Step-by-step explanation:

Given the expression for the equation representing the prediction of number of trucks as;

2/7 = t/54-t where t is the number of trucks

To get the number of trucks t, we will have to evaluate the expression and solve for t as shown;

Given 2/7 = t/54-t

Cross multiply

2(54-t) = 7t

Open the parenthesis

2(54)-2t = 7t

108-2t = 7t

7t+2t = 108

9t = 108

Divide both sides by 9

9t/9 = 108/9

t = 21

Hence the engineers should have counted 21trucks

Answer:

Answer: the answer is D 25t + 10 hope this helps you

Step-by-step explanation:

All points in the format: (x, 5x + 4) are in the line.

A few examples are: [tex](-2,-6), (-1,-1), (0,4), (1,9), (2,14)[/tex]

--------------------------

The equation of the line is:

[tex]y = 5x + 4[/tex]

This means that the points located on the line have the following format:

[tex](x, y) = (x, 5x + 4)[/tex]

Among the examples:

[tex](-2, 5(-2) + 4) = (-2,-6)[/tex]

[tex](-1, 5(-1) + 4) = (-1,-1)[/tex]

[tex](0, 5(0) + 4) = (0,4)[/tex]

[tex](1, 5(1) + 4) = (1,9)[/tex]

[tex](2, 5(2) + 4) = (2,14)[/tex]

Step-by-step explanation:

Answer:

Step-by-step explanation:

First you have to figure out n. Let's say it's 1, then you would multiply it by 4. That would be 4. Then subtract 32. In this case, then the answer would be - 28.

For this one, first you have to figure out w. Let's make w = 2. Then multiply is by 3 so it would be 6. Then add 66. In this case, it would be 72.

Step-by-step explanation:

Answer:

1. (2,5),(1,3.5),(4,8),(6,11)

2. This is not a proportional relationship (explanation below)

Step-by-step explanation:

For the plotting, if you take some random x values and multiply by 1.5 and add 2 to them.  

This can't be a proportional relationship. A proportional relationship means the x and y values' ratios have to stay the same. However, because 2 is added to 1.5x, the equation is not proportional.

The four x and y values that make the equation true are (0,2), (-1.333,0), (1,3.5), and (1,3.5).

Therefore,

We select several x and y values,

1) Take x=0,

y = 1.5(0) + 2 =2.

The point is (0,2).

2) Take y=0,

0 = 1.5x + 2

x = -2/1.5 = -1.333

The point is (-1.333,0).

3) Take x=1,

y = 1.5(1) + 2 = 3.5

The point is (1,3.5).

4) Take y=1,

1 = 1.5x +2

1.5x = -1

x = -1/1.5 = -0.666.

The point is (-0.666,1).

The four sets of x and y numbers that make the equation true are (0,2), (-1.333,0), (1,3.5), and (0,2).

Answer:

24 23/100

Step-by-step explanation:

I think this is the answer.

9514 1404 393

Answer:

  24 23/100

Step-by-step explanation:

"Twenty-three hundredths," or 23/100, is a fraction that cannot be reduced. The mixed number version is ...

  24 23/100

_____

Additional comment

You start with a denominator that corresponds to the place value of the least-significant digit. Here, that's hundredths, so the fraction you start with is some number of hundredths. Then you reduce the fraction if possible, by canceling all factors of 2 or 5 that you can.

Had it been 23.24, you would start with 23 24/100 and cancel a factor of 4 from numerator and denominator: 23 6/25.

Step-by-step explanation:

[tex]\frac{3^3}{3^-^4}[/tex]

When attempting to solve this, we have to consider the exponent rule of fractional exponents:

[tex]\frac{x^a}{x^b} =x^a^-^b[/tex]

Therefore, our initial problem would become:

[tex]3^3^-^(^-^4^)\\[/tex]

Two negatives become positive:

[tex]3^3^+^4[/tex]

Add:

[tex]3^7[/tex]

[tex]3[/tex] × [tex]3[/tex] × [tex]3[/tex] × [tex]3[/tex] × [tex]3[/tex] × [tex]3[/tex] × [tex]3[/tex]

Answer:

You are now 38 m below base camp.

Step-by-step explanation:

Consider the provided information.

You start hiking at an elevation that is 80 meters below base camp.

Now your initial location is 80 m below base camp, that can be represents as: -80

Now you increase your elevation by 42.

So you go up by 42.

In other words, you get the equation -80+42 = -38.

Since, a negative value is below the base camp, this means that you are now 38 m below base camp.

Step-by-step explanation:

little bear consumes 1/10 jar/min

in 6 minutes , little bear would consume 6 min * 1/10 jar/min = 6/10 jar = 0.6 jar

this means , that in those same 6 minutes papa bear needs to have eaten the remaining 0.4 jar   also it takes 6 min/0.4 jar = 6*10/4 min/jar = 15 min/jar  

The time taken for Papa Bear to eat the jar of honey alone is 15 minutes.

Based on the information given, the little bear will use 1/10 minutes.

In 6 minutes, the little bear will have eaten 0.6 jars

Therefore, the time taken for the papa bear will be:

= 6 minutes / (1 - 0.6)

= 6/0.4

= 15 minutes

Therefore, the correct option is 15 minutes per jar.
