N=90 you have to simplify both sides then isolate the variable :)
Answer:
16
Step-by-step explanation:
Let's call the liters x. We can write 0.15x + 0.4 * 4 = 0.2 (x + 4). When we solve for x we get x = 16 liters.
The answer is c. 48 because angle 3 and 132 equals 180 because they are supplementary angles. So... 180 - 132 = 48 <—- angle 3
Answer:
f(-2) = -30
General Formulas and Concepts:
Pre-Alg
- Order of Operations: BPEMDAS
Step-by-step explanation:
Step 1: Define
f(x) = -3x^2 + 9x
f(-2) is x = -2
Step 2: Solve
1. Substitute: f(-2) = -3(-2)^2 + 9(-2)
2. Evaluate: f(-2) = -3(4) + 9(-2)
3. Multiply: f(-2) = -12 - 18
4. Add: f(-2) = -30
Answer:
t<-25/2
Step-by-step explanation:
move the constant to the right hand side and change the sign
-2t>20+5
add the numbers
-2t>25
20+5=25
divide both sides of the inequality by-2ans flip the inequality sign
t<-25/2
Answer t<-25/2
