Step 2: Solve for x

Answer:

16n+12

Step-by-step explanation:

If all four sides measure 4n+3, then the perimeter is 4 times the length of each side.  4(4n+3) = 16n + 12 = perimeter

Answer:  

x= 1 - y/2

Step-by-step explanation:

1. Subtract y from both sides. 2x=2−y

2. Divide both sides by 22.

x=\frac{2-y}{2} x= 22−y

3. Simplify  \frac{2-y}{2}

22−y to  1-\frac{y}{2}1−2y.   and there u get ur answer x=1−2y

this is for "2x+y=2" btw hope this helped!

Answer:

the answer is 8-2x

Step-by-step explanation:

Answer:

1. C) 3

2. D) -1

3. D) 7^2 - 8*2 - 16

4. B) 75

5. B) 6^2 + (2 - 8)*sqrt(81)

Step-by-step explanation:

1. (10 - (6-4)^2)/2

= (10 - 2^2)/2

= (10 - 4)/2

= 6/2

= 3

2. PEMDAS states that Multiplication is before Subtraction

8 - (5^2-7)/2

= 8 - (25-7)/2

= 8 - 18/2

= 8 - 9

= -1

3. D) 7^2 - (8*2) - 16

= 49 - 16 - 16

= 49 - 32

= 17

4. 3(2 + 3)^2

= 3(5)^2

= 3(25)

= 75

5. 6^2 + (2 - 8)*sqrt(81)

= 36 + (-6*9)

= 36 - 54

= -18

Question attached

Answer:

130

Step-by-step explanation:

Number of students old donors can be calculated from the Pareto chart by adding number of blood donors on the different bars:

Type 0= 50

Type A= 35

Type B =30

Type AB =15

Therefore 50+35+30+15=130 blood donors

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

All we have to do is plug in the values! 1/2(4)(10+5) will give us the area. Now we simplify!

2(15) = A

30=A

Our answer is B!

Answer: 5n≥25 and if you divide 5 on both sides, n≥5 (I don't know if you are supposed to solve or simply put it in the equation form).

Answer:

Neither

Step-by-step explanation:

Triangles are similar if their angles are the same, and if the sides are changed by a proportional ratio. The angles for FED and ZXY are not the same. Therefore, they are not similar

Answer:

D. Neither

Step-by-step explanation:

Similar triangles are scaled versions of each other. Two triangles that are similar will have congruent angles. Hence, to find a triangle that is similarto ABC, the angles of the other triangles will be congruent to the given angles of ABC. As one can see, no other triangle has congruent angles to ABC, and hence the answer is D, neither of the two triangles are similar to ABC.

Answer:

2x-3y=-4

2x=3y-4

x=(3y-4)/2........1

Answer:

the  height of the pole is 220 centimeters

Step-by-step explanation:

The computation of the height of the pole is shown below

Here we applied the pythagoras theorem

Given that

Hypotenuse = 221 = c

And, base = 21 cm = b

a^2 + b^2 = c^2

So, the height is

= 21^2 cm - 221 cm

= 441 cm - 221 cm

= 220 cm

Hence, the  height of the pole is 220 centimeters

Answer:

a) Speed of the cyclist is (2.75/0.4) = 6.875 miles per hour.

b) It will take (5.5/6.875) = 0.8 hours to travel 5.5 miles at this rate.

Answer:

1/a^8/5 for the first, 9b^8/3 for the second, and 8x^25/7 for the third

Step-by-step explanation:

1) With neg exponents, you can just take it and flip it, and make the exp pos i.e. 1/a^8/5

2) When there is an exponent outside of parenthesis of a number with an exponent, you multiply the exponents together i.e. 9b^8/3

3) The same applies to this as the 2nd, we just multiply to get 8x^25/7
