1.30(2) + X = 6.10
This would be one of a few equations to do. 1.30(2) represents the cartons of eggs which are each 1.30. the X will represent the price of pancake mix and the total is 6.10.
Answer:
No Solution
Explanation:
5(3 - 9b) = 3(-15b – 2)
Expand
5(3 - 9b): 15 - 45b
3(-15b - 2): -45b - 6
15 - 45b = -45b - 6
Subtract 5 From Both Sides
15 - 45b - 15 = -45b - 6 - 15
Simplify
-45b = -45b - 21
Add 15b To Both Sides
-45b + 15b = -45b - 21 + 15b
Simplify
0 = -21
No Solution
Remark
Make up a proportion that relates the tree and its properties to the stick and its properties.
Givens
Stick height (s_h) = 4
Stick shadow(s_s) = 2
Tree shadow = t_s = 18
Tree height = x
Formula
s_h / s_s = x / t_s
Substitute and solve.
4/2 = x / 18 Cross multiply
4*18 = 2 * x
72 = 2x Divide by 2
72/2 = x
x = 36
The height of the tree is 36 feet.
Answer:
x= -6
Step-by-step explanation:
y=4x-6
y=5x, so where ever you see y, put 5x there.
hence, 5x=4x-6
5x-4x=-6
x= -6
