Mathematics
1 answer:
gregori [183]3 years ago
3 0

Answer:

3. 102

4. c

Step-by-step explanation:

For number 3:

(c^2 - a) + b becomes (10^2 - 3) + 5

10^2 = 100

100 - 3 + 5 = 102

For number 4:

Usually when you see distributive property, you're multiplying into parentheses. This time you're factoring out.

20c - 8d

It's not a, because that would be 20c + 8d

It's not b, because that would be 20c -32d

It is c, because 4 x 5c = 20 c and 4 x -2d = -8d

It's not d, because that would be 20c- 8cd

Vladimir [108]

Answer:

Each shrub costs $9.75 and the equation will be 12.5 + 6x = 71

Step-by-step explanation:

Given, a customer bought some potting soil for $12.5 and 6 shrubs. All the shrubs were same price. Total expense was $71.00.  

So, the equation will be:

12.5+ 6x = 71.....(i)

Here, x = price of the shrub as all the shrubs are same price.  

Solving the equation number (i),  

6x = 71-12.5

or, 6x = 58.5  

or, x = 58.5/ 6

or, x = 9.75  

So, each shrub will cost $9.75 each.

If m∠CED = 56° and m∠AEB = (7x – 8)° then what is m∠BEC?
fredd [130]

Using the definition of angles on a straight line, the measure of angle BEC is: 62°.

<h3>What are Angles on a Straight Line?</h3>

Angles that lie on a straight line add up to 180 degrees.

Thus, given that EB bisects ∠AEC, therefore:

m∠BEC = 1/2(180 - m∠CED)

Plug in the values

m∠BEC = 1/2(180 - 56)

m∠BEC = 1/2(124)

m∠BEC = 62°

Thus, using the definition of angles on a straight line, the measure of angle BEC is: 62°.
