Answer:
x = 6
y = -9
x = -25
Step-by-step explanation:
<u>1st Equation</u>
Step 1: Write out equation
3(4x - 3) - 19 = 8x - 4
Step 2: Solve
12x - 9 - 19 = 8x - 4
12x - 28 = 8x - 4
4x - 28 = -4
4x = 24
x = 6
<u>2nd Equation</u>
Step 1: Write out equation
-6y + 14 = 32 - 4y
Step 2: Solve
-2y + 14 = 32
-2y = 18
y = -9
<u>3rd Equation</u>
Step 1: Write out equation
-28 + 5 - 3x = 2 - 2x
Step 2: Solve
-23 - 3x = 2 - 2x
-23 = 2 + x
-25 = x
x = -25
Answer:
41
Step-by-step explanation:
41/6*6
41*6=246
246/6=41
Answer:
b n-65
Step-by-step explanation:
because its 65 less than n
Let the measures of the base angles be x, and the measure of the vertex angle be y.
y is bisected, and "each resulting angle is 51 degrees larger than a base angle"
y/2=x+ 51, thus y=2x+102°.
The measures of the interior angles are x-x-(2x+102)
The sum of the measures of the interior angles of any triangle is 180°, thus we have:
x+x+2x+102°=180°
4x=180°-102°
4x=78°
x=78°/4=19.5°
The measure of the obtuse angle is 2x+102°=2*19.5°+102°=141°
Answer: 141°
Calculus is a form of math its not a problem so there would be no formula
