Let x represent the number of US dollars required. From the information given,
1.2 Australian dollars equals one us dollar
Thus,
22 Australian dollars = x US dollars
We would have the following equations
1.2 = 1
22 = x
By crossmultiplying, we have
x * 1.2 = 1 * 22
1.2x = 22
Dividing both sides of the equation by 1.2, we have
1.2x/1.2x = 22/1.2
The expression that can be used to convert 22 Australian dollars to US dollars is
x = 22/1.2
Answer:
y=8x-23
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Given that the slope is 8, m=8.
subst. m=8 into the equation:
y= 8x +c
To find c, substitute a coordinate.
When x=3, y= 1,
1= 8(3) +c
1= 24 +c
c= 1 -24
c= -23
Thus, the equation of the line is y= 8x -23.
I cant help you here. I am bad at math!!!
An easy way (you must put the numbers in the correct side)
3 2 you cant subtract 5 from 2 so u carry one
-1 5 the 3
2 ¹3. it should look like this.Now u do 13-5=8
-1 5
2 ¹3. now u do 2-1=1
- 1 5
= 1 8
your final answer is 18.
