Step-by-step explanation:
For volunteers picked up letter from the park Dominic you collect and 15 for your pieces a litter than Sarah Sarah collect the 12 more pieces in piper piper collected 1/4 as many pieces of litter as Vaughn Vaughn has collected nine more pieces of wood or than everyone else combine the X represent the number of pieces of litter Vaughn Collection
So many confusing details. So, I rephrase the question as:
Four volunteers picked up litters from the park.
Dominic collect 15 pieces less than Sarah. Sarah collects 12 more pieces than Piper. Piper collected 1/4 as many pieces of letter as Vaughn. Vaughn has collected nine more pieces of letter than everyone else combined. Let x represent the number of pieces of litter in Vaughn's Collection. Find x
Answer:
[tex]x = 72[/tex]
Step-by-step explanation:
Let:
[tex]D = Dominic;\ \ S = Sarah;\ \ P = Piper;\ \ V = Vaughn[/tex]
From the [rephrased] question, we have:
[tex]D = S - 15[/tex]
[tex]S = 12 + P[/tex]
[tex]P = \frac{1}{4}V[/tex]
[tex]V = 9 + D + S + P[/tex]
Substitute [tex]S = 12 + P[/tex] in [tex]D = S - 15[/tex]
[tex]D = 12 + P - 15[/tex]
[tex]D = P+12 - 15[/tex]
[tex]D = P-3[/tex]
Make V the subject in [tex]P = \frac{1}{4}V[/tex]
[tex]V = 4P[/tex]
Substitute: [tex]V = 4P[/tex], [tex]D = P-3[/tex] and [tex]S = 12 + P[/tex] in [tex]V = 9 + D + S + P[/tex]
[tex]4P= 9 + P - 3 + 12 + P +P[/tex]
Collect like terms
[tex]4P - P -P-P= 9 - 3 + 12[/tex]
[tex]P= 18[/tex]
Substitute [tex]P= 18[/tex] in [tex]S = 12 + P[/tex]
[tex]S = 12 +18[/tex]
[tex]S = 30[/tex]
Substitute [tex]S = 30[/tex] in [tex]D = S - 15[/tex]
[tex]D = 30 - 15[/tex]
[tex]D =15[/tex]
Substitute [tex]D =15[/tex], [tex]S = 30[/tex] and [tex]P= 18[/tex] in [tex]V = 9 + D + S + P[/tex]
[tex]V = 9 + 15 + 30 + 18[/tex]
[tex]V = 72[/tex]
x represents the number collected by Vaughan.
So:
[tex]x = 72[/tex]

Answer:
2.828
Step-by-step explanation:
Pythagoras theorem (a^2)+(b^2)=(c^2)
also written as (base^2)+(altitude^2)=(hypotenuse^2)
Base=2
altitude=2
=Base = 2*2=4
=Altitude = 2*2=4
4+4
=8
√8
=2.828
Answer:
the answer is [tex]\sqrt 8[/tex], or 2.83 cm.
Step-by-step explanation:
You need to use the pythagorean theorem to solve this. It states that [tex]a^{2} + b^{2} = c^{2}[/tex]. a is one leg of the triangle, b is the other leg, and c is the hypotenuse (the slanted line that connects them). We need to do [tex]2^{2}[/tex] to find this. Since [tex]2^{2}[/tex] is 4, we know both legs are 4 [tex]cm^{2}[/tex]. 4 + 4 = 8. Since c is squared, we need to find the square root of 8, or just leave it as is. the final answer is [tex]\sqrt{8}[/tex], or 2.83. Hope this helped! :]

If x increases by 7 in each row of a table of values, and the first differences are all equal to 45.5, then the rate of change is:
a) 6.5
b) 455/7
c) 7/455
d) 318.5
Answer:
b i think
Step-by-step explanation: dont yell just tell me if i got it wrong if i did srry
The rate of change when x increases and the first difference equal to 45.5 is 6.5. Then the correct option is A.
What is the slope?The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.
The slope is given as
[tex]\rm Slope = \dfrac{Rise \ or \ fall}{Run}[/tex]
If x increases by 7 in each row of a table of values and the first differences are all equal to 45.5. Then the rate of change will be given by the slope.
[tex]\rm \\Slope = \dfrac{45.5}{7} = 6.5[/tex]
The rate of change is 6.5.

Answer:
x = 2
Step-by-step explanation:
Let's solve your equation step-by-step.
4 ( x − 1 ) = 2 ( 6 − 2 x )
Step 1: Simplify both sides of the equation.
4 ( x − 1 ) = 2 ( 6 − 2 x )
( 4 ) ( x ) + ( 4 ) ( − 1 ) = ( 2 ) ( 6 ) + ( 2 ) ( − 2 x ) (Distribute)
4 x + − 4 = 1 2 + − 4 x
4 x − 4 = − 4 x + 12
Step 2: Add 4 x to both sides.
4 x − 4 + 4 x = − 4 x + 12 + 4 x
8 x − 4 = 12
Step 3: Add 4 to both sides.
8 x − 4 + 4 = 12 + 4
8 x = 16
Step 4: Divide both sides by 8.
8 x / 8 = 16 / 8
x = 2
0/1 Autumn's dog eats the same amount of dog food every day. On day 3, the bag of dog food has 12 pounds of dog food. On day 7, the bag has 10 pounds of dog food. Write an equation that represents the amount of dog food in the bag, y, for any day after opening the bag of dog food, x. Show your work.
Answer:
y - 0.5x
Step-by-step explanation:
Given that the dog eats the same amount of food each day and on day 3, the available quantity of food
= 12 pounds
On day 7 (4 days after), the available quantity of food is 10 pounds. The difference in the amount of food in 4 days
= 12 - 10
= 2 pounds
This means that each day, the amount of food eaten by the dog in one day
= 2/4
= 0.5 pound
Hence the amount of dog food in the bag y for any day after opening the dog food x will be given as
= y - 0.5x

Answer:
8x - 4y = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 and c = - [tex]\frac{3}{4}[/tex] , then
y = 2x - [tex]\frac{3}{4}[/tex] ← in slope- intercept form
Multiply through by 4 to clear the fraction
4y = 8x - 3 ( subtract 4y from both sides )
0 = 8x - 4y - 3 ( add 3 to both sides )
3 = 8x - 4y , or
8x - 4y = 3 ← in standard form

Delaney is saving money in an account that offers 9% simple interest. She deposits 2000 from her grandmother into the account and makes no additional deposits or withdraws. How many years will it take to grow to 4,700
Answer:
15years
Step-by-step explanation:
Given data
Rate= 9%
Principal= $2000
Final amount= $4700
The simple interest formula is given as
A= P(1+rt)
Substitute
4700=2000(1+0.09*t)
4700= 2000+ 180t
4700-2000= 180t
2700=180t
t= 2700/180
t= 15 years
Hence the time is 15years
