Which equation is an identity?
A. 5y + 5 = 5y – 6
B. 8 – (6v + 7) = –6v – 1
C. 3w + 8 – w = 4w – 2(w – 4)
D. 6m – 6 = 7m + 9 – m
Answer: C. 3w + 8 – w = 4w – 2(w – 4)
(3w - w) + 8 = 4w - 2w -2(-4)
2w + 8 = 2w + 8

Answer:
Answer:
[tex]x = 13.8[/tex]
Step-by-step explanation:
Given
See attachment for triangle
Required
Find x
To find y, we make use of the relationship between sides lengths 11 & x and angle 37
The relationship is:
[tex]cos(37) = \frac{11}{x}[/tex]
i.e.
[tex]cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]
Make x the subject
[tex]x = \frac{11}{cos(37)}[/tex]
[tex]x = \frac{11}{0.7986}[/tex]
[tex]x = 13.7741[/tex]
[tex]x = 13.8[/tex] -- approximated
Grace used 1,000 milliliters of apple juice to make one batch of fruit punch. How many liters of apple juice does Grace need to triple the recipe?
Answer: 3 L
Step-by-step explanation:
Given
Grace uses 1000 mL of apple Juice to make one batch of fruit punch
If she triples the recipe, then the Juice used is also tripled i.e.
[tex]\Rightarrow 3\times 1000=3000\ mL[/tex]
In littres, it is [tex]3000\ mL=3\ L[/tex]
City A and City B are 540 miles apart on a map. The scale on the map is 1inch:60 miles. How many inches apart on the map should City A and City B measure. Explain how you would solve this problem. What would the final answer be?
Answer: 9 inch
Step-by-step explanation:
Given
Distance between city A and city B is 540 miles
Scale on the map is 1 inch: 60 miles i.e. 1 inch on the map is equivalent to 60 miles in the real situation
suppose the distance between city A and B on the map is x
[tex]\therefore \dfrac{1}{60}=\dfrac{x}{540}\\\\\Rightarrow x=\dfrac{540}{60}=9\ in.[/tex]
Therefore, the distance between city A and B is 9 in.

Shauna buys a full golf club set for $1,145.87 on a 6 month installment plan. If her monthly
payments are $245.82. How much is the finance charge?
Answer: $329.05
Step-by-step explanation:
Since she pays $245.82 monthly and she is paying for 6 months, the amount paid will be:
= $245.82 × 6
= $1474.92
Since she buys the full golf club set for $1,145.87, then her finance charge will be:
= $1474.92 - $1,145.87
= $329.05
The finance charge is $329.05
A charity is selling brooms to raise funds. Each box has 10 brooms. Each broom is sold for $ 15 . If the charity earns $ 50 profit for each box of brooms, how much does each box of brooms cost the charity, in dollars?
Answer:
Total cost= $100
Step-by-step explanation:
Giving the following information:
Each box has 10 brooms. Each broom is sold for $ 15
The charity earns $ 50 profit for each box of brooms.
First, we need to calculate the total revenue per box:
Total revenue per box= 10*15= $150
Now, the total cost:
Total cost= total revenue - total income
Total cost= 150 - 50
Total cost= $100

Which equation doesn't belong? Explain your reasoning. 1. 1/4x = 27 2. 3x = 36 3. 3/4x = 9 4. 4x = 48
Answer:
1/4x = 27
Step-by-step explanation:
Given the equations :
1.)
1/4x = 27 ;
x/4 = 27
x = 27 * 4
x = 108
2.)
3x = 36
Divide both sides by 3
x = 36/3
x = 12
3.)
3/4x = 9
3x / 4 = 9
3x = 9*4
3x = 36
x =. 36/3
x = 12
4. 4x = 48
x = 48/4
x = 12
All other equations equal to 12 except (1)
Rewrite the following expression with rational exponents. 3 sq root -27x^2 y^7
Show your work
Answer:
Step-by-step explanation:
The square root is possible only if y≤0
if y>0 the expression lose meaning, in fact (-)(+)(+) = (-) and a square root of a negative number doesn’t exist. x^2 is a square so it is ever positive if x is not 0
if y≤0 can be rewritten as:
3(-27x^2y^7)^1/2
or if we want simplify the expression:
[tex]3 \sqrt{3^2 * (-3) * x^2 * y^6 * y} = 3^2|x||y|^3 (-3y)[/tex] ^1/2
we have to put the symbol of absolute value between x and y because a x^2 and y^6 are numbers that are ever positive, while x and y^3 can be also negative. Thanks to the simbol of absolute value we can “force” them to be positive
Hello! Could y’all please explain why this is Decay and not growth?
Answer:
This is an Exponential Decay
Step-by-step explanation:
A = 1200(0.85)⁶
The above expression is an Exponential Decay because 0.85 is less than 1
The formula for Exponential Decay
= y = a (1 - r)^t
We equate both equation together
Where
a = 1200
1 - r = 0.85
t = 6
Solving for r
1 - r = 0.85
r = 1 - 0.85
r = 0.15
Converting to Percentage
r = 15% decay rate

let $x be original price
x(0.8)(0.7) = 487.2
x= 487.2/0.8/0.7
x=870
Write an equation of the line with a slope of -3 and a y-intercept of 0
Answer:
-3/9=07+90
Step-by-step explanation:
Answer: y = 0x+3 or y = 3
The slope is 0 and the y intercept is 3. So m = 0 and b = 3.
Plug those into y = mx+b to get y = 0x+3, and that simplifies to y = 3.
This graphs out a horizontal line that passes through the two points (0,3) and (1,3).

Tell whether x and y
are proportional. If so, find the constant of proportionality.

Answer:
Step-by-step explanation:
y is inversely proportional to x; if x increases, y decreases.
Without more info it is not possible to find the constant of proportionality. Recheck the original numerical values. Think: 8 = kxy. You need to know x and y to find the value of k.
