Answer:


Step-by-step explanation:

Let x be the number of buses and y be the number of vans.

We know that there are 5 more buses than vans, therefore, we can set up:

x=y+5

Since a bus transports 55 people and a van transports 12 people, therefore, we can set up:

55x+12y = 409\\

Now lets solve the above two equations together by substitution

55(y+5)+12y = 409\\\\55y+275+12y=409\\\\67y+275=409\\\\67y=409-275\\\\67y=134\\\\y=2,x=2+5=7

Total number of students and teachers who rode to the zoo in buses=55*7=385

Total number of students and teachers who rode to the zoo in vans=12*2=24

Solve the following equations for x, if possible. check your solutions. 6/dividex+2 = 3/4
SOVA2 [1]

Solving \frac{6}{x+2}=\frac{3}{4} we get x=6

Step-by-step explanation:

We need to solve \frac{6}{x+2}=\frac{3}{4}

Solving:

Cross multiply both terms:

4*6=3(x+2)\\24=3x+6\\3x=24-6\\3x=18\\x=18/3\\x=6

Verifying the solution:

Putting x=6 in the question given:

\frac{6}{x+2}=\frac{3}{4}

\frac{6}{6+2}=\frac{3}{4}

\frac{6}{8}=\frac{3}{4}

\frac{3}{4}=\frac{3}{4}

Solving \frac{6}{x+2}=\frac{3}{4} we get x=6

SA=2(5+4+3)

SA=2(12)

SA=24

#2

SA=bH+2LS+bL

SA=4+2x7+8

SA=4+14+8

SA=25

#3

SA=2(LW+LH+WH)

SA=2(13+17+2)

SA=2x32

SA=64

(the rest of the shapes

i can't see but you can use that formula to do it <3 GL!)
