T=b+2c+3j, if b,c,j are 8,3,4 respectively
t=8+2(3)+3(4)
t=8+6+12
t=26
So they chop down 26 trees.
Answer:
P=8.378in
Step-by-step explanation:
Let Distance travelled be P
Time,t=10mins
Lenth of minute hand be l
1 hr= 60 mins, Therefore t is time taken to cover 
I think it the 3 and 4 one ... sorry if I’m wrong
Explanation:
A system of equations are two or more equations that has to be valid at the same time. It means that the variables of one equation can be substitute in the other equation.
For example we have <span>y=5x−8</span> and we can substitute this value of y in the other equation
<span>4x+3y=33</span>
<span>4x+3<span>(5x−8)</span>=33</span> we can solve now for x
<span>4x+15x−24=33</span>
<span>19x=33+24</span>
<span>19x=57</span>
<span>x=<span>5719</span>=3</span>.
y can be obtained from the first equation
<span>y=5x−8</span>
<span>y=5⋅3−8=15−8=7</span>
Then <span>x=3</span> and <span>y=7</span>.
