Solve for x
3x - 7 = 2
Answer:
x = 3
Step-by-step explanation:
Add 7 to both the seven and the two and you get 3x = 9. Next, you divide 3 by both sides and get x = 3.

i will mark you as brianilest The school band sold T-shirts to raise money for an upcoming trip. The band sold 400 T-shirts on Saturday and on Sunday, it will sell 30 percent of that amount. Which statements are true about the number of T-shirts that the band will sell on Sunday? check that all apply A. the answer will be less than 400 because 30 is less than 100 B. The answer will be greater than 400 because 300 percent is greater than 100 C. (100)(4)=400 so 30 (4) is the number of T-shirts the band will sell on Sunday. D. The band will sell 430 T-shirts on Sunday or E. The band will sell 120 T-shirts on Sunday.
Answer:
A and E
Step-by-step explanation:
A is correct because if you have less than 100 percent of something then the value will be less than the original value.
E is correct because 30 percent of 400 is 120 so the band will sell 120 t-shirts on Sunday.

[B] x=7
[C] x=8.7
[D] x =5.9
Answer:
the answer is B, x=7

Solve the following:
a) -5/4 [8/7+16/5]
Answer:
-38/7
Step-by-step explanation:
We are given [tex]-\frac{5}{4}(\frac{8}{7}+\frac{16}{5})\\[/tex]. First find the sum of the fractions in the parentheses. The greatest common multiple is 35 so we have [tex]\frac{8}{7}+\frac{16}{5}=\frac{40}{35}+\frac{112}{35}[/tex].
The sum of [tex]\frac{40}{35}+\frac{112}{35}[/tex] is [tex]\frac{152}{35}[/tex].
Now we multiply it by [tex]-\frac{5}{4}[/tex] so we have
[tex]\\-\frac{5}{4} \cdot \frac{112}{35}\\=-\frac{1}{7}\cdot \frac{38}{1}\\=\boxed{-\frac{38}{7}}\\[/tex]
2. The angle of elevation of the top of a vertical
cliff, as seen from a boat 120 m away, is 32°.
The angle of elevation of the top of a flagpole
at the edge of the cliff, as seen from the boat,
is 37º. Find the height of the flagpole.
Answer: 15.44 m
Step-by-step explanation:
We can think this as two triangle rectangles.
In both cases, the adjacent cathetus is 120m.
When the angle is 32°, the opposite cathetus will be the height of the cliff.
When the angle is 37°, the opposite cathetus will be the heigth of the cliff plus the height of the flagpole.
Then we need to compute both of them and calculate the difference.
We can use the trigonometric relation:
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
in this case we have:
Tan(32°) = (height of the cliff)/(120m)
Tan(32°)*120m = height of the cliff = 74.98m
Now we can use the other angle to compute:
Tan(37°) = (heigth of the cliff + heigth of the flagpole)/120m
Tan(37°)*120m = heigth of the cliff + heigth of the flagpole = 90.42m
Then the height of the flagpole will be:
H = 90.42m - 74.98m = 15.44 m

Answer:
C. y = 4/5x + 2
Step-by-step explanation:
y = mx + b
m is the slope and b is the y-intercept
the slope is 4/5, because of rise/run
y-intercept is 2 as the line goes through 2 on the y-axis
Also it's 4/5 not -4/5 because negative means it's going down, the line in this graph is going up hence positive 4/5

Answer: Any positive number less than 16
The diagram shows AD = 16. Applying a dilation with positive scale factor less than 1, will make the figure shrink. Segment AD becomes smaller, so the new AD will be some length less than 16.
For instance, if you use a scale factor 1/2 = 0.5, then AD = 16 turns into A'D' = 16*0.5 = 8

At a local restaurant, 40% of the lunch customers order a hamburger, 70% of the lunch customers order French fries, and 30% of lunch customers order both a hamburger and French fries. If a lunch customer is randomly selected from this restaurant, what is the probability that the customer order fries if we know they ordered a hamburger?
0.40
0.40
0.43
0.75
0.30
Answer:
hola anyone got tacos
Step-by-step explanation:
The probability that a customer orders fries given that the customer orders hamburger is 0.75
To solve this, we make use of the following representations
A represents the event that a lunch customer orders a hamburgerB represents the event that a lunch customer orders a French friesSo, we have:
[tex]P(A) = 40\%[/tex]
[tex]P(B) = 70\%[/tex]
[tex]P(A\ n\ B) = 30\%[/tex]
The probability that a customer orders fries given that the customer orders hamburger is calculated as:
[tex]P(B | A) =\frac{P(A\ n B)}{P(A)}[/tex]
So, we have:
[tex]P(B | A) =\frac{30\%}{40\%}[/tex]
[tex]P(B | A) =0.75[/tex]
Hence, the probability that a customer orders fries given that the customer orders hamburger is 0.75

Answer:
Step-by-step explanation:
Polynomial with a degree of 3 (due to 3 intersection points). Since the end of the graph is approaching positive infinity, we also know the equation of this graph has a positive coefficient.
(I don't know if you're in calculus yet, but...) We also know that there is a local min and local max, as well as inflection points as the graph changes concavity.
This is an example of a polynomial funciton because the graph of a polynomial function is a smooth continuous curve. Also, I had to graph a polynomial function in one of my past assignments, so I know its appearance.

Answer:
the answer is

Step-by-step explanation:
hope it help
The expression of the total amount paid on snacks is 4(1.5d).
What is the expression?The expression is a sentence with multiple variables and constants connected via mathematical operator. An expression cannot have an equal to “=” sign.
It is known that the cost of a snack for 1 friend is 1.5 times the price of the ticket, d. So, the cost of a snack for 1 friend will be 1.5d
Multiply the cost of snacks for 1 friend by 4, to determine the total cost spent by 4 friends on snacks.
4(1.5d)
Thus, the expression for the total amount spent on snacks will be 4(1.5d).
