Answer/Step-by-step explanation:

Triangle PNM is an equilateral triangle, and angles in an equilateral triangle are all equal to 60.

y=60

Triangle PON is a different triangle, but all angles in a triangle add up to 180.

180-80=100

Because there are 2 angles, you do 100 divided by 2=50

x=50

Answer:

3x + x - 2x + 8 = 3x + x

2. 2 (2x + 4) - 2x = x + 18

3. If x = 5 , evaluate : 2 ( x + 3) + 3x

4. 3 (2x) - 3x + 4= 2x + 5

5. 3x +2x + x = x + 6

6. 2 ( x+ 4) + x = 16

______

   8

multiply by 8 to both sides

x8          x8

2.8 + 2x = 4.8

subtract 2.8 from both sides

-2.8        -2.8

2x = 2

divide by 2 from both sides

/2      /2

x = 1

Answer:

x = 1

Step-by-step explanation:

Step 1: Multiply both sides by 8.

Step 2: Subtract 2.8 from both sides.

Step 3: Divide both sides by 2.

Therefore, x = 1.

Answer:

3.3 seconds

Step-by-step explanation:

v(t) =140t/5t - 6 where v is velocity

The time, t when, v = 44 ft/s

Put v = 44 ft/s in the equation :

44 = 140t / 5t - 6

44(5t - 6) = 140t

220t - 264 = 140t

-264 = 140t - 220t

-264 = - 80t

Divide both sides by 80

264 / 80 = 80t/80

3.3 = t

Hence, automobile will reach a velocity of 44 ft /s after 3.3 seconds

Answer:

2[7x(y – 2) – 6(3y – 4)]

Step-by-step explanation:

If you go down the answer choices and find the solution, this one matches.  Look at picture for better explaining.

The expression will be equal to 2[7x(y-2) - 6 (3y - 4)].

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication and division.

The given expression will be solved as:-

=    2  [  7x(  y-2 ) -  6 ( 3y - 4 ) ].

=   14x ( y - 2 ) - 12 ( 3y - 4 ) ]

=   14xy  -  28x -  36y  -  48

Therefore expression will be equal to 2[7x(y-2) - 6 (3y - 4)].

Explanation:

Rule: If a set has n elements in it, then it will have 2^n subsets.

For example, there are n = 3 elements in the set {a,b,c}. This means there are 2^n = 2^3 = 8 subsets. The eight subsets are listed below.

Subsets 2 through 4 are subsets with exactly 2 elements.  Subsets 5 through 7 are singletons (aka sets with 1 element). The last subset is the empty set which is a subset of any set. You could use the special symbol [tex]\varnothing[/tex] to indicate the empty set.

For more information, check out concepts relating to the power set.

-------------------

The problem is asking what value of n will make 2^n = 64 true.

You could guess-and-check your way to see that 2^n = 64 has the solution n = 6.

Another approach is to follow these steps.

[tex]2^n = 64\\\\2^n = 2^6\\\\n = 6[/tex]

Which is fairly trivial.

Or you can use logarithms to solve for the exponent.

[tex]2^n = 64\\\\\text{Log}\left(2^n\right)=\text{Log}\left(64\right)\\\\n*\text{Log}\left(2\right)=\text{Log}\left(64\right)\\\\n=\frac{\text{Log}\left(64\right)}{\text{Log}\left(2\right)}\\\\n\approx\frac{1.80617997398389} {0.30102999566399} \ \text{ ... using base 10 logs}\\\\n\approx5.99999999999983\\\\[/tex]

Due to rounding error, we don't land exactly on 6 even though we should.

Step-by-step explanation:

Twice the difference of a number and four:  2(x - 4)

three times the sum of the number and 2:  3(x + 2)

2(x - 4) = 3(x + 2)

2x - 8 = 3x + 6

-14 = x

2[(-14) -4] = 2(-18) =-36

3 [(-14) +2] = 3 (-12) = -36

Step-by-step explanation:

we need the greatest or largest common factor (LCF) to find how many bags.

method prime factorization :

beginning with 2 we divide the number as often as possible by the current prime number until there is a remainder. then we use the next higher prime number and do the same.

when we reach 1 as final result, the process ends.

135 ÷ 2 not possible, going to 3

135 ÷ 3 = 45

45 ÷ 3 = 15

15 ÷ 3 = 5

5 ÷ 3 not possible, going to 5

5 ÷ 5 = 1 end

135 = 3×3×3×5

495 ÷ 2 not possible, going to 3

495 ÷ 3 = 165

165 ÷ 3 = 55

55 ÷ 3 not possible, going to 5

55 ÷ 5 = 11

11 ÷ 5 not possible, going to 7

11 ÷ 7 not possible, going to 11

11 ÷ 11 = 1 end

495 = 3×3×5×11

315 ÷ 2 not possible, going to 3

315 ÷ 3 = 105

105 ÷ 3 = 35

35 ÷ 3 = not possible, going to 5

35 ÷ 5 = 7

7 ÷ 5 not possible, going to 7

7 ÷ 7 = 1 end

315 = 3×3×5×7

the LCF is the longest sequence of prime factors the numbers have in common.

so, again, the numbers as prime factors in comparison :

135 = 3×3×3×5

495 = 3×3×5×11

315 = 3×3×5×7

they have in common

3×3 and 5

the LCF = 3×3×5 = 45

so, she can make max. 45 treat bags.

each bag will contain

135/45 = 3 pieces of candy A

495/45 = 11 pieces of candy B

315/45 = 7 pieces of candy C

you notice, how these numbers are exactly the remaining factors of the prime factoring ? it is not a coincidence ...

notice that 45 is the maximum number of treat bags.

following the prime factor combinations she could also create fewer treat bags (but with correspondingly more content).

she could create also

1 or

3 or

5 or

9 or

15

treat bags.

[tex]x=90\\y=-40[/tex]

Step-by-step explanation:

Let's set up a system of equations using the given information.

x+y=50

x-y=130

We can solve this system using elimination. In this case, we can eliminate x by subtracting the two equations.

[tex]x-x+y-(-y)=50-130\\x-x+y+y=50-130[/tex]

[tex]2y=-80[/tex]

Divide both sides by 2.

[tex]y=-40[/tex]

Then, plug -40 in for y to solve for x:

[tex]x+y=50\\x+(-40)=50\\x-40=50\\\text{Add 40 to both sides}\\x=90[/tex]

Therefore..

[tex]x=90\\y=-40[/tex]

Step-by-step explanation:

If the ramp starts closer to the step then the angle would increase.

The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

Given here the height of the step =6 inches and the distance of the ramp from the ground is 5 feet or 59.99 inches

let the angle be θ then  tanθ=6/x where x is the distance from the ramp to the ground thus with the decrease in the distance the value of tanθ increases and hence tan⁻¹(6/x) increases since the arctan function is the inverse of the tangent function.

Hence, If the ramp starts closer to the step then the angle would increase.
