Answer:
3985
Step-by-step explanation:
Note: predecessor means a number before for example predecessor of 4 is 3. Similarly, successor is a number after for example the successor of 4 is 5.
The predecessor of the predecessor of 2987 = 2987-2 = 2985
Let 2985 be x
The greatest 3 digit number = 999
And the successor of the greatest 3 digits number would be = 999+1 = 1000
let 1000 be y
We have find the sum of x and y
= 2985+1000
= 3985
Answer:
4
Step-by-step explanation:
Significant figures are whole numbers, without any decimals, the four numbers are therefore significant.
Answer:
x = 6, y = 5
Step-by-step explanation:
5x - 4y = 19 -------> equation 1
x + 2 = 8 --------> equation 2
<u>Step 1</u> : Subtract 2 on both sides in equation 2.
x + 2 - 2 = 8 - 2
x = 6
<u>Step 2</u> : Substitute the value of x is equation 1.
5 ( 6 ) - 4y = 19
( 5 * 6 ) - 4y = 19
30 - 4y = 10
<u>Step 3</u> : Subtract 30 on both sides.
30 - 30 - 4y = 10 - 30
- 4y = - 20
<u>Step 4</u> : Multiply - 1 on both sides.
- 1 * - 4y = - 1 * - 20
4y = 20
<u>Step 5</u> : Divide 4 on both sides.
4y / 4 = 20 / 4
y = 5
<u>Hence</u>,
x = 6
y = 5
