1/5 of 3 ..
=> 1/5 * 3 is same as 3 * 1/5 ..
=> 1/5*3 = 3/5 and 3* 1/5 also = 3/5 ...
here t<span>he </span>commutative property of multiplication is used ... which tells us that it doesn't matter in what order you multiply<span> numbers. The formula for this </span>property <span>is a * b = b * a. .... so if we know these properties it will be easy to figure out the answer ...
hope it helps !!!!</span>
Answer:
x = 54
Step-by-step explanation:
All triangle angles add up to 180 so:
x + 36 + 90 = 180
x + 126 = 180
x = 180 - 126
x = 54
10.) DC
community property
11.) 13+x
community property
12.) 8x-12
distributive property
13.) (2+a)+b
14.) 4(2x+1)= 4+8x
For question 14 you can do 4×2=8x. Then do 4×1=4. It is equal. Just do distributive property for number 14 for 4(2x+1)
