Answer:
Keith's rate in chapters per hour is 8.
Step-by-step explanation:
Divide his 48 chapters by the 6 hours he read and in total it will be a ratio of 8 chapters to one hour.
Keith's rate in chapters per hour will be 8.
What is unit rate?There is independent quantity, and a quantity which depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called rate of increment of dependent quantity per unit increment in independent quantity.
We are given that Keith reads 48 chapters of a book in 6 hours.
Therefore,
We need to Divide his 48 chapters by the 6 hours he read
48/6
= 8
Hence, in total it will be a ratio of 8 chapters to one hour.

Help me giving all good reviews!!
Answer:
152
Step-by-step explanation:
We need to find how many people like dogs but not cats. We can see that 152 people wrote that they like dogs. The other options were that they liked cats, both or neither. So we can assume that the 152 people that picked dogs do not like cats as there is no other option. So this is the answer. Also, you can create a venn diagram with this.

The area of the triangle is 65 square feet. The height of the triangle is 26ft. What is the length, in feet, of the base of the triangle?
(There’s no drawing of a triangle here)
Answer:
X · 26 x 1/2 = 65
X · 13 = 65
Divide by 13 on both sides:
X = 5
Let's double check
5 x 26 x 1/2 = 65, it works!

5. 31 x + 2z - Y
= 16 for y
How do I solve this equation?
9514 1404 393
Answer:
y = 31x +2z -16
Step-by-step explanation:
You solve this the same way you solve any 2-step linear equation.
Step 1: Subtract the terms that don't include y.
31x +2z -y -(31x +2z) = 16 -(31x +2z)
-y = 16 -31x -2z . . . . . . . . . simplify
Step 2: Divide by the coefficient of y. (Equivalently, multiply by -1.)
y = -16 +31x +2z
__
I don't like leading minus signs, so I would rearrange the terms:
y = 31x +2z -16

The Solution of the Inequality is y> 2.1.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have,
Inequality: 2y + 7 > 15.2
Now, simplifying the inequality
2y > 15.2-7
2y > 8.2
y> 8.2 /2
y> 2.1
So, the solution is y>2.1

If the sum of two consecutive odd number is 16 , find the numbers.
Answer:
Two find the two terms from a sum of two consecutive odd integers
Let the first term be, n
Then the next consecutive odd number is. n + 2
So the two terms sum to n + n +2 = 16
so 2n + 2 =16
Subtract 2 from both sides
2n = 14
Divide both sides by 2
n = 7 which is the first term
and n + 2 = 7 +2 = 9 is the second term
PLEASE HELP!!!!! Find BM.
Answer:
BM = 26
Step-by-step explanation:
The vertical slash marks indicate that AM and BM are equal. So all you need to do is equate the AM = BM
3x - 4 = 4x - 14 Add 14 to both sides
3x - 4 + 14 = 4x Combine
3x + 10 = 4x Subtract 3x from both sides
10 = 4x - 3x Combine
x = 10
But that is not the answer. The question asks for BM
BM = 4x - 14 Substitute x = 10
BM = 4*10 - 14
BM = 40 - 14
BM = 26

A car is driving at 80 kilometers per hour. How far, in meters, does it travel in 3 seconds?
Answer:
It travels 3,600 meters in 3 seconds.
Step-by-step explanation:
90 kilometers an hour is 90 thousand meters per hour.
there are 60 mins in one hour, and 60 seconds in each minute, or 3,600 seconds in one hour.
So in 1 second, the car travels 90,000 meters, or 3,600 seconds.
In 2 seconds, it travels twice that.
2 x 90,000 = 50 meters

Solve the given equation.
[4w – 1] = 5w + 37
-
A) Ø
B) {-4}
C) {4}
D) {-4, 4}
Answer: B
Step-by-step explanation:
if 4w-1 ≥0 or w > 1/4 then
|4w-1|=4w-1
4w-1=5w+37 ==> w=-38 (exclude since not >1/4)
else
4w-1 < 0 or 4w <1 or w < 1/4
|4w-1|=-(4w-1)
-(4w-1)=5w+37
-4w+1=5w+37
9w=-36
w=-36/9
w=-4 ( which is < 1/4)
