Answer:
Noah is correct
Step-by-step explanation:
When we multiply a whole number, (without decimal notation) by 10 we can arrive at the correct answer by adding 0 to the right end of the number. However, it is not the general rule as the above method only applies to whole numbers because we have.
10 × 5 = 50
However,
10 × 5.0 ≠ 5.00
And
10 × 0.05 ≠ 0.050
The general rule is when multiplying a number by 10 it simply means shifting the decimal place one position to the left. The result of which is for whole numbers, when we shift the decimal place one place to the left, we add a zero to the right end of the number as follows;
10 × 30 = 300
Also when we multiply a decimal (fraction) by 10 we shift the place of decimal (decimal place) one decimal place to the right as follows;
10 × 0.003 = 0.03
Therefore, simply adding 0 to the right end of a number (including numbers with decimal fraction) when the number is multiplied by 10 to get the correct result is not always true.
Answer:
2x + 3
Step-by-step explanation:
product means to multiply, hence
the product of 2 and a number x = 2 × x = 2x
3 more than means add on 3, thus
expression is 2x + 3
I hope this helps you
QR=WS=2.93
RS=QW =2.04
QS=XR =2.28
RS=XQ=2.04
SY=QR =2.93
RY=QS =2.28
XY=XR+RY=2.28+2.28=4.56
XW=XQ+QW=2.04+2.04=4.08
WY=WS+SY=2.93+2.93=5.86
Perimeter of XYW=XW+WY+XY
Perimeter of XYW=4.08+5.86+4.56
Perimeter of XYW =14.5
2 - x. because if you replace the x with any number you will get the same answer except for in 2-x. Ex
2 - 4 = -2
4 - 2 = 2
-2 + 4 = 2
4 + (-2) = 2
Step-by-step explanation:
(-2/3)/(-1/2) ➡ (-2/3)×-2 = 4/3
