Maria was playing a game with her brother. she said "i'm thinking of a number. when you multiply my number by six and add seven, you get twenty five. what is my number? explain.

3

Step-by-step explanation:

Let x be the number which Maria was thinking of.

Then considering the given statement , we have the following equation:-

To solve the above equation, we first subtract 7 on both the sides , we get

Now, divide 6 on both the sides , we get

Hence, maria'a number is 3.

where is the page?

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
