Answer:
1. 15%
2. 85%
Step-by-step explanation:
The graph is 100 units,
the shaded part is 15 units,
so it is 15%,
if it is 15% than the unshaded part is 85%.
Answer:
it is two
Step-by-step explanation:
because it is two
Hi there!
So, our two equations are:
2x + 3y = 20 and
-2x + y = 4
We can see that the x's will cancel out because they're the same number, opposite signs. Then we're left with 4y = 24.
Divide 24 by 4, which is 6.
y = 6, then we plug that in to the first equation for y:
2x + 3(6) = 20
2x + 18 = 20
2x = 2
x = 1
So, she made her first mistake when adding the equations, adding 20 and 4, she somehow got 16.
The solution to the system is (1,6).
I hope I helped!
D is 11
2d - 5 = 17 add 5 to both sides
2d = 22 divide by 2
d = 11 answer
