Answer:
Horseback riding costs $30 and parasailing costs $51, so B.
Step-by-step explanation:
This is answered by using simultaneous equations, let x be parasailing and y be horseback riding.
3y + 2x = 192
2y + 3x = 213
Multiply each equation by the number in front of the y of the other equation:
2 x (3y + 2x = 192)
3 x (2y + 3x = 213)
Which results in:
6y + 4x = 384
6y + 9x = 639
Simply minus the two equations to get rid of the y:
6y - 6y = 0
4x - 9x = -5x
384 - 639 = -255
The negatives cancel out which give a result:
5x = 255
x =
x = 51
So parasailing costs $51
Now you can simply plug this value into one of the equations:
3y + (2 x 51) = 192
192 - 102 = 3y
90 = 3y
y =
y = 30
So horseback riding costs $30!
Hope this helps.
Answer:
The answer is B, 384. Cu cm.
Step-by-step explanation:
This is because you can split this figure into two separate rectangles. The first one has a depth of 2 width of 14 and length of 12 so you multiply L x W which is equal to 168. Then since you want the depth also you multiply 168 x 2 = 336. Next you solve for the last rectangle and add them together. So for this the equation is 2(6 x 4) = 48. 336 + 48 =384.
Hope this helps.
