Answer: 5,090,000= 5,000,000 + 90,000
Step-by-step explanation:
Answer:
x = y²
Step-by-step explanation:
Given
x = 
and y = 
Note that
x = = × = y²
Thus x = y²
Answer:
27 and 16
Step-by-step explanation:
x + y = 43
x - y = 11
You can add up the two equations so the ys are cancelled out.
2x = 54
x = 27
Plug x in to find y.
27 - y = 11
y = 16
Tigers! Have a great day!
For numbers 15-17, we need to remember that two of a triangle's angles are always acute and the third angle will allow us to classify the triangle based on its angles. now that we know this, let's look at #15. the first two angles listed are acute, and the third is an obtuse angle, therefore it is an obtuse triangle. on #16 we have three acute angles, so it is an acute triangle. #17 has two acute angles and a right angle so it is a right triangle.
on numbers 21-23, we need to know that a triangle with all congruent sides is called equilateral, a triangle with two equal sides is isosceles, and a triangle with no equal sides is called scalene. #21 shows two equal sides so it is an isosceles triangle. #22 has three equal sides so it is an equilateral triangle. #23 has no equal sides so it is scalene. hope this helped! :)
