solve 3(x-4) = 12x. circle your final solution
Answer:
9x-12
Step-by-step explanation:
3*x = 3x
3*-4= -12
3x - 12 = 12x
12x-3x = 9x
9x-12
Answer: x = -4/3
Step-by-step explanation:
3(x−4)=12x
Step 1: Simplify both sides of the equation.
3(x−4)=12x
(3)(x)+(3)(−4)=12x (Distribute)
3x+−12=12x
3x−12=12x
Step 2: Subtract 12x from both sides.
3x−12−12x=12x−12x
−9x−12=0
Step 3: Add 12 to both sides.
−9x−12+12=0+12
−9x=12
Step 4: Divide both sides by -9.
-9x/-9 = 12/-9
x = -4/3
George hiked from the top of a hill to the valley floor. The elevation at the top of the hill is 127 feet above sea level. The valley floor is 52 feet below sea level. George stopped at a rest stop that is at an elevation exactly halfway between the top of the hill and the valley floor. What is the elevation, in feet, of the rest stop? Show your work
Answer:
The elevation of the rest stop is 37.5 feet above sea level.
Step-by-step explanation:
Given that the elevation at the top of the hill is 127 feet above sea level and The valley floor is 52 feet below sea level.
So, the total length from the top of the hill to the valley floor
[tex]l= 127+52 = 179[/tex] feet
So, length of halfway [tex]= l/2=179/2=89.5[/tex] feet ...(i)
Assuming that the stop for rest, the halfway between the top of the hill and the valley floor, is at x feet above sea level.
So, the length between the stop position and the valley floor [tex]= 52 +x[/tex] feet.
As the stop position is at half-way, so by using equation (i), we have,
[tex]52 + x = 89.5 \\\\\Rightarrow x =89.5-52 \\\\[/tex]
[tex]\Rightarrow x=37.5[/tex] feet
Hence, the elevation of the rest stop is 37.5 feet above sea level.

Pedro had $235 in his saving account when Jim had $450 in his account. Look at the situation in the image. Which inequality shows when the amount of money in Pedro’s account is greater than the amount of money in Jim’s account?
Answer:
$450>$235
Step-by-step explanation:
This is because, when 235 is subtracted from 450 there is a great difference thats why $450 is greater than $235
Mr. Stokes bought 6 1/2 pounds of meat for a party. He used 2 1/4 pounds of meat to make tacos. The rest he used to make 1/4 pound burgers. How many burgers did Mr. Stokes make?
9514 1404 393
Answer:
17
Step-by-step explanation:
The remaining amount of meat is ...
6 1/2 - 2 1/4 = 4 1/4 = 17/4 . . . pounds
The number of 1/4 pound burgers that can be made with that amount of meat is ...
(17/4)/(1/4) = 17/1 = 17
Mr. Stokes made 17 burgers.
What is x=7 in slope intercept form
Please help
Answer: x=7 or undefined

An ice chest contains 7 cans of apple juice, 6 cans of grape juice, 6 cans of orange juice, and 4 cans of mango juice. Suppose that you reach into the container and randomly select three cans in succession. Find the probability of selecting three cans of mango juice.
Answer:
4/1771Step-by-step explanation:
Step one:
given
sample space
7 cans of apple juice,
6 cans of grape juice,
6 cans of orange juice, and
4 cans of mango juice
Sample size= (7+6+6+4)
= 23
Step two:
Required
The probability of randomly selecting three cans of mango juice in succession
Note: we are selecting without replacement
let the probability of selecting three cans of mango juice be
the first selection is= 4/23
The second = 3/22
the third= 2/21
[tex]P(x)= 4/23*3/22*2/21[/tex]
[tex]P(x)= \frac{4*3*2}{23*22*21} \\\\P(x)= \frac{4}{23*11*7}\\\\P(x)= \frac{4}{1771}[/tex]
What is the value of z? Please provide an explanation, thanks!
Answer:
z=7
Step-by-step explanation:
72°+(8z-8)°+(9z-3)°=180° (a triangle contains 180° and vertical angles are equal)
(8z-8)°+(9z-3)°=180°-72°
17z°-11°=108°
17z°=108°+11°
17z°=119°
z°=119°/17°
z°=7°
z=7

A road starts at sea level and climbs steadily, reaching an elevation of 2000 feet after 8 miles, as shown in the diagram.
8 mi
5 mi
2000 ft
Note: Figure is not drawn to scale.
What is the elevation in feet of the road 5 miles from the starting point?
A. 1000
B. 1250
C. 750
D. 1500
Answer:
I think the answer is 1500
Step-by-step explanation:
Elevation of the road at 5 miles from the starting point is 1250 ft.
Similarity of triangles: If two triangles are similar, their corresponding sides will be proportional.
Given in the question,
Two triangles formed by a road are ΔADE and ΔABC (As shown in the figure attached).
Since, ∠A ≅ ∠A (Reflexive property)
∠AED ≅ ∠ACB (right angles)
ΔADE ~ ΔABC (By A-A property of similarity)
In these similar triangles, corresponding sides will be proportional.
[tex]\frac{AB}{BC}=\frac{AD}{DE}[/tex]
[tex]\frac{8}{2000}=\frac{5}{DE}[/tex]
[tex]DE=\frac{5\times 2000}{8}[/tex]
[tex]=1250[/tex] miles
Therefore, elevation of the road at 5 miles from the starting point will be 1250 ft.
Option (B) will be the answer.
