solve the equation for y.
xy-7y=49

Answers

Answer 1
We have the equation xy-7y=49.

First, we factor out the common term for "y"
y(x - 7) = 49

Now, divide both sides by x - 7.

y = 49/x-7 <====
Answer 2

The solution of the given equation xy-7y=49 for y is y = 49/(x-7) for all values of x not equal to 7.

To solve the equation xy-7y=49 for y, first we can factor out y from the left side of the equation which gives us y(x-7)=49.

Then we can isolate y by dividing both sides of the equation by (x-7).

This gives us y = 49/(x-7).

This solution assumes that x is not equal to 7 because division by zero is undefined.

Hence, the solution is y = 49/(x-7) for x ≠ 7.

every 2 1/4 hour, 2 13/16 gallons#every 1 hour, x gallons
x=(1 × 2 13/16)/(2 1/4)=(45/16)/(9/4)=(45×4)/(16×9)=180/144=90/72=10/8=5/4= 1 1/4 Gallons

Answer:

[tex]1\frac{1}{4}[/tex]gallon/hour

Step-by-step explanation:

After [tex]2\frac{1}{4}[/tex] hour a chainsaw has used [tex]2\frac{13}{16}[/tex] gallons of fuel.

[tex]2\frac{1}{4}[/tex] hours = [tex]\frac{9}{4}[/tex] hours

[tex]2\frac{13}{16}[/tex] gallons = [tex]\frac{45}{16}[/tex] = 2.8125 gallons

The chainsaw used fuel after [tex]\frac{9}{4}[/tex] hours = [tex]\frac{45}{16}[/tex] gallons

The chainsaw used fuel in 1 hour = [tex]\frac{\frac{45}{16}}{\frac{9}{4}}[/tex]

= [tex]\frac{45}{16}[/tex] ÷ [tex]\frac{9}{4}[/tex]

=  [tex]\frac{45}{16}[/tex] × [tex]\frac{4}{9}[/tex]

= [tex]\frac{180}{144}[/tex]

= [tex]\frac{90}{72}[/tex]

= [tex]\frac{30}{24}[/tex]

A candy manufacturer says on its web site that it wants to reach a 60 : 40 consumer taste preference for new products.What do you think it means

Answers

Final answer:

A candy manufacturer wants to achieve a 60:40 consumer taste preference for new products, meaning they want 60% of consumers to prefer their new products and 40% to prefer other products.

Explanation:

When the candy manufacturer says that it wants to reach a 60:40 consumer taste preference for new products, it means that they aim to have 60% of consumers prefer their new products, while 40% of consumers prefer other products.

For example, if they conducted a taste test and found that out of 100 consumers, 60 preferred their new products and 40 preferred other products, then they have achieved their desired consumer taste preference.

This ratio indicates the target market share the candy manufacturer hopes to capture for its new products.

Final answer:

The candy manufacturer wants 60% of consumers to prefer their new products over others.

Explanation:

The candy manufacturer's statement about wanting to reach a 60:40 consumer taste preference for new products means that they aim to have 60% of consumers prefer their new products over other options, while 40% may still prefer other brands or flavors.

For example, if the company launches a new chocolate bar, their goal is to have 60% of consumers say that they like the new chocolate bar, while 40% may still prefer other chocolate bars or candies.

This ratio indicates the company's desired market share and the level of acceptance they are aiming for in order to consider their new products successful.

Given [tex]f(x)=x+6[/tex]. We can let [tex]y=x+6[/tex]

we can write the ordered pair [tex](x,y)[/tex] or [tex](x,x+6)[/tex] as the ordered pair of the preimage of [tex]f[/tex].

The image function will have the ordered pair [tex](x,-y)[/tex]

Explain how to model the multiplication of 3 and ‒4 on a number line

Answers

First, start at zero. Now, because we are multiplying -4 by 3, we will jump over by 4 to the left  ; 3 times on the number line. We should reach -12, and if we check our work, 3 x -4 = -12.                                            

Final answer:

To model the multiplication of 3 and -4 on a number line, start at zero and make three moves to the left by 4 units, ending up at -12. This demonstrates the rule that multiplying numbers with opposite signs results in a negative product.

Explanation:

To model the multiplication of 3 and -4 on a number line, you can follow these steps:

Start at zero on the number line.

Since you are multipling a positive number by a negative number, you will move in the negative direction (to the left).

Make three moves (corresponding to multiplying by 3), each 4 units to the left. This represents adding -4 three times.

Where you end up on the number line is the product of 3 and -4, which is -12.

This method of multiplication on a number line illustrates the rule that when two numbers multiplied have opposite signs, the answer has a negative sign, such as in the example ( -4) x 3 = -12.

We have to find the correct value of given expression on the number line.

[tex]\frac{11}{6}=1\frac{5}{6}[/tex]

[tex]\frac{5}{6}-\frac{11}{6}[/tex]

[tex]\frac{5-11}{6}=\frac{-6}{6}[/tex]

[tex]\frac{5}{6}-\frac{11}{6}=-1[/tex]

[tex]\frac{5}{6}+(-1\frac{5}{6})[/tex]

When an integer positive and other integer negative and add them .If negative integer is greater and positive integer is small then we go from left to right.

We go [tex]\frac{5}{6}[/tex] step from [tex]-1\frac{5}{6}[/tex]towards right  then we reach at [tex]{-1}[/tex].

The cost of each friend's meal in terms of a is 35/a.  

The cost of each friend's meal when the number of friends is 5 is $7.

The cost of each friend's meal in terms of a is 35/a and the cost of each friend's meal when the number of friends is 5 is $7.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Given the equation,

6 + ax = 41

Where a is the number of people and x is the cost of each friend's meal.

Now,

ax = 41 - 6

ax = 35

x = 35/a

So it will be the cost of each friend's meal in terms of a.

Now,

If the number of friends = 5

Then,

a = 5

So,

x = 35/5 = 7

Hence "The cost of each friend's meal in terms of a is 35/a and the cost of each friend's meal when the number of friends is 5 is $7".

5 times 30 = 150 text messages

Fewer - lower Equal to - same More - higher
The first plan has a fixed cost, $30, and a cost per text message of $0.20.
If you sent t number of text messages, the cost per message is $0.20t.
The total cost of the first plan is

0.2t + 30

The second plan simply costs $60 no matter how many texts you used.
The second plan costs

60

Set the two costs equal to each other to find out how many messages you need to send with the first plan to cost the same as the second plan.

0.2t + 30 = 60

0.2t = 30

t = 150

If you use exactly 150 text messages, the plans cost the same.
If you use fewer than 150 text messages, the first plan costs less.
If you use more than 150 text messages, the firs plan costs more.

Answers

number * 4/5 * reciprocal of 2/5 
number * 4/5 * 5/2 = number * 20/10 = number * 2

So say the number equals x.

Therefore, it would be:

x * 4/5 / 2/5

Division is basically multiplying by the second number flipped, like so:

x * 4/5 * 5/2

Then you could just multiply, saying

x * 20/10

To find Gali's average driving speed, we can divide the distance she can travel by the time it takes her:

140 miles / 3 hours = 46.67 miles per hour (approx).

Now that we know her average driving speed, we can calculate the time it would take her to drive 350 miles from Cleveland to Washington, D.C.
