3x - 20 = 4 PLEASE EXPLAIN HOW YOU GOT THE ANSWER IN STEPS!
Answer:
x = 8
Step-by-step explanation:
3x - 20 = 4
add 20 to both sides
3x - 20 + 20 = 4 + 20
3x = 24
divide both sides by 3
[tex]\frac{3x}{3}[/tex] = [tex]\frac{24}{3}[/tex]
x = 8

The school that Jeremy goes to is selling tickets to a play. On the first day of ticket sales the school sold 8 senior citizen tickets and 9 child tickets for a total of $188. The school took in $70 on the second day by selling 1 senior citizen ticket and 5 child tickets. What is the price of one senior citizen ticket and one child ticket
Answer:
x=$10
y=$12
Step-by-step explanation:
Step one:
given
let senior tickets be x
and child be y
8x+9y=188----1
also on the second day
x+5y=70-------2
the system of equation is
8x+9y=188-----1
x+5y=70---------2
x=70-5y, put this in 1
8(70-5y)+9y=188
560-40y+9y=188
-31y=-372
divide by -31
y=-372/-31
y=$12
put y= 12 in x+5y=70---------2
x+5(12)=70---------2
x+60=70
x=$10

When a quantity is increased or
decreased, what PERCENT describes the
original or starting value?
Answer:
100%
Step-by-step explanation:
The percentage that describes the original value we are calculating from is 100%
This represents the original value that we are working with.
For example if we are to decrease by 10%, it means we are to be left with 90%
If also we are to increase by 10%, it means that we are to be left with 110%

Please anyone help me this is due tomorrow and I don’t know how to do this
Answer:
Number 6 is C, because 40 +80 equals 120
step 2: 180 minus 120 = 60 so Angle C is 60
that is the three interior angles and the only option that has 2 of them is C
I’m struggling. Sorry. Any help is appreciated
Answer:
(8x+13)=(10x-27) being vertically opposite triangles.
Now take the 8 to the next side and minus it by 10x which means 10x-8x, the answer is 2x
Then, do with 27 and 13 also and whatever the answer comes it will be divided by 2, so that is the value of x
Answer:
x = 20
Step-by-step explanation:
The 2 angles are vertical and congruent, thus
10x - 27 = 8x + 13 ( subtract 8x from both sides )
2x - 27 = 13 ( add 27 to both sides )
2x = 40 ( divide both sides by 2 )
x = 20

Give the vertex of each function or inequality
f(x)=|x-1|-1
Answer:
(1,-1)
Step-by-step explanation:
The vertex is the minimum point (in this case). That happens when x - 1 = 0. The reason for that is because the absolute value is going to added to minus 1. The absolute value is always plus.
x - 1 = 0
x - 1+1 = 0 + 1
x = 1
So the minimum point is going to be (1,-1)

You are standing 500 meters from a SpaceXᵗᵐ Rocket that is preparing to take off. The angle of elevation to the top of the rocket is 8o. Find the height of the rocket. Round your answer to the nearest tenth The height of the rocket is meters
Answer:
70.3mStep-by-step explanation:
The set up will be a right angled tringle with angle of elevation of 8°.
The distance you are standing from the rocket (adjacent) = 500m
The height of the rocket (opposite) = x
Using the SOH CAH TOA trig identity;
According to TOA
tan(theta) = opp/adj
tan 8 = x/500
x = 500tan8
x = 500(0.1405)
x = 70.27
x = 70.3m (to the nearest tenth)
Hence the height of the rocket in meters is 70.3m

the volume of a large sphere (of radius R) is twice the volume of a smaller sphere (of radius r). form an equation linking r and R.
Step-by-step explanation:
radius of large sphere is R,
then volume is (4/3)*pie*R³
and
the radius of small sphere is r,
then volume is (4/3)*pie*r³
condition is,
volume of larger sphere is twice of the volume of smaller sphere.
then, (4/3)*pie*R³=2*(4/3)*pie*r³;
R³= 2r³
R=(2^⅓)*r
