Step-by-step explanation:
First break it down
42= 40 & 2
27= 20 & 7
- Then times 40 & 20 to get 800
- 20 x 2 to get 40
- 40 x 7 to get 280
- 7 x 2 to get 14
Now add them all together.
800 40 1080
+280 +14 + 54
---------- ------- ---------
1080 + 54 = 1134
.5 because first you add 1 on each side, that gets rid of the 1 on the left. then divide by 4
Answer:

Step-by-step explanation:
Given the system of equations:

You can pply Substitution method:
First you must solve for "y" from the first equation:

Therefore, the second and final step to solve the system of equations is to substitute the value of "y" into the second equation and solve for "x":

Answer:
At least one of the integer must be equal to zero to obtain the product zero
Step-by-step explanation:
we know that
When multiplying integers
, if one or both of the integers is 0, then the product is 0.
The multiplication property states that the product of any number and zero is zero.
so
a*(0)=0
therefore
At least one of the integer must be equal to zero to obtain the product zero
therefore
Answer:
He actually has 25 paints.
Step-by-step explanation:
This is because you take 18x100(100 is the total % under 72 because 72 is out of 100) that equals 1800. then, you take 1800 and divide it by 72. That is because 72 is the actual number that we already have. You would get 25 after dividing. hope this helps:)
