Given:5y-1/2=7 prove y=3
I am confused on the steps to get 3!
Answer:
y=3/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5y+ −1/2=7
Step 2: Add 1/2 to both sides.
5y+/−1/2+1/2=7+1/2
5y=15/2
Step 3: Divide both sides by 5.
5y/5
=
15/25
y=3/2
The solution of the given equation is y = 3/2.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
We have given the equation as
⇒ 5y - 1/2 = 7
Add 1/2 to both sides in the above equation.
⇒ 5y - 1/2 + 1/2 = 7 + 1/2
⇒ 5y = 15/2
Divide both sides by 5
⇒ y = 15/10
⇒ y = 3/2
Hence, the solution of the given equation is y = 3/2.

What is the slope of the line?
Answer:
y=1x+1
Slope is 1
Step-by-step explanation:
Slope = rise/run.
We go up 1 and run 1. The slope is 1.
Let me double check.
The line passes through the points (-1,0) and (0,1).
m = delta y ÷ delta x
m = (0 - 1)/(-1 - 0)
m = -1/-1
m = 1
Yep. The slope is 1.

4 friends shot free throws for a charity event. Adam scored 8 more points than Cheryl. Laura scored twice as many points as Adam. Tom scored 10 points less than Laura. Together the four friends scored a total of 66 points.
Answer:
c = 6
a = 14
l = 28
t = 18
Step-by-step explanation:
Free throws are usually worth one point each. We can assign variables and use equations to link information between Adam, Cheryl, Laura, and Tom. Then, we can just substitute in our information and solve.
"Adam scored 8 more points than Cheryl"
a = c + 8
"Laura scored twice as many points as Adam"
l = 2a
"Tom scored 10 points less than Laura"
t = l - 10
"Together the four friends scored a total of 66 points"
a + c + l + t = 66
Now we substitute in our variables and solve from there (see attached image)
c = 6
a = 14
l = 28
t = 18
Mr. Myers wants to join a music club. The 1st choice music club charges a $5 sign-up fee and $1 each song. The Superstar music club charges no sign-up fee and charges $3.50 each song. After how many songs will the cost of the music clubs be equal? 1st choice Music Equation: ______ Superstar Music Club Equation: ______ Solution: _____ This was due yesterday and I'm having trouble with this stuff, I'm in advanced math but my teacher moves way too quickly, I would appreciate it if you could help me out.
Answer:
1st choice Music Equation: [tex]\$(x+5)[/tex]
Superstar Music Club Equation: [tex]\$3.50x[/tex]
Solution: 2
Step-by-step explanation:
Given that:
1st choice music club:
Charges for one song = $1
Charges for sign - up = $5
Let the number of songs = [tex]x[/tex]
Total cost = [tex]\$5+\$1\times x = \$(x+5)[/tex]
Superstar music club:
No sign up fee and
Charges for one song = $3.50
Total cost = [tex]\$3.50x[/tex]
Given that, cost of each music club becomes equal:
Putting them same:
[tex]x+5=3.5x\\\Rightarrow 2.5x = 5\\\Rightarrow \bold{x =2}[/tex]
After 2 songs, the cost of both the clubs will become equal.
Blair's garden is four feet shorter than double its width. The perimeter of the garden is 64 feet.
The width of the garden is ___ feet.
The length of the garden is ____ feet.
Answer:
The width of the garden is 12 feet.
The length of the garden is 20 feet.
Step-by-step explanation:
Let l be the length and w be the width
Then according to given statements
[tex]l = 2w-4\ \ \ Eqn\ 1[/tex]
Second equation is:
[tex]2l+2w = 64\ \ \ \ Eqn\ 2[/tex]
Putting l = 2w -4 in equation 2
[tex]2(2w-4)+2w = 64\\4w-8+2w = 64\\6w -8 = 64\\6w = 64+8\\6w = 72\\\frac{6w}{6} = \frac{72}{6}\\w = 12[/tex]
Putting w = 12 in equation 1
[tex]l = 2(12)-4 = 24-4 = 20[/tex]
Hence,
The width of the garden is 12 feet.
The length of the garden is 20 feet.

9) Manny is 7 years older than David. Jeremy is 2 years younger than Manny. Their combined
ages equals 102. How old are Manny, Jeremy and David?
Step-by-step explanation:
answer is done over here step by step
Answer:
Manny: 37 years old
Jeremey: 35 years old
David: 30 years old
Step-by-step explanation:
First, we must divide 102 by 3, since there are 3 people in this scenario.
102 ÷ 3 = 34
We know that 34 is an estimate of each person's age, but there's still more work to do.
Manny is seven years older than David:
30 + 7 = 37
Jeremey is 2 years younger than Manny:
37 - 2 = 35
37 + 35 + 30 = 102
Hope this helps! :)

Deon throws a ball into the air. The height h of the ball, in meters, at time t seconds is modeled by the function h(t)=-5t^2+14t+3 When will the ball hit the ground
Answer:
The time the ball will hit the ground is 1.4s
Step-by-step explanation:
Given;
function of the ball's motion; h(t)= -5t²+ 14t + 3h
The final velocity of the ball, v , is given as;
v = dh/dt
v = -10t + 14
When the ball hits the ground, the final velocity, v = 0
v = -10t + 14
0 = -10t + 14
10t = 14
t = 14 / 10
t = 1.4s
Therefore, the time the ball will hit the ground is 1.4s

Solve x+4/4 = x/x-2
Answer:
After solving the equation [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex] we get x=-2 and x= 4 i.e {-2,4}.
Option B is correct.
Step-by-step explanation:
We need to solve [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex]
Solving:
[tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex]
Cross multiply
[tex](x-2)(x+4)=x*4[/tex]
Multiplying:
[tex]x(x+4)-2(x+4)=4x\\x^2+4x-2x-8=4x\\x^2+2x-8-4x=0\\x^2-2x-8=0[/tex]
Now, we have got quadratic equation [tex]x^2-2x-8=0[/tex]
Solving this quadratic equation using quadratic formula
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\[/tex]
We have a=1, b=-2 and c=-8 Putting values
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-8)}}{2(1)}\\x=\frac{2\pm\sqrt{4+32}}{2}\\x=\frac{2\pm\sqrt{36}}{2}\\x=\frac{2\pm6}{2}\\x=\frac{2+6}{2} \ or \ x=\frac{2-6}{2}\\x=\frac{8}{2} \ or \ x=\frac{-4}{2}\\x=4 \ or \ x=-2[/tex]
So,after solving the equation [tex]\frac{x+4}{4}=\frac{x}{x-2}[/tex] we get x=-2 and x= 4 i.e {-2,4}.
Option B is correct.

The tape diagram represents the ratio of the numbers of planets in two different solar systems. There are 8 planets in Solar System B. How many planets are in Solar System A?
The correct answer is 6 planets
Explanation:
The image presented shows the ratio of planets in solar system A vs those in solar system B. In this way, the general ratio is 3 : 4 or 3 to 4; this means for each 4 four planets in solar system B there are 3 planets in solar system A and vice versa. Now, to find the total of planets in system A if there are 8 planets in system B, follow this process:
8 planets / 4 = 2 planets - This means each of the sections in the diagram represents 2 planets
2 section x 3 = 6 planets as in the solar system A there are 3 sections and each of this represents 2 planets, the total of planets in this system are 6
This result can also be found by converting the ratio to a fraction and multiplying this by the 8 planets
8 planets x [tex]\frac{3}{4} = \frac{24}{4} = 6[/tex]
what is 7x-21=x+3
need step by step
Answer:
[tex]\boxed {x = 4}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]7x - 21 = x + 3[/tex]
-Take [tex]x[/tex] and subtract it from [tex]7x[/tex]:
[tex]7x - 21 - x = x - x + 3[/tex]
[tex]6x - 21 = 3[/tex]
-Add both sides [tex]21[/tex]:
[tex]6x - 21 + 21 = 3 + 21[/tex]
[tex]6x = 24[/tex]
-Divide both sides by [tex]6[/tex]:
[tex]\frac{6x}{6} = \frac{24}{6}[/tex]
[tex]\boxed {x = 4}[/tex]
Thus, the value of [tex]x[/tex] is [tex]4[/tex].
Arianna is buying plants for her garden. She buys 15 flowering plants for $96. Pink flowering plants sell for $8, and purple flowering plants sell for $5. How many pink flowering plants did Arianna buy?
6 pink flowering plants
7 pink flowering plants
8 pink flowering plants
9 pink flowering plants
Answer:
7 pink flowering plantsStep-by-step explanation:
Total number of plants = 15Total cost = $96Cost of pink flowering plant = $8Cost of purple flowering plant = $5Let x and y be the number of plants bought. Then we have equations:
8x + 5y = 96x + y = 15 ⇒ y = 15 - xSubstituting y in the first equation:
8x + 5y = 968x + 5(15 - x) = 968x + 75 - 5x = 963x = 96 - 753x = 21x = 7Correct option is the second one

What is the value of x?
Answer:
x = 50
Step-by-step explanation:
these are vertical angles meaning they are congruent so
[2(x+10)] = (3x-30) then use distributive property
(2x+20) = (3x-30) subtract 2x from both sides
20 = x - 30 add 30 to both sides
x = 50
Answer:
x = 50
Step-by-step explanation:
We know that 2(x+10) = (3x-30) because it is on opposite sides of an "x".
We just set them equal to each other and solve for x!
2(x+10) = 3x - 30
2x + 20 = 3x - 30
20 = x - 30
50 = x
