Answer:
33
Step-by-step explanation:
If m = Mother's age and d = daughter's age, we can make the following equations
m = 3d
m + d = 44
Now, using substitution, we can substitute m for 3d in the second equation:
3d + d = 44, 4d = 44, d = 11
Then, we can plug d into the first equation: m = 3(11) = 33
180- 113 = 67
180- 67= 113
<5= 67
<2=113

When multiplying several factors together, an even number of negative signs will result in a positive answer.
↠ Because when you multiply two negative signs together, the negative signs turn into a positive sign, giving you a positive answer.
↠ If you have an even number of negative signs to multiply, then all your negative signs will be turned into positive signs, giving you a positive answer!
⓶
When multiplying several factors together, an odd number of negative signs will result in a negative answer.
↠ Because when you multiply a negative sign by a positive sign, the negative sign always wins, giving you a negative answer.
↠ If you har an odd number of negative signs to multiply, this means that once you are done multiplying all of the negative signs together except for the last one, you will be multiplying a positive sign with a negative sign.
↠ Here’s another way to see it : if you have 5 negative signs to multiply together, you will start by multiplying the first 2, which will give you a positive result. Then you will multiply the third and the fourth negative signs together, which will also give you a positive result. By that time, you will have two positive signs and one negative sign left, which means you will have no choice but to multiply a positive sign by the last negative sign, resulting in a negative answer!

Inadequate problem statement. I'm assuming you meant "find the number of bananas lost in a 20% decrease from 160 bananas." That would be 0.20(160), or 32 bananas lost, with 128 bananas remaining. Please include all details when you share a problem statement.
Answer:
Pounds of grapes: 8; total cost: $5.52
Step-by-step explanation:
- Find the proportional relationship for 1. 1:0.69
- You can eliminate 3 off the top
- Try 11 first since it is the largest and the table is increasing in pounds. 11:7.59 (incorrect)
- Try 8. 8:5.52 (correct)
