Answer:
x = -4/11
Step-by-step explanation:
add the x values.
11x+8=4
subtract 8 from each sides
11x=-4
divide by 11
x=-4/11
Answer:
No.
Step-by-step explanation:
This is because 5:2 could mean there are 5 circles to 2 triangles and 2:5 could mean 2 circles to 5 triangles.
5 circles is not the same as 2 circles as 2 triangles is not the same as 5 triangles.
Answer:
Either :
1/2 10x+1/2 20y+1/2 10z
or
5x+10y+5z
Step-by-step explanation:
You're just multiplying everything by 1/2
Standard form is
ax+by=c
where a,b,c are integers
y+3=1/4x
timesboth sides by 4
4y+12=x
minus x both sides
-x+4y+12=0
minus 12 both sides
-x+4y=-12
(I like x to be positive so)
times both sides by -1
1x-4y=12
a=1
b=-4
c=12
A = 0.1
B = 50.9
These are rounded to the nearest tenth
