Answer:

For this case we have two angles given 45 degrees and x degreed and are complementary so then we need to satisfy this property :

45 +x = 90

Since the condition is that the angles are complementary the sum of the angles needs to be 90 degrees.

If we solve for x from the equation above we got:

x = 90-45= 45

So then the measure for x for this case is 45 degrees and the expression required is:

45 +x = 90

Step-by-step explanation:

Answer:

45° + x° = 90°

Step-by-step explanation:

Two angles are complementary if the sum of the angles is equal to 90 degrees. we can also said that if we had two angles A and B and these angles are complementary, the equation that represent this situation is:

A + B = 90°

Then, if a 45°angle is complementary to an angle measures ×°, the equation that represents this situation is:

45° + x° = 90°

Therefore, solving for x°, we get:

45° + x° - 45° = 90° - 45°

x° = 45°

it means that a 45°angle is complementary to an angle measures 45°

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. She also earns a base salary
Mariulka [41]

Answer: her sales last week was $4300.

Step-by-step explanation:

Let x represent her her sales in a week.

Danielle earns a 8.25% commission on everything she sells at the electronics store where she works. This means that the commission she gets if she makes sales of $x is 0.0825x

She also earns a base salary of $675 per week. The expression for the total earnings for a week in which she made sales of $x would be

0.0825x + 675

if her total earnings for last week were $1,029.75, it means that

0.0825x + 675 = 1029.75

0.0825x = 1029.75 - 675

0.0825x = 1029.75 - 675

0.0825x = 354.75

x = 354.75/0.0825

x = $4300

2x=3y+1/2 I have to write this in standard form and slope intercept form
Sav [38]

Answer:

Step-by-step explanation:

2x = 3y + 1/2

standard : Ax + By = C

2x = 3y + 1/2....multiply everything by 2 to get rid of the fractions

4x = 6y + 1 ....subtract 6y from both sides

4x - 6y = 1 <==

slope intercept : y = mx + b

2x = 3y + 1/2....subtract 1/2 from both sides

2x - 1/2 = 3y....divide everything by 3

2/3x - 1/6 = y...rearrange

y = 2/3x - 1/6 <===
