Answer:
$47.25
Step-by-step explanation:
Earnings = (rate of pay)(number of hours worked)
Here,
Earnings last weekend = ($8.75/hr)(5.4 hrs) = $47.25
Answer:
f(x) = (x^2 -4) ( x-5)
Here quadratic factor is ( x^2 -4) As x contains power 2
and linear factor is (x-5) as x contains power 1
Answer:
x = 
/13 ≈ 0.48
Step-by-step explanation:
13x² = 3
x² = 3/13
rationalize the denominator
x = /13
The solution of the equation is as follows;
<h3>How to solve equations?</h3>
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
In other words, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The expression can be solved as follows:
b / 27 = - 3
cross multiply
b = -3 × 27
b = - 81
42 = v + 35
subtract 35 from both sides of the equations.
42 - 35 = v + 35 - 35
v = 42 - 35
v = 7
- 128 = 4x
divide both sides of the equations by 4
4x / 4 = - 128 / 4
x = - 32

Por un sistema de ecuaciones, tiene-se que:
- Cada lapiz cuesta 20 ptas.
- Cada boligrafo cuesta 50 ptas.
-------------------------
- Considera-se un sistema de ecuaciones, con cada boligrafo custando x y cada lapiz custando y.
- <u>Boligrafo cuesta 30 mas que un lapiz</u>, o sea,
- <u>8 boligrafos y 15 lapices cuesta 700</u>, o sea,
-------------------------
- Aplicando el <u>primer ecuación en la segunda, </u>tiene-se el cuesto de cada lapiz:
Cada lapiz cuesta 20 ptas.
-------------------------
Por fin, el cuesto de cada boligrafo es dado por:
Cada boligrafo cuesta 50 ptas.
