Arlecino [84]

Answer:

Step-by-step explanation:

Given the information from the question:

$fg - f = f \times g - f$

Next we can use the order of operations to find the value of the expression.

$fg - f = - 6 \times - 1 - ( - 1) \\ = 6 - ( - 1) \\ = 6 + 1 \\ = 7$

Select the option fo “?” That continues the pattern in each question. 3, -6, 12, 4, 20, ?

Elza [17]

Answer:

The sixth number in series is 13.

Step-by-step explanation:

Given series : 3, -6, 12, 4, 20, ?

The pattern followed by the series is:

The first number = 3

Second number = 3 - 9 = - 6

Third number = - 6 + (9 ×2) = -6 + 18 = 12

Fourth number = 12 - 8 = 4

Fifth number = 4 + (8 ×2) = 20

Sixth number = 20 - 7 = 13

Seventh number = 13 + (7 ×2) = 13 + 14 = 27 and so on.

So as per the above pattern, the sixth number in the series is 13.

The recipe for Perfect Purple Water says, "Mix 8 ml of blue water with 3 ml of red water." Jada mixes 24 ml of blue water with 9

cluponka [151]

Answer:Jada will get same shade as Perfect Purple Water

Step-by-step explanation:

STEP 1

To get the right recipe for Perfect purple water, every new mixture must have an equivalent ratio as the ideal mixture

The ideal mixture is given as

8ml blue water and 3 ml red water.

Step 2

Andre mixes 16ml blue water with 9ml red water

$\frac{8ml}{3ml}$ is not equivalent to $\frac{16ml}{9ml}$

Because dividing Andre's mixture by a common value will not give the equivalent ratio of the ideal recipe

$\frac{16ml}{9ml}$ $\frac{/}{/}$ $\frac{3}{3}$ = $\frac{5.3ml}{3ml}$

Jada mixes 24ml blue water with 9ml red water

$\frac{8ml}{3ml}$ is equivalent to $\frac{24ml}{9ml}$

Because dividing Jada's mixture by a common value gives the equivalent ratio of the ideal recipe

$\frac{24ml}{9ml}$ $\frac{/}{/}$ $\frac{3}{3}$ = $\frac{8ml}{3ml}$

This shows that Jada got the right recipe and will get same shade as Perfect Purple Water but in a higher quantity, 3 times the right recipe for Perfect Purple Water
