A pound of rice crackers ... $2.88
1/4 pound of crackers ... $x = ?
If you would like to know how much did Matthew pay for the crackers, you can calculate this using the following steps:
1 * x = 1/4 * 2.88
x = 1/4 * 2.88
x = $0.72
Result: Matthew paid $0.72 for 1/4 pound of crackers.
Answer:
a=2 , b= (-1)
Step-by-step explanation:
8a-4b=20/×(-2)
5a-8b=62
-16a+8b= -40
5a-8b=62
now -8+8=0 right? so the only parameter that we have is a.
-16a+5a= -40+62
11a = 22/(÷11)
a=2
in order to find b, we will replace a with its value in one of the original equations (it doesn't matter which one you will choose).For instance, I chose the first one.
8×2-4b=20
-4b=20-16
-4b=4/÷(-4)
b= -1
Answer:
9,400
Step-by-step explanation:
12,846 - 3,467 = 9,379
The hundreds digit is 3.
So, you look to the left of the digit and if it is 5 for more you add a number to the 3 and make the rest of the digits 0s. But if it below 5, then you leave the 3 alone and make the rest of the digit going to the right 0s.
Then, your answer is (9,400)
Hope this helps ; )
