jane is twice as old as Barbara. Michael is 7 years older than Jane. If Michael is 21, which equation could be used to find Barbara's age
Step-by-step explanation:
J = 2b
M = J + 7
M = 21
J = 21 - 7
J = 14
B = 7
Equation:
If M is J+7, so then J = 21-7. J is 2*b, so 2*b = 21-7. Then you subtract and divide.

3 gardeners can plant 18 trees in 30 minutes.
How many gardeners would it take to plant 45 trees in 45 minutes?
Answer:
5 gardeners
Step-by-step explanation:
1 gardener - 6 trees in 30 min
or 1 tree in 5 min so in one minute gardener can plant 1/5 tree
in 45 min 1 gardener can plant 9 trees
so you would need 5 gardeners to do 45 trees in 45 min
We have that the number of men needed to plant 45 trees in 45 minutes is
From the question we are told that
3 gardeners can plant 18 trees in 30 minutes.
plant 45 trees in 45 minutes?
Generally the equation for the One gardeners time of planting is mathematically given as
Since
3 gardeners can plant 18 trees in 30 minutes.
Therefore
[tex]X=\frac{18}{30}*\frac{1}{3}\\\\X=\frac{1}{5}trees/min[/tex]
Since
45 trees in 45 minutes
Therefore
1 tree for every min
Hence
Men need for 1 tree for every min is
[tex]1=x*\frac{1}{5}\\\\x=5[/tex]
Therefore
x=5men would plant 45 trees in 45 minutes

Wayne is hanging a string of lights 59 feet long around the three sides of his patio, which is adjacent to his house. The length of his patio, the side along the house, is 3 feet longer than twice its width. Find the length and width of the patio.
Answer:
The width is 18 feet and the length is 42 feet
Step-by-step explanation:
Let x feet be the width of the patio. The length of the patio is 6 feet longer than twice it’s width, then the length of the patio is 2x+6 feet.
Wayne is hanging a string of lights 78 feet long around the three sides of his patio, which is adjacent to his house. The side with length 2x+6 feet is adjacent to the house, so Wayne is hanging a string along three sides with lengths x ft, x ft and 2x+6 ft.
x+x+2x+6=78
4x=78-6
4x=72
divide both sides by 4
x=18 ft
The width 18 ft
2*18+6=36+6=42 ft
The length 42 ft

Answer:
235/3
Step-by-step explanation:
First, let's make a varible x. Let x be the "what number" part in the question.
Now, Let's convert the words into an equation.
We get:
60% * x = 47
Simplifing, we get:
0.6 * x = 47
0.6x = 47
x = 47 / 0.6
x = 47 / [tex]\frac{6}{10}[/tex]
x = 47 / [tex]\frac{3}{5}[/tex]
x = 47 * 5/3
x = 235/3
A law firm is going to designate associates and partners to a big new case. The daily rate charged to the client for each associate is $700 and the daily rate for each partner is $1700. The law firm assigned 4 more partners than associates to the case and was able to charge the client $21200 per day for these lawyers' services. Write a system of equations that could be used to determine the number of associates assigned to the case and the number of partners assigned to the case. Define the variables that you use to write the system
Answer: 700a+1700p= 21200

Answer:
125/216
25/72
5 / 72
1 / 216
Step-by-step explanation:
n = 3
p = 1/6 = 0.1667
Using the relation :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
F(0) = 3C0 * (1/6)^0 * (1 - 1/6)^3
F(0) = 1 * 1 * (5/6)^3
F(0) = 1 * 125/216
F(0) = 125 / 216
F(1) = 3C1 * (1/6)^1 * (1 - 1/6)^2
F(1) = 3 * 1/6 * (5/6)^2
F(1) = 3 * 1 / 6 * 25/36
F(1) = 75 / 216
F(1) = 25 / 72
F(2) = 3C2 * (1/6)^2 * (1 - 1/6)^1
F(2) = 3 * 1 / 36 * (5/6)^1
F(2) = 3 * 1/36 * 5/6
F(2) = 15/216
F(2) = 5/72
F(3) = 3C3 * (1/6)^3 * (1 - 1/6)^0
F(3) = 1 * 1 /216 * (5/6)^0
F(3) = 1 * 1/216
F(3) = 1/216

The proportion of the value is is 18/a = a/16 , A proportion is an equation that sets two ratios at the same value.
What is proportion ?A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls) There are 1 in 4 boys and 3 in 4 girls. 0.25 are male (by dividing 1 by 4)
If two ratios depict the same relationship, they are said to be proportionate. By writing two ratios as fractions and then reducing them, one can determine if they are proportionate. Your ratios are proportional if the reduced fractions are equal.
Given:
It is a similar triangle to the one in the example.
The hypotenuse measures 18 units in length.
The leg is a certain length.
The portion of the hypotenuse is 16 units long.
We must ascertain the ratio that was employed to calculate the value of a.
We will use the geometric mean leg rule to discover the ratio needed to calculate the value of a.
When using the "leg rule," we have;
hypotenuse/leg
leg/part
Substituting the values of hypotenuse, leg and part, we get;
18/a = a/16
Thus the proportion of the value is is 18/a = a/16
The complete question is :
Which proportion can you use to find the value of a?
