Answer:
f=39
Step-by-step explanation:
hi! first, we can multiply by 12 on both sides to eliminate the 12 in the denominator.
f+3= (7/2)*12
f+3=84/2
f+3=42
now, subtract 3 on both sides.
f=39

Q.13 66.66, Q.14 0.141 cm
Step-by-step explanation:
John has 1 1/4 acres of land. it takes 80 1/2 pounds of fertilizer to cover one acre. How much fertilizer does John need to cover his land.
[tex]area \: of \: land \: with \: john \: = 1 \frac{1}{4} \: acres \ \\ \\ = \frac{(4 \times 1) + 5}{4} \\ \\ \\= \frac{9}{4} \: acres[/tex]
Quantity of fertilizer needed to cover 1 acre of land :-
[tex] \: \ \\ = 80 \frac{1}{2} \: pounds \\ \\ = \frac{(2 \times 80) + 1}{2} \\ \\ = \frac{81}{2} \: pounds[/tex]
Quantity of fertilizer needed by John to cover his land :-
[tex] \frac{9}{4} \times \frac{81}{2} [/tex]
[tex] \frac{(9 \times 2 ) \times (81 \times 4)}{8} [/tex]
[tex] \frac{(18 \times 324)}{8} [/tex]
[tex] = \frac{5832}{8} [/tex]

Answer: 10
Step-by-step explanation:
The x-intercepts means when y equals 0, or when the function crosses the x-axis.
0 = (x-6)^2 - 16
16 = (x-6)^2
Take the square root of both sides:
4 = (x-6)
Add 6 to both sides to get:
x = 10

Use point-slope form, y - y1 = m(x - x1), to find the linear equation of a line that passes through the points
(2, -1) and (10, 7).
y =
x+
Answer:
y = ✔ 1x+ ✔ -3
Step-by-step explanation:
The equation of the line passing through the points (2, -1) and (10, 7) is y = x - 3.
What is the point slope form of the equation of a line?The point slope form of a line is given by -
y - y₁ = m(x - x₁)
Given is a line that passes through the points (2, -1) and (10, 7).
The point - slope form of a line is given by the general equation -
y - y₁ = m(x - x₁)
We will find the slope of the line as follows -
m = (7 + 1)/(10 - 2) = 8/8 = 1
The line passes through the point (2, -1), so we can write the equation of line as -
y - (- 1) = x - 2
y + 1 = x - 2
x - y = 3
y = x - 3
Therefore, the equation of the line passing through the points (2, -1) and (10, 7) is y = x - 3.

Step-by-step explanation:
Barry made the model to show multiplying a fraction by a fraction. Which multiplication sentence does the model show? A grid with 3 rows of 6 columns showing 18 squares total. The 12 squares in the top two rows are shaded yellow, the 15 squares in the first 5 columns are shaded blue. The shading overaps to make green in 10 squares. 13×23=29 26×56=518 13×26=19 23×56=59
Given:
Number of rows = 3
Number of columns = 6
Number of square boxes = 18
yellow square boxes in the top two rows = 12
Blue square boxes in the first 5 columns = 15
Number of green boxes (shading overlaps) = 10
To find:
The model to show multiplying a fraction by a fraction.
Solution:
2 rows out of 3 are shaded yellow.
Fraction for yellow = [tex]\dfrac{2}{3}[/tex]
5 columns out of 6 are shaded blue.
Faction for blue = [tex]\dfrac{5}{6}[/tex]
10 out of 18 squares are green.
Faction for green = [tex]\dfrac{10}{18}=\dfrac{5}{9}[/tex]
Now,
[tex]\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{10}{18}[/tex]
[tex]\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{5}{9}[/tex]
Therefore, the correct option is D.
The correct option is D.
The calculation is as follows:
2 rows out of 3 are shaded yellow.
Fraction should be [tex]2\div 3[/tex]
Now
5 columns out of 6 are shaded blue.
Fraction should be [tex]5 \div 6[/tex]
And,
10 out of 18 squares are green.
Fraction should be [tex]10 \div 18 = 5\div 9[/tex]
Now
[tex]\frac{2}{3} \times \frac{5}{6} = \frac{10}{18}\\\\ \frac{2}{3} \times \frac{5}{6} = \frac{5}{9}[/tex]

Step-by-step explanation:
T = L(8 + RS)
Solve for R
Answer:
Step-by-step explanation:
T=L(8+RS)
T=L8+LRS
T-L8=LRS
R=T-L8/LS
The required solution to the given equation is R = (T - 8L)/LS.
What is the equation?The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.
The equation is given in the question, as follows:
T = L(8 + RS)
Apply the distributive property of multiplication,
T = L × 8 + L × RS
T = 8L + LRS
Rearrange the terms in the above equation,
T - 8L = LRS
Divided by LS into both sides, and we get
R = (T - 8L)/LS
Thus, the required solution to the given equation is R = (T - 8L)/LS.

Answer:
The equation has an Inifinite amount of solutions
Step-by-step explanation:
2 ( 3g + 2 ) = 1/2 ( 12g + 8 )
First use the distributive property of multiplication -
6g + 4 = 6g + 4
6g cancels out from both sides of the equation -
4 = 4
When both sides of an equation are the same there is an infinite amount of solutions.
