You need to add all of the numbers up
Answer:
Simplifying
6x + -2y = 30
Solving
6x + -2y = 30
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
6x + -2y + 2y = 30 + 2y
Combine like terms: -2y + 2y = 0
6x + 0 = 30 + 2y
6x = 30 + 2y
Divide each side by '6'.
x = 5 + 0.3333333333y
Simplifying
x = 5 + 0.3333333333y

Step-by-step explanation:
1. add the numbers all together
(of the pets)
= 40 pets total
40 pets =100%
1 pet = 2.5%
percents:
Cat= 10, or 25%
Dog = 15, or 37.5 %
fish=8 or 20%
bird= 7 or 17.5%
angles:
dog= 135
cat= 90
fish= 72
bird= 63
Answer:
-3.25 >-2.5 +r
Option 4 is right.
Step-by-step explanation:
Given picture is a graph of number line representing the area to the left of -0.75 not including -0.75
i.e. the graph shows r<-0.75, where r is a variable
Subtract 2.5 to both the sides
we get
-2.5+r <-0.75-2.5
or -2.5+r <-3.25
Or -3.25 >-2.5 +r
Option 4 is right.
Why other options are wrong:
i) 3.25<r+2.5. 0 satisfies this inequality but not included in the graph. Hence wrong.
ii)3.25>2.5+r
r=0 satisiffes this contradicting the graph again.
Thus second option is right.
iii) -3.25<-2.5+r
Here r =0 satisfies this equation contrary to graph. Hence option iii is wrong.
