No. A solution is any co ordinated that lies in the blank space on the graph. (-2,-3) is in the blue shades section so it is not a solution.
1.)
The term (2+8) is the amount of fabric Ali bought. You know this because in the problem, it says that she buys “2 white pieces and 8 blue pieces”
2.)
The terms of the equation are
k and 2f
These are the terms because they are separated by the addition sign
3.) $36
You would first find rate per sand which. To find this, you would do:
9/2
This will give you
4.5. Now, you multiply that by 4. That gives you 36.
4.) The skateboard costs 150
How?
30 is 20% of the price. 20x5=100. So, to find the total amount, you would multiply 30 by 150.
5.) About 50 miles an hour.
You always put distance over time. If you do:
400/8
You get the average rate of 50
6.) 5n
How?
Well, there are five cents in every nickel. So, to find out how many pennies, you would multiply the amount of nickels by 5.
Have a good night :)
The coefficient of y is 14 and the constant is 13.
You can find this by combining like terms first.
6x + 12y + 5 + 2y + 8
6x + 14y + 5 + 8
6x + 14y + 13
Now the coefficient is the number next to y. The constant is the number on its own.
2.5 hours, because 10 miles an hour times 2 = 20 plus half the time? 2.5
