Answer:
The total time taken by 3 men to trim the hedge would be 80 minutes.
Step-by-step explanation:
1) The time taken by 4 men to trim the hedge is 1 hour or 60 min.
2) One me would take 4 times more time alone i.e. Time taken by only one man would be 4 hours or 240 min.
3) The time taken by 3 men would be 3 times less than time taken by one man i.e. 240/3=80 min.
#of people = 4
time taken for 4 ppl = 1hr / 60mins
# of people = 3
time taken = 1/x
4 - 1/60
3 - 1/x
cross multiply
x=60/3*4
x=80
hope this helps :)

A mixture of paint calls for 1/3 cups of red paint and 1/2 cup of yellow paint. How many cups of red paint would be needed for every 1 cup of yellow paint?
Step-by-step explanation:
1 cup of yellow paint = 2×1/2 cup.
and that requires then also 2×1/3 Co red paint.
so, 1 cup of yellow paint mixes with 2/3 cups of red paint.
2 and 3 have a smallest common multiple (smallest number that is divisible by both numbers without remainder) of 6.
so, we need to get 6 units of each for a whole number ratio :
6×1/2 = 3 cups of yellow paint mix with 6×1/3 = 2 cups of red paint.

divide $70 into the ratio of 2:7: 1
Answer:
$14:$49:$7
Step-by-step explanation:
To solve this question you first add the ratios.
So 2+7+1, which is 10. You then take this number and divide it by 70 to find 1 part. 70 divide by 10 is 7, which represents 1 part.
7 times by 2 is 14, 7 times by 7 is 49 and 7 times by 1 is 7.
Thus you get the ratio, $14:$49:$7.
And if you add 14+49+7, you get 70!
Five years ago, a father was 3 times as old
as his son, now their combined ages amount
to 110 years. How old are they?
Answer:
Father is 80 years old and the son is 30
Step-by-step explanation:
Let father be x and son be y:
x-5 = 3(y-5)
x = 3y-10 ------ eq1
x+y = 110
x = 110 -y -------- eq2
Now if we combine the 2 equations we get:
3y + y = 110+10
y=30 (sons age)
Substituting in equation 2 we get:
x = 110 - 30
x = 80
Therefore, the fathers age is 80 and the sons age is 30.

The proportional relationships that have a unit rate that is greater than that of the one of the graph are: the first and third tables, and y = 2x.
How to Determine the Unit Rate of a Proportional Relationship?The unit rate can be calculated as, m = y/x. In an equation that represents a proportional relationship, y = mx, the value of m is the unit rate.
Using a point on the graph, (5, 2):
Unit rate of the graph = y/x = 2/5
Unit rate = 0.4.
Unit rate for the first table = 3/5 = 0.6 [greater than 0.4]
Unit rate for the second table = 2/6 = 0.3 [less than 0.4]
Unit rate for y = 2x, is 2 [greater than 0.4].
Unit rate for y = 0.25x, is 0.25 [less than 0.4].
Unit rate for the third table = 2/4 = 0.5 [greater than 0.4]
Unit rate for the second table = 3/8 = 0.375 [less than 0.4]
Those that have a unit rate that is greater than the one of the graph are: the first and third tables, and y = 2x.

a) Solve the system by substitution.
y = 5x – 3
-X – 5y = -11
Answer:
Step-by-step explanation:
the answer 4x-5y +2 = 0. 5y =-4x-2. y = -4x/5 -2/5 slope = -4/5
Answer:
{y,x} = {2,1}
Step-by-step explanation:
// Solve equation [1] for the variable y
[1] y = 5x - 3
// Plug this in for variable y in equation [2]
[2] -5•(5x-3) - x = -11
[2] - 26x = -26
// Solve equation [2] for the variable x
[2] 26x = 26
[2] x = 1
// By now we know this much :
y = 5x-3
x = 1
// Use the x value to solve for y
y = 5(1)-3 = 2
Find the value of x and y
Answer:
x=4
y=5
Step-by-step explanation:
because this lines are all parallel, so 17x-y equals to 180°-117°= 63, then you get 17x-y = 63
also, equally you can get the below one
6x+7y = (180°-121°)
6x+7y = 59.
put them together
17x-y=63 (1)
6x+7y =59 (2)
you can transform the (1) to y= -(63-17x)
then you get the second one
6x+7(-(63-17x))=59
then you get x
finally you get the result of x into any of the equation
you get y ultimately.

Solve by substitution. x=y-9,5x+2y=11
We have two equations :
x=y-9
5x+2y = 11
We just have to plug the value of x in the second equation to find y :
5(y-9) + 2y = 11
5y - 45 + 2y = 11
7y - 45 = 11
7y = 11 + 45
7y = 56
y = 56/7 = 8
Finally, since x = y -9
x = 8-9 = -1

Lamar is a commercial real estate agent who earns a yearly salary of $82,500 plus a 2.5% commission on his total sales. If his total sales in one year are $3.75 million, what are Lamar’s earnings for that year?
Answer:
$176,250
Step-by-step explanation:
Multiply $3.75 million by Tomas commission on his total sales.
Since you can't multiply a percentage you have to turn the commission into a decimal by moving it two spaces to the left. (Note: if it doesn't have a decimal add one add the end of the number then move it two spaces to the left)
$3,750,000 x .025 or 0.025 = $93,750
Add $93,750 to Tomas yearly salary
$93,750 + $82,500 = $176,250
So
If Tomas sold properties that totaled $3.75 million in sales during one year, his earnings for that year would be $176,250

QUICK!!!! I NEED AN ANSWER!! Emily says that the negative sign means opposite of, so -(-45) means the opposite of negative 45, which is 45. Is Emily correct?
Answer:
Yes, Emily is correct.
Step-by-step explanation:
If you have a - sign in front of a number in parenthesis that is negative, then what you are doing is taking the opposite of that negative number. Remember that the opposite of a negative number is a positive number. In this case, we want the opposite of negative five. What is that? It is +45, or 45. So yes, Emily is correct.
