26 = 2
13 × 4 = 2 × 26
<u>n</u><u> </u><u>=</u><u> </u><u>2</u>
The answer is 2 hours and 55 minutes. This is because 90 + 85 = 175.
2 hours is equal to 120 minutes thus needing 55 minutes to equal the 175 minutes total.
