There are 1250 skiers and 2500 snowboarders bought season passes.

The substitution technique is a mathematical approach for solving simultaneous linear equations. The value of one variable with one equation is substituted in the second equation, as the name implies.

The ratio of 1:2 indicates that there is one skier for every two snowboarders.

Let S stand in for the skier.

B should symbolize the snowboarder.

This condition is equivalent to = 1:2 = S:B.

Alternatively, 2S = B.

B - S = 1250

2S - S = 1250

Applying substitution method.

s = 1250

B = 2S = 2(1250) = 2500

B = 2500

There are 1250 skiers and 2500 snowboarders.

Answer:

Answer is x=11

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2(x−8)+11=17

(2)(x)+(2)(−8)+11=17(Distribute)

2x+−16+11=17

(2x)+(−16+11)=17(Combine Like Terms)

2x+−5=17

2x−5=17

Step 2: Add 5 to both sides.

2x−5+5=17+5

2x=22

Step 3: Divide both sides by 2.

2x/2=22/2

x=11

Answer:

Step-by-step explanation:

Considering the cube root of 27, we have that:

a) The correct solution is of 3.

b) The error that Ana likely made is that she considered the cube root as the number that is multiplied by 3 to get a result of 27, not the number that is elevated to three.

The question is that Ana wrote 9 as a solution to the cube root of 27.

The cube root of a number is the number that is elevated by 3 to reach the number, for example:

From the last bullet point, we get the correct answer for item a.

For item b, we have that 9 x 3 = 27, hence the error that Ana likely made is that she considered the cube root as the number that is multiplied by 3 to get a result of 27, not the number that is elevated to three.

The equation for the line through the point (-7,-4) and parallel to the line y = 8x - 4 in point-slope form is y = 8x + 52

The first equation is given as

y = 8x - 4

The slope of the above equation is

m = 8

Parallel lines have equal slope

So, the slope of the other line is

m = 8

The equation is then calculated as

y = m(x - x1) + y1

Where

m = 8

(x1, y1) = (-7, -4)

So, we have

y = 8(x + 7) - 4

Expand

y = 8x + 56 - 4

Evaluate the difference

y = 8x + 52

Hence, the equation for the line through the point (-7,-4) and parallel to the line y = 8x - 4 in point-slope form is y = 8x + 52

Let the Price of a T-shirt is  $x, then the Price of a Sweatshirt is $(x+10)

In The Given Question, 50 T-shirts and 40 Sweatshirts are sold at $1480

Then,

A price is the amount of money that is (often not negatively) exchanged from one party to another in exchange for their goods or services. The cost of production may go by another name in some circumstances. If a product is classified as a "good" in a commercial exchange, its price is most likely to be referred to as such. However, there will be alternative titles for this thing if it is a "service." For instance, the graph at the bottom will display various circumstances.

Answer:

31/4

Step-by-step explanation:

The Mixed Number 7 3/4 can be changed into the improper fraction 31/4.

step 1: The denominator of the improper fraction will be 4, since the denominator of the original fraction is 4.

to find the improper fraction, multiply the denominator of the original fraction (4) by the whole number (7). 4x7=28 then add the numerator of the original fraction: 28+3=31. This tells you the numerator of the improper fraction will be 31.

The improper fraction is 31/4.

Answer:

C. They are similar because corresponding sides are proportional.

Step-by-step explanation:

A and B are not are not how you would find similar triangles, so you can rule those answers out. We can also rule out D since the triangles aren't congruent - we can see they have different lengths. This leaves option C.

Here's how to check:

We'll take the ratio of FD:DE, which is 9:12.

9 ÷ 12 = 0.75

The corresponding sides on the second triange are CA:AB, which is 12:16

12 ÷ 16 = 0.75

9:12 = 12:16

The two traingles are similar & have proportional corresponding sides

Answer:

b: 5 is alone, p, -4p and 5p are in the same group, and 7q is alone
c: 2uv squared and -uv squared are in the same group. Everything else is alone.

Step-by-step explanation:

4 is multiplied by y. Kinda self explanatory.

Even though p doesnt have a number before it, it still does. Variables always have coefficients, and if you can't see it, that means it's one.
uv squared is one of the terms, so any number before it makes it part of the group. Everything else is not similar, so you got your answer.

Answer: D [tex]\frac{23}{13} - \frac{15}{13} i[/tex]

Step-by-step explanation:

Answer:

  a = 4

Step-by-step explanation:

You are given an arithmetic sequence with second term 5.5 and fifth term 10. You want to know the first term.

The 2nd term will have 3 times the common difference added to it to make the 5th term. Then that difference can be found from ...

  5.5 +3d = 10 . . . . using 'd' for the common difference

  3d = 4.5

  d = 1.5

The second term (a2) is obtained by adding the common difference (d) to the first term (a1):

  a2 = a1 +d

  5.5 = a1 + 1.5

  4.0 = a1

The value of 'a' is 4.

__

Additional comment

The 'd' we're using here to represent the common difference is not to be confused with the 'd' in the problem statement that represents the fourth term of the list.

The fact that adjacent list members have the same difference is what tells you this is an arithmetic sequence. In terms of the problem statement, you have ...

  {a, b, c, d, e} = {4, 5.5, 7, 8.5, 10}

Here, we have used the more common notation for elements of an arithmetic sequence.

Last week, the typical amount of money spent by kids in the cafeteria ranged from $2.25 to $3.25.

Equations are logical assertions in mathematics that have two algebraic expressions on either side of an equals (=) sign. The expression on the left and the expression on the right are shown to be equal in reference to one another. LHS = RHS (left hand side = right hand side) appears in all mathematical equations.

A mathematical equation can have many different components, such as coefficients, variables, operators, constants, terms, expressions, and an equal sign. An "=" symbol, as well as terms on both sides, are required when writing an equation.

Given:

Average amount spend = $2.75

Let x be the average dollar amount that students spend.

Then, the equation can be

|x - 2.75| = 0.5

Now, we have two values one is positive and another is negative

x - 2.75 = 0.5 or -(x - 2.75) = 0.5

x = 3.25 or x = 2.25

Hence, Last week, the typical amount of money spent by kids in the cafeteria ranged from $2.25 to $3.25.

For ΔDEF, Where e=52, f=41 and ∠F=48°. Find all the possible ∠E to the nearest degree.

The possible ∠E to the nearest degree is ∠E=70°

Given that,

ΔDEF with e=52 and f=41 sides of the triangle.

Angle ∠F=48°.

We have to find ∠E=?

By using the Law of sine

The relationship between the sides and angles of non-right (oblique) triangles is known as the Law of Sines. It simply states that for all sides and angles of a given triangle, the ratio of the length of a side to the sine of the angle opposite that side is the same.

If triangle ABC are there with sides a, b, and c then Law of sine is

[tex]\frac{a}{SinA} =\frac{b}{SinB} =\frac{c}{SinC}[/tex]

Now, in the given triangle we have e and f sides so we take

[tex]\frac{SinE}{e}=\frac{SinF}{f}\\[/tex]

Substituting the values of e, f and F

We get,

[tex]\frac{SinE}{52}=\frac{Sin48^\circ}{41}\\ SinE=\frac{Sin48^\circ}{41}\times52\\SinE=\frac{52}{41} \times Sin48^\circ\\SinE=1.268\times 0.743\\SinE=0.942\\E=Sin^{-1}(0.942)\\[/tex]

∠E=70°

Therefore, The possible ∠E to the nearest degree ∠E=70°.
