Answer:
D, 0.19
Step-by-step explanation:
So first you add up all the candies
you’ll get 79 pieces of candy
So 4 pieces of green candy
So we can just subtract 4 from 79 you’ll get 75 pieces
It still works becuase we know that 4 pieces gone are green so the other candies still have the same amount
Now there are 14 red pieces
So 14/75
Now simplify that and you’ll Get
0.18666666
Now round that, 0.19
1: (-1,-1) is (x, y) to see if it is a solution, you would just plug in x and y and see if the equation is true.
-4 (-1) + 2(-1) = 2
4 + -2 = 2
2 = 2 CORRECT
So... plug in x and y in the second equation to Make sure it works for that one too.
-1 + -1 = -2
-2 = -2 CORRECT
So, yes. (-1,-1) is a solution to both equations.
Answer:
$720
$360
Step-by-step explanation:
Let the cost of couch be A and that of coffee table be B
Given couch and coffee table cost $1080
That’s
A + B = $1080
Also, the cost of couch A is 2 times the cost of coffeee table B.
That’s
A = 2B
We now have two equations
A + B = 1080
A = 2B
Now ,substitute 2B for A in the first equation .
We have
A + B = 1080
2B + B = 1080
3B = 1080
Divide both sides by 3
3B/3 = 1080/3
B = 360
The coffee table cost $360
Remember A = 2B
Therefore
A = 2 x $360
A = $720
The couch cost $720 while the coffee table cost $360
Answer:
12 divided by 2 + 4 - 2 x 3 is 4
