solve this -
7(3x-1)-6(2x+3=8(x-2)+1
plsss helpppp
Answer:
x= -2
Step-by-step explanation:
21x-7-12x-6=8x-16+1
9x-13=8x-15
x+2=0
x=-2
Answer:
x=10
Step-by-step explanation:
7(3x-1)-6(2x+3)=8(x-2)+1
= 21x-7-12x-18=8x-16+1
Move the 8x to the other side and combine like terms.
= x-25=-15
Move the -25 to the other side
x= -15+25
x=10
A shelf is supported with brackets as pictured in the diagram below. What is the
width of the shelf?
A 14 in.
B 16 in.
C 12 in.
D 10 in.
The width of the shelf is 10 inches. The correct option is D.
Describe Right Angled Triangle?A right-angled triangle is a triangle that has one angle measuring 90 degrees, which is known as the right angle. The sides adjacent to the right angle are known as the legs of the triangle, while the side opposite the right angle is known as the hypotenuse.
The Pythagorean theorem, which states that in a right-angled triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the legs, is one of the fundamental theorems of mathematics and is used extensively in various fields.
Let's call the width of the shelf "x". According to the given diagram, we have a right triangle where the base is x, the perpendicular is 10 inches, and the angle between the hypotenuse and the perpendicular is 45 degrees.
Using trigonometric ratios, we know that:
tan(45) = perpendicular/hypotenuse
tan(45) = 10/x
Since tan(45) is equal to 1, we can simplify the equation to:
1 = 10/x
Solving for x, we get:
x = 10
Therefore, the width of the shelf is 10 inches.

(3 x 8) x 4 = 3x (blanck)
Answer:
x = 32
Step-by-step explanation:
24 x 4 = 3x
24 x 4 = 96
96 / 3 = 32
x = 32
Answer:
x = 32
Step-by-step explanation:
You want to find x.
First, simplify and combine like terms. Using PEMDAS, do the parenthesis first.
(3 x 8) x 4 = 3x
24 x 4 = 3x
96 = 3x
Now, divide each side by 3 to isolate x.
x = 32

The range of f(x) = |x| is y ≥ 0. If a < 0 and b ≠ 0 for g(x) = a|x| + b, what is the range of function g?
The required range of the function g(x) = a|x| + b is y ≥ 0.
Let's analyze the function g(x) = a|x| + b step by step to determine its range.
The function |x| represents the absolute value of x, which means it always yields non-negative values. Therefore, a|x| will also be non-negative for any value of x.
Adding b to a non-negative value will shift the entire range up by b units, but it will still be non-negative.
Since a < 0, a|x| will be negative when x is positive. However, the absolute value function ensures that it will be positive when x is negative, balancing out the effect.
Finally, adding the constant term b to a|x| makes the entire range of g(x) non-negative.
In summary, the range of g(x) = a|x| + b is y ≥ 0.

What is the EP unit cost of bell pepper if the AP unit cost is 1.10 per pound and the yield percent is 85%?
Answer:
1.30
Step-by-step explanation:
The formula for EP cost is given as:
EP cost = AP cost / yield
From the Question,
AP unit cost = 1.10 per pound
The yield percent = 85%
EP cost = 1.10/85%
EP cost = 1.2941176471
Approximately
The EP unit cost of bell pepper = 1.30
Solve for x in the following figure.
Answer:
x = 80
Step-by-step explanation:
All angles in a triangle add up to 180 degrees.
First, find the angle J:
60+40 = 100, J = 80 because 100+80= 180 degrees.
Now, the two angles on either side of J should also equal 180 degrees. We know that the inner angle is equal to 80 degrees. Thus, the outside angle must equal 100.
x + 20 = 100
x = 80 degrees.
What is the area of the figure?
Answer:
Area of the triangle :---
1/2×base×height
1/2×5×6
15 square unit
15 square unit is the right answer.

= 3.14 x 19^2 x 21
= 23816.41 cubics in
B.
d) The height of the cylinder is 9ft the radius is 3 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 3^2 x 9
= 254.47 cubics ft
e) The height of the cylinder is 8 ft the radius is 13 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 13^2 x 8
= 4247.43 cubics ft
f) The height of the cylinder is 27 ft the radius is 16 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 16^2 x 27
= 21714.69 cubics ft
g) The height of the cylinder is 15 ft the radius is 10 ft.
So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]
= 3.14 x 10^2 x 15
= 4712.39 cubics ft

A card has p meters of lace edging wound on it. Nerys buys n lengths of edging, each x cm long. If Q meters of edging are left on the card, find a formula for Q in terms of P, n and x
Answer:
Q = P - n(x/100)
Step-by-step explanation:
P is the total number of lace edging, n is the number of times the length x is cut from P, and Q is the remnant of the reduction.
So the number of x length is subtracted from P and must be converted to meters (since it is in centimeters) to get Q. That is;
Q = P - n(x/100)
