Answer:

-5.4

Step-by-step explanation:

First let's open parenthesis:

-1.6-3.8. It is -3.8 because if you multiply a positive by a negative, you get a negative. Think of it like this:

+ and + equals +

- and - equals +

- and + equals -

+ and - equals -

Now, this is easy math.

-1.6-3.8=-5.4

-5.4 is your answer.

Write a system of equations to describe the situation below, solve using substitution, and fill in the blanks.Josiah has punch c

love history [14]

Let x be the number of weeks; therefore, the two linear equations are

$\begin{gathered} T=2+7x \\ \text{and} \\ C=11+4x \end{gathered}$

Where T stands for the punches on the tea punch card and C for the punches on the coffee punch card.

Solving by substitution. Set T=C, then

$\begin{gathered} T=C \\ \Rightarrow2+7x=11+4x \\ \Rightarrow3x=9 \\ \Rightarrow x=\frac{9}{3}=3 \\ \Rightarrow x=3 \end{gathered}$

Thus, substitute the value of x=3 into the first equation,

$\begin{gathered} x=3 \\ \Rightarrow T=2+7\cdot3=23 \\ \Rightarrow T=23 \end{gathered}$

Thus, after 3 weeks, Josiah will have the same number of punches on each card, and he will have 23 punches on each card.

In a population of 1000 snails, tests of snail color genes show that 160 snails are AA, 480 are Aa and 360 are aa. What is the f

Kipish [7]

Answer:

Option C.

Step-by-step explanation:

Total population = 1000 snails

AA = 160 snails

Aa = 480 snails

aa = 360 snails

Frequency of each type.

$AA=\dfrac{160}{1000}=0.16$

$Aa=\dfrac{480}{1000}=0.48$

$aa=\dfrac{360}{1000}=0.36$

Now, we get

$A^2=0.16\Rightarrow A=\sqrt{0.16}=0.4$

he frequency of the A allele in this population is 0.4.

Therefore, the correct option is C.

A taxi company charges passengers $2.00 for a ride, no matter how long the ride is, and an additional $0.20 for each mile travel

tiny-mole [99]

The answer will be $2.20. Because they only traveled one mile, which is 20 cents. Also the original cost before they even started driving was $2.00.
