Step-by-step explanation:
to write a line equation we need minimum of two points. basicaly a line is written in the form y=mx+c where, m is the slope of the line and c is the intercept made by the line on x-axis (OR) or if two points (x1,y1) and (x2,y2) are given then we can form a line equation as (y-y1)= (y2-y1)*1/(x2-x1) *x-x1 (OR) (y-y2)= (y2-y1)*1/(x2-x1) *x-x2
First you have to remember that to find a percentage you can multiply a number by the percentage's decimal form, for example 40% of 100 would be .40 * 100.
Anyways, 24*.40 =9.6.
To find the percentage however, you must divide 24/40 which equals 0.6, which is equal to the percentage 60%.
To find the third question, you must multiply 24 by 2.5 (0.4 * 2.5 = 1) and you should get 60.
The last question you may have made a typo on, you repeated the first question.
Answer:
=656
Step-by-step explanation:
Evaluate for a=5,b=9
3(52)(9)+1−20
3(52)(9)+1−20
ps. there is no c
Answer: 2.4 * 10^1
Step-by-step explanation:
Divide the two numbers. 4.8 * 10^3 = 4800
4800/200 = 24
Put into scientific notation
24 = 2.4 * 10^1
4.8 * 10^3 is 24 (2.4*10^1) times greater than 200
