Answer:
Step-by-step explanation:First add then multiply then call it mathematics money on ya answer is 2xy€hj67
⓵ You need to solve the left side first in order to isolate the × and find it’s value :
-7× + 6 = 27
-6 -6
↓
-7× = 21
÷-7 ÷-7
↓
× = -3
If you find it too difficult to divide a number by a negative, just divide 21 by 7 and always remember that when dividing, when the signs are different the answer is negative. So knowing that you could just divide 21 by 7, which is 3, and add a negative sign in front!
I hope this helped, if there’s anything let me know! ☻

When multiplying decimals, what you do with the decimal point is; C: line up the decimal points
<h3>How to Multiply Decimals?</h3>
A common way to multiply decimals is to treat them as whole numbers, and then position the decimal point in the product. The number of digits after the decimal points in the factors determines where the decimal point is placed in the answer. For example, 0.3 x 0.8 = 0.24.
Now, when multiplying decimals, the most important step is to line up the decimal points. Line up the decimal points so that similar place values are lined up. In other words, the tens place in both numbers should be lined up, the ones place in both numbers should be lined up as well and son.
Thus, option C is the correct answer.
