Answer:
£90
Step-by-step explanation:
Given the ratio of 5:1, total denominator is 5+1=6. Therefore, Natasha's proportion is 5/6 while Richard gets 1/6.
The differences in proportion is 5/6-1/6=4/6
This difference of 4/6, simplified as 2/3 is equivalent to £60
Therefore, 3/3=1 is given by cross multiplication
Total proportion is £60*3/2=£90
In this case, Natasha gets 5/6 of 90=5/6*90=75 while Richard gets 1/6 of 90=1/6*90=15
The difference is 75-15=60
In concljsion, they altogether get £90
Answer:
Step-by-step explanation:
The problem here is that the question is not clear. In particular, what does "2)" mean?
Reflecting across the x axis is easy. Think of the x axis as a mirror. when you look in a mirror, your image is behind the mirror the same distance you are in front of the mirror. So, to reflect across the x axis, just multiply all the y values of the points by -1. For the reflection part
(-3,4) becomes (-3,-4)
(1,2) becomes (1,-2)
(-2,1) becomes (-2,-1)
Step 2 probably is a translation, but it is not clear what it is - so I cannot help you further.
If you get step 2 straight, the dilation by 3 is achieved by multiplying all the x and y values by 3.
