Hi so you start with PEMDAS wich means parenthesis exponents multiply divide add and subtract so that's the order.
so we start with the order so its parenthesis so 10 minus 8 is to and are the question now looks like this: 3 + 4 2
Now when are two numbers together and they don't have a sign we multiplied together.
it looks like 3+4x2
Now we multiply because we follow the rule.
now it looks like this: 3+8
Now 3 plus 8 is 11 so your answer is 11
Hope I had helped.
The value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286
Rational numbers are numbers written as the ratio of two integers. For example, the fraction 2/7 given is a rational number.
Expressing 2/7 as a decimal number will give;
2/7 = 0.2857142... (It gave repeated decimal values)
Truncating the repeating decimal to the nearest thousandth means writing the decimal to 3 decimal places
0.2857142 = 0.286 (to the nearest thousandth)
Hence the value of 2/7 expressed as a truncated decimal to the nearest thousandth is 0.286

Hey there!
2/3 = a/30
First: you have to CROSS MULTIPLY the given numbers
2(30) = 3(a)
2(30) = 60
3(a) = 3a
New EQUATION: 3a = 60
Second: DIVIDE 3 to BOTH SIDES
3a/3 = 60/3
CANCEL out: 3/3 because that gives you 1
KEEP: 60/3 because that helps you solve for your a-value
60/3 = a
60/3 = 20
Therefore, your answer is: a = 20
Good luck on your assignment and enjoy your day!
