What is the solution to this equation?
Aleks04 [339]

b) -4

- 8x +4 =36

First, we subtract 4 from 36 to get 32

36-4=32

-8x=32

Since a negative times a negative equals a positive, then the answer has to be negative because 36 is positive.

32 divided by 8 = 4

B) -4

The Murphy family is on a road trip. On the first day, they traveled 30% of their total distance. On the second day, they travel
olga_2 [115]

Answer:

\frac{11}{20}

On the first day, they traveled 30 percents of the total distance. On the second day they traveled one fourth of the total distance. One fourth converted into percentage is 25 percent. Then you add 30 plus 25 because that is the to a

total distance that Murphy's family traveled for 2 days. It will be 55 percents, and you convert 55 percents into fraction will be 55/100, and you simplify it, will be 11/20.

What is the probability of the spinner landing on 2? A spinner is split into 4 equal parts labeled 1, 2, 3, and 4. StartFraction
liubo4ka [24]

Answer:

The probability of the spinner landing on 2 is one fourth.

Step-by-step explanation:

The spinner is split into 4 equal parts labeled 1, 2, 3, 4

The probability of the spinner landing on 2 is given as:

(Possibility of it landing on 2) ÷ (Total possible outcome)

The total possible outcome is 4, because the spinner could land on 1, or 2, or 3, or 4.

It can only land on 2 once, so the possibility of it landing on 2 is 1.

Probability = 1/4

If -3m + 1 &gt; 7, which of the following is a solution set for m?
Papessa [141]

ANSWER

m < -2

EXPLANATION

We want to find the solution set for m in:

-3m+1>7

First, collect like terms:

\begin{gathered} -3m>7-1 \\ -3m>6 \end{gathered}

Now, divide both sides by -3. When you divide an inequality by a negative number, <em>the sign changes direction</em>:

\begin{gathered} \frac{-3m}{-3}>\frac{6}{-3} \\ m

This means that all values of m must be less than -2.

<em>None of the options contains the correct solution set.</em>
