Answer:
x=6
Step-by-step explanation:
Given: 4(x+4)+2x=52
Distribute.
4x + 16 + 2x = 52.
Simplify.
6x + 16 = 52.
Subtract 16 on both sides to isolate out the variable.
6x = 36
Divide.
x = 6
Answer:
x = 6
Step-by-step explanation:
first we distribute the 4 to the (x + 4) by multiplying 4 times each of those
4x + 16 + 2x = 52
Then, combine like terms:
6x + 16 = 52
then subtract 16 from both sides of your equation
6x = 36
then divide both sides by 6
x = 6

the lengths of the sides of a triangle are 2n, n^2 and n+5 for what value of n do these lengths not make a triangle ?
Answer:
Step-by-step explanation:
Try n = 2
2n = 4
n^2 = 4
n+5 = 7 That works. It will make a triangle since the 2 smallest numbers are bigger than 7
Try n = 3
2n = 6
n^2 = 9
n + 5 = 8 That works. Same reason as above.
n = 4
2n = 8
n^2 = 16
n + 5 = 9 That works. Same reason.
n = 5
2n = 10
n^2 = 25
n+5 = 10 Aha! That doesn't work. the two smaller numbers only = 20.
There are likely many numbers that don't work. I'll try one more
n = 6
2n = 12
n + 5 = 11
n^2 = 36 This won't work either. Same reason as n = 5.

In this function, if the value of r were to increase, would the value represented by P also increase or stay the same? Why? Explain your answer using terms such as "rate of growth" and "initial value" in the context of the coin problem.
Answer:
P will remain the same
Step-by-step explanation:
Given
[tex]V(t) = P(1 + r)^t[/tex] --- Coin value formula [Missing from the question]
Required
What happens to p when r increases
The coin value function is an exponential function which is of the general form:
[tex]y = a(1 + b)^x[/tex]
From the given function: [tex]V(t) = P(1 + r)^t[/tex]
P represents the initial value and r represents the rate
The rate of change (r) and the initial value (P) of a function are both independent, and they do not depend on one another for their values.
An increment or decrement in r will not affect the value of P.
Conclusively, when the rate (r) changes, the initial value (P) will remain the same.

Answer:
A function f : X → Y is said to be one to one (or injective function), if the images of distinct elements of X under f are distinct, i.e., for every x1 , x2 ∈ X, f(x1 ) = f(x2 ) implies x1 = x2 . Otherwise, it is called many to one function.

Answer:
yes x = 16
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, that is
133 = x + 117 ( subtract 117 from both sides )
16 = x

Each time Caroline goes shopping she decides whether or not to buy fruit.
The probability that she does buy fruit is 0.4.
Independently, she then decides whether or not to buy a CD, with a probability of 0.3 that she does buy a CD.
Work out the probability that she buys fruit or buys a CD or both.
Answer: 0.58
Step-by-step explanation:
Step 1 : Caroline buys fruit and buys cd ( buys both) = 0.12 ( 0.4 x 0.3)
Step 2 : Caroline buys fruit and not cd = 0.28 ( 0.4 x 0.7)
Step 3 : Caroline doesn't buy fruit but buys cd = 0.18 ( 0.6 x 0.3 )
STEP 4 (FINAL STEP) : Add all the probabilities ( 0.12 + 0.28 + 0.18)
Answer: 0.58
Step-by-step explanation:
Step 1 : Caroline buys fruit and buys cd ( buys both) = 0.12 ( 0.4 x 0.3)
Step 2 : Caroline buys fruit and not cd = 0.28 ( 0.4 x 0.7)
Step 3 : Caroline doesn't buy fruit but buys cd = 0.18 ( 0.6 x 0.3 )
STEP 4 (FINAL STEP) : Add all the probabilities ( 0.12 + 0.28 + 0.18)

A teacher lives 8 miles from school. She drives a 2015 Chevy Camaro that gets 19 miles per gallon of gas. How much fuel will she need to get TO AND FROM work for the week?
Answer:
Step-by-step explanation:
Technically we cannot solve this without knowing how many days a week that she works.
f=(16mi*d)(gal/19mi)
f=(16/19)d
We would have to assume that she works a certain amount of days. If we assume she works every day
f=7(16/19)=112/19, approximately 5.9 gal
Point p is the interior of angle abc. If angle abc=125deg and angle abp=62deg, what is the angle pbc?
Answer: The angle ∠ PBC is 63°.
Step-by-step explanation:
Given: Point P is in the interior of ∠ABC.
∠ ABC = 125°
∠ABP= 62°
To find : ∠ PBC
Since P is in the interior of ∠ABC.
Then
∠ ABC = ∠ABP + ∠ PBC
⇒ 125°= 62°+ ∠ PBC
⇒ ∠ PBC= 125° - 62°
⇒ ∠ PBC= 63°
Hence, the angle ∠ PBC is 63°.

2/3x - 7 < 9
help please
Answer:
x<24
*the answer will be incorrect if you meant 2/(3x) instead of (2/3)x
Step-by-step explanation:
First, add 7 to both sides of the inequality to get "2/3x<16." Then multiply both sides by 3 to get "2x<48." Finally, divide both sides by 2 to get "x<24"
