Answer:

-48

Step-by-step explanation:

A couple things to note:

In math, product means multiply. So the question wants you to multiply -12 and 4.
When you multiply two numbers, and one of them is negative, the entire problem is negative. If two of them are negative, the answer is positive. Basically, an odd number of negatives means the answer is negative, and an even number of negatives means the problem is positive.

Using both of those things, we can now just multiply 12 and 4 like normal, and then add the negative to get -48 :)

$280 divided by $35 is 8, so it would take 8 months for Manuel to reach his goal.

Dante and Mia have a total of 350 pennies in their piggy banks, altogether. After Dante lost half of his pennies and Mia lost on

tatuchka [14]

Answer:

150 pennies were lost altogether

Step-by-step explanation:

Let the initial number of pennies owned by Dante be x pennies

Let the initial number of pennies owned by Mia be y pennies

Mathematically ;

x + y = 350 •••••••(i)

So after losing half, dante will have x/2 pennies left.

Mia lost 1/3 so she will have 2/3y left

So after all the losses, they both had equal amount of pennies

This means that;

x/2 = 2y/3

Cross multiply;

3x = 4y •••••••(ii)

Let’s solve both equations simultaneously;

From i , x = 350-y

Substitute this into equation ii

3(350-y) = 4y

1050-3y = 4y

7y = 1050

y = 1050/7

y = 150

since x = 350-y

x = 350-150 = 200

Now Dante loss x/2 = 200/2 = 100

Mia lost 1/3y = 1/3 * 150 = 50

Total pennies lost = 100 + 50 = 150
