Hi! 5.5 x $8 is equal to $44
Step-by-step explanation:
hope this helped
65 I think
So I did 4•5=20 and 9•5=45 and added 20+45 which equals 65
<span>15x-3y=27
5x+4y=14
multiply (2nd) equation by (3)
15x + 12y = 42
</span>15x - 3y=27
15x + 12y = 42
-------------------substract
-15y = -15
y = 1
15x-3y=27
15x-3(1)=27
15x - 3 = 27
15x = 30
x = 2
so now you have x = 2, y =1

Answer:
a.
cm or 7.21cm
b.
cm or 13.04cm
c. x=
cm or 11.66cm, y=
cm or 13.82cm
Step-by-step explanation:
a. You have to find the length of the other two sides of the triangle using the information already given. The first side is 6cm and the other is 12-9=4cm. Because it's a right-angled triangle you can use pythagoras

b. You can use pythagoras again because it's a right-angle triangle

c. In this question you have to find x and y. We need to find x first using pythagoras

Now that we've found x we can find y using pythagoras but instead of find c, we will find another side

Hope this helps :)
