For what values of x is x + 2x = 24 true?

1 answer:

5 0

I’m sorry. But none of your choices are correct. The correct answer would be 3 and 4. Further more explaining= 3+ 2 times 4 is 24. 2x= 4. That equals 8 and 3 times 8 is 24

Put the line 2x-4y into slope intercept form

Gekata [30.6K]

In order to make a graph, you need an equation.

' 2x - 4y ' is not an equation. Without an equals sign (=)
it's just an expression that stands for a number.

There's nothing in the question that implies a slope,
or an intercept, or even a graph.

Two cyclists start at the same point and travel in opposite directions. One cyclist travels 4 mile per hour slower than the othe

jeyben [28]

Answer:

12 mph and 16 mph

Step-by-step explanation:

distance = speed * time

56 = s * 2 + (s - 4) * 2

56 = 2s + 2s - 8

56 = 4s - 8

64 = 4s

16 = s

s = 16

s - 4 = 12

4= 6/a + 5 solve for x

Scorpion4ik [409]

Answer:

a=-6

4= 6/a + 5

Subtract 5 from each side

4-5= 6/a + 5 -5

-1 = 6/a

Multiply by a on each side

-1*a = 6/a *a

-a =6

Multiply by -1

In a group of 40 people, 35% have never been abroad. Two people are selected at random without replacement and are asked about t

Alisiya [41]

Answer:

$\frac{7}{60}$

Step-by-step explanation:

Given that in a group of 40 people, 35% have never been abroad. Two people are selected at random without replacement and are asked about their past travel experience.

Since the two are drawn without replacement the first trial affects the second trial. In other words, each trial is not independent of the other.

a) Hence this cannot be binomial experiment. The reason is p=probability for each trial is not constant as first draw affect the probability for Ii draw

b) The probability that in a random sample of 2, no one has been abroad

=Prob of selecting both people from the group where no one has been abroad

We have in the group 35% i.e. 14 people never been to abroad

So required probability = Prob of selecting both from 14 people

= $\frac{14C2}{40C2} \\=\frac{14*13}{40*39} \\=\frac{7}{60}$

Need help please: -2 -5/4 x = 13 what does X mean?

Gnom [1K]

Answer:x=-12

Step-by-step explanation:

−2−

x=13

−2+

−5

x=13

−5

x−2=13

Step 2: Add 2 to both sides.

−5

x−2+2=13+2

−5

x=15

Step 3: Multiply both sides by 4/(-5).
