Are 2x + 5 = 9 and -2x = 4 equivalent to each other
Answers
There are not equivalent to each other because the equation 2x+5=9 is equivalent to 2x=4
Answer: no.
Step-by-step explanation: 2x + 5 = 9 so subtract 5 from each side you get 2x = 4
X= 2
If we substitute that back in 2(2) + 5 = 9 so
If you do -2(2) = 4 it’s -4=4 and it’s not equivalent to each other
Because the statement is not correct.
2) Christmas is on its way, so the price of a box of Thornton's chocolates has been increased
by 15%!! A box of Thornton's Continental now costs £17.25. How much did it cost
originally?
Answers
Our regular cost of chocolates is 1.0
New cost is 1.0 + 0.15 = 1.15
1.15 x 17.25 = 19.8375
In the states we round to the hundredth for cost, so it would be £19.84
Alternate method: calculate 0.15 of 17.25 and add that to 17.25
0.15 x 17.25 = 2.5875
17.25 + 2.5875 = 19.8375

289 miles on 10 gallons
Answers
Answer:
28.9 miles per gallon
Step-by-step explanation:
unit rate is usually something per something. Like miles per hour. In this case we have mile per gallon. MPG.
Unit rate is basically A number X per 1 of something.
so in this cares X per gallon.
we want 10 gallons to go to 1 gallon. So we divide by 10 to get to 1. But if we divide by 10 on one side, we have to do it to the other side. so 289/10=28.9
so our final answer is:
28.9 miles per gallon

Step-by-step explanation:
I got this answer by doing (22/7-2/3) and (22/7-2/3)/2 and comparing the results.
(22/7-2/3) = 52/21, which is about 2.47.
(22/7 - 2/3)/2 = 26/21, which is about 1.23.
With this, you can conclude that it would be half the value.

wow his computer is really fast
We have that The laptop that downloads files at a faster rate is Cheryl’s laptop
Y=0.4GB/s
From the question we are told that
9 GB (gigabyte) file in 15 seconds.
Cheryl’s laptop 80 seconds to download a 32 GB file.
Generally the equation for the is mathematically given as
The rate of transfer for DeAndre’s is
X=\frac{9}{15}
X=0.6GB/s
The rate of transfer for Cheryl’s

Answers
Answer:
x = (8√3)/3
Step-by-step explanation:
Reference angle = 30°
Hypotenuse = x
Side length adjacent to reference angle = 4
Apply CAH, thus:
Cos 30 = Adj/Hyp
Cos 30 = 4/x
x × Cos 30 = 4
x = 4/Cos 30
x = 4/(√3/2) (cos 30 = √3/2)
x = 4 × 2/√3
x = 8/√3
Rationalize
x = (8 × √3)/(√3 × √3)
x = (8√3)/3

A hard-boiled egg is removed from a pot of hot water and set on the table to cool. The rate of change of the egg’s temperature T with respect to time t is proportional to the difference between the egg’s temperature in degrees Fahrenheit ( °F) and the room temperature of 75°F. Which of the following is a differential equation that describes this relationship, where k is a constant?
Answers
Answer:
dT/dt = k(T-75)
Step-by-step explanation:
dT/dt = the rate of change of the egg's temperature T with respect to time t
k = constant
(T-75) = difference between the egg's temperature and the room temperature 75 degree
The relationship between the temperature of the egg and that of the room is dT/dt = k(T-75).
From the Newton's law of cooling, the rate of cooling of any object depends on the temperature difference between the object and the surroundings. This is usually expressed in a differential equation.
In this particular instant, the differential equation that shows the relationship between the temperature of the egg and that of the room is dT/dt = k(T-75).
