What is the last operation to be performed when finding the value of this expression?

To find out the last operation, we must solve the entire problem.

We are given:

\frac{5+(-8)}{-3+(-9)(-6)}

Let's simplify the signs so they don't clutter our equation.

\frac{5-8}{-3+(-9)(-6)}

We always need to be sure to use PEMDAS. Since there is no expression to solve in parenthesis and no exponents are present, we will move on to multiplication. We can multiply -9 and -6 in the denominator. When we do that, we get:

\frac{5-8}{-3+54}

Next, all you need to do is combine like terms in the numerator and the denominator.

\frac{-3}{51}

Simplify.

-\frac{1}{17}

To answer the question, the last operation to be performed when finding the value would be division.

Entre Celia y Quique suman 14€. Si Celia tuviera 1 €, tendría el doble de dinero que Quique.¿ Cuanto dinero tiene cada uno?
denpristay [2]

Answer:

La cantidad de dinero

Celia tiene = x = 9.33 €

Quique tiene = y = 4.67 €

Step-by-step explanation:

Representemos la cantidad de dinero

Celia tiene = x

Quique tiene = y

Entre Celia y Quique suman 14 €.

x + y = 14

x = 14 - y

Si Celia tuviera 1 euro, tendría el doble de dinero que Quique.

Por lo tanto,

x = 2 años

Nosotros sustituimos

2y + y = 14

3 años = 14

y = 14/3

y = 4.67 €

x = 14 € - y

x = 14 € - 4.67 €

x = 9.33 €

Por lo tanto,

La cantidad de dinero

Celia tiene = x = 9.33 €

Quique tiene = y = 4.67 €

kap26 [50]

Answer:

23

Step-by-step explanation:

The sides of a square are all the same length, so if 3 of them total 48, one of them must be 48/3 = 16.

If the length of the rectangle is 7 longer than the side of the square, it is

... 16 + 7 = 23

erica [24]

Answer:

z=-1.591

Step-by-step explanation:

Null Hypotheses,

H_0 : p=0.8\\H_a: p>0.80

So we use z-test for one population proportion (right-tailed test)

According to this informaton, we defined that

\alpha=0.05

z_c=1.64 (critical value)

So our Rejection region is R={z:z>1.64}

z=\frac{\bar{p}-p_0}{\sqrt{p_0(1-p_0)/n}} = \frac{0.755-0.8}{\sqrt{0.8(1-0.8)/200}}=-1.591

Not rejection.
