In order to solve this problem, we transform the statements into
algebraic expressions. First, we assign the variables.
Let:
x = Gina’s number
y = Sara’s number
For the first equation, we show that Gina’s number is greater
than Sara’s number by 2. For the second equation, we show that the sum of both
numbers is 68.
<span>(1)
</span>x – y = 2
<span>(2)
</span>x + y = 68
<span>We
add the two expressions, which result in the expression: 2x = 70. Then we
divide 70 by 2 to get the value of x. We then have x = 35. Using the second
equation, we solve for y = 68-35. This gives y = 33. To summarize, Gina’s
number is 35 while Sara’s number is 33.</span>
Answer:
no
Step-by-step explanation:
3.6 + 3.6 is not 9 & 2.84 + 2.84 is not 7.1
This question is basically asking you what number was this originally until we timesed it by 100. For the first column take away two zeros or for answers like 560 and 4830 imagine there is a decimal point at the end and move it two spaces forward so it would now be 5.6 and 48.3
For the second column add two zeros at the end instead.
For the questions at the bottom basically for all the questions except the bottom one how many numbers follow the first number.
For example.
96,629 = 1
100
Because three numbers follow the first 6.
Hope this makes sense because I don’t know if it does.
D) 180 because there are 180 possible combinations for the marbles to be picked out
Answer: C) Cannot be done
Taking the square root of a negative number is not possible unless you involve complex numbers. If your teacher has not introduced that topic yet, then you just simply say "cannot be done" or something along those lines.
