Answer:
just give the question to much work
Step-by-step explanation:
Triangle
m<A + m<B + m<C = 180
8x +12 + 5x+14 + <span>2x +4 = 180
15x + 30 = 180
15x = 180 -30
15x = 150
x = 10
m<A </span><span>= 8x +12
</span>m<A = 8(10) +12
m<A = 80 + 12
m<A = 92
answer
m<A = 92
Answer:
3/8 because 1/8 is .125 multiply by 3 and u get .375 aka 3/8
Answer:
only one solution
Step-by-step explanation:
Complete question:
<em>Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. 2x − y = 2 3x + y = −6 one and only one solution infinitely many solutions no solution Find the solution, if one exists. (If there are infinitely many solutions, express x and y in terms of the parameter t. If there is no solution, enter NO SOLUTION.) (x, y) </em>=
Given the expression
2x − y = 2 .... 1
3x + y = −6 ..... 2
We are to determine the number of solution the equation has:
Add equation 1 and 2
2x + 3x = 2 - 6
5x = -4
x = -4/5
Substitute x = -4/5 into 1
From 1: 2x − y = 2 .... 1
2(-4/5) - y = 2
-8/5 - y = -2
-y = -2+8/5
-y = -10+8/5
-y = -2/5
y = 2/5
<em>Since the value of x and y are just 1 hence the system of equations has ine solution</em>
Answer:
Option (2). 
Step-by-step explanation:
The given expression is [
]
We can rewrite the fractions as,
= 
Now we will substitute the fractions in the expression,
![[-(5+\frac{1}{4})]-[-(7+\frac{1}{2})]](https://tex.z-dn.net/?f=%5B-%285%2B%5Cfrac%7B1%7D%7B4%7D%29%5D-%5B-%287%2B%5Cfrac%7B1%7D%7B2%7D%29%5D)
= 
= (-5 + 7) + 
= 2 + 
= 2 + 
=
Therefore, Option (2). will be the answer.
