Answer:
a. £564
b. £141
Step-by-step explanation:
a. Firstly, we add up the ratios
= 5 + 4 + 3 = 12
Amanda’s share was 5
Let the total amount be £x
Thus; 5/12 * x = 235
5x = 12 * 235
x = 2820/5 = 564
The total cost of the holiday is £564
b. We want to calculate what Bethany paid
That would be 3/12 * 564 = £141
For this case, what you must do is perform the following division:
N = (U.S. flags.) / (Total flags)
We have then:
N = 12/45
Simplifying:
N = 4/15
Answer:
The fraction of George's magnets are U.S. flags is:
N = 4/15
Answer:
(x, y) = (4, 16)
Step-by-step explanation:
The first equation is a proportion, so you know right away that (0, 0) is on the graph. Pick any value you like for x, and y will be 4 times that. So, for example, the point (5, 20) will also be on the graph of y=4x.
The second equation has a y-intercept of 20 and a slope of -1. So, however many unit to the right of the y-axis you choose to go, the y-value will be down that number of units from 20. In addition to (0, 20), the point (5, 15) will be on the graph of y = -x+20.

Personally, I like to use a graphing calculator to show the graphical solution.
Here, the solution is (x, y) = (4, 16).
Answer:
9
Step-by-step explanation:
2x-9+x-2=16
3x-11=16
3x=27
x=9
Answer:
10.24 in²
Step-by-step explanation:
First we need to know how to find the area of a rectangle, which is base * height.
We can notice that the base and height are both 3.2, so we multiply 3.2*3.2.
To do this, we first have to completely ignore the decimal points. Just pretend you're multiplying 32*32, to get 1024. Then, we count how many numbers are past the decimal point on each number. On both, there is 1 number past, and we add those together to get 2 numbers past the decimal point.
We then, finally, make the number we got (1024) have 2 numbers past the decimal point, so instead of 1024, we have 10.24, which is our answer!
