The quotient of a number and -7, decreased by 2, is 10
Answer:
Let the required number be x
The quotient of a number and -7, decreased by 2, is 10
According to the above problem, we get
[tex] \frac{x}{( -7)} - 2 = 10 \\ \frac{x}{( - 7)} = 10 + 2 \\ \frac{x}{( - 7)} = 12 \\ x = ( - 7) \times 12 \\ \boxed{x = - 84}[/tex]
Therefore, the required number is -84.
-84 is the right answer.HELP !!!

Simplify the expression by using the properties of rational exponents. Write the final answer using positive exponents only.
Answer:
A. [tex] {h}^{7} [/tex]
Step-by-step explanation:
[tex] {h}^{ \frac{7}{3} } \times {h}^{ \frac{14}{3} } [/tex]
[tex] {h}^{ \frac{7}{3} + \frac{14}{3} } = \frac{7}{3} + \frac{14}{3} [/tex]
[tex] \frac{7 + 14}{3 } = \frac{21}{3} [/tex]
[tex] 21÷3 = 7[/tex]
[tex] = {h}^{7} [/tex]

Step-by-step explanation:
the domain is the interval of the x (input) values.
in other words, is g(x) invalid for certain x ?
it does not look like it. it looks like g(x) is valid for every possible value of x from -infinite to +infinite.
the range is the interval of possible y (functional) values.
and that is clearly valid for every y between -1 and +infinity.
Suppose g(x) = f(x - 1) - 5. Which statement best compares the graph of g(x) with the graph of f(x)
Answer:
g will be shifted down 5 units and right 1 unit on the x- y plane

A truck driver drove 48 miles in 45 minutes. At this rate, how many miles can the truck driver drive in one hour?
__ miles in one hour
Answer:
I am almost positive that the answer is 64 miles in one hour.
Step-by-step explanation:
In an hour the truck driver will cover the distance of 64 miles.
What is speed?Speed is defined as the ratio of the time distance traveled by the body to the time taken by the body to cover the distance. The speed is a scalar quantity and does not require direction to represent it.
Given that a truck driver drove 48 miles in 45 minutes. The distance covered by the truck in an hour will be calculated as below:-
45 minutes ⇒ 48 miles
1 minute ⇒ 48 / 45
60 minute ⇒ ( 48 x 60 ) / 45
1 hour ⇒ 64 miles
Therefore, in an hour the truck driver will cover the distance of 64 miles.

How does the value of the digit 2 in 2000 compare with the value of the digit 2 in 200
Answer:
The value of 2 in 2000 is 10 times greater than the value of 2 in 200
Step-by-step explanation:
from the value of 2 in 200 to reach 2000, it takes 10 times as much because we're moving only one place (which is the thousand's digit).

what is the arithmetic sequence for 128,96,64,32 fraction form
--------------------
4n-1Step-by-step explanation:
128 and r = 3 over 4 (127,) . (3 over 4) apply the product rule to 3 over 4 and I don't kno the rest but that's ita community center is trying to raise $1680 to purchase exercise equipment. the center is hoping to receive equal contributions from members of the community. write and algebraic expression to determine how much will be needed from each person if n people contribute. Then evaluate the expression for 10, 12, 14, or 16 people.
Answer:
Required expression would be:
c(n) = 1680/n, where c(n) - is the contribution amount, n- number of contributors.For different values of n we get:
c(10) = 1680/10 = 168c(12) = 1680/12 = 140c(14) = 1680/14 = 120c(16) = 1680/16 = 105Lets find f(n) formula
[tex]\boxed{\sf f(n)=\dfrac{1680}{n}}[/tex]
Now
[tex]\\ \sf\longmapsto f(10)=\dfrac{1680}{10}=168[/tex]
[tex]\\ \sf\longmapsto f(12)=\dfrac{1680}{12}=140[/tex]
[tex]\\ \sf\longmapsto f(16)=\dfrac{1680}{16}=105[/tex]
[tex]\\ \sf\longmapsto f(14)=\dfrac{1680}{14}=120[/tex]
