£1.60 each notebooks
3 pencils times 21p= 63p
2pens times 37p=74p
3sharpeners times 86p=258p
63p+74p+258p=£3.95
£8-3.95=£4.05
£4.05-£1.60= £2.45
£2.45-£1.60=85p
So… he bought 2 notebooks

Answer:
b) 91
Step-by-step explanation:
<u>Step 1: Multiple marks by its weights</u>
<em>Homework average:</em> 95 x 20% = 19
<em>Quiz average: </em>90 x 20% = 18
<em>Test average:</em> 87 x 40% = 34.8
<em>Final exam:</em> y x 20% = 0.2y
<u>Step 2: Add all weighted averages and find y</u>
19+18+34.8+0.2y = 90
71.8 + 0.2y = 90
y = 18.2/0.2
y = 91
Therefore, Anna needs to score minimum 91 in the final exam so that she can score a 90 in class.
Option b is correct.

Answer:
The answer is C or (3) × (17.25) = 51.75; He spent $51.75.
Step-by-step explanation:
i say this because 17.25 time 3 equal 51.75
Wow, lots of points, easy qeustion and nobody anwering
ok so
basically solve for y
6x+4y=700
minus 6x from both sides
4y=-6x+700
divide both sides by 4
y=-3/2x+175
ok so
y=mx+b
m=slope
b=yintercept or where the line crosses the y axis
so
y=-3/2x+175
yintercept is 175 so go 175 units up on teh y axis and put a point there
slope is -3/2
slope=rise/run
go 3 units down and 2 units to the right from that first point you ploted
that is new point
connect the 2 points to get graph, or input a value for x and get a value for y to get a point
basically just find 2 differn points and connect them to graph
I have attached graph
