Answer:
<em>(1, - 2) </em>
Step-by-step explanation:
2x - y = 4
3x + y = 1
A =
= 2(1) - 3( - 1) =2 + 3 = 5
=
= 4(1) - 1(- 1) = 4 + 1 = 5
=
= 2(1) - 4(3) = 2 - 12 = - 10
<em>x </em>=
=<em> 1</em>
<em>y </em>=
= <em>- 2</em>
<em>(1, - 2)</em>
Answer:
the last one
Step-by-step explanation:
Answer:
The given equation 3x − 7 = 4 + 6 + 4x has one solution.
Step-by-step explanation:
Given : Equation 3x − 7 = 4 + 6 + 4x
We have to find the number of solutions of the given equation.
Consider the given equation 3x − 7 = 4 + 6 + 4x
Simplify, we have,
3x − 7 = 10 + 4x
Now subtract 3x both side, we hvae,
-7 = 10 + 4x - 3x
Simplify, we have,
- 7 = 10 + x
Subtract 10 both side, we have,
-7 - 10 = x
x = - 17
Thus, The given equation 3x − 7 = 4 + 6 + 4x has one solution.
Answer:
Pete runs farther per carry.
Step-by-step explanation:
Given:
Branden and Pete both play running back.
Branden carries the ball 75 times for 550 yards.
Pete had 42 carries for 380 yards
Question asked:
Who runs farther per carry ?
Solution:
First of all we find each boy's distance covered per carry:-
<u>For Branden</u>
Branden carries the ball 75 times for = 550 yards.
Branden carries the ball 1 time for = 
<u>For Pete </u>
Pete carries 42 times for = 380 yards
Pete carries 1 time for = 
As Pete runs 9.05 yards for 1 carry while Branden runs 7.34 yards for 1 carry, hence Pete runs farther per carry.
