Answer:
x=-7/9, y=4/3. (-7/9, 4/3).
Step-by-step explanation:
6x+2y=-2
3x-2y=-5
-----------------
9x=-7
x=-7/9
6(-7/9)+2y=-2
-42/9+2y=-2
2y=-2-(-42/9)
2y=-2+42/9
2y=-18/9+42/9
2y=24/9
y=(24/9)/2
y=(24/9)(1/2)
y=24/18
y=4/3
Ok so you find the area of the yellow and the red and the area of the yellow you subtract it with the area aid the red that should give you the correct answer
Actually, its not 4b + 5r its 4b +3r because look
step 1. 6b + 4r - (2b + r)
step 2. 6b + 4r - 2b - r
step 3. (6b - 26) + (4r - r)
step 4. 4b + 3r
So the answer is actually 4b + 3r

Answer:
N = 5/6
Step-by-step explanation:
4/5 N= 2/3. Find N (solve for N).
Isolate N. To do this, multiply both sides of the equation by (5/4):
(5/4)(4/5)N= (5/4)(2/3)
becomes N = 10/12, or N = 5/6.
If you are asking for the number of questions correct, then the question is what is 90% of 70.
Multiply 0.9 and 70
0.9 × 70 = 63
Hope this helps!
