Answer: 0.1x - 16 (c)

Explanation: The perimeter is the sum of all three sides of the triangle. Since the three side are 0.5x + 9, 3x, and (-3.4x) - 25, the sum is as follows:

0.5x + 9 + 3x + (-3.4x) - 25 = 0.1x - 16

Number of Gallons 2 4 x

Travka [436]

Answer:

The value of x is 8 gallon.

Step-by-step explanation:

Given a table showing approximate conversion from gallons to liters.

Number of Gallons 2 4 x

Number of Liters 7.6 15.2 30.4

We are required to find value of x,

Given : 2 gallon is equal to 7.6 liters.

⇒ 1 liter is equal to $\frac{2}{7.6}=0.263$ liters. ........(1)

given, x gallon equal to 30.4 liters.

⇒ 1 liter is equal to $\frac{x}{30.4}$ liters. .........(2)

from (1) and (2),

⇒ $0.263=\frac{x}{30.4}$

Solving for x, we get,

⇒ $0.263 \times 30.4=x$

⇒ $7.9952=x$

Approximately x = 8

Thus, the value of x is 8 gallon.

Use the function below to find F(2) F(x)=1/3•4^x A.)2 B.)4 C.)8/3 D.)16/3

inna [77]

Answer:

Step-by-step explanation:

The function $F(x) = \frac{1}{3}*4^x$ has value F(2) when x = 2 is substituted.

$F(x) = \frac{1}{3}*4^x\\F(2) = \frac{1}{3}*4^2\\F(2) = \frac{1}{3}*16\\F(2) = \frac{16}{3}$

3/7 = /12 How do I find the answer

guajiro [1.7K]

Cross multiply the denominators by the numerators. In other words, 12 times 3 and 7 times x (x, being our missing number).
We end up with 36 and 7x.
Divide both sides by 7.
36/7x = 5.14
x = 5.14
Hope this helps!
