Answer:

44-2n

Step-by-step explanation:

Hope it helps!

Final answer:

The expression '44 decreased by twice a number' can be represented as 44 - 2n, where n is the unknown number.

Explanation:

The question involves expressing a given mathematical relationship using a variable. Here, the relationship is '44 decreased by twice a number.' To represent this situation with the variable n, we use the expression 44 - 2n. To simplify further, just substitute the variable 'n' with the unknown number. This represents the original number 44 being reduced by two times the value of some unknown number n.

The measure of the third angle is 119 degrees

Step-by-step explanation:

The given is:

We need to find the measure of the third angle in the triangle

The sum of the measures of the interior angles of a triangle is 180°

∵ The measure of an angle = 26°

∵ The measure of another angle = 35°

∵ The some of measures of the 3 angles = 180°

∴ 26° + 35° + x° = 180°, where x is the measure of the 3rd angle

- Add the like terms in the left hand side

∴ 61° + x° = 180°

- Subtract 61 from both sides

∴ x = 119°

The measure of the third angle is 119 degrees

Answer:

Step-by-step explanation:

Answer:

11 + 2x

Step-by-step explanation:

First you will want to separate like variables, so (6, 5) and then (-2x, 4x)

Then you will use the signs to do the math. You can move everything to help visualize the solution easier.

6+5+4x-2x

6+5 = 11

4x-2x = 2x

Because you cannot add or subtract a variable with a non variable, and both numbers are positive you end up with

11 + 2x

The expression 6-2x+5+4x simplifies to 11 + 2x by combining like terms: the constants (6+5=11) and the variables (-2x+4x=2x).

To simplify the expression 6-2x+5+4x, we start by combining like terms. Combining the constant terms (6 and 5) and the variable terms (-2x and 4x), we get:

Constant terms: 6 + 5 = 11

Variable terms: -2x + 4x = 2x

Thus, the simplified expression is 11 + 2x.

Answer: No

Step-by-step explanation: 12 x 4 is 48. 12 x 1/4 is the same as dividing 12 by 4, which gives you 3. 3 is not equal to 48.

The correct statement is that the number 3 is not equal to 48.

I do not agree with him.

Simplification is to make something easier to do or understand and to make something less complicated.

Given

Kim says that multiplying 1/4×12 is the same as dividing 12 x 4

The multiplication of 12×4 = 48.

1/4×12 is the same as dividing 12 by 4, which gives you 3.

Therefore, 3 is not equal to 48.

Answer:

390 miles

Step-by-step explanation:

30 mpg means that he gets 30 miles for every gallon.

If he has 13 gallons means that you multiply 30 by 13.

30 * 13 = 390 miles

Final answer:

Mark can travel 390 miles on 13 gallons of gas, as his car gets 30 miles per gallon and distance is calculated by multiplying fuel efficiency by the number of gallons.

Explanation:

To calculate the distance Mark can travel on 13 gallons of gas, we use the formula: Distance = Fuel Efficiency  imes Number of Gallons.

Mark's car gets 30 miles per gallon. Thus, the distance he can cover on 13 gallons of gas is calculated by multiplying 30 miles/gallon by 13 gallons, which equals 390 miles.

This is a straightforward multiplication problem involving units of fuel efficiency (miles per gallon) and quantity of fuel (gallons).

The solution directly gives us the total number of miles Mark can travel on 13 gallons of gas.

[tex]t = 5[/tex]

Step-by-step explanation:

By the mid-segment theorem of triangles,

[tex]VX= \frac{1}{2} YZ[/tex]

We substitute the expressions in terms of t.

[tex]10t = \frac{1}{2} (t + 95)[/tex]

We multiply through by 2 to get:

[tex]20t = t + 95[/tex]

Subtract t from both sides:

[tex]20t - t = 95[/tex]

[tex]19t = 95[/tex]

Divide both sides by 19:

N = 6 - 2

Step-by-step explanation:

Take each part of the word expression and translate it:

"N"   =>  N        ("N" is a variable that represents a number you don't know)

"is the same as"   =>  =       ("the same" means equals)

"6 reduced by 2"   =>  6 - 2          ("reduced" means use subtraction "-")

Put the sentence back together in the same order.

N = 6 - 2

If you wanted to find "N", you can simplify by doing 6 - 2.

A- The circumference of the tire is about 7.85 feet

B- The tire will rotate about 672 times to travel 1 mile

Step-by-step explanation:

∵ The diameter of a tire is 2.5 ft

∴ d = 2.5 ft

∵ C = π d, where C is the circumference of tire

∴ C = π(2.5) = 7.85398 ft

∴ C ≅ 7.85 feet

A- The circumference of the tire is about 7.85 feet

∵ The tire have to travel 1 mile

∵ 1 mile = 5280 feet

∴ S = 5280 feet

- To find the number of rotation of the tire divide S by C

∵ n =  [tex]\frac{S}{C}[/tex]

$76.5

Step-by-step explanation:

We have been given that inflation from last year to this year was 2% and a pair of designer jeans sold for $75 last year. We are asked to find the price of pair of designer jeans this year.

An inflation of 2% will increase the price of pair of jeans by 2%, so price of pair of jeans this year would be $75 plus 2% of $75.

[tex]\text{Price of pair of jeans this year}=\$75+\$75\times\frac{2}{100}[/tex]

Answer:

a. 157 cm

Step-by-step explanation:

Multiply the diameter times 3.14

3.14 x 50=157 cm.

answer: 157 cm

To find the circumference of a circle given the diameter, multiply the diameter by π (approximately 3.14). Hence, the circumference of the dartboard is approximately 157 cm.

The subject of the question is Mathematics and it covers a topic generally taught in Middle School. When given the diameter of a circle, you can calculate the circumference using the formula C=πd where C is the circumference, π (pi) is about 3.14, and d is the diameter. In this case, the diameter of the dartboard is 50 cm. So, we simply multiply the diameter (50 cm) by π (3.14) to get the circumference. This means the circumference of the dartboard is approximately

Factors of 10 and 14:

10:  1 , 2, 5, 10

14:  1, 2, 7, 14

As you can see, 5 is not a common factor of 10 and 14

The greatest common factor is two

So the answer is false, 5 is not the greatest common factor of 10 and 14

Hope this helps :)

The greatest common factor of 10 and 14 is 2, not 5. The statement is false as 5 is not a factor of 14.

The common factors of 10 and 14 are 1 and 2. Therefore, the GCF of 10 and 14 is 2, not 5. The statement that the greatest common factor of 10 and 14 is 5 is false.

Answer:

Let the number of balcony seats be b

Let the number of gallery tickets be g

Let the number of main floor tickets be m

b + g + m  = 1020

b = 2g

m = b + 225

The number of balcony tickets = 318

The number of gallery tickets = 159

The number of main floor tickets = 543

Step-by-step explanation:

Let the number of balcony seats be b

Let the number of gallery tickets be g

Let the number of main floor tickets be m

i) Therefore we can write b + g + m  = 1020

ii) there were twice as many balcony tickets sold as gallery tickets

   therefore b = 2g      [tex]\Rightarrow[/tex]  g = 0.5b

iii) there were 225 more main floor tickets than balcony tickets

   therefore m = b + 225

iv) using equation ii) and equation iii) in equation i) we can write

     b + g  + m = b + 0.5b + b + 225  = 1020      [tex]\Rightarrow[/tex] 2.5b  = 795     [tex]\Rightarrow[/tex]  b = 318

v) g  = 0.5 b  = 0.5 [tex]\times[/tex] 318 = 159

vi) m = b + 225 = 318 + 225 = 543
