Standard form Is what is shown in the picture I’ve provided. To get that from this equation you have to move the -1/4x to the other side. Since your moving it across the equal sign it has to change signs and it becomes positive now. So the answer for this question would be:
1/4x+y=10
Hope this helps :)
Answer:
I think it -2/5
Step-by-step explanation:
Answer:
2.25
Step-by-step explanation:
Change the fraction so that the denominator is something that's a factor of 100
9/4 = x/100
9 x 25 = 225
-----------------------
4 x 25 = 100
225/100
Now divide to get your decimal
225/100 = 2.25
Answer:
1 3/5 = 8/5
.2=2/100
Step-by-step explanation:
make an equality:
x/(8/5)=2/100
it kinds looks weird on here but write it out on paper
then cross multiply:
100x=(2)(8/5)
100x=16/5
now divide each side by 100:
x=4/125
same for the second one:
make an equality:
x/2=2/100
cross multiply:
100x=(2)(2)
100x=4
x=1/25
Answer:
A) Because A and E are perpendicular therefore making B 90 degrees. D same for DBC
B) Same as A. for A
C) because they are perpendicular to eachother
D) Because they are the same angle they are equal to eachother
E) We assume that they are both 45 degrees thus making them equal to eachother
