what is -2 x 3 i do not understand this and this is my last problem
Answer:
-6
Step-by-step explanation:
if they were both positive numbers, it would be 6. But when you multiply a negative by a positive, the answer is negative.
Answer:
-6
Step-by-step explanation:
When you multiply a positive number by another positive number, you will always get a positive number as your answer. Same thing for negative. If you multiply a negative by a negative, you will always get a positive. However, when you multiply a negative by a positive, you will always get a negative number.
Since you know this, you can multiply 2 by 3, which is 6. Because 2 is negative and 3 is positive, you know that the answer must be negative. Therefore, you add the negative symbol to 6, giving you -6.
I hope this isn't too confusing. Please let me know if you have any more questions. Good luck!

Answer:
156.6 meters squared
Step-by-step explanation:
There are 3 triangles for the sides. The area for a triangle is one half base times height. So we are doing one half of 9 times 9. This is 40.5. Since there are 3 of them we can just multiply 40.5 times 3 to get 121.5. And now to solve for the base triangle, it is one half of 9 times 7.8. We get 35.1. Now add together 121.5 and 35.1. We get 156.6. Now since this is surface area it is meters squared.

Jessica went to dinner and her bill was $15.60. If she wants to leave a 15% tip, how much is the tip? How much did she spend total after the tip?
Answer:
A) $2.34
B) $17.94
Step-by-step explanation:
First in order to find the tip you need to set up a proportion:
15/100 = x/15.6
Step 1: Cross-multiply.
15/100 = x/15.6
(15)*(15.6) = x*(100)
234 = 100x
Step 2: Flip the equation.
100x=234
Step 3: Divide both sides by 100.
100x/100 = 234/100
x = 117/50 (2.34)
The tip is $2.34
Now to find the total, add the tip to the bill.
15.6+2.34
= 17.94
The total bill was $17.94

Total number of cards = number of cards worth more than 100 divided by the rate of those cards among total cards = 12/40% = 30
SOLVE FOR X TO THE NEAREST TENTH
Answer:
x = 8.8
Step-by-step explanation:
First, you have to solve the side length for the smaller triangle.
[tex]c= \sqrt{ a^{2} +b^{2} }\\c= \sqrt{5^{2}+4^{2} } \\\\c=\sqrt{25+16} \\c=\sqrt{41} \\c= 6.4\\[/tex]
Now for the bigger square.
[tex]c= \sqrt{ a^{2} +b^{2} \\} \\c = \sqrt{6.4^{2} +6^{2} } \\c= \sqrt{40.96+36} \\c= \sqrt{ 76.96}\\c= 8.77\\[/tex]
Rounded to the nearest tenth = 8.8
