Answer:

B.  6Fx + 6Gy = 6H

    Qx + Ry = S

Step-by-step explanation:

Equivalent equations can be created many ways. One of the simplest is to multiply both sides of the equation by the same number. In the answer above, the first equation has been multiplied by 6. Nothing has been done to the second equation.

_____

<em>Comments on other choices</em>

A: some terms have been multiplied by 6. This changes the equation(s) so they are no longer equivalent to the ones you started with.

B: the correct choice

C: see A.

D: the first equation has been multiplied by 6, so that is equivalent to the original. The second equation has the sign of one of the terms changed, so it is now a different equation.

zysi [14]

Answer:

the answer is  

Step-by-step explanation:

The proportion of coconut milk in the cocktail is  ml for every 15 ml of orange juice.

Proportion shows the fractional composition of a given quantity or substance.

So that:

orange juice = 15 ml

contents of the orange juice;

apple juice = 25 ml

coconut milk = 10 ml

total              = 35 ml

So that;

the fraction of apple juice in the orange juice =  x 15

                                          =

the fraction of apple juice in the orange juice =  ml

Also,

the fraction of coconut juice in the orange juice =  x 15

                                        =

the fraction of coconut juice in the orange juice =  ml

Therefore, the proportion of the cocktail that is coconut milk is: for every 15 ml of orange juice, then  ml of coconut juice is required.

Hey yall i would really appreciate your help on this plz
Katarina [22]

Answer:

the length of the opposite side (x), is 27.2

Step-by-step explanation:

For the given right triangle problem;

the opposite side of the given angle, opp. = 22

the hypothenuse side,  hypo. = x

given angle of the triangle, θ = 54⁰

The length of the opposite side (x), is calculated as follows;

sin \ \theta = \frac{opp.}{hypo.} \\\\sin (54) = \frac{22}{x} \\\\x = \frac{22}{sin(54)} \\\\x = 27.2

Therefore, the length of the opposite side (x), is 27.2
