For the first one c-9=(2)(4)+6
You are gonna multiply 2 and 4 first, 2*4=8. Now you have c-9=8+6. 8+6=14. So now the equation is c-9=14. Now we are going to add 9 to both sides. So c=23
For the second equation 10+y=90. We are going to subtract 10 from both sides. So, y=80.
Third, add 4 to both sides. a=10.
Fourth, subtract 8 from both sides. d=-9
Fifth, 5+2(3+4)=-x.
First we are going to add 3 and 4. 3+4=7. 5+2(7)=-x. Next we are going to multiply 2 and 7. 2*7=14. 5+14=-x. 5+14=19. So our equation is 19=-x. Next we are going to multiply both sides by -1. Making our final equation x=-19.
c=23
y=80
a=10
d=-9
x=-19
I hope that helps, if you need any further explanation just ask.<span />
What you can do is count all the shapes the put the number of blue with that into a fraction. Lets say that there are 24 shapes and 15 are blue the fraction would be 15/25
Hope this helped. If you post a pic I can help you more.
Answer:
m = 300
Step-by-step explanation:

multiply both sides of the equation by 5

Answer:
the question is asking you to find the area i.e length of the angle and for that you have to find out the length of the xy and kz by making equations.
you can do Xy=Kz as they are parallel lines and i think the answer will be 5m and after finding the length do the following process
No, 1/2 is bigger than 1/3 because:-
1/2 = 3/6
1/3 = 2/6
Compare
3/6 is larger, which means 1/2 is larger since they both equal each other.
Answer: 1/2 is greater than 1/3
