A construction crew has repaired 1.37 miles of a highway. The total length of the highway to be repaired is 7.9. How many miles are left to be repaired?
Answer:
Part A: m+1.37=7.9
Part B: 6.53 miles are left to be repaired.
Step-by-step explanation:
Given,
Length of repaired part = 1.37 miles
Total length to be repaired = 7.9 miles
Miles left to be repaired = m
Part A:
Create an equation to show the relationship between the number of miles repaired and the number of miles left to be repaired, m.
Miles left to be repaired + Length of repaired part = Total length to be repaired
m+1.37=7.9
Part B
How many miles are left to be repaired?
Subtracting 1.37 from both sides
6.53 miles are left to be repaired.
Keywords: length, subtraction

Answer:
x=2,1 solving with quadratic formula
Step-by-step explanation:
what is the measure of ABC?
Answer:
Using exterior angle theorem, we can find the answer.
x+45+3x = 6x+5
4x+45 = 6x+5
45 = 2x+5
40 = 2x
x = 20
TO FIND <ABC, WE WILL NEED TO FIRST FIND THE EXTERIOR ANGLE.
6x+5
= 6(20)+5
= 120+5
= 125
m<ABC:
180-125 (REASON: linear pair)

Of the students in Marci's school, 5/9 have a pet. Of the students who have a pet, 12/25 have a dog. What fraction of the students in the school have a dog?
Answer:
4 / 15
Step-by-step explanation:
Of all students ; 5/9 have a pets
Of the 5/9 who have a pet; 12 /25 have a dog
Fraction of the student in the school who have a dog;
12 /25 of fraction with pet
= 12 /25 of 5 /9
= 12 /25 * 5 / 9
= (12 * 5) / (25 * 9)
= 60 / 225
= 4 / 15
—16t^2 + 64t + 3
Please help as soon as possible 33 points if you do it!!
Answer:
51t^3
Step-by-step explanation:
64+3=67
67 +(-16)=51
t^2 +t= t^3
now you just add them up but they cant be combined because one is a number and the other a variable w an exponent so we just get 51t^3

F(x) = (4x–5)/6
Find the Inverse
Answer:
F^-1 (x) = 3x/2+5/4
Step-by-step explanation:
First, replace f(x) with y
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y
Replace y with f−1(x) f − 1 ( x )
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
Hope this helps! Stay Safe!
What is the answer to: two minus a number x is no more than 0
Answer:
x > 2
General Formulas and Concepts:
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Translate
"Two" = 2
"minus" = subtraction
"a number x" = x
"is no more than" = <
"0" = 0
Step 2: Set up inequality
2 - x < 0
Step 3: Solve for x
Subtract 2 on both sides: -x < -2Divide both sides by -1: x > 2Here we see that any value larger than 2 would work as a solution of x.

Write the slope intercept form of the equation of the line through the given point with the given slope through (-2,5),slope-3/2
i need to know where to graph it too
Step-by-step explanation:
y=2x+3
y=3x+3
(Use the elimination method)
y=2x+3(-3) = -6x-9
y=3x+3(2) = 6x+6
(subtract the new equations)
y= -3
(Now find X)
(plug in y in any equation and solve)
y=2x+3
(-3)=2x+3
0= 2x X= 0
or you can just graph the lines go to three on the Y axis put a point go up the y-axis two and over 1 and plot another point.
go to three on the y-axis and plot a point. go up three on the y-axis and over 1

Skylar owns a small business selling bagels. She knows that in the last week 80 customers paid cash, 7 customers used a debit card, and 42 customers used a credit card.
Based on these results, express the probability that the next customer will pay with a credit card as a decimal to the nearest hundredth.
Answer:
The probability that the next customer will pay with credit card is approximately 0.33
Step-by-step explanation:
The given parameters are;
The number of customers that paid cash = 80 customers
The number of customers that used a debit card = 7 customers
The number of customers that used a credit card = 42 customers
The total number of different payments made = 80 + 7 + 42 = 129 payment
Probability = The number of desired outcome/(The number of possible outcome)
The probability that the next customer will pay with credit card = (The number of customers that used a credit card)/(The total number of different payments made)
∴ The probability that the next customer will pay with credit card = 42/129 ≈ 0.33 to the nearest hundredth.

Solve the system of equatior x+2y=14 x-y=13
Answer:
y=7-x/2
y=-13+x
Step-by-step explanation:
Answer:
x=40/3 2/3
Step-by-step explanation:
Use elimination method for this. To do it, Multiply the x-y=13 by 2. It turns into 2x-2y=26. We have this
x+2y=14
2x-2y=26
Add because the signs are different for y each equation.
So 3x=40
x=40/3
14-40/3=2/3
y=2/3
x=40/3

Find the value of c that completes the square
x^2+2x+c
Please help me with how to do this, and show me. Thank you.
Answer:
The value of c that completes the square [tex]x^2+2x+c[/tex] is 1
Step-by-step explanation:
We need to find the value of c that completes the square [tex]x^2+2x+c[/tex]
The formula used will be: [tex]a^2+2ab+b^2=(a+b)^2[/tex]
In the question given the value c can be found by breaking the middle term. we are given 2x while the general formula is 2ab for middle term so,
2(x)(1) = 2x
so, c= 1
Solving:
[tex]x^2+2x+c\\=x^2+2(x)(1)+(1)^2-(1)^2\\=(x+1)^2-1[/tex]
So, the value of c that completes the square [tex]x^2+2x+c[/tex] is 1
