Answer:
Subtract $4.60 from 0.05
Step-by-step explanation:
Answer: The other number is 100.
Step-by-step explanation:
The least common multiple (LCM) of two numbers is 200
The greatest common denominator (GCD) is 4.
One of the numbers is 8, which is the other number?
Ok:
First, we can write 8 as: 2*2*2 = 2^3 = 2*4
Now, the minimal common denominator can be any number that is written in the form
x = 4*a*b..
where a, b etc are prime numbers.
We also know that
LCD(a,b) = a*b/GCD(a,b)
LCD(8,x) = 8*x/GCD(8, x)
200 = 8*x/4
x = 200*4/8 = 100
the other number is 100.
Answer:
(1,-1)
Step-by-step explanation:
y = -1
5x+7y = -2
Substitute the first equation into the second
5x + 7(-1) =-2
5x -7 = -2
Add 7 to each side
5x-7+7 = -2+7
5x= 5
Divide by 5
5x/5 = 5/5
x =1
(1,-1)
<span>The answer is that x = 21/9.
Start with the original: 4(2x - 1) - 7 = 4 - x + 6
Now distribute the 4:</span> <span> 8x - 4 - 7 = 4 - x + 6.
Now combine the like terms. 8x - 11 = -x + 10.
Now add x to both sides. 9x - 11 = 10.
Now add 11 to both sides. 9x = 21.
And divide by 9 on both side. x = 21/9. </span>
Answer:
Step-by-step explanation:
If you subtract the extra 12 quarters from the total, you have $4.55 that can be made up of groups of 1 quarter and 1 dime. Since those groups are worth $0.35, there are $4.55/$0.35 = 13 of them.
There are 13 dimes and 13+12 = 25 quarters in the purse.
