I'm assuming you meant to say a^3. If so, then
a^3 = a*a*a
a^3 = 5*5*5
a^3 = 125
Answer:690 580 470 360 250 140
Step-by-step explanation:
These digits are all numbers that the hundreds digit is three less than the tens digit, the ones digit is also zero
Answer:
160 2p coins
Step-by-step explanation:
3/8 x 640 = 240 = 1p coins
240 = 5p coins
240 + 240 = 480
640 - 480 = 160
I hope you want to simplify this expression.
To simplify the given expression we can use the order of operation.
So, first step is to operate multiplication. Therefore,
400 x 34 = 13600
Hence,
400x34+23444444444-23444444444
= 13600 +23444444444-23444444444
= 13600 + 0 Since +23444444444-23444444444 = 0
= 13600.
So, the simplified value of the given expression is 13600.
Hope this helps you!.
Sorry I am a little late...
a = -2
b = -9
Here is how to solve the problem.
First thing I did was multiply the first equation by -2 so that we can eliminate the the b. After you multiply it by -2, your new equation is -16a + 8b = -40.
You leave the second equation alone and all you do is combine like terms. So -16a+5a is -11. And you eliminate the b. Then you're going to do -40+62 which is 22. So it's -11a=22 and then you have to solve for a. What I did was I multiplied the whole thing by minus to turn the a positive. So then it's 11a=-22. Pretty easy, the final step is to simplify. -22/11 is -2. ;D
So there you have your first answer.
a = -2
Now we're going to use the first answer to help us find b.
For the second equation, all you're going to do is plug in that a.
5 (-2)-8b=62
-10 - 8b = 62
Now we move the -10 to the other side...
-8b = 62 + 10
-8b = 72
Multiply the whole thing by negative once again to turn the b positive.
Now we have 8b = -72
The final step is to simplify. -72/11 = -9
b = -9
Hope this makes sense! Also I had the same question on my test and I got it right. :)
