Answer:
41
Step-by-step explanation:
the 2 triangles are same so the angles would be also same. 180-86-53= 41
Given the system of equations:
To solve it by substitution, follow the steps below.
Step 1: Solve one linear equation for x in terms of y.
Let's choose the second equation. To solve it for x, add 3y to each side of the equations.
Step 2: Substitute the expression found for x in the first equation.
Step 3: Isolate y in the equation found in step 2.
To do it, first, add 48 to both sides.
Then, divide both sides by 15.
Step 4: Substitute y by 5 in the relation found in step 1 to find x.
Answer:
x = -9
y = 5
or (-9, 5)
Also, you can graph the lines by choosing two points from each equation, according to the picture below.
(-7,0) (0,-7) should be the zeros
Answer:
9.929
Step-by-step explanation:
-1.091 + 12.12 = 11.029
11.029+(-1.1) = 9.929
