Step-by-step explanation:
Let the number is x. Its reciprocal will be 1/x. According to given condition, we get :
It is a quadratic equation. The values of x are :
The smaller number is 4/5 and the larger number is 5/4.
It is an integer and a rational number
Answer:
1000 less 35% == 650
so 250 given to charity
total cost making the pins was 1000x 1.10 = 1100
so you need to find 60 percent of 650 =390
and 40 percent of 650 = 260
so then you need to find the cost 390 x 3 pounds each so × this and gives you 1170 cost sold for intotal
Then you have 260 ÷2 = 130 x 5 = 650
so you have 650+1170 = 1820 - 1100 cost to make =720 pounds
think this right
4x + 24x - 2 = 7(4x + 2)
Distributive property.
4x + 24x - 2 = 28x + 14
Combine like terms.
28x - 2 = 28x + 14
Like terms cancel
-2 = 14
0 = 16
<h3>The equation is false and has no solutions.</h3>
