Answer:

Step-by-step explanation:

-5x-y=5     since its substitution, take the equation that has the    variables on

x=7y-1         opposite sides(x-7y-1) and sub in whats on the opposite side of the        

-5(7y -1)-y=5    equal sign (7y-1) in for the x variable in the first equation

-35y+5-y=5.  then you distribute the -5 to every value in the parenthesis

-36y=0          then you isolate the remaining variable on one side

y=0               then divide until the variable has no coefficiant

-5x-0=5         then you plug that value back in to the first equation

-5x=5            isolate the variable again

x=-1               then divide again. your y value is 0 and your x value is -1

In a basketball game Fintan made 16 baskets. Each of the baskets is worth either 2 or 3
jekas [21]
Let x represent a 2-point basket, and y represent a 3-point basket.

Basket equation: x + y = 16
Point equation 2x + 3y = 39

Solve using system of equations:
if x + y = 16, then x = 16 - y

Plug into the second equation:
2(16-y) + 3y = 39
32 - 2y + 3y = 39
32 + y = 39
y = 7

So the number of 3-point baskets scored was 7. Hope this helps, let me know if there’s a step you don’t understand! :)

Hi,so I've tried solving this problem for a while and I just don't get it,if you could give me some ideas I would appreciate it.

Answer:

187 cm²

Step-by-step explanation:

The bottom rectangle area is easy, it is 15*9 = 135 cm².

To find the area of the triangle, you only need the base width and its height (you don't need the hypotenuse). You can then use the formula: area triangle is base times half height.

The base width is 15-7 = 8 cm

The height is 22-9 = 13 cm

So the area of the triangle is 13*8/2 = 52 cm²

Together with the 135 of the rectangle that sums to 52+135 = 187 cm².
