10. Peyton wants to get an A in her Chemistry class this semester. Her first 4 tests were a 94.
1 answer:
Answer:
She needs to get 94 in the fifth test.
Step-by-step explanation:
Peyton wants to get an A in her Chemistry class this semester. Her first 4 tests were 94, 83, 88, and 91.
She has to get an average mark of 90 and to do that let us assume, she has to get x in the fifth test.
So, mathematically
⇒ 356 + x = 90 × 5
⇒ 356 + x = 450
⇒ x = 94
Therefore, she needs to get 94 in the fifth test. (Answer)

EXPLANATION:
1.We must locate the points that the exercise gives us in the Cartesian plane.
2.The figure that it gives us must be moved 3 units to the left and then 2 units up.
3.To correctly translate a figure, we must add the units that the exercise indicates and towards the correct direction, if it tells us that to the left is towards the negative axis, then each of the points given in the exercise we will transfer 3 units towards the left and then add each of the points two units up, then we see that the triangle takes new coordinates for the points.
4.The new coordinates for point E are (3,6)
