(13x - 15)°
Plsss

. Solve For X,(4x + 21)(13x - 15)Plsss

Answers

Answer 1

Answer:

4

Step-by-step explanation:

use midpoint theorem that also said that the lines are parallel so those angles are same side corresponding angles that are congruent

4x +21 = 13x -15

4x -13x = -15 -21; subtract 13x and 21 from both sides

-9x = -36; divide by -9

x= 4

A certain animal gets food from another animal without killing it. Identify the type of organism.
(A) Saprophyte
(B) Carnivore
(C) Parasite
(D) Autotroph

Answers

Answer:

The correct answer is C. Parasite.

Step-by-step explanation:

Parasitism describes the phenomenon within the animal and plant world that an organism or virus (parasite) misuses a usually considerably larger organism of a different species as a host. The host serves the parasite for food supply (mostly in the form of blood or other body secretions) and in some cases also as a long-term habitat. The host's health is damaged by the parasite, but usually remains alive. The consequences of parasitic infestation range from sting or bite injuries from massive physical complaints to serious infectious diseases and even death in extreme cases. The best known and most widespread human parasites are human lice, mosquitoes and various types of ticks and worms.

Lisa and Marie are both on the track team. During practice, Lisa ran 10 laps around
the track in 18 minutes. Marie ran 8 laps around the track in 14 minutes. Who ran at a
faster rate? If each runner continues at her same pace, how long would it take each
one to run 15 laps?

Answers

Answer:

Marie ran at a faster rate. It takes 27 minutes for Lisa to run 15 laps while it takes Marie 26.25 minutes to run 15 laps.

Step-by-step explanation:

18 ÷ 10 = 1.8 (Lisa's rate)

14 ÷ 8 = 1.75 (Marie's rate)

1.8 x 15 = 27 minutes (How long it takes for Lisa to run 15 laps)

1.75 x 15 = 26.25 (How long it takes for Marie to run 15 laps)

Solve:
3 + 2 + 52 × 6 − 3 =

(3 + 2) + 52 × (6 − 3) =

Answers

Answer:

314 and 161

just use bidmas

1. 3 + 2 + 52 * 6 - 3. *****For both of these questions, we will use BEDMAS = Brackets, Exponents, Division, Multiplication, Addition, Subtraction

3 + 2 + 52 * 6 - 3
= 3 + 2 + 312 - 3
= 314

So, the answer to this question is: 314.

2. (3 + 2) + 52 * (6 - 3)
= 5 + 52 * 3
= 5 + 156
= 161

So, in conclusion, the answer to this problem is: 161.

What is the solution to this system of equations?
X+ 2y = 4
2x-2y = 5
O (3.-53
0
(3.)
no solution
infinitely many solutions

Answers

Answer:

X+2y=4

4+2y=x

2(2+y)=x

2x-2y=5

2(x-y)=5

x-y=5/2

Answer:

(x, y) = (3, 1/2)

Step-by-step explanation:

x + 2y = 4

2x - 2y = 5

There is more than one way to do this. I will do it by substitution.

From the first equation, x + 2y = 4, so x = (-2y) + 4

Now, in the second equation, I will replace x with (-2y + 4)

2(-2y + 4) - 2y = 5

-4y + 8 -2y = 5

-6y + 8 = 5

-6y = -3

6y = 3

y = 3/6

--------------------------------->  y = 1/2, one part of the answer

Now I can go back to the first equation, and relpace 'y' with 1/2

x + 2(1/2) = 4

x + 1 = 4

----------------------------------->  x = 3, the other part of the answer

So now we believe the solution is (x, y) = (3, 1/2)

Now check the answer, back in the original equations!!

------> In the first equation, we would have 3 + 2(1/2) = 4.

                                                                       3 + 1 = 4

                                                                       That is true

-------> In the second equation, we would have 2(3) - 2(1/2) = 5

                                                                                6 - 1 = 5

                                                                          That is true

Our answer is found and checked.

(x, y) = (3, 1/2)
