What is the solution to the equation −p−13=−43p+23(5p−6)?
Answer:
p = 125/73
Step-by-step explanation:
−p − 13 = −43p + 23 (5p − 6)
−p − 13 = −43p + 115p − 138
−p − 13 = 72p − 138
+p +p
-----------------------------
-13 = 73p - 138
+138 +138
-----------------------------
125 = 73p
/73 /73
-----------------------------
125/73 = p
If you need the answer in mixed fraction, then it's --> p = 1 52/73
The solution to the given equation is p = - 1.71
To determine the solution of the given equation,
We will find the value of the variable, p, that satisfies the equation.
From the question, the given equation is
[tex]-p-13 = -43p+23(5p-6)[/tex]
To solve this,
First, Clear the brackets
[tex]-p-13 = -43p + 115p - 138[/tex]
Now, Collect like terms
[tex]-p +43p -115p = -138 + 13[/tex]
[tex]73p = -125[/tex]
Now, divide both sides of the equation by 73
[tex]\frac{73p}{73} = \frac{-125}{73}[/tex]
∴ p = - 1.71
Hence, the solution to the given equation is p = - 1.71

5. Gardener Gary planted 21 rows of tomatoes
and squash. He planted twice as many rows of
tomatoes as rows of squash. How many tomato
plants were planted if there are 12 plants per
row?
Answer:
168
Step-by-step explanation:
first find out how many rows of squash there are
21 = x + 2x
21 = 3x
7 = x
then find out how many rows of tomatoes there are
7 × 2 = 14
if there are 12 plants per row, we can multiply
14 × 12 = 168
Gardener Gary planted 168 tomato plants
How to determine the number of yellow leaves?Let the rows of tomato be x and the rows of squash be y.
So, we have:
x + y = 21
The statement twice as many rows of tomatoes as rows of squash means that:
x = 2y
Substitute x = 2y in x + y = 21
2y + y = 21
This gives
3y = 21
Divide by 3
y = 7
Substitute y = 7 in x = 2y
x = 2 * 7
x = 14
This means that Gary planted 14 rows of tomato.
The number of tomato plants is then calculated using
Tomato plants= 14 * plants per row
This gives
Tomato plants = 14 * 12
Evaluate the product
Tomato plants = 168
Hence, Gardener Gary planted 168 tomato plants

Write the equation of a line with a slope of -2 and a y-intercept of -5
Answer:
y = -2x - 5
Step-by-step explanation:
y = is a standard for any equation, as is the use of x as a variable, unless something else is specified.
-2x is the way to denote a slope of -2, and -5 gives you the y-intercept of 5. One point on this line would be (0, -5).

Manuel wants 30 liters of a mixture of water and 10% lemon juice. He has a mixture of 8% lemon juice and a mixture of 20% lemon juice. How many liters of the 8% and 20% mixtures should he mix to get what he wants?
Manuel needs 20 liters of the 8% and 5 liters of 20% mixtures to be mixed so as to get 30 liters of a mixture of water and 10% lemon juice.
Let x represent the amount of 8% lemon juice in liters and y represent the amount of 20% lemon juice in liters.
Since Manuel wants to produce a 30 liters mixture from 8% lemon juice and 20% lemon juice, hence:
x + y = 30 (1)
Also, Manuel wants 30 liters of a mixture of water and 10% lemon juice, hence:
8% of x + 20% of y = 10% of 30 liters
0.08x + 0.2y = 3 (2)
Solving equation 1 and 2 simultaneously; multiply equation 1 by 0.2 and subtract equation 2 from the result:
0.12x = 3
x = 25 liters
x + y = 30
25 + y = 30
y = 5 liters
Manuel needs 20 liters of the 8% and 5 liters of 20% mixture
