Equation: y= x+50
(Sorry if I’m wrong, I learned this in 6th grade)
Which equation is correct?
75 × 4 = 70 + 5 × 4
75 × 4 = 70 × 4 + 5 × 4
75 × 4 = 700 × 4 + 5 × 4
75 × 4 = 70 × 4 + 5
It takes a man 20 minutes longer to travel from his home to his place of business if he drives at a rate of 30 mph than if he drives at a rate of 40 mph. How many miles is his home from his place of business?
20 minutes = 1/3 hours
let the distance be S
recall that time taken = distance/velocity
so, the time taken when travelling at 30 mph is S/30
and the time taken when travelling at 40 mph is S/40
therefore
S/30 - S/40 = 1/3
multiply through by 120
4S - 3S = 40
S = 40
distance = 40 miles

Which of the following systems has an infinite number of solutions?
A. x+y=1 and x−y=1
B. x+y=1 and x+y=−1
C. x+y=1 and −x−y=−1
D. x+y=1 and x+y=2
Answer:
C. x+y = 1 and -x-y = -1
Step-by-step explanation:
Remember that if a system of equations has an infinite number of solutions, then the resulting equation from using the first step of the elimination method would have no variables and would be true.
1) Let's try canceling out the equations in option C, x+y =-1 and -x-y =-1. Add the two equations together. (Work shown in attached picture.)
2) All of the terms cancel out with each other, leaving only a true statement of 0 = 0. Thus, option C is the answer.

Seraphina says that ΔKLM is a right triangle. Is she correct?
Seraphina is correct. The sum of the squares of the two legs of the triangle is equal to the square of the hypotenuse.
Seraphina is not correct. The sum of the squares of the two legs of the triangle is not equal to the square of the hypotenuse.
Seraphina is correct. In the diagram, side KM looks perpendicular to side ML, so the triangle must be a right triangle.
Seraphina is not correct. The sum of the legs, 12 cm and 16 cm, does not equal the length of the hypotenuse, 19 cm.
Answer:
B. Seraphina is not correct. The sum of the squares of the two legs of the triangle is not equal to the square of the hypotenuse.
Step-by-step explanation:
If KLM is a right triangle, then 12^2+16^2=19^2,
144+256 = 361
400 = 361 false
so, KLM is not a right triangle as the sum of the squares of the two legs are not equal to the square of the hypotenuse.
The sum of the squares of the two legs of the triangle is not equal to the square of the hypotenuse. Seraphina is incorrect.
What is a Pythagoras Theorem?If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:
|AC|^2 = |AB|^2 + |BC|^2
where |AB| = length of line segment AB. (AB and BC are the rest of the two sides of that triangle ABC, AC being the hypotenuse).
Seraphina says that ΔKLM is a right triangle.
Let us check whether triangle ΔKLM is a right triangle or not.
By the Pythagoras theorem, we have
19² = 16² + 12²
361 = 256 + 144
361 ≠ 400
Thus, the triangle is not a right triangle.

Answer
17 1/7
1b)How much time does it take him to complete his morning walk?
9514 1404 393
Answer:
17 minutes 8.6 seconds (17 1/7 min)2 hours 51 minutes 26 seconds (2 h 51 3/7 min)Step-by-step explanation:
The relationship between time, speed, and distance is ...
time = distance/speed
__
a) For 1 km, the time in hours is ...
time = (1 km)/(3.5 km/h) = 1/3.5 h = 2/7 h
In minutes, that is ...
(60 min/h)(2/7 h) = 120/7 min = 17 1/7 min . . . . time for 1 km
__
b) The time for 10 km is 10 times the time for 1 km, so will be ...
(10)(2/7 h) = 20/7 h = 2 6/7 h
In hours and minutes, that is 2 hours and (6/7)(60 min) = 360/7 min = 51 3/7 min.
The time for 10 km is 2 hours 51 3/7 minutes.
Find the equation of a line that contains the points (6, -7) and (8,5). Write the equation in slope-intercept form.
Answer:
y = 6x - 43
Step-by-step explanation:
(6, -7) and (8,5)
m=(y2-y1)/(x2-x1)
m=(5 + 7)/(8 - 6)
m= 12/2
m = 6
y - y1 = m(x - x1)
y + 7 = 6(x - 6)
y + 7 = 6x - 36
y = 6x - 43

Enzel goes online to buy a graphing calculator. He finds a site that currently has a promotion of 15% off on all orders over $50. Enzel decides to buy his graphing calculator, with a price tag of $83, at this site because he knows that he will get the 15% discount when he checks out. Enzel pays 4.5% sales tax on the discounted price and pays a shipping fee of $6.35. What is the total of Enzel’s online purchase?
a.
$80.07
b.
$80.36
c.
$86.74
d.
$93.09
The total price of the graphing calculator is $80.07.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Percentage is usually denoted by the symbol '%'.
Given that,
Original price of the graphing calculator = $83
There is a 15% off on the site on all orders over $50.
Price of the calculator will be 100 - 15 = 85% of the actual price.
Price of the graphing calculator after the discount = 85% × 83
= 0.85 × 83
= $70.55
Sales tax on the discounted price = 4.5%.
Price after adding sales tax = $70.55 + (4.5% × 70.55)
= $73.72475
There is a shipping fee of $6.35.
Total price = $73.72475 + $6.35
= $80.07475
Hence the total price is a. $80.07.

2) A car travels at a speed of 70 kilometers per hour. How far will it travel in 24 minutes?
Answer:
The distance travelled by the car is 28km in 24 minutes
Step-by-step explanation:
The car travels 70km per 1 hour
The car travels per 24 minutes is
V=70km/60minutes=(70/60)km/min
V=1.16km/min=1.16*24/24minutes=28km/24minutes
Answer:
Approximately 28 kilometers
Step-by-step explanation:
You first divide 70 by 60 to get the total number of km it would go in 1 minute. You will get 1.16666667. Next you will multiply it by 24. You will get approximately 28. So it will travel 28 km in 24 min.

Kyle wants to know how far he can travel on a full tank of
gas. Which method and
reasoning can Kyle use to find the distance he can travel in miles?
Answer:
im sure the answer is 371.79
Step-by-step explanation:
Answer:
Unitary method
Total distance = 371.79 miles
Step-by-step explanation:
We are given that Kyle is buying a new car.
The car driven in one gallon of a gas =24.3 miles
The gas tank holds=15.3 gallons
We have to find the method and reasoning can Kyle use to find the distance he can travel in miles.
We have to find the distance travel in 15.3 gallons of a gas
So , we are using unitary method .
Unitary method : When we want to find more than one units with the help of one unit by multiplying
Because we are finding in 15. 3 gallons which is more than one and we are given that in 1 gallon of a gas car travel 24. 3 miles
Total distance =
Hence, the distance Kyle can travel in 15.3 gallons of gas=371.79 miles
