It is said the blue card is a rectangle, so you don’t have to minus the inside rectangle. :)
Step-by-step explanation:
you plug 0 into the (x,y) into the equation. if your finding x you plug in 0 for y and versa.
so y = 9x -3 im going to find x
0 = 9x -3 subtract -3 from both sides
-3 = 9x divide by 9
x = -3
I think 4. is 2 and 4. but I'm not entirely sure because I haven't done factors in a long time.
12 x pie (I can’t fine the symbol for it tho)
John caught 18 fishes and Peter caught 30 fishes.
Step-by-step explanation:
Let,
Fishes caught by John = x
Fishes caught by peter = y
Total fishes caught = 48
According to given statement;
x+y=48 Eqn 1
x=
Eqn 2
Putting Eqn 2 in Eqn 1;

Multiplying each term by 5;

Dividing both sides by 8

Putting y=30 in Eqn 1

John caught 18 fishes and Peter caught 30 fishes.
