We got the value of 
by solving the given equations 
and 
by reduction method.
<h2>
What is reduction method?</h2>
The reduction or elimination approach includes using arithmetic operations between equations to produce equivalent equations with fewer unknowns that are simpler to analyze and evaluate.
Given equations are
.........(1)
...........(2)
We need to find the value of 
Simplifying the given equation (2) and we get
................(3)
Now, substitute the equation (3) in equation (1) and we get
Substitute the value of x in equation (3), we get
Now adding the values of x and y, we get
![\therefore e=\frac{26}{7}+\frac{52}{7}\\\Rightarrow e=-{[\frac{26+52}{7}]\\\Rightarrow e={[\frac{78}{7}]](https://tex.z-dn.net/?f=%5Ctherefore%20e%3D%5Cfrac%7B26%7D%7B7%7D%2B%5Cfrac%7B52%7D%7B7%7D%5C%5C%5CRightarrow%20e%3D-%7B%5B%5Cfrac%7B26%2B52%7D%7B7%7D%5D%5C%5C%5CRightarrow%20e%3D%7B%5B%5Cfrac%7B78%7D%7B7%7D%5D)
Therefore, the value of .

Carla paid more but got more. if she would have got the same amount as Bobby she would have paid less $2.64
Answer:
12z + 6
z = -1/2
Step-by-step explanation:
y(3z+2)
4(3z+2)-2
(12z + 8) -2
12z + 8 - 2
12z + 6
If going further,
12z = -6
z = -1/2
Answer:
8.0 seconds to the nearest tenth,
Step-by-step explanation:
h=-16t^2 +vt + c.
-16t^2 + 116t + 101 = 0
t = [ -116 + /- √(116^2 - 4*-16*101) ] / (-32)
t = (-116 +/- √19920) / (-32)
t = -0.79, 8.036 (we ignore the negative root)
The time in flight = 8.036 seconds.
If there is 8 ice cream sandwiched with 2 pints in each just multiply and it's 16 pints. A strategy you can use is the count on strategy for example -
2,4,6,8,10,12,14,16
