Answer:
Phoebe:180
Polly:30
Andy:60
Step-by-step explanation:
Shorten them as
Polly:x
Phoebe:y
Andy:z
y=3z
z=2x
y=6x
Subsituting:x+y+z----->3x+y----->9x
9x=270 x=30 y=180 z=60
By solving it in your head
A polynomial can contain variables, constants, coefficients, exponents, and
operators.
Un polinomio puede contener variables, constantes, coeficientes, exponentes y operadores.
The area of a triangle is A= 1/2bh. Plugging in the values you know, 30= 1/2*12*h.
Solving for h,
30= 1/2*12*h
30= 6h
h=5
The height of the triangle is 5 units.
Answer:
y = 3
y = 2
y = 1
y = 0
Step-by-step explanation:
Given expression;
y = (-x/3) + 2
Find:
Value of y, if x = -3
Value of y, if x = 0
Value of y, if x = 3
Value of y, if x = 6
Computation:
Value of y, if x = -3
y = (-x/3) + 2
y = (3/3) + 2
y = 3
Value of y, if x = 0
y = (-x/3) + 2
y = (-0/3) + 2
y = 2
Value of y, if x = 3
y = (-x/3) + 2
y = (-3/3) + 2
y = 1
Value of y, if x = 6
y = (-x/3) + 2
y = (-6/3) + 2
y = 0
