REY [17]

Answer:

See below.

Step-by-step explanation:

1a)

<u>Angles:</u>

  • 48, 90, 90, a.

<u>Add:</u>

  • 48 + 90
  • = 138 + 90
  • = 228

<u>Subtract:</u>

  • 360 - 228
  • = 132.

Angle a: 132.

1b)

To get angle h above 180°, <u>We need to add h + 164:</u>

  • h + 164
  • = 110 + 164
  • = 274.

h = 110.

This is how to get h over 180°.

one number is four times as large as another if the numbers are added together the result is six less than seven times the small
liubo4ka [24]

Answer:

The numbers are 12 and 3.

Step-by-step explanation:

We can solve this problem by working with the information we have and setting up some equations.

We know that one number is four times as large as another. So, let the smaller number be represented by the variable x and the bigger number be represented by 4x, since it is four times as large.

Now, we know that if the numbers are added together, then the result is six less than seven times the smaller number. This can also be represented by the equation 4x + x = 7x - 6.

Let's solve that equation like so:

4x + x = 7x - 6\\5x =  7x - 6\\-2x = -6\\x = 3

So, the smaller number must be 3 (remember that x represented the smaller number). To find the bigger number, all we need to do is multiply 3 by 4, which gives us 12. Therefore, the numbers are 12 and 3.
