Answer:
-3 = x
Step-by-step explanation:
4 (2x + 3) = 4x + 24 + 6x – 6
8x + 12 = 10x + 18
12 = 2x + 18
-6 = 2x

Find the values of x and y.
18.
120°=(2x + y)°
(2x - y)°=140°
Answer:
x = 65, y = - 10
Step-by-step explanation:
Given the 2 equations
2x + y = 120 → (1)
2x - y = 140 → (2)
Adding the 2 equations term by term will eliminate y, that is
4x = 260 ( divide both sides by 4 )
x = 65
Substitute x = 65 into either of the 2 equations and evaluate for y
Substituting into (1)
2(65) + y = 120
130 + y = 120 ( subtract 130 from both sides )
y = - 10
Michael's family was traveling to visit prospective colleges
They drove to the closest college that
interested him, took a tour, and then drove to another
college a little farther from home. The graph shown
represents the situation.
Answer:
Step-by-step explanation:
Domain is defined by the input values (x-values) on the graph.
Range is defined by the output values (y-values) on the graph.
From the graph attached,
Domain: [0, 5]
Range: [0, 300]
Maximum point of the graph is (5, 300). It denotes that Michael's family took 5 hours to reach the maximum point which is 300 miles from their home.

C
Answer:
The answer is 36.87°Step-by-step explanation:
Since it's a right angled triangle we can use trigonometric ratios to find the value of B
To find the value of B we use cosine
That's
cos∅ = adjacent / hypotenuse
From the question
adjacent = 4
hypotenuse = 5
We have
[tex] \cos(B) = \frac{4}{5} \\ B = { \cos }^{ - 1} ( \frac{4}{5}) \\ = 36.869897645...[/tex]
We have the final answer as
36.87° to the nearest hundredthHope this helps you
A turtle travels one half of a foot in 4 seconds. How many feet will a turtle travel in 7 seconds?
Answer: 10.5 inches or .875 feet.
Step-by-step explanation:
First calculate the SPEED = Distance /Time. So 1/2 of a foot = 6 inches so distance of 6 inches divided by time of 4 sec = s 1.5 (inches) per sec. So using Distance = speed x time we calculate 1.5in x 7 sec= a distance of 10.5 inches or 10.5 inches divided by 12in that is in a foot = .875 feet.

What is the equation of a line perpendicular to y = -5x + 4 that passes through (-10, 6)?
Answer: y= 1/5 x + 8
Step-by-step explanation:
To get a perpendicular line, take the reciprocal of the original "m" in the equation and reverse the sign.
- 5 becomes +1/5
Then substitute the y and x values from the given coordinate into the new equation and solve for b
y= mx+b
6=1/5 (-10) + b
6 = -2 +b
8 = b rewrite the new equation and substitute 8 for b
y= 1/5 x + 8

The average price of a movie ticket in the United States from 1980 to 2000 can be modeled by the expression, 2.75+0.10x, where x is the number of years since 1980. Which part of the expression corresponds to the cost of movie tickets in 1980?
Answer:
$4.7Step-by-step explanation:
step one:
Let the cost be y
to solve for the cost of a movie ticket, we need to solve the expression
y=2.75+0.10x
step two:
given that x is the number of years between 1980-2000
the number of years is 20years
put x= 20 in the expression for the cost we have
y=2.75+0.10(20)
y=2.7+2
y=$4.7
Зn + 16 = 7n help pls
Answer:
n = 4
Step-by-step explanation:
3n + 16 = 7n
Cancel out the 3n by subtracting it from both sides
16 = 4n
Divide both sides by 4 so you are left with n=
4 = n
Answer:
[tex]n=4[/tex]
Step-by-step explanation:
To start off you need to subtract 3n from both sides. That would leave you with:
[tex]16=4n[/tex]
Next, you need to divide both sides by 4, since this equation is equal to [tex]n*4[/tex] and we only want a single n, not multiple. That would give us the answer:
[tex]4=n[/tex]
