Answer:
x=35
Step-by-step explanation:
A pentagon's sum of interior angles is 540 degrees.
Now, we can set up an equation.
(4x - 57) + (3x + 15) + 4x + (2x - 3) (3x + 25) = 540
Combine similar terms
16x - 20 = 540
16x = 560
x = 35

If a sweatshirt normally costs $40 but it is
marked down 20%. How much would it cost?
Answers
Answer:
$32
Step-by-step explanation:
First, find 20% of 40.
20% as a decimal is 0.20 (20/100)
0.20 x 40 = 8
Now, subtract 8 from the original price.
40 - 8 = 32
Answer:
$32
40 decrease 40%
40 x (1-20%) = 40 x (1-0.2) =32
Sarah peeled 84 oranges in 7 hours. At that rate, how many oranges would she peel in 15 minutes?
Answers
Sarah would peel 3 oranges in 15 minutes
Explanation:
I’m not sure if I did it right but i multiplied 7 by 60 (hours by minutes in an hour) and got 420. Then I divided it by 15 and got 28. Finally, I divided 84 by 28 and I got 3. I don’t if I am late or right for this question though.
Which of the following best describes the graph below?
Answers
Answer:
The correct option is;
A. It is a one-to-one function
Step-by-step explanation:
A function f(x), is a one to one function when each value in the range is given by each unique value in the domain such that each "x" value produces a unique "y" value.
The given graph has a domain of -2 ≤ x < ∞
Within the domain plotted in the graph, all lines with equation "x" = -2, -1, 0..., 4, 5 crosses the graph only once, therefore, for each value of "x", there is only one value of "y", which gives the relationship between the "x" and "y" values as one to one function

if 72 is 40% what is 100%?
Answers
Answer:
180
Step-by-step explanation:
If 40% = 72, 100% can be found like so:
40% = 72
100% = [tex]\frac{100}{1}[/tex] * [tex]\frac{72}{40}[/tex]
You can reduce 40 and 100 by 20 (or probably more, but I'll use 20)
So now we have:
[tex]\frac{50}{1}[/tex] * [tex]\frac{72}{20}[/tex] = [tex]\frac{3600}{20}[/tex]Divide, and you get 180.
To check, we can find 40% of 180.

Step-by-step explanation:
8x8 = 64x then +6x = 70x
Answer:
[tex]2x(4x+3)[/tex]
Step-by-step explanation:
The first thing to factorising this expression is to find the greatest common factor (GCF). For 8x² and 6x the gcf is 2x. So now we divide the 8x² and 6x by the 2x. Which comes out to 4x and 3, these will be inside the parentheses.
So it'll factorise to [tex]2x(4x+3)[/tex] and remember when we are dividing with exponents we subtract the exponents. So [tex]\frac{8x^2}{2x}[/tex] we will divide the coefficients together that'll be 4 and now for the exponents the 2 on the x² minus the 1 on the x will equal 1 so it'll be just x we don't place a one or anything.
If f(x) = 7-2x , find [f(3)+6] ^2
Answers
explanation:
first, substitute f(3) in the expression. you do this by substituting x for 3 in f(x) = 7 - 2x so that equation becomes f(3) = 7 - 2(3) and solve to find that f(3) = 1.
f(3) = 7-2(3)
f(3) = 7-6
f(3) = 1
then substitute this into the expression and solve
(f(3)+6)^2
(1+6)^2
(7)^2

Jenna has already cycled 8 kilometers this year,plus she plans to cycle 2 kilometers during each trip to work.Write an equation that shows the relationship between the number of trips to work t and the total distance cycled d.
Answers
Answer:
[tex]d = 8 + 2t[/tex]
Step-by-step explanation:
Given
[tex]Rate = 2km/trip[/tex]
[tex]Base\ Cycle = 8km[/tex]
[tex]d = total\ distance[/tex]
[tex]t = cycles[/tex]
Required
Determine the expression for this scenario
The expression can be derived from:
[tex]Total\ Distance = Base\ Cycle + Rate * Cycles[/tex]
Substitute d for Total Distance and t for cycles
[tex]d = Base\ Cycle + Rate * t[/tex]
Substitute values for Base Cycle and Rate
[tex]d = 8 + 2* t[/tex]
[tex]d = 8 + 2t[/tex]

Answers
Answer:
B x = 7
Step-by-step explanation:
You know based on the ratio that it's being scaled by 4 times because the one side 4 is 16 in the bigger pentagon.
So if you go the side that matches the one you need to solve, it's 2.5.
2.5 times 4 = 10 so that bigger pentagon side should equal 10.
The equation x-3 = 10
which means x is 7
