Answer:
14 square roots of 2 is correct
Step-by-step explanation:
Answer:
x = 8 and y = 10
Step-by-step explanation:
The given equations are :
2x -y = 6 ....(1)
-9x + 3y = -42 ....(2)
Multiply eqation (1) by 3.
6x - 3y = 18 .....(3)
Adding equation (2) and (3).
-9x + 3y + 6x - 3y = -42 +18
-3x = -24
x = 8
Put the value of x in equation (1).
2(8) -y = 6
16 - 6 = y
y = 10
Hence, the values of x and y are 8 and 10 respectively.
Answer:
3/4 / 1/6
keep the first fraction the same
3/4
flip the second fraction
6/1
change the division to a multiplication it should then read
3/4 X 6/1
now multiply the fractions
3 X 6 = 18
4 X 1 = 4
18/4 this can then be turned into a mixed number.
there are four 4's in 18 with two left over. so it becomes
4 2/4 and simplified 4 1/2.
Basically when reading the value of a digit we start from the right.
Digits from the right to the left are named as follows:
units......>no zeros/digits after them
tens......> 1 zero/digit after the digit
hundreds.......> 2 zeros/digits after the digit
thousands......> 3 zeros/digits after the digit
ten thousands.......> 4 zeros/digits after the digit
hundred thousands.........> 5 zeros/digits after the digit
million........> 6 zeros/digits after the digit
Applying this on the above mentioned numbers, we will find that the 3 represents the hundreds (300) in 6300 while it represent the tens (30) in 530.
The question is to find the difference between the two, which means we will subtract them:
difference = 300 - 30 = 270
<span>The value 3 in 6300 is 270 times the value of 3 in 530
