Answer:
X = -12.54 (I am a Math Class Topper in both 6th Grade an 7th Grade)
Step-by-step explanation:
5 x .27 = 1.35
8x - (3 x .27) = .81
1.35 + 8x - .81 = 7x - 12
- 7x - 7x
----------------------------------
1.35 + X - .81 = -12
+ .81 +.81
---------------------------
1.35 + X = -11.19
-1.35 -1.35
-----------------------
X = -12.54
Answer:
1/2
Step-by-step explanation:
Interchange the x and y and solve for the resulting y.
x = 4y^2 - 2
(x + 2) = 4y^2
(x + 2)/4 = y^2
+/- sqrt(x + 2)/2 = y
The graph of these two is below.
The original is in red
The inverse is in blue and green
Answer: 10 tacos
If Noah could get 4 tacos for $6, that means he got one taco for $1.5. Then you do 15/1.5. This gives you 10.
Have a nice day!!!
