The solution to the system of equations is x = -1 and y = -1
<h3>How to solve the following
system of equations?</h3>
The system of equations is given as:
2x + 3y = 1
5x - 4y = 14
Multiply 2x + 3y = 1 by 2.5
So, we have:
5x + 7.5y = 2.5
Subtract 5x + 7.5y = 2.5 from 5x - 4y = 14
So, we have
7.5y + 4y = 2.5 - 14
Evaluate the difference and the sum
11.5y = -11.5
Divide by 11.5
y = -1
Substitute y = -1 in 2x + 3y = 1
2x + 3(1) = 1
This gives
2x + 3 = 1
Subtract 3
2x = -2
Divide by 2
x = -1
Hence, the solution to the system of equations is x = -1 and y = -1

Answer:
6 seconds
======================================================
Step-by-step explanation:
let the entire length of path x
The object travels (1/8) of the length of the path (3/4) in second.
using the ratio and proportion to find the total time does it take the object to travel the entire length of the path as following
Length : time
1/8 x : 3/4 sec.
x : (total time)
using scissors metod
Total time = x * (3/4) / ( 1/8 x) = (3/4) / (1/8) = 6 seconds
Answer:
C
Step-by-step explanation:
A cube has 6 square faces
Each face: 5² = 25
Surface area: 6(25) = 150 in²
Answer:
31/40 of the trail
Step-by-step explanation:
he completed 9/10 of the trail (or 72/80 because 9*8 is 72)
He went back 1/8 of the trail (or 10/80 because 1*10 is 10)
72-10 is 62
he went 62/80, simplified is 31/40 of the trail
