3(x-4)=2(-2x+1) please help
Answer:
[tex]\boxed{\boxed{\sf x=2}}[/tex]
Step-by-step explanation:
[tex]\sf 3\left(x-4\right)=2\left(-2x+1\right)[/tex]
Expand, Apply Distributive property:
→ [tex]\sf 3x-12=-4x+2[/tex]
Add 12 from both sides:
→ [tex]\sf 3x-12+12=-4x+2+12[/tex]
→ [tex]\sf 3x=-4x+14[/tex]
Add 4x from both sides:
→ [tex]\sf 3x+4x=-4x+14+4x[/tex]
→ [tex]\sf 7x=14[/tex]
Divide both sides by 7:
→ [tex]\sf \cfrac{7x}{7}=\cfrac{14}{7}[/tex]
→ [tex]\sf x=2[/tex]

Step-by-step explanation:
15 crates of egg cost 4500 how many crates will 1500 buy
Answer:
5 crates
Step-by-step explanation:
1500/4500 = 1/3
1500 is 1/3 of 4500, so 1500 buys 1/3 of 4500.
1/3 * 15 crates = 5 crates
Answer: 5 crates
Answer:
3 crates for $1,500
Step-by-step explanation:
15 is to x as 4500 is to 1500, or 15 is to x as 3 is to 1. Then x = 3 (crates)
3: A farmer keeps cows and pigs on his farm. The ratio of cows to pigs on the farm is 2:3 (a) What percentage of the animals on the farm are cows? (b) What percentage of the animals on the farm are pigs?
Answer:
(a) 40% of the animals are cows.
(b) 60% of the animals are pigs.
Step-by-step explanation:
(a) You have to find the percent of the cows. 2:3 can be written as 2/5 for the cows and you have to figure out x/100.
2/5 = x/100
5*20 = 100
2*20 = x
40 = x
(b) The rest of the animals on the farm are pigs so you have to subtract 40 from 100 for the answer.
100-40 = y
60 = y
Create a probability model for the outcome of performing 2 spins. What is the probability of NOT landing on yellow or red at all?
Using the concept of probability, the probability of not landing on yellow or red at all is 1/4.
Creating a square model of the two spins :
Red(R) ; Blue(B) ; Green(G) ; Yellow(Y)___ R ___ B ___ G ___ Y
R_ RR __ RB __ RG __ RY
B_ BR __ BB __ BG __ BY
G_ GR __GB __ GG __GY
Y_ YR __ YB __ YG __ YY
Sample space = 4² = 16Combinations without red and yellow :
{BB, BG, GB, GG} Number of selections without red or yellow = 4Recall :
Probability = required outcome / Total possible outcomesP(without Red or Yellow) = 4/16 = 1/4
Hence, the probability of not landing on yellow or red at all is 1/4.

what year was it, exactly 4 centuries before 1965?
Based on the number of years in a century, we can calculate that the 4 centuries before 1965 was 1565.
A century refers to a period of 100 years.
If we are looking for a period of 4 centuries therefore, this would be:
= 4 x 100
= 400 years
4 centuries before 1965 would therefore be:
= 1965 - 400
= 1565
In conclusion, the answer is 1565.

Answer:
ABC= 60
DCE= 65
DEF= 105
Step-by-step explanation:
Answer:
60°; 65°; 115°Step-by-step explanation:
ΔABC is equilateral since all sides marked as congruent. Therefore:
m∠ABC = 60°ΔCDE is isosceles since two sides marked as congruent:
m∠DCE = m∠DEC = 1/2(180° - 50°) = 1/2(130°) = 65°∠DEF forms a linear pair with ∠DEC, so they sum to 180°:
m∠DEF = 180° - 65° = 115°A line containing the points (x, 1) and (2, 4) has a slope of 1/4. Find the value of x.
Answer:
Step-by-step explanation:
Givens
m = 1/4
y2 = 4
y1 = 1
x2 = 2
x1 = x
m = (y2 - y1) / (x2 - x1)
Solution
1/4 = (4 - 1) / (2- x) Simplify
1/4 = 3 / (2 - x) Cross multiply
2- x =12 Subtract 1 from both sides
-x = 12 - 2
-x = 10 Multiply by -1
x = -10
Check
1/4 = (4 - 1) / (2 - - 10)
1/4 = 3/(2 + 10)
1/4 = 3 / 12
1/4 = 1/4
Odd as the answer is, it does check.

it takes clay 1/2 hour to mow his lawn how much of the yard will be mowed after 1/3 hour
Answer:
Step-by-step explanation:
Clays rate is 1/2 hour per lawn. We can write this as Rate = 3/2 hr/lawn.
If Clay mows for 1/3 hour, we can determine the amount of lawn mowed by dividing the 1/3 hour by the rate:
(1/3 hr)/(3/2 hr/lawn) = (1/3)*(2/3) = 2/9 of a lawn.
If the height of a cone is 7.5 cm and the radius is 2 cm, find the approximate volume of the cone.
Answer:
The volume of the cone is approximately 31.43 cm³Step-by-step explanation:
We know that:
Volume of cone: πr²h/3h = 7.5r = 2Work:
πr²h/3=> π x r² x h/3=> 22/7 x 2² x 7.5/3=> 22/7 x 4 x 2.5=> 22/7 x 10=> 220/7=> 31.43 (Rounded to nearest hundredth.)Hence, the volume of the cone is approximately 31.43 cm³

A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 95% pure antifreeze. The company wants to obtain 285 gallons of a mixture that contains 55% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed?
Answer:
premium: 165 gallonswater: 120 gallonsStep-by-step explanation:
Let 'a' represent the amount of 95% antifreeze in the mix. Then the amount of water is (285 -a). The mix has this amount of antifreeze in it:
0.95a +0(285 -a) = 0.55(285)
a = 0.55/0.95(285) = 165 . . . gallons of 95%
285 -a = 285 -165 = 120 . . . . gallons of water
There are 120 gallons of water and 165 gallons of premium antifreeze in the mixture.
