troy's truck has a 30 gallon gas tank and gets an average of 21 miles per gallon.write an equation to represent the amount of gas in troy' s truck after driving a certain number of miles (assuming he starts with a full tank).define your variables.

Answer:

A. 740 - s = 726

Step-by-step explanation:

The equation states: the original number of students, subtracting the number of students that left, represents the number of students now.

Correct option is (A) 740 - s = 726

Given that a high school had 740 students at the start of the year.

However some students left the school. After that, the school had 726 students.

Let 's' be the  the number of students who left the school

Thus as 's' students left the school, there will be deduction of 's' students from the school

Now this deduction 's' would be from the 740 students which were present in the school and the resultant students after deduction is given to be '726'

Thus we can form the mathematical expression as follows,

[tex]740 - s = 726[/tex]

Thus '740 - s = 726' is the requires expression

The inequality that represents the given situation is (8x + 4y [tex]\geq[/tex] 1500) and this can be determined by using the given data.

Given :

The following steps can be used in order to determine the inequality that describes the number of hours you want to work each week to reach your summer goal of at least $1500:

Step 1 - Let the number of hours you babysit for Mrs. Harris be 'x' and the number of hours you babysit for Mrs. Sanchez be 'y'.

Step 2 - So, the inequality that represents the given situation is given below:

8x + 4y [tex]\geq[/tex] 1500

Now, the average per week can be determined by dividing 1500 by 10. So, you have to make $150 per week.

Answer: [tex]59.8^{\circ} F[/tex]

Step-by-step explanation:

Given : Joaquin recorded a temperature of 62°F this morning for science class.

The temperature increased [tex]6\dfrac{1}{2}^{\circ}F[/tex] in the afternoon before decreasing 8.7°F in the evening.

We can write [tex]6\dfrac{1}{2}[/tex] as [tex]6+\dfrac{1}{2}=6+0.5=6.5[/tex]  .

Now According to the question , the temperature at evening will be :-

[tex]62^{\circ}F+6\dfrac{1}{2}^{\circ}F-8.7^{\circ}F\\\\=62^{\circ}F+6.5^{\circ}F-8.7^{\circ}F\\\\=(62+6.5-8.7)^{\circ}\ F=59.8^{\circ}\ F[/tex]

Hence, the evening temperature was [tex]59.8^{\circ} F[/tex] .

The most precise value of the density of the egg will be 1.18 g / mL.

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Weight of the egg = 57 g

Volume = 48.25 mL

Now,

Since, Weight of the egg = 57 g

Volume = 48.25 mL

We know that;

⇒ Density = Mass / Volume

Substitute all the values, we get;

⇒ Density = 57 g / 48.25 mL

                = 1.18 g / mL

Thus, The density of the egg = 1.18 g/mL

To find out if 95 is closer to 64 or 125, we compare the absolute differences. 95 is 31 units away from 64 and 30 units away from 125. Therefore, 95 is closer to 125.

To determine whether 95 is closer to 64 or 125, we need to calculate the absolute differences between 95 and each of the two numbers:

Since 30 is smaller than 31, 95 is closer to 125 by 1 unit.

Answer:

The index fossils are the same geological age.

Step-by-step explanation:

This could happen due to the split of the Earth millions of years ago. The Continental drift theory states that the Earth's continents have moved over geologic time relative to each other. Then, animals who were together at some time were separated by the continents drift.

Answer:

The right answer is C I took the assessment

The solution is:

x = (z - y)/(a - b), represents the formula that could be used to find x, from the expression ax - bx + y = z.

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

here, we have,

given that,

the expression is:

ax - bx + y = z

now, we have to : Solve for x

Subtract y on both sides:                    

ax - bx = z - y

Factor GCF:                                        

x(a - b) = z - y

Isolate x:                                              

x = (z - y)/(a - b)

Hence, The solution is:

x = (z - y)/(a - b), represents the formula that could be used to find x, from the expression ax - bx + y = z.

Let

L--------> the length of the rectangle

W-------> the width of the rectangle

we know that

the perimeter of the rectangle is equal to

[tex]P=2L+2W[/tex]

[tex]P\leq 96\ cm[/tex]

so

[tex](2L+2W)\leq 96[/tex] ---------> equation [tex]1[/tex]

[tex]L=5W[/tex] ---------> equation [tex]2[/tex]
