Answer:
Part A
20x + 25y = 210 --> D.
Part B
If jane purchased exactly 4 shirts she must have purchased Exactly ___ skirts. (round to the nearest tenth)
20*4 + 25y = 210 --> y = 5.2
is it possible for jane to purchase exactly 4 shirts? ____(yes or no)
no, because she can't buy 5.2 skirts.
Sin2x=2sinxcosx, cos2x=1-2sin^2x
sin(2x)+cos(3x)=2sinxcosx+cos(x+2x)
cos(x+2x)=cosx(1-2sin^2(x))-sinx2sinxcosx
sin(2x)+cos(3x)=2sinxcosx(1-sinx)+cosx(1-2sin^2(x))
111 would be the y-intercept. This is because 111 is on the y-axis.
3+8+10+14+11= 46
46/(how many trees) 5= 9.2
9.2 years is your answer.
Percent means parts out tof 100 so 15%=15/100
divide by 5/5
3/20=lowet terms
