1. The product of five and a number is 15

dedylja [7]

Answer:

Step-by-step explanation:

(1) $5x = 15$

Dividing both sides by $5$ will give us the answer:

$x = 3$

(2) $x + 6 = 16$

Subtracting both sides by $6$ will give us the answer:

$x = 10$

(3) $\frac{27}{x} = 9$

First let's multiply both sides by $x$

$27 = 9x$

Now, let's divide both sides by $9$ to get our answer:

$x = 3$

(4) $6x = 72$

Dividing both sides by $6$ will give us the answer:

$x = 12$

A bag contains purple marbles and blue marbles, 65 in total. The number of purple marbles is 5 more than 3 times the number of b

Marianna [84]

Lets say there are x blue marbles.

Purple marbles = 5 + 3x
Blue marbles = x
Total = 65

5 + 3x + x = 65
5 + 4x = 65
4x = 65 - 5 = 60
x = 60/4 = 15

Blue marbles = 15

65 - 15 = 50

There are 50 purple marbles.
