Answer:
70
Step-by-step explanation:
1) "20% of a number is 56"
Lets call this number "x".
0.20x = 56 (percents can become decimals by dividing 100)
2) 45% of the same number is 126
This will be the same number "x".
0.45x = 126
3) Divide by 0.45 (you can use a calculator)
0.45x / .45 = 126 / .45
x = 280
4) "25% of that number"
that number is x
25% is one-fourth of a number so
0.25x = 280/4
0.25x = 70

Answer:
2.857
Step-by-step explanation:
The slope is -5
To find slope you can use point slope form.
first you use the equation (y-y1)=M(x-x1)
then you change that equation to y=mx+b
Since both numbers are under the square root sign they can be combined under 1 sqrt sign.
Now all you need do is perform the division under the root sign
sqrt(4) is your answer but not the final one.
