Answer:It should be 5/9 as its the only one that is probable,

Step-by-step explanation:

If its not 1/2 its not 9/10 so that automautically declines 2 answers leaving 5/18 and 5/9. And 5/18 is way to little for a 36 to 20 ratio, so that leaves 5/9.

Answer:

Step-by-step explanation:

The coefficient of a variable is always the number before the variable, if there is no number before a variable the coefficient is always 1.

In this case, since the subtraction sign is before the variable, you will need to make the variable positive by making the coefficient of variable y, -1.

In short terms, your answer is -1. :)

Answer:

4 teachers

Step-by-step explanation:

If there is one teacher for every 18 students, you would divide the total number of students on the trip (72) by 18..

72/18= 4

so the answer is 4

Answer:

(a) 8

(b) 4

(c)5

Step-by-step explanation:

We are given multiple parts and we  need to provide the correct answer among the given options, also we need to prove that rest of the answers are wrong.

(a). X + 12 = 20 ( 12,8,20,0)

X= 20 -12

X= 8, so only 8 is the correct answer and rest are wrong.

Proof: lets take other given options into consideration

X= 12

X+12 =12+ 24 which is wrong because X+12 is already given as 20.

similarly,

X=20

X+12 = 20+12 = 36, which is wrong because X+12 is already given as 20.

X= 0

X+12 = 0+12 = 12, which is wrong because X+12 is already given as 20.  

(b). P - 4 = 0 (4,-4,8,0)

P-4 = 0

P= 4, So only 4 will give the correct answer and not the other options.

P= -4 = -4 -4 = -8, which is wrong because P-4 is is already given as 0.

similarly,

P = 8  = 8-4 = 4, which is wrong because P-4 is is already given as 0.

P = 0, 0-4 = -4 , which is wrong because P-4 is is already given as 0.  

(c). 2y - 3 = 7 (0,3,5,7)

       2y = 7 + 3

       2y = 10

          y = 5, only 5 will satisfy this given equation and rest will be wrong,

y = 0

2y-3 = 7

2(0) -  3 = 7

-3 = 7 which is not correct as LHS and RHS must be same.

similarly,

y = 3

2y-3=7

2(3) - 3 =7

6-3 = 7

3=7 which is again wrong.

y = 7

2(7) -3 =7

14-3 = 7

11=7, which is wrong.

Therefore the given options for the correct answers is verified and the wrong answers are given as the proof.

Answer:

500 mg

Step-by-step explanation:

K H D B D C M (Kilo, Hecto, Deka, Base [meters, grams, etc.] Deci, Centi, Milli)

since you're using grams substitute G for B

K H D G D C M

you have 0.5 grams of salt, which will be G for grams. you want to convert it to milligrams, which is M. you will move the decimal over 3 spots in order to get from G to M, therefore you go from 0.5 grams to 500 milligrams. I hope this is helpful!

Answer:

Cubic Trinomial

it has 3 terms so it is Trinomial

and cubic because degree is 3

The name of the polynomial is a biquadratic trinomial. Then the correct option is D.

A polynomial expression is an algebraic expression with variables and coefficients.

The polynomial is given below.

⇒ 7n³ + 10n⁴ + 3n

The number of the terms in the polynomial is 3, then the polynomial is a trinomial.

And the degrees of the polynomial is 4, then the trinomial is a biquadratic trinomial.

Then the correct option is D.

Answer:

7/12, 7/10, 5/6

Step-by-step explanation:

Answer:

7/12, 5/6, 7/10

Step-by-step explanation:

Just change it to decimal point it will be easier

l = 5 + 2w.

P = 88 cm.

P = 2 ( l + w )

88 cm = 2 ( (5 + 2w) + w)

88 cm = 2 (5 + 3w)

88 cm cm = 10 + 6w

88 cm cm - 10 = 6w

78 cm = 6w

78 cm : 6 = w

13 cm = w

The width is 13 cm.
