If 3x + 8 = 23, what is the value of x + 4 ?

Answers

Answer:

9

Explanation:

First we solve for x. Subtracting 8 from both sides gives us 3x = 15, therefore x would be 5. Then we plug that into the second question, which gives us 5+4, which is 9.

X is 5
x+4 is the question
5+4= 9
the answer is 9

How can you test a water source to see whether it is acidic or not

Answers

Answer:

The easiest way to test if water is acidic is to use litmus paper. Litmus paper is a paper that contains special dyes that will change color when exposed to acids or bases. In your case, if you dip blue litmus paper into water samples and it turns pink or red, then the water is acidic.

Okay mate

The easiest way to test if water is acidic is to use litmus paper. Litmus paper is a paper that contains special dyes that will change color when exposed to acids or bases. In your case, if you dip blue litmus paper into water samples and it turns pink or red, then the water is acidic.

A line in the xy-plane passes through the points (1,-2) And has a slope of 1/3. Which of the following points lies on the line?

A) (3,-2)
B) (2,-4/3)
C) (0,-2)
D) (-1,-8/3)

Answers

Answer:

D) (-1,-8/3)

Explanation:

To solve this we need the point-slope formula, because we are given a point and a slope.

y-y₁=m(x-x₁)

In this problem, m=1/3 and (x₁, y₁)=(1, -2)

So when we plug these into the formula we have

y- -2 = 1/3(x-1)  (I will rewrite y - -2 as y+2 because subtracting a negative is the same as adding a positive).

y+2 = 1/3(x-1)  

Now we can plug each of the points from the multiple choice into the equation. If one of them works (gives us a true statement), that's our answer.

A) use 3 for x and -2 for y.

-2 + 2 = 1/3 (3-1)

0 = 1/3 (2)

0=  2/3 This is not correct, so A is not the answer.

B) use 2 for x and -4/3 for y

-4/3 + 2 = 1/3 (2-1)

2/3 = 1/3 (1)

2/3 = 1/3 This is not correct, so B is not the answer.

C) Use 0 for x and -2 for y.

-2+2 = 1/3(0-1)

0=1/3(-1)

0=-1/3 This is not correct, so C is not the answer

D) Use -1 for x and -8/3 for y.

-8/3 +2=1/3(-1-1)

-2/3 = 1/3(-2)

-2/3 = -2/3 This is a true statement. Plus, we had already eliminated A, B, and C, so it would have to be D if our calculations were correct.

A bag contains balls that are red, green, or blue. One third of the balls are red, and 2/7 are blue. The number of green balls is eight fewer than the twice the number of blue balls. How many green balls are in the bag?

Answers

Answer:

16 green balls

Explanation:

x = total balls in bag

Red = 1/3x

Blue = 2/7x

Green = -8+2(2/7x)

Since these are balls, the answers have to be whole numbers. The equations representing the different colors contain fractions and have denominators 3 and 7. So the total number of balls, represented by x, needs to be a factor of 3 and 7. So I did a trial and error thing here:

First possible common denominator = 21, which is 3x7

We test that there are 21 balls in the bag. Substituting 21 into the equations for red, blue and green we get:

red =  1/3(21) = 7

blue = 2/7(21) = 6

green = -8+2(2/7)(21) = 4

But if you add up the colors: 7+6+4 = 14 which is < 21

So we test another common denominator

Next possible common denominator = 42, which is 3x7x2

So we test that there are 42 balls in the bag. Substituting 42 into the equations for red, blue and green we get:

red =  1/3(42) = 14

blue = 2/7(42) = 12

green = -8+2(2/7)(42) = 16

If you add up the colors: 14+12+16 = 42

Write your answer in simplest form. 4/9 x 2/3 A railroad runs form city A to city B, a distance of 800km, through mountainous terrain. The present one-way travel time (including time at intermediate yards) is 20 hours, and the rail freight rate is $20 per ton. There is a truck service that competes with the railroad, running over a roughly parallel road for approximately the same distance, at an average speed of 48km per hour and a rate of $30 per ton. A new highway is planned to replace the existing roads; it is expected that most of the traffic will be trucks (auto usage is expected to be negligible). The performance function of the new facility is t_T = t_0 + bV_T, where V_T is the flow in trucks per hour, t_0 = 10 hours, b = 0.08 hour per truck per hour. The railroad's estimate of the demand function is: V_T/V_R = a_0(t_r/t_R)^a_1 (c_T/c_R)^a_2 where t_T and t_R are the trip times (in hours) by truck and rail, respectively, c_T and c_R are the corresponding rates, V_T and V_R are the corresponding flows and a_0, a_1 and a_2 are parameters. The total demand is likely to remain constant at V_TOT = 200 tons per hour. The rail system is utilized at only a fraction of capacity, so its performance function is flat (travel time is constant, independent of volume). If a_0 = 1, a_1 = -1 and a_2 = -2, find the present flows of freight by truck and rail. Make an estimate of the equilibrium flows if the new highway were built. With the new highway built, what would the equilibrium flow be in each of the following two cases: if the railroad dropped its rate to $15 per ton? if truckers were taxed $5 per ton to help pay for the new highway?
