Answer:
(-5, 3)
Step-by-step explanation:
Elimination seems like the best method to use here.
x+y=-2
x-y=-8
---------
2x=-10
Divide everything by two
x=-5
Now plug it back into one of the original equations,
-5+y=-2
Add 5 to everything
y=3
Answer:
105
Step-by-step explanation:
500 goes into 100, 5 times
21 times 5 is 105
So 21/100 is equal to 105/500
Or you can do
500*0.21=105
Answer:
Isoceles Obtuse
Step-by-step explanation:
This triangle has 2 sides with the same side lengths and 2 of the same angles, so it is an isoceles triangle. Is it obtuse or actue? Well, we can see that there is an angle greater than 90 degrees, so this is an obtuse isoceles triangle.
Answer: 3,220
Step-by-step explanation: What you do first is find the volume of the room which is 1,610. So after that you multiply 1,610 by 2 since Maria wants "two" coats of paint on each wall.
Answer:
A) 1
Step-by-step explanation:
To solve, just plug in the numbers to the equation for x until both sides are equal to each other.
Plug in 1:
2(1 + x) = x + 3
Let x = 1:
2(1 + 1) = 1 + 3
Solve. Remember to follow PEMDAS. First, add parenthesis, then multiply. On the other side, add:
2(1 + 1) = 1 + 3
2(2) = 4
4 = 4 (True)
A) 1 is your answer.
