Simplify 5 - 4(x - 1) - 2(x + 1)
Answer:
-6x+7
Step-by-step explanation:
Start by multiplying (x-1) by -4 and (x+1) by -2.
Then you will have the equation 5-4x+4-2x-2
Next, just find your like-terms.
Your like-terms are 5,4,-2 and -4x, 2x
Then, for easier for calculation, just use the equation:
-4x-2x+5x+4-2
Your final answer should then be:
-6x+7
Kenji drives 18.4 miles in 16 minutes. He passes a sign, which gives the speed limit as 60 mph. By how much, in mph, did Kenji's average speed exceed the speed limit?
The amount of speed by which kendri exceeded the speed limit is; 9 mph
We are given;
Distance; d = 18.4 miles
Time; t = 16 minutes = (16/60) hours
Now, the formula for speed is;
Speed = distance/time
Thus, let's Calculate kenji's speed;
Kenji's speed = 18.4/(16/60)
Kenji's speed = 69 mph
We are told that the speed limit is to be 60 mph, this means that kendri exceeded the speed limit by;
69 - 60 = 9 mph

the sum of two and a number is less than five
Answer:
Please check the explanation.
Step-by-step explanation:
Given the English statement
''The sum of two and number is less than five''.
Let us breakdown the statement.
Let 'n' be the number. The sum of two and number = 2 + nWe know that the less than symbol is denoted by '<' which is used for comparison.
Thus, the statement 'The sum of two and a number is less than five' is algebraically represented as:
2 + n < 5Let us solve the algebraic expression.
[tex]2+n<5[/tex]
Subtract 2 from both sides
[tex]2+n-2<5-2[/tex]
Simplify
[tex]n<3[/tex]
Thus, the solution is:
[tex]2+n<5\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:n<3\:\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:3\right)\end{bmatrix}[/tex]

Kahleela starts the engine on her small private airplane. The engine drives a propeller with a radius of 8.5 feet and its centerline 11.5 feet above the ground. At idle, the propeller rotates at a constant speed of approximately 800 revolutions per minute. The height of one propeller tip as a function of time is given by h = 11.5 + 8.5 sin(800t), where h is the height in feet and t is the time in minutes. Find h when t = 5.5 minutes.
Answer:
a=21.1
Step-by-step explanation:
You can use the given (incorrect) equation and fill in the value of t to find h:
h = 12.5 +9sin(750(3.5)) = 3.68 . . . . feet
__
Or, you can use the correct equation, or just your knowledge of revolutions:
h = 12.5 +9sin(750(2π·3.5)) = 12.5 . . . . feet
in 3.5 minutes at 750 revolutions per minute, the propeller makes 2625 full revolutions, so is back where it started — at 12.5 feet above the ground.

A. 3.1 feet is the answer i believe.........

Answer:
369
Step-by-step explanation:
* = Multiply
5*229=1145
Lakes * Average = Total Average Depth of Five Lakes
(1145-369)/4=194 (it worked)
4 is the other lakes, 369 would be considered the largest lake.

A store down the street is selling a console 50% of from 236.87 if i were to buy the console wit my 490.45 how much money will i get back?
Answer:
$372.01
Step-by-step explanation:
50% of $236.87 is half of it, which means the console is being sold for $118.44 because:
235.87/2 = 118.435
Round this to the nearest cent:
$118.44
If you have $490.45, and you spend $118.44, it means that you subtract the cost from your own money:
490.45 - 118.44 = 372.01
You will have $372.01 left.

if 100 grams of meat costs 30 pesos,how much does 8 kilograms costs
Solution:
Answer:
Check:
Solution:
First, we need to find out the amount for one kilogram. Since 100 grams = 30 pesos, and 1000 grams = 1 kilogram, we need to multiply it by 10.
30 x 10 = 300
Now we have the amount for 1 kilogram. Now in order to get the amount for 8 kilograms, we need to multiply it by 8.
300 x 8 = 2400 pesos
Answer:
The answer is 2,400 pesos.
Check:
30 x 10 = 300 So 300 pesos for a kilogram
300 x 8 = 2400 So 2400 pesos for 8 kilograms.
Kellie is purchasing the package of dog food shown (dog kibble 7pounds) how many 8 ounce servings can she feed her dog
Answer:
14 servings
Step-by-step explanation:
Step 1
We convert 7 pounds to ounces
0.0625 pound = 1 ounce
7 pounds = x
Cross Multiply
0.0625x = 7
x = 7/0.0625
x = 112 ounces
Step 2
The number of 8 ounce servings she can give to her dog is calculated as:
8 ounces = 1 serving
112 ounces = x servings
Cross Multiply
8 × x = 112 × 1
8x = 112
x = 112/8
x = 14 servings
Therefore, the number of 8 ounce servings she can feed her dog is 14

Use the Distributive Property to write an expression that is
equivalent to 4(y - 3).
Answer:
4y-12
Step-by-step explanation:
To multiply a sum (or difference) by a factor, each summand (or minuend and subtrahend) is multiplied by this factor and the resulting products are added (or subtracted).
If the operation outside the parentheses (in this case, the multiplication) is commutative, then left-distributivity implies right-distributivity and vice versa, and one talks simply of distributivity.
The equivalent value of the expression is A = 4y - 12
Given data ,
Let the equation be represented as A
Now , the value of A is
A = 4 ( y - 3)
On simplifying the equation , we get
A = 4 ( y - 3 )
So , the left hand side of the equation is equated to the right hand side by the value of A = 4 ( y - 3 )
Opening the parenthesis on both sides , we get
A = 4 ( y - 3 )
Using the distributive property , we get
A = 4 ( y ) - 4 ( 3 )
On further simplification , we get
A = 4y - 12
Taking the common factor as 4 , we get
A = 4 ( y - 3 ) = 4y - 12
Therefore , the value of A = 4y - 12
Hence , the expression is A = 4y - 12

the average screen time for middle school students is 240 minutes per day. In 2020 students went into virtual learning and the average screen time is 70 percent longer. What is the total percent of screen time this year?
Answer:408=screen time
Step-by-step explanation:240+168 70%=168
make sure to like with the heart
Answer:
I believe 408 minutes a day
Step-by-step explanation:
So, I have my own method which is to divide the whole (in this case, 240) by 10 and multiply by whatever percent you have to multiply by and you add it to the whole.
ex.
240/10 = 24
24x7=168
240+168= 408
to do with 100s like 73% then divide the whole by 100 :)
