Answer:
x= -10
y= -43
Step-by-step explanation:
since both of your equations equals y just plug it into each other and than make the equation: 5x+7=4x-3
and than you can just start with the variables OR numbers and then simplify
5x+7=4x-3
5x+10=4x
10= -x
x= -10
so -10 for x
plug it in to one of your 2 equations to get y
5(-10)+7= y
-50+7=y
y= -43

~Direct Variation When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation. In simpler terms, that means if A is always twice as much as B, then they directly vary. If a gallon of milk costs $3, and I buy 1 gallon, the total cost is $3.~

An article claimed that only 38\88, percent of hotel visitors used the alarm clock provided. A hotel manager wanted to see whether that proportion applied to the hotel where she worked, so she took a random sample of 700700700 of the approximately 10{,}00010,00010, comma, 000 visitors to the hotel one month and checked whether they used their room alarm clock. Of the sampled visitors, only 35\55, percent used the alarm clock. Assuming that the article's 38\88, percent claim is also the true proportion for visitors to the hotel, what is the approximate probability that less than 35\55, percent of the sample used the alarm clock
Answer: P(p<0.35) = 0.05
Step-by-step explanation:
Khan told me
The approximate probability that less than 355 of the same used the alarm clock will be equal to 0.0485.
What is Probability?Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.
As per the given information given in the question,
P = 0.38
Q = 1 - P = 1 - 0.38 = 0.62
n = 700 and sample proportion, p = 0.35
Use the formula given below,
z = (p - P)/√(PQ/n)
z = (0.35 - 0.38)/√(0.38 × 0.62)/700
z = -0.03/0.018
z = -1.666
Now,
For P(X < 35%) = P(Z < -1.66)
= P(-∞ < Z < 0) - P(-1.66 < Z < 0)
= 0.5 - 0.4515 = 0.0485

At a gourmet coffee shop. 3 pounds of dark-roast coffee beans cost $56 and 7 pounds of the same coffee cost $112. On the grid below, graph a line that shows how the cost of these coffee
beans varies proportionally with the number of pounds purchased. Use your graph to identify the unit rate for these coffee beans.
PLEASE ITS DUE IN A HOUR
Answer:
In the question, it says that this is a proportional relationship.
A proportional relationship is something like:
y = k*x
So when we have x = 0, we also need to have y = 0.
For the case in the question, this does not happen, so i guess that the actual question is:
"At a gourmet coffee shop. 3.5 pounds of dark-roast coffee beans cost $56 and 7 pounds of the same coffee cost $112."
We can define:
x = amount of coffee
y = price of that coffee
Now we have two pairs:
$56 to get 3.5lb
$112 to get 7lb
Then we have two points:
(3.5lb, $56)
(7lb, $112)
We can draw these two points and then connect them with a line, this line will represent the proportional relationship.
Now we need to look at the value 1 in the x-axis, then draw a vertical line
At the point where this vertical line intersects the graph, we draw a horizontal line, and the value of y is the value at which this horizontal line intersects the y-axis.
(you can see a rough sketch of this in the image below)
The solution is 1lb of coffee costs $16.
When Brandon went bowling, it cost $4.95 per game, plus a one-time fee to rent the shoes. Brandon played 5 games and paid $32. Write and solve a linear equation to find the cost to rent the shoes. Enter just the equation in slope-intercept form on this question.
Use the equation from the previous question to find the cost of renting the shoes.
Answer:
$7.25.
Step-by-step explanation:
Given that, when Brandon went bowling, it cost $ 4.95 per game, plus a one-time fee to rent the shoes, and knowing that Brandon played 5 games and paid $ 32, to find the cost to rent the shoes the following equation must be performed :
4.95 x 5 + X = 32
24.75 + X = 32
X = 32 - 24.75
X = 7.25
Thus, the cost of renting the shoes was $ 7.25.

Answer:
y = -x + 1
Step-by-step explanation:
y=mx+b
m:slope= rise/run, the line goes down 1 and over 1 so it would be -1/1 which is -1
b:y-intercept: the line crosses the y-axis at 1
plug in m=-1 and b=1 into y=mx+b
y=-1x+1
y=-x+1
The product of two consecutive room numbers is 210. Find the room numbers.
Answer:
104.5 and 105.5
Step-by-step explanation:
Unless there are such things are 1/2 room numbers, there is no answer. But algebraically, x + x + 1 = 2x + 1 = 210
2x + 1 = 210
2x = 209
x = 104.5

Here are the ingredients needed to make 8 pancakes
250ml milk
140 g flour
5 g butter
a) Simon makes 4 pancakes.
Answer: To make 4 pancakes, Simon will need 125 ml milk, 70 grams flour, and 2.5 grams of butter.
Step-by-step explanation:
If that is the recipe to make 8 pancakes, and Simon has 4 pancakes, then Simon needs to cut the recipe in half. So we can multiply each ingredient by 1/2.
250 x 1/2 = 125.
140 x 1/2 = 70.
5 x 1/2 = 2.5
In conclusion, to make 4 pancakes, Simon will need 125 ml milk, 70 grams of flour, and 2.5 grams of butter.

Jayden is driving 390 miles to visit the Gateway Arch in St. Louis. He drives at an average rate of 65 miles per hour. Explain how you can find the amount of time it will take her to get to the arch
Using the relation between velocity, distance and time, it is found that it will take her 6 hours to get to the arch.
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
v = d/t.
For this problem, we have that:
She drives 390 miles, hence d = 390.Her velocity is of 65 miles per hour, hence v = 65.We can solve the equation for t to find the time, hence:
65 = 390/t
65t = 390
t = 390/65
t = 6.
It will take her 6 hours to get to the arch.
