Overall, they spent 3 3/4 hours fishing and swimming.
Step-by-step explanation:
1. when x is 0
y will be
4x+2y=10
4(0)+2y=10
0+2y=10
collect like terms
2y=10-0
2y=10
divide both sides by 2
2y/2=10/2
y=5
so when x =0 y will equal to 5
2. when x is 1
y will be
4x+2y=10
4(1)+2y=10
4+2y=10
collect like terms
2y=10-4
2y=6
divide both sides by two
2y/2=6/2
y=3
so when x is 1, y is 3
3. when x is 2
4x+2y=10
4(2)+2y=10
8+2y=10
(CLT) 2y=10-8
2y =2
y= 1
7(x-1)=70/10
7x-7=7
7x=14
x = 2
The number is 2.
No it’s not a right triangle
Hey I would first do the one in parentheses so 7-5 is 2 so your equation is now 60/5*2 so now what will you do?
