Answer:
4.5
Step-by-step explanation:
7.3= y + 2.8
Subtract 2.8 from both sides
7.3 = y+ 2.8
-2.8 -2.8
--------------------
y = 4.5
X^8 = ()^2
x^8 = (x^4)^2
x^8 = x^8
inside the parethesis is x^4
hope this helps
Answer:
37.6 units
Step-by-step explanation:
Perimeter = sum of all sides of the triangle
To find the sum, find the distance between each points.
✔️Distance between points (-7, 6) and (5, -4):
(nearest tenth)
✔️Distance between (-7, 6) and (-7, -4):
|6 -(-4)| = 10 units
✔️Distance between (-7, -4) and (5, -4)
|-7 - 5| = 12 units
✔️ Perimeter = 15.6 + 10 + 12 = 37.6 units
Pretty sure it would be 21x^2+16x+17y
The number of blue roses will be 72. Then the number of red roses that she have at first is 84.
<h3>What is the linear system?</h3>
A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Mrs Fernandez has a total of 156 red and blue roses.
After selling the same number of red and blue roses.
She had 1/3 of the number of red roses and 2/9 of the number of blue roses left.
Let x be the number of red rose and y be the number of blue roses.
Then the equation will be
x + y = 156 ...1
2x/3 = 7y/9
6x = 7y ...2
By solving the equations 1 and 2, we have
x = 84 and y = 72
Then the number of red roses that she have at first is 84.
