USPshnik [31]

Answer:

30 marbles.

Step-by-step explanation:

Let Fatimah,Siti and Noraini has 4x, 5x and 6x marbles.

$\therefore \: 4x + 5x + 6x = 90 \\ \therefore \: 15x = 90 \\ \therefore \: x = \frac{90}{15} \\ \therefore \: x = 6 \\ 5x = 5 \times 6 = 30$

Hence, Siti received 30 marbles.

7(1 - y) = -3(y-2) What is the answer

Fynjy0 [20]

Answer:

$\huge y = \frac{1}{4}$

Step-by-step explanation:

$7(1 - y) = -3(y-2)$

Expand the terms in the bracket

That's

$7 - 7y = - 3y + 6$

Add 3y to both sides of the equation

$7 - 7y + 3y = 3y - 3y + 6 \\ 7 - 4y = 6$

Subtract 7 from both sides by the equation

$7 - 7 - 4y = 6 - 7 \\ - 4y = - 1$

Divide both sides by - 4

$\frac{ - 4y}{ - 4} = \frac{ - 1}{ - 4} \\$

We have the final answer as

$y = \frac{1}{4} \\$

Hope this helps you

Solve for X. 0.8x + 88.2= 300

Luda [366]

Easy peasy, give me a Brainliest if it helps.

0.8x + 88.2 = 300

Subtract 88.2 by both sides to remove it from the equation on the left.

0.8x = 211.8

Now, divide by 0.8 to reverse the problem by both sides. You get 264.75.
