Task:
Engineers are digging a 3200-foot-long tunnel at a constant rate. After 5 months, the engineers still need to dig 1700 feet to finish the project. How much time does it take to complete the tunnel from start to finish?

Will the engineers have enough time if the project was started in December 2020 and the deadline to finish the project was in August 2021? Please explain your answer for yes or no.

Hint:
y=mx+b (slope-intercept form)
x=time
y=distance
b=3200
Start & Finish: ??
Total length=3200ft

Answers

Answer:

318 days or 10.6 months,

No, because the time between august and december is 8 months and it would take 10 to complete the tunnel

Step-by-step explanation:

start by determining the slope:

subtract the remaining distance from the total distance to determine distance so far, then divide by time.

m = (3200 - 1700)/5

m = 1500/5

m = 300

y = mx + b

Plug in to solve for x.

3200 = 300x + 0

3200 = 300x

divide y by m. This is x. (this is known as inverse operation if you didnt know already.)

3200 = 300(10.6_)

Step-by-step explanation:

1)What if you have two equations equal to y? How do you solve for x?
2)If you need to solve for a variable to substitute, what is your first step?
3)What does it mean to substitute for a value?

Answers

Answer:

Step-by-step explanation:

If you have two equations for y, eliminate y by setting these two equations equal to one another.  Solve the resulting equation for x.  Then substitute your x value into one of the equations for y.  Write your solution as (x, y).

2)  If you need to solve for a variable to substitute, what is your first step?  Example:  If you have two equations for y, eliminate y by setting the two equations equal to each other.  This decides for you that you must solve for x.

3)  What does it mean to substitute for a value?  Example:  If you have y = 3x and 2x + y = 17, replace y in the second equation with 3x.  This eliminates y and allows you to solve for x.

Expand the expression 3(5p+1) using the distribution property




PLEASE HELP

Answers

Answer:

15p + 3

Step-by-step explanation:

Multiply 3 by each number in the parentheses and keep the variable

Using the distribution property 3(5p + 1) is  15p + 3.

What are the basic properties of arithmetic laws of operations?

There are three types of basic arithmetic laws of operation.

Commutative law for addition and multiplication states,

a + b = b + a.

a×b = b×a.

Distributive law states,

a(b ± c) = ab ± ac.

Associative law states,

a + (b + c) = (a + b) + c.

Given, An expression 3(5p + 1).

=  3×5p + 3×1.

= 15p + 3.

[tex] \huge \colorbox{red}{y = x + 3}[/tex]

Step-by-step explanation:

to understand thisyou need to know about:linear equationPEMDASgiven:b=3let's solve:

linear equation slope intercept form:

[tex]y = mx + b[/tex]

m is 1 in this question

therefore

substitute the value of m and b

y=x+3

Answer:

y = x + 3

Step-by-step explanation:

The given graph indicates that the y-intercept of this line is 3 (that is, b = 3).  The y-intercept is also represented by (0, 3).  The graph also goes through (-3, 0).  The 'run' is the jump of the x-coordinate from -3 to 0, and thus is 3; the 'rise' is the jump of the y-coordinate from 0 to 3, and is thus 3.  Therefore, the slope of this line, m, is rise/run, which here is m = 3/3, or just 1.

The slope-intercept equation y = mx + b is therefore y = x + 3.

I would suggest you write out your objective before attempting problem solution.  In this case, write out "find the equation of the line shown in this graph, in slope-intercept form."

[tex]3^{-1}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex]\frac{1}{a^{n} }[/tex] ⇔ [tex]a^{-n}[/tex]

Given

[tex]\frac{1}{3}[/tex] = [tex]\frac{1}{3^{1} }[/tex] = [tex]3^{-1}[/tex]

When the exponent is a fraction, you're looking for a root of the base. The root corresponds to the denominator of the fraction. For example, take "125 raised to the 1/3 power," or 125^1/3. The denominator of the fraction is 3, so you're looking for the 3rd root (or cube root) of 125
