Answer:
D, [tex]\frac{1}{2}x-3[/tex]
Step-by-step explanation:
Remember order of operations: parentheses first, then exponents, then multiplication/division, and finally addition/subtraction.
In this case, since there is no way to further simplify the parentheses, we can leave them be. But the negative sign in front of the parentheses is like multiplying it by -1. It needs to be distributed into the parentheses like so:
[tex]-(\frac{1}{4}x+5)=-\frac{1}{4}x-5[/tex]
We can now substitute that into the expression:
[tex]\frac{3}{4}x+2-\frac{1}{4}x-5[/tex]
From here, we can combine like terms:
[tex]\frac{2}{4}x-3[/tex]
And finally, we can simplify 2/4 to get:
[tex]\frac{1}{2}x-3[/tex]

The peak of Mount Everest, Earth's tallest point, is about 5 1/2 miles above sea level. The bottom of the Mariana Trench, Earth's deepest point, is about 6 9/10 miles below sea level. If you could place Mount Everest at the bottom of the Mariana Trench, how far from sea level would its peak be?
Answers
Answer:
11 7/10 miles below sea level
Step-by-step explanation:
Given the following :
Peak of Mount everest = 5 1/2 miles above sea level
Bottom of Mariana trench = 6 9/10 miles below sea level
If mount everest is placed at the bottom of Mariana trench
. It's be will be :
Since sea level could be considered as a 0 point;
Adding the height and depth of both should give us the depth below sea level:
(6 9/10 + 5 1/2) miles
6 + 5 (9/10 + 1/2)
11 (9 + 5)/10
11 14/10
11 7/10
= 11 7/10 miles below sea level
The volume of a pyramid is V = 1/2 Ah. If V = 60 when h = 9, find A.
Answers
Answer:
Here,
Volume of pyramid (V) = 1/2 ×A×H
Given, V= 60 , H= 9
Now place the value of V and H in :
V= 1/2 ×A×H
60= 1/2 ×A × 9
60×2= 9A
120/9 = A
Hence, A= 120/9

What is the slope of the line
represented by the equation
2y = 5x + 4?
Answers
Answer: The slope is 5/2.
Step-by-step explanation:
Convert the equation into slope intercept form, ( y=mx+b)
2y = 5x + 4 Divide each side by 2
y = 5/2x + 2 In this form the slope will be the coefficient of x variable.
The coefficient is the number that comes before x.
In this case, the slope is 5/2.
The cost to buy tickets online for a dance show is $60 per ticket. a. Write a function that represents the cost C(x) (in $) for x tickets to the show. b. There is a sales tax of 5.5% and a processing fee of $8.00 for a group of tickets. Write a function that represents the total cost T(a) for a dollars spent on tickets. c. Find (T ∘ C)(x). d. Find (T ∘ C)(6) and interpret its meaning in the context of this problem.
Answers
Step-by-step explanation:
Given
cost of ticket=$60
a. the cost of x tickets is
C(x)=60x
b. sale tax of 5.5% of $60 is 5.5/100*60
0.55*60=$3.3
processing fee = $8
the total cost T(a) for a dollars spent on tickets.
T(a)=60a+3.3+8
T(a)=60a+11.3
c. Find (T ∘ C)(x).
T(x)=60x+11.3
d. Find (T ∘ C)(6)
T(6)=60*6+11.3
T(6)=360+11.3
T(6)=$371.3
This means that for 6 tickets with a tax of 5.5% and a processing fee of $8 the cost will be $371.3

Answer:
x= -6
Step-by-step explanation:
Step 1: Subtract 34 from both sides.

I cut along piece of wood into 50cm pieces I manage to cut w, pieces of wood and there is 20cm left over . How long was the wood to start with
Answers
Answer:
50w+20 (cm)
Step-by-step explanation:
There would be w pieces of 50cm wood pieces and one 20cm wood piece.
wood length = 50w +20
Step-by-step explanation:
Given
Length of Pieces = 50cm
Number of Pieces = w
Left over = 20cm
Required
Determine the length of the wood
Start by multiplying the number of pieces by the length of each pieces
Result = length * number
Result = 50 * w
Result = 50w
Lastly, add the leftover to get the actual length of the wood
Woodlengrh = result + leftover
Substitute 50w for Result and 20 for Leftover
woodlength = 50w + 20
Hence, the length of the wood is 50w + 20

John earned $36 for 8 hours of work. Earnings are directly proportional with hours worked.how much did he earn when he worked 30 hours.
Answers
Answer:
$135
Step-by-step explanation:
First, find the unit rate of money earned (36/8=4.5)
Then, multiply the unit rate of money earned by 30 (4.5 x 30 = $135)
I apologize if my wording is incorrect.
The total earnings for the 30 hours is $1350 if John earned $36 for 8 hours of work. Earnings are directly proportional to hours worked.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that:
John earned $36 for 8 hours of work. Earnings are directly proportional to hours worked.
Earnings ∝ hours
E ∝ T
E = kT
Here k is the constant
36 = 8k
k = 36/8
E = (36/8)T
Plug T = 30
E = (36/8)(30)
E = $1350
Thus, the total earnings for the 30 hours is $1350 if John earned $36 for 8 hours of work. Earnings are directly proportional to hours worked.

A bus covers a distance of 90km at a uniform speed. Had the speed been 15km/hour it would have taken 30 minutes less for the journey. Find the original speed of the bus.
Answers
Answer:
Step-by-step explanation
Let's say d = distance, r = speed and t = time
We know the distance formula is :
distance = speed x time
d = r multiplied by t
d = rt
If the speed is 15km/hr, the time would be 30 minutes shorter.
Since d = rt,
90 = 15t
t = 6,
This means the time taken for the bus to complete the journey at 15km/hr would be 6hrs.
Originally though, the journey takes 30 minutes longer.
So we can say t = 6.5 hrs , and we know d = 90
Now we use the distance formula:
d = rt, since we want to find the original speed, we want to find r.
Speed = distance/time
r = d/t
r = 90/6.5
r = 180/13
Therefore the original speed is 180/13 km/hr
