To cube a number, just use it in a multiplication 3 times .
A cube root goes the other direction:
3 cubed is 27, so the cube root of 27 is 3
This is the answer for you problems
Answer:
x = 5
Step-by-step explanation:
The sum of interior angles in a triangle is 180°
91° + 10x - 4° + 8x + 3° = 180° add the like terms
90° + 18x = 180°
18x = 180° - 90
18x = 90° divide both sides by 18
x = 5

Answer:
x= 1
y= -2
Step-by-step explanation:
equation (1): y= -3x+1
equation (2): y=x-3
solve the system of equations by substitution:
step1: sub ( x-3 ) for y in equation 1:
y = -3x+1
x-3 = -3x+1
step2: simplify the equation to get x:
(add 3 for both sides)
x = -3x+4
(add 3x for both sides)
4x = 4
(divide 4 from both sides)
x = 1
step3: sub the value of x (x=1) in equation 2:
y = x-3
y = 1-3
step4: solve the equation to get y:
y = -2
