Answer:
x=4
Step-by-step explanation:
5x-x=15+1
4x÷4=16÷4
x=4
The solution to the given linear equation with one variable is 4.
The given equation is 5x-1=x+15.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, the equation can be solved as follows
5x-1=x+15
5x-x=15+1
4x=16
x=16/4
x=4
Therefore, the solution to the given equation is 4.

-16 = -5x + x
please help
Answer:
x = 4
Step-by-step explanation:
-16 = -5x + x --> Collect like terms --> -16 = -4x -->
swap the sides of the equation 4x = -16 -->
Divide both sides of the equation by -4 --> x =4

Answer:
52800 feet
that's the answer.
Answer:
The answer is
52800 feetStep-by-step explanation:
To convert a distance from miles to feet we use the conversion
1 mile = 5280 feetFrom the question the value to be converted is 10 miles
We have
if 1 mile = 5280 feet
Then 10 miles = 10 × 5280
We have the final answer as
52800 feetHope this helps you

Answer:
The cost of the stereo system is $256.
Step-by-step explanation:
What we know:
The cost of the stereo system is $320.
Zenaida is getting the stereo system 20% off.
We can set our equation up like this:
Stereo System = 320-320*20%
(to find the cost of the stereo system, we have to subtract 20% of the original price)
1. Multiply 20 by 100 to change 20% into a decimal
20*100=0.2
2. Plug into the equation and solve
320-320*0.2
= 320-64
= 256

Write an algebraic expression for the two verbal expressions: 1. The product of 5 and twice a number x, decreased by the product of 3 and that same number. 2. Twice the sum of a number x, and another number y, increased by the product of the first number squared and 8.
Answer:
7x for the first expression
2x + 2y + 8x^2
Step-by-step explanation:
5(2x) - 3x
= 10x - 3x = 7x
2x + 2y + x^2(8)
= 2x + 2y + 8x^2
A class has 50 students. 20 students are playing basketball and rest are playing volleyball. The percent of the class playing basketball is?
a) 20 percent
b) 40 percent
c) 60 percent
Answer:
60 percent
Step-by-step explanation:
so 50 is half of 100,right? so that means you can just multiply everything by 2 to make it easier. so then there are 100 students and 40 play basket ball. so that means 40 percent play basketball and that only leaves 60 remaining :)

At the local aquarium,one fish tank contained 1,080 clown fish and 60 parrot fish,for a total of 1,140 fish all together. What is the most reduced ratio of total fish to parrot fish
i can’t figure this out
Answer:
B: 2 1/3 > 2 1/6
is the correct answer
A,C, and D are false answers and are incorrect
Answer:
2 1/3 > 2 1/6
Step-by-step explanation:
5/6 < - 1/3
2 < -2 1/2
negative cannot be bigger than positive
1 1/4 > 1 1/3 if you divide them you would get 1.25 > 1.333333, so 1 1/4 not bigger than 1 1/4

Answer: C
Step-by-step explanation:
To find f(g(x)), you plug in g(x) into f(x).
[tex]f(g(x))=\sqrt{(8x-12)+8}[/tex] [combine like terms]
[tex]f(g(x))=\sqrt{8x-4}[/tex] [factor]
[tex]f(g(x))=\sqrt{4(2x-1)}[/tex] [square root of 4]
[tex]f(g(x))=2\sqrt{2x-1}[/tex]
Now, we know that the answer is C.

A class has 30 boys and 20 girls. The average age of
boys is 11 yrs and girls 12 What is the
average age of the whole class."
x = total age of boys
x / 30 = 11yrs
Multiply both sides by 30
x = 330
y = total age of girls
y / 20 = 12
Multiply both sides by 20
y = 240
(240 + 330) / 50 = 11.4 yrs
The average age of the whole class = 11.4 years.
A class has 30 boys and 20 girls.
The average age of boys and girls is 11 and 12 respectively.
To Find:The average age of the whole class.
Solution:Boys = No. of boys × Age
Boys = 30 × 11 = 330
Girls = No. of girls × Age
Girls = 20 × 12 = 240
Average Age = Boys + Girls / Total no. of boys and girls
Average Age = 330 + 240 / 50
Average Age = 570 / 50
Average Age = 11.4
Answer:Average age of of the whole class is 11.4 .
Solve the following equation for d.
T= Gd - N3
Answer: [tex]d=\frac{T+N3}{G}[/tex]
Step-by-step explanation:
To solve for d, we want to use algebraic properties to isolate d.
[tex]T=Gd-N3[/tex] [add both sides by N3]
[tex]T+N3=Gd[/tex] [divide both sides by G]
[tex]\frac{T+N3}{G} =d[/tex]
[tex]d=\frac{T+N3}{G}[/tex]
Now, we know that [tex]d=\frac{T+N3}{G}[/tex].

Write and solve an equation to find the value of 2 Find the measure of
DAE
110°
A
D
(+4)
30
E
Answer:
m<DAE = 80°
Step-by-step explanation:
Given that m<CAB = 110°,
m<DAE = (x + 4)°,
m<EAF = 30°,
m<EAF + m<DAE = m<DAF (angle addition postulate)
30° + (x + 4)° = m<DAF (substitution)
(34 + x)° = m<DAF
<DAF and <CAB are vertically opposite angles. Vertically opposite angles are said to be congruent. Therefore:
m<DAF = m<CAB
(34 + x)° = 110° (substitution)
The equation above can be used to solve for x as follows:
34 + x = 110
x = 110 - 34 (Subtracting 34 from both sides)
x = 76
m<DAE = (x + 4)°
Plug in 76, to replace x
m<DAE = 76 + 4
m<DAE = 80°

Answer:
Perimeter: 42cm
Area: 66cm^2
Step-by-step explanation:
Answer:
P42 cm - P26 cm = 16 cm + 13 cm = P = 26 cm
Step-by-step explanation:
Those are two rectangles. One total and deduct the missing piece.
P=2(l+w)
First: Total 12 by 9 rectangles = P42 cm
Second: Lengths = 12 -5 = 7 and 9-3 = 6 = P=26
Thirs: add the missing lengts! 7 + 6 cm

A boy rolls down a hill on a skateboard. At time = 4 seconds, that boy has rolled 6 meters from the top of the hill. At time = 7 seconds, the boy has rolled to a distance of 30 meters. What is his average speed?
Answer:
His average speed is 4.75 m/s
Step-by-step explanation:
Here, we are interested in calculating the average speed of the boy.
At time t = 4 seconds, total distance traveled = 6 meters
The average speed here is distance/time = 6/4 = 1.5 m/s
Now at time 30 7 seconds , he has rolled 30 meters
What this actually means is that for the next 3 seconds after the initial 4 seconds, he rolled a total distance of 30-6 = 24 meters. Hence, he rolled 24 meters in the next three seconds
So mathematically, his average speed for the second part of the rolling is 24/3 = 8 meters per second
Conclusively therefore , his average speed will be (1.5 + 8)/2 = 9.5/2 = 4.75 meters per second
