3=1000 x 1.59 ( we round 2 decimal places) equals to 630. So final answer answer is 1.59.
Step 1: Distribute. On the right side, you should get =2x-4
Step 2: Add all common bases. You should get 4x-5 on the left side
Step 3: Add on each side. For example, add five to each side of the equation. Your equation should look like this; 4x= 2x+1
Step 4: Subtract each x number by 2x. Your equation should be; 2x=1
Step 5: Divide each side by two. Your answer should be x=1/2 or x=0.5
Hope this helped!
Answer:
74.
Step-by-step explanation:
Let the number be xy.
Then from the given data
x = y + 3..........(1)
The numerical value of xy is 10x + y so the second equation is
10x + y + 10y + x = 121
11x + 11y = 121 Simplifying:
x + y = 11
x = -y + 11 .........(2) Adding equations (1) and (2):
2x = 14
x = 7
and therefore y = 7 - 3 = 4.
