Answer:
Marcel reads 20 pages every 2 days.
Then, in one day, she reads:
20/2 = 10 pages per day.
Now, we know that in one day she reads 10 pages, then we can subdivide the number 350 in N groups of 10 pages, each one of these N groups needs one day to be read, then 350 pages will be read in N days:
N = 350/10 = 35 days.
Xion reads 8 pages per day.
Then to read 350 pages, he neds:
N = 350/8 = 43.75 days
Amber reads 56 pages in 7 days.
Then she reads 56/7 = 8 pages per day (Same as Xion)
Then she also needs 43.75 days to read 350 pages.
Francessca reads 55 pages in 5 days.
Then she reads 55/5 = 11 pages per day.
To read 350 pages, she needs:
350/11 = 31.82 days
Then the one that needs less days to read 350 pages is Francessca.
What is the equation of the line that passes through the point (5,6) and has a slope of 2?
PLZ HELP AND EXPLAIN HOW YOU SOLVE!!! THANK YOU AND HAVE A GREAT DAY!!
Answer:
Answer is at the bottom!!
Step-by-step explanation:
y = - \frac{2}{5} x - 2
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
rearrange 2x + 5y = 10 into this form
subtract 2x from both sides
5y = - 2x + 10 ( divide all terms by 5 )
y = - \frac{2}{5} x + 2 ← point- slope form with slope m = - \frac{2}{5}
Parallel lines have equal slopes hence
y = - \frac{2}{5} x + c is the partial equation of the parallel line
to find c, substitute ( 5, - 4 ) into the partial equation
- 4 = - 2 + c ⇒ c = - 4 + 2 = - 2
y = - \frac{2}{5} x - 2 ← equation of parallel line
Hope this helps!!
8 increased by the sum of t and 3
Answer:
8+(t+3)
Step-by-step explanation:
the sum is when you add two numbers together. so you would add t with 3 and out it in parentheses so you make sure that happens first. then you add it to 8 since 8 is being increased by the sum.
Henry can run 12 laps in 30 minutes. How long will it take him to run 16 laps.

11) Which of the following is zero of the polynomial x^3+x^2+x+1
1
-1
both options 1 and 2
None
please answer
Answer:
Answer: -1
Step-by-step explanation:
The Polynomial Remainder Theorem
It states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).
We have the polynomial:
[tex]f(x)=x^3+x^2+x+1[/tex]
And we need to determine if x=1 and/or x=-1 are zeros of the polynomial.
Considering the polynomial remainder theorem, if we try any value for x, and the remainder is zero, then that value of x is a root or zero of the polynomial.
Find:
[tex]f(1)=1^3+1^2+1+1[/tex]
f(1)=4
Thus, x=1 is not a zero of f(x)
Now, find:
[tex]f(-1)=(-1)^3+(-1)^2+(-1)+1[/tex]
[tex]f(1)=-1+1-1+1=0[/tex]
Thus, x=-1 is a zero of f(x)
Answer: -1

Given: 4d=1/3(c-d) Proof= c=13d
Proof:
Multiply both of the sides by 3. You would get 12d = c - d. Add d on both sides, and you would get c = 12d
Here, we are required to proof c = 13d from 4d=1/3(c-d)
Ultimately, c = 13d (proof)
We have;
4d=1/3(c-d)Cross product
4d × 3 = c - d
therefore, By collecting like terms;
C = 12d +d
and Ultimately, c = 13d ......

Joe goes to the store to buy milk that cost x + $3, bread that cost x + $2.25, and 3 bags of potato chips that cost x + $1.50 each. Write an equivalent expression to represent what he spent.
Given:
Milk cost = x + $3,
Bread cost = x + $2.25,
3 bags of potato chips cost = x + $1.50 each.
To find:
The equivalent expression to represent what he spent.
Solution:
1 bag of potato chips cost = x + $1.50
3 bag of potato chips cost = 3(x + $1.50).
Total cost = Milk cost + Bread cost + Cost of 3 bags of potato chips
[tex]\text{Total cost}=(x+\$3)+(x+\$2.25)+3(x+\$1.50)[/tex]
[tex]\text{Total cost}=x+\$3+x+\$2.25+3x+\$4.50[/tex]
[tex]\text{Total cost}=(x+x+3x)+\$(3+2.25+4.50)[/tex]
[tex]\text{Total cost}=5x+\$9.75[/tex]
Therefore, the required expression is 5x+$9.75.

A cement path consists of six equal-sized cement squares arranged in a row to form a rectangle. If the total area of the path is 96 square feet, what is the length in feet of the path?
Answer:
24 feet
Step-by-step explanation:
Given that:
The length of the rectangle is 6 times the side of a cement square.
Now, this rectangle is formed from 6 squares;
The total area of the path of this square = 96 square feet;
The area of each square now = 96/6 = 16 square feet
Recall that:
Area of a square = S²
where S is the side length
16 = S²
S = [tex]\sqrt{16}[/tex]
S = 4 ft
The length of the path in feet now is: L × w
= 6 × 4
= 24 feet.

If you randomly select a card from a well-shuffled standard deck of 52 cards, what is the probability that the card you select is not a 4? (Your answer must be in the form of a reduced fraction.)
Answer:
12/13
Step-by-step explanation:
A standard deck of cards has four suites
Total number of cards = 52
Total number of cards which are 4 is = 4
The probability that the card selected is 4 = 4/52 = 1/13
S, the probability that the selected card is not a 4 = 1 - (1/13 )= 12/13
