Answer:
Remove parentheses.
y-10=-3\times -2y−10=−3×−2
2 Simplify 3\times -23×−2 to -6−6.
y-10=-(-6)y−10=−(−6)
3 Remove parentheses.
y-10=6y−10=6
4 Add 1010 to both sides.
y=6+10y=6+10
5 Simplify 6+106+10 to 1616.
y=16y=16

A ramp for wheelchair access to the gym has a slope of 5% (that is, the ramp rises 5 feet vertically for every 100 feet of horizontal distance). The entire ramp is built on level ground, and the entrance to the gym is 2 feet above the ground. What is the horizontal distance, in feet, between the ends of the ramp? a 4 b 10 c 40 d 100 e 400
Answer:
C 40
Step-by-step explanation:
Using proportions, it is found that the horizontal distance, in feet, between the ends of the ramp is:
c 40
This question is solved by proportions, using a rule of three.The slope of 5% means that when the vertical distance rises by 5 feet, the horizontal distance changes by 100 feet.What is the horizontal distance for a vertical distance of 2 feet?The rule of three is:
5 feet V - 100 feet H
2 feet V - x feet H
Applying cross multiplication:
[tex]5x = 200[/tex]
[tex]x = \frac{200}{5}[/tex]
[tex]x = 40[/tex]
Hence, 40 feet, option c.

What is the positive solution for (x-4)(x+5) = 0
Answer:x=4
Step-by-step explanation:
You can split this up into two equations
x-4=0
x+5=0
To solve each:
x-4=0
Add 4 to each side
x=4
------------
x+5=0
Subtract 5 from each side
x=-5
So your two solutions are -5 and 4 but you want the positive one so the answer is x=4
what is the simplest form of 3x^3 + x^2 + 2 ( x^3 - 4x^2 )
Answer:
−8x^4 + 5x^3 + x^2
Step-by-step explanation:
3x^3 + x^2 + 2 (x^3 − 4x^4)
Apply the distributive property.
3x^3 + x^2 + 2x^3 + 2 (−4x^4)
Multiply −4 by 2.
3x^3 + x^2 + 2x^3 − 8x^4
Simplify by adding terms.
Add 3x^3 and 2x^3.
5x^3 + x^2 − 8x^4
Simplify the expression.
Move x2.
5x^3 − 8x^4 + x^2
Reorder 5x^3 and −8x^4.
−8x^4 + 5x^3 + x^2

CAN SOMEONE PLEASE HELP ME I'LL GIVE YOU BRAINLIEST
Answer:
x = 25
Step-by-step explanation:
From the given picture,
In ΔMLN,
m∠NML + m∠MLN + ∠LNM = 180°
61° + 39° + m∠LNM = 180°
100° + m∠LNM = 180°
m∠LNM = 180° - 100°
m∠LNM = 80°
If JK║MN and JN is a transverse intersecting these parallel lines at N and J,
∠LNM ≅ ∠LJK [Alternate interior angles]
(3x + 5)° = 80°
3x = 80 - 5
3x = 75
x = 25

Erin's family has completed 70% of a trip. They have traveled 35 miles.
How far is the trip?
Answer:
Their trip is 50 mile long.
Step-by-step explanation:
I first divided 70 by 35 to get two.The two represents 1 mile = 2%. So then I subtracted 70 from 100 to get 30 then I divided 30 by 2 to get 15. Then I added 15 to the original 35 to get 50 miles for their 100%/destination of their trip. Hope this helps! Have a great day!

Which graph shows y = 2x -1/2
Answer:

Graph (C) shows the equation of line y = 2x -1/2.
What is equation of line?A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system.
The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line.
The given equation of line is,
y = 2x - 1/2 (1)
Standard equation of the line is y = mx + c
By comparison, slope of the line (1),
m = 2
To plot graph, find x and y intercept,
x intercept of line at y = 0,
0 = 2x - 1/2
2x = 1/2
x = 4
y intercept of line at x =0,
y = -1/2
The graph of the line is represented here.
Correct answer is option (3).

A jwelery supply shop buys silver chains from a manufactorer for c dollars each and then sells the chains at a 57% markup
write the markup as a decimal
Answer: The expression for the retail price of a silver chain is 1.4c.
Step-by-step explanation:
Let the amount of jewelry be c dollars.
Rate of mark up = 40%
So, Amount of mark up would be
[tex]\frac{40}{100}[/tex] times c
= 0.4c
So, Amount after mark up would be
c+0.4c
=1.4c
Answer: The expression for the retail price of a silver chain is 1.4c.
