If Lisa paid $175.98 for 2 pair of shoes and 3 pair of jeans. Each pair of shoes cost 24.99. If each pair of jeans cost the same amount, then each pair of jeans cost is $42.

Two or more expressions with an Equal sign is called as Equation.

Given,

Lisa paid $175.98 for 2 pair of shoes and 3 pair of jeans

Each pair of shoes cost 24.99.

Each pair of jeans cost the same amount, we need to find how much did each pair of jeans cost.

As their are two pair of jeans

24.99+24.99=49.988

49.988 is the cost of pair of shoes.

Now let us remove 49.988 from $175.98 to find cost of jeans

175.988-49.988

125.992

$125.992 is the cost of three jeans

Now divide this by three to get cost of each jeans

125.992 which means 126, divide 126 by 3.

126/3=42

Hence, Each pair of jeans cost is $42

Answer:

14

because 6(5)=30 and -2(8)=-16

30-16=14

Answer:

14

Step-by-step explanation:

All we need to do to get the value of 6a-2b is to plug in 5 for the variable "a" (replace a with 5) and plug in 8 for variable "b" (replace b with 8).

Because the variables are right next to the number, that indicates multplication, so the equation is basically saying 6*a-2*b

So let's plug in the numbers for the variables and solve:

6*5-2*8

6*5=30

2*8=16

30-16=14

So our final answer is 14

Answer:

One spool of thread is $2.98

Step-by-step explanation:

Answer:

$ 2.98

Step-by-step explanation:

Total amount spent by Mila equals $50.86

She bought 5 yards of fabric at $8.98 per yard. Hence, the total amount she spent on fabric is 8.98 × 5 = $44.9

It should be noted that since she bought only 2 kinds of things, this mean that Amount spent of fabric + Amount spent on thread = $50.86

Amount spent on thread = $50.86 - Amount spent on fabrics.

Amount spent on thread = $50.86 - $44.9 = $5.96

This is the total amount spent on thread.

But the question asks amount spent on one spool of thread. Since 2 spools would cost $5.96, one spool would cost $5.96 ÷ 2 = $2.98

[tex]m=\frac{5}{2}[/tex]  

If I am wrong its   [tex]m=\frac{-5}{-2}[/tex]

Step-by-step explanation:

Finding the slope of [tex](-4,5)(-8,-5)[/tex] we use the slope formula

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

[tex]m=\frac{5}{2}[/tex]

Simplify the answer if needed

Answer:

Step-by-step explanation:

There are 24 ways how a particle can travel in XYZW space from the origin to the point (4, 3, 5, 4).

The number of ways how a particle can travel in XYZW space from the origin is equal to the total permutations associated to the quantity of coordinates within the generated space. That is to say:

[tex]x = 4! = 4\times 3\times 2 \times 1[/tex]

[tex]x = 24[/tex]

Answer:

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

Step-by-step explanation:

In the easiest explanation, the answer would be [tex]m=\frac{-1}{3}[/tex]

Using [tex]m=\frac{rise}{run}[/tex]  you will go down one point from [tex](-1,-1)[/tex] because rise is -1. From that point, you will go three points to the left that being because run is a positive number. Then you will find yourself being at the second point which is [tex](2,-2)[/tex].

Another explanation is basically using the slope formula

[tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

Answer:

A) -1/3

Step-by-step explanation:

Answer:

The short answer is there isn’t.

Start by writing each of these as an expression:

x * y = 60

x + y = 7

Next, solve each for the same variable; in this case, y:

(x * y) / x = 60 / x

.: y = 60 / x

(x + y) - x = 7 - x

.: y = 7 - x

Next, replace y of the second expression to the first

y = 60 / x & y = 7 - x

.: 7 - x = 60 / x

Now, solve for x:

(7 - x) * x = (60 / x) * x

.: x * 7 - x^2 = 60

This is quadratic, so write it in the form of ax2 + bx + x = 0

(-1)x^2 + (7)x + (-60) = 0

.: a = -1, b = 7, c = -60

Finally solve for b:

x = (-b +- sqrt(b^2 - 4*a*c)) / 2a

.: x = (-7 +- sqrt(7^2 - 4*-1*-60)) / (2 * -1)

.: x = (-7 +- sqrt(49 - 240)) / -2

.: x = (-7 +- sqrt(-191)) / -2

The square root of a negative value is imaginary and thus there’s no real answer to this problem.

Answer:

d

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

x / 2 - 1 = 3

Add 1 to both sides.

x / 2 = 4

Multiply both sides by 2.

x = 8

Now lets put in 8 for x in our original equation:

8 / 2 - 1 = 3

4 - 1 = 3

3 = 3

This is correct, therefore we know x = 8.

<1 = 82.9 degrees

<2 = 7.1 degrees

Step-by-step explanation:

<1 = x

2x = 90 + 75.8

x = 165.8/2

x = 82.9

Step-by-step explanation:

one gallon is 128oz.

1445 gallons are how many Oz?

that applies the same principle as every-day situations like "every guest will eat 2 dumplings. 12 guests are coming, so how many dumplings do I have to prepare ?"

or totally simple : "every child will get one gift. 4 children are coming, so how many gift do I have to prepare ?"

it all works with multiplication. it is the ultimate application for multiplication.

that is why we use "times" in normal language as in mathematical terms. like "it takes 3 screws to mount a leg to a table. and the table needs 4 legs. how many times do I need to fasten a screw to finish one table ?" well, 4 times 3 or 4×3 = 12 times.

and so, the answer to the original question is then I need to take the amount of one gallon 1445 times.

128 × 1445 = 184,960oz

Answer:

x=9

Step-by-step explanation:

a scale drawing means all the sides are multiplied by the same amount. to find this amount, you can divide the larger side by the bigger side by the smaller side.

15/5 = 3

12/4 = 3

therefore the scale factor is 3. to get the value of x, multiply the value of the third side by 3.

3*3=9

x=9

Mathematical operations are used to represent the relationship between variables

The results of the operations are 8 and 254

The operation is given as:

a * b = 4a^2 - b

(a) 2 * 8

This means that:

a = 2

b = 8

So, we have:

2 * 8 = 4 * 2^2 - 8

Evaluate the exponents

2 * 8 = 4 * 4 - 8

Multiply

2 * 8 = 16 - 8

Subtract

2 * 8 = 8

(b) 2 * 8 * 2

In (a), we have:

2 * 8 = 8

So, the operation becomes

2 * 8 * 2 = 8 * 2

This means that:

a = 8

b = 2

So, we have:

8 * 2 = 4 * 8^2 - 2

Evaluate the exponents

8 * 2 = 4 * 64 - 2

Multiply

8 * 2 = 256 - 2

Subtract

8 * 2 = 254

Hence, the results of the operations are 8 and 254
