Sarah’s sister has seven less than twice as many books as Sarah. Since the two girls share a room, they are all on the same bookshelf.
Which expression represents the number of books (x) on the shelf?
1. 2x-7
2. 7-2x
3. x+2x-7
4. x+7-2x
Answer:
x + 2x-7
Step-by-step explanation:
x is the amount of books Sarah has
2x-7 is how many books Sarah's sister has
Add them together : x+2x-7
Rowan reads at a constant rate of 1.5 pages per minute and has already
read 20 paqes. Kennedy has read 25 pages and reads at a constant rate
of ; page per minute. In how much time will Rowan and Kennedy have
read the same number of pages
Using linear functions, it is found that Rowan and Kennedy will have read the same number of pages in 10 minutes.
What is a linear function?
A linear function is modeled by:[tex]y = ax + b[/tex]
In which:
a is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.For Rowan, we have that:
He has already read 20 pages, hence the y-intercept is [tex]b = 20[/tex].He reads 1.5 pages per minute, hence the slope is [tex]a = 1.5[/tex]Then:
[tex]y_R = 1.5x + 20[/tex]
For Kennedy, we have that:
He has already read 25 pages, hence the y-intercept is [tex]b = 25[/tex].He reads 1 page per minute, hence the slope is [tex]a = 1[/tex]Then:
[tex]y_K = x + 25[/tex]
They will have read the same number of pages after x minutes, for which:
[tex]y_R = y_K[/tex]
Then:
[tex]1.5x + 20 = x + 25[/tex]
[tex]0.5x = 5[/tex]
[tex]x = \frac{5}{0.5}[/tex]
[tex]x = 10[/tex]

812.16 is what percent of 752?
Answer:
108
Step-by-step explanation:
For 100, our answer will be 108
For 752, our answer will be x
100*x = 108*752 (In Step 1 and 2 see colored text; Diagonal multiplications will always be equal)
x = 108*752/100 = 81216/100 = 812.16
Answer: 108 percent of 752 is 812.16

Submit Answer
Skin for Now
Answer:
w=-1/6 or w=-3
Step-by-step explanation:
Substitute the value of x and y into the first equation and solve for w:
[tex]y=6x^4+7x^2\\10=6(\sqrt{w+1})^4+7(\sqrt{w+1})^2\\10=6(w+1)^2+7(w+1)\\10=6(w^2+2w+1)+7w+7\\10=6w^2+12w+6+7w+7\\0=6w^2+19w+3[/tex]
Solve for w with the quadratic formula:
[tex]w=\frac{-b\±\sqrt{b^2-4ac}}{2a} \\w=\frac{-19\±\sqrt{19^2-4(6)(3)} }{2(6)}\\w=\frac{-19\±\sqrt{361-72}}{12} \\w=\frac{-19\±\sqrt{289} }{12} \\w=\frac{-19\±17}{12}[/tex]
After simplifying, we get either w=-1/6 or w=-3.
Not sure if w needs to satisfy all conditions while maintaining everything as real numbers, because if w=-3, then x is an imaginary number. But both values work just as fine.

it 1 inch represent 10mmiles on a map then how many inches will represent 900 miles
Answer: 90 inches will represent 900 miles
Step-by-step explanation:
A simple way to find this using mathematical methods is to set up a proportion:
1/10=x/900
Then you would cross multiply getting:
900=10x (then divide by 10 on both sides to get the variable alone)
x=90
So 90 inches will represent 900 miles

Are these lines perpendicular, parallel, or neither based off their slopes?
61x – 2y = -2
y = 3x + 12
Answer:
Perpendicular
Step-by-step explanation:
The lines intersect at (0.4,13.2)
The lines represented by the given equations are neither perpendicular nor parallel.
The given equations are: 61x - 2y = -2 and y = 3x + 12. To determine if the lines represented by these equations are perpendicular, parallel, or neither, we need to compare their slopes.
The slope of a line can be determined by the coefficient of x in the equation.
The first equation can be rewritten in slope-intercept form as y = 30.5x + 1, where the slope is 30. The second equation is already in slope-intercept form with a slope of 3.
Since the slopes are not equal and not negative reciprocals, the lines represented by these equations are neither perpendicular nor parallel.

Solve for x. Enter your answer in the box. x = ° An irregular pentagon with five different measured angles and five unequal sides. The angles of the pentagon are x degrees, 121 degrees, 108 degrees, 102 degrees, and 100 degrees.
Step-by-step explanation:
sum of interior angles of a polygon with n sides =
(n−2) × 180°
for a pentagon that is 3×180 = 540°
therefore,
540 = x + 121 + 108 + 102 + 100 = x + 431
x = 109°

Step-by-step explanation:
The distance formula is:
[tex]d = \sqrt {\left( {x_2 - x_1 } \right)^2 + \left( {y_2 - y_1} \right)^2 }[/tex]
Plug the given coordinates into the equation:

The diagram shows a circular pond with a path around it . The path has a width of 1m .the pond has a radius of 5m. Work out the area of the path . Give your answer correct to 3 significant figures
The area of the path if the circular pond with a path around it is 34.557 m²
Circle
Circle is the locus of a point such that its distance from a fixed point known as the center is constant.
The area of the circle (A) with radius r is given by:
A = πr²
Area of the pond with path = π(5m + 1m)² = π(6)² = 113.097 m²
Area of the pond = π(5m)² = π(5)² = 78.54 m²
Area of path = 113.097 m² - 78.54 m² = 34.557 m²

4-2(3 - 2x) = 2
i need help pls
We have to find the value of x so first we will subtract 4-2
4-2(3 - 2x) = 2
2 ( 3 - 2x ) = 2
Now we will multiply 3 - 2x by 2
6 - 4x = 2
Take 6 to the other side and its sign will become minus
- 4x = 2 - 6
- 4x = -4
No we will take - 4 to the other side and will divide it by -4
