Answer:
x = -8
y = 7
Step-by-step explanation:
5x + 7y = 9
2x - 3y = -37
1.) First, multiply each side to match either y-values or x-values. (In this example, we'll use match x-values)
10x + 14y = 18 (multiplied by 2)
10x - 15y = -185 (multiplied by 5)
2.) Then, subtract the entirety of one equation to isolate the y-value.
10x + 14y = 18
-10x + 15y = 185
3.) Add and subtract values and divide to find y.
29y = 203
y = 7
4.) Plug-in y to solve for x into one equation, or repeat steps 1-3.
15x + 21y = 27
14x - 21y = -259
29x = -232
x = -8
How many solutions does this have?
for every value of x, it has no solution.
using proportion in similar triangle, then
let x be the length of the tower's shadow
= ( cross- multiply )
9x = 113.4 ( divide both sides by 9 )
x = = 12.60 m ( to the nearest hundredth )
Answer: 12.6
Step-by-step explanation: Each ticket individual for 6 plays would cost 12.6.
Hope this helps!
Answer: You are correct.
Step-by-step explanation: You are correct because 126 divided by 6 equals 21.
