Answer:
Given = 6 x 0 = 0
Step 2 = Substitute. Any number plus its opposite equals 0 (10 +-10)
Step 3 = Use the distributive property
Step 5 = Subtract 60 from both sides
Step 6 = Simplify to solve for 6 x -10
Answer:
You mean ×3? if it is so 5-3x-3y. Hope it's correct
Let's make some variables to represent the cost of the tables and chairs.
Let x be equal to the cost of one chair
Let y be equal to the cost of one table
The total cost for 3 chairs and 2 tables is $17.
3x + 2y = 17
The total cost for 8 chairs and 4 tables is $37.
8x + 4y = 37
Now we have our system of equations.
Let's solve it.
3x + 2y = 17
8x + 4y = 37
We can cancel the y's very easily. Then it would just leave us with the x's.
Multiply the top equation by -2.
3x(-2) + 2y(-2) = 17(-2) =
-6x - 4y = -34
Then add the equations together.
-6x - 4y = -34
8x + 4y = 37
=
2x = 3
Then just divide both sides by 2.
x = 1.5
Substitute 1.5 into one of the equation. I'll pick 3x + 2y = 17
3(1.5) + 2y = 17 ; Start
4.5 + 2y = 17 ; Multiply 3 and 1.5 together
2y = 12.5 ; Subtract 4.5 from each side of the equation
y = 6.25 ; Divide both sides by the coefficient of y. Which 2
So, a chair costs $1.50 and a table costs $6.25.
Answer:
Skewed left
Step-by-step explanation:
The graph is skewed left because there are many points on the left side of the graph, but only a few on the right side.
Hope this helps!
Hi! the first one is -2+6 i & the second one is parallelogram!
