The algebraic expression that represents twice the sum of some number and 3 is?
n + 2(3)
2(n + 3)
2 + n + 3
2n + 3
Answer:
2(n+3)
Step-by-step explanation:
The sum to 3 = n+3
That sum doubled (~twice) = 2(n+3)
Answer:
2(n+3)
Step-by-step explanation:
Let's look at the statement:
'twice the sum of some number and 3'
Twice means 2 multiplied by something.
What is that something? It is the sum of some number and 3.
Let's replace the some number with variable n.
So it becomes the sum of n and 3, which translates to n+3.
So you put the two parts together:
2 multiplied by (n+3), rewritten as 2(n+3).
How many solutions does 7( X -5 ) = X +13
Answer:
x=8 (one solution)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
7(x−5)=x+13
(7)(x)+(7)(−5)=x+13(Distribute)
7x+−35=x+13
7x−35=x+13
Step 2: Subtract x from both sides.
7x−35−x=x+13−x
6x−35=13
Step 3: Add 35 to both sides.
6x−35+35=13+35
6x=48
Step 4: Divide both sides by 6.
x=8
Answer:
x = 8 (one solution)
Step-by-step explanation:
7x - 35 = x + 13
-x -x
6x - 35 = 13
+35 + 35
6x = 48
divided by six on both sides
x = 8

Which of the following is the difference of two squares

4g-16h
16a^2-4y^2
2x^2-4y^2
25m^3+100n^2
Answer:
2nd option
Step-by-step explanation:
A difference of squares has the general form
a² - b²
where the terms on either side of the subtraction ( the difference ) are both perfect squares.
The only one fitting this description is
16a² - 4y²
= (4a)² - (2y)² ← difference of squares
each of the 17 gorillas at the nature preserve eats 45 pounds a food a day. write an expression that models the amount of food all of the gorillas eat in a day. then evaluate the expression to find how much food they eat
Answer:17x 45=765 pounds
Step-by-step explanation:
All you have to do is multiply.
If each gorilla eats 45 pounds then you multiply amount of gorilla by pounds of food , in this case 17x 45

Help PLSS Thanks ………………….
Answer:
3rd option
Step-by-step explanation:
Given z is inversely proportional to (y - 2)² then the equation relating them is
z = [tex]\frac{k}{(y-2)^2}[/tex] ← k is the constant of proportion
To find k use the condition when y = 5, z = 9 , then
9 = [tex]\frac{k}{(5-2)^2}[/tex] = [tex]\frac{k}{3^2}[/tex] = [tex]\frac{k}{9}[/tex] ( multiply both sides by 9 )
81 = k
z = [tex]\frac{81}{(y-2)^2}[/tex] ← equation of proportion

= t+8t+t+9t+5-10+5+4
=19t+4
Suppose y varies jointly as × and z. What is y when × = 2 and z = 3, if y = 20 when × = 4 and z = 3?
Answer:
y = kxz
Step-by-step explanation:
(Find K)
20 = k(4) (3)
20/12 = k
k = 5/3
(Find Y)
y = (5/3)(2)(3)
y = 10

Step-by-step explanation:
Suppose that Juan can choose to get home from work by car or bus.
When he chooses to get home by car, he arrives home after 7 p.m. 14 percent of the time.
When he chooses to get home by bus, he arrives home after 7 p.m. 62 percent of the time.
Because the bus is cheaper, he uses the bus 83 percent of the time.
What is the approximate probability that Juan chose to get home from work by bus, given that he arrived home after 7 p.m.?
Using conditional probability, it is found that there is a 0.9556 = 95.56% probability that Juan chose to get home from work by bus, given that he arrived home after 7 p.m.
Conditional Probability
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening.In this problem:
Event A: Arrived home after 7 p.m.Event B: Got home by bus.The percentages associated with arriving home after 7 p.m. are:
14% of 17%(by car).62% of 83%(by bus).Hence:
[tex]P(A) = 0.14(0.17) + 0.62(0.83) = 0.5384[/tex]
The probability of both arriving home after 7 p.m. and using bus is:
[tex]P(A \cap B) = 0.62(0.83)[/tex]
Hence, the conditional probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.62(0.83)}{0.5384} = 0.9556[/tex]
0.9556 = 95.56% probability that Juan chose to get home from work by bus, given that he arrived home after 7 p.m.
