Miles read 4 books in the first half of March. By the end of March, the library had added Miles to the top-readers board for reading more than 10 books in a month.Let x represent how many books Miles read in the second half of March. Which inequality describes the problem?
Answer:
[tex]x>6[/tex]
Here, [tex]x[/tex] denotes number of books read by Miles in the second half of March
Step-by-step explanation:
Given: Miles read 4 books in the first half of March.
Also, Miles read more than 10 books in a month.
[tex]x[/tex] denotes number of books read by Miles in the second half of March.
To find: inequality that describes the problem.
Solution:
Total number of books read in month of March = Number of books read by Miles in the first half of March + Number of books read by Miles in the second half of March = [tex]4+x[/tex]
Also, Miles read more than 10 books in a month.
Therefore,
[tex]4+x>10\\x>10-4\\x>6[/tex]

Find the slope of the line that passes through the pair of points (6,-2) and (5,-4).
Show all work necessary and write your final answer in the box.
Answer:
slope = -10/7Step-by-step explanation:
co-ordinates = (6,-2) (5,-4)
slope = (y² - y¹) / (x² - x¹)
slope = (-4 - 6) / (5 - (-2))
slope = (-10) / (5+2)
slope = (-10) / 7
slope = -10 / 7

What is the mass in kg of a
solid metal cuboid with
dimensions 4cm, 5cm and
3cm and a density of
20g/cm3
Answer:
work out the area which is 4x5x3 this being 60 then divide this by 20 to get 3
The answer is 3kg
Answer:
[tex]density = mass \div volume \\ 20 = x \div 4 \times 3 \times 5 \\ 20 = x \div 60 \\ 20 \times 60 = x \\ x = 1200 \\ 1200 \div 1000 = 1.2kg[/tex]

What value of x satisfies the equation below?
[tex]\frac{-2x - 6}{5} = 4[/tex]
Answer: -13
Step-by-step explanation:
1. Isolate x: move 5 to the otherside
=> -2x-6=4*5 => -2x-6=20
2. Move 6 to the otherside: -2x=20+6 => -2x=26
3. Divide both sides by -2
=> x=26/-2 => x=-13

Jim's parents keep a chart on the wall where they mark how much Jim grows each year. When Jim was 15, he grew 1/4 of an inch and when he was 16, he grew 1/2 of an inch. In total, how much did Jim grow in during those two years?
Answer: 3/4 inch
Step-by-step explanation:
When Jim was 15, he grew 1/4 of an inch and when he was 16, he grew 1/2 of an inch.
His growth during those two years will be:
= 1/4 + 1/2
= 1/4 + 2/4
= 3/4 inch
His growth increased by 3/4 inches.

Step-by-step explanation:
In the diagram, △ABC∼△CDE. Write an equation for line k
Answer:
Step-by-step explanation:
Line AB is parallel to line CD (k) so they have the same slope.
slope=m=(y2-y1)/(x2-x1)
m=(6-0)/(4-0)
m=6/4=1.5
y=mx+b, we know m=1.5 so
y=1.5x+b, and we know it passes through point (4,0) so we can solve for b
0=1.5(4)+b
0=6+b
b=-6 so line k is
y=1.5x-6
