Answer:
1 ruler costs £4 and 5 rulers cost £20
Let x be the yearly salary of an architect. Then the yearly salary of a lawyer is 2x-20000.
We can build an equation now! x+(2x-20000)=211000, because the yearly salary of an architect plus the yearly salary of a lawyer is 211000.
We combine like terms to get 3x-20000=211000.
We add 20000 to both sides to get 3x=231000.
We divide both sides by 3 to get x=77000, so the average yearly salary of a lawyer is 77000.
Then, the average yearly salary of an architect is 2(77000)-20000=154000-20000=134000, so the average yearly salary of an architect is 134000.
Answer:
<h2>y=8</h2>
Step-by-step explanation:
4y-4=28
4y=28+4
4y=32
y=32/4
y=8
now plug in 8 for y and check the equation true:
4y-4=28
4*(8)-4=28
32-4=28
28=28
So, y is equal to eight 8

Answer:
£81 <u>if she only worked for 7 1/2 hours for the entire week.</u>
£567 <u>if she worked for 7 1/2 hours a day</u> for the entire week.
Step-by-step explanation:
So, she makes £10.80 an hour. £10.80 x 7 1/2 = £81. So she makes £81 every day she works for 7 1/2 hours with that rate. So she'd make £567 if she worked for 7 1/2 hours every day. OR if she only worked 7 1/2 hours in total for that week she only made £81.
<u>Hope this helps and have a nice day!</u>
