–d + e = –5

Label the ordered pair as (d, e). (4 points)

Select one:

a. (0, 0)

b. (10, –5)

c. (5, 10)

d. (10, 5)

Answers

Answer 1

Answer: We can solve this system of equation by reduction method.
  d+e=15
-d+e=-5
-------------------
2e=10   ⇒e=10/2=5

-(d+e=15)
-d+e=-5
-----------------
-2d=-20   ⇒d=-20/-2=10

therefore: d=10; e=5

Answer: d.(10,5)

43 tens x 3 tens = how many hundreds

Answers

There are 129 hundreds in 43 tens x 3 tens.

What is a place value?

Place value is the value of each digit in a number. It describes the value of every digit in a number depending on its position.

Now it is given that,

43 tens x 3 tens

Therefore we have, 43 tens = 430

and 3 tens = 30

Thus we have,

43 tens x 3 tens = 430 x 30

Multiplying we get,

43 tens x 3 tens = 129,000

⇒ 12,900 = 129 x 100

So, there are 129 hundreds.

Thus, there are 129 hundreds in 43 tens x 3 tens.

Aziza has a triangle with two sides measuring 11 in. and 15 in. She claims that the third side can be any length as long as it is greater than 4 in. Which statement about Aziza’s claim is correct?

Answers

Answer:

Aziza’s claim is incomplete. The third side must be between 4 in. and 26 in.

Step-by-step explanation:

With the Triangle Inequality Theorem, saying that the sum of lengths of any two sides of a triangle is greater than the length of the third side. With this we can develop two inequalities:

11 + 15 > x

26 > x

rewrite this as x < 26

11 + x > 15

x > 15 - 11 Subtract 11 from both sides

x > 4

Therefore, the third side can be anywhere greater than 4 inches and less than and less than 26 inches.

4 < x < 26
