The answer is :his average is increase by 12
Answer:
2225 I think just do 685+1570
3 3/4 + 3 1/4 =7+3 =10
1/4+1/4+1/4= 3/4 or 1/4 * 3=3/4
The 2 little lines on each side of the triangle mean that the two sides are equal.
Because the two sides are equal the two bottom inside angles are also the same.
The left bottom angle is given as 68, so the bottom right is also 68.
The three inside angles of a triangle need to equal 180.
So X = 180 - 68 - 68
X = 44
A.) graph of two lines that intersect at the point negative 1, 1, with text on graph that reads One Solution negative 1, 1
Step-by-step explanation:
The two simultaneous equation given are;
y+2x= -1
3y-x=4
multiply the first equation by 1 and the second equation by 2 to make the terms with x equal
y+2x = -1
6y-2x=8
-------------- ---add the terms with x to eliminate x
7y=7 -------divide both sides by 7 to remain with y
7y/7 =7/7
y= 1 -----use the value of y in the first equation
y+2x= -1
1+2x= -1
2x= -2
2x/2= -2/2
x= -1
The solution is (-1,1)
You can plot the equations on a graph tool as shown below to visualize the solution where the two linear equations intersect
