Select all the equations for which x = 9 is a solution?
7 + x = 16
3x = 57
x/2 = 4.5
x – 3 = 12
2x + 4 = 22
Answers
Answer:
7+9=16
9/2= 4.5
2(9) + 4 =22
These are the only equations that x=9 would be correct!
Explanation: 7+9=16, so the first one is correct. 3x9 is 27 not 57. /= division sign, so 9/2= 4.5. 9 plus 3 equals 12 it’s not the other way around. 2x9=18+4=22

What is curved surface area ?
The lateral surface of an object is the area of all the sides of the object, excluding the area of its base and top.
Curved surface area of cylinder
The lateral surface area of a cylinder is the surface area covered by its curved surface only.
Formula for finding the curved surface area of cylinderTotal surface area of cylinder = 2πrh
where,
r is the radius of cylinder
h is the height of the cylinder
According to the given question
we have
a soup can whose shape is of cylinder.
For finding the least amount of paper required to make label we have to calculate the curved surface
A). when, r = 2 inches and h = 6 inches
curved surface area of soup can = 2π×2×6 = 24×3.14 =75.36 square inches
B).
when, r = 2.5 inches and h = 5 inches
curved surface area of soup can = 2×3.14×2.5×5= 78.5 square inches
C).
when r = 3 inches and h = 4 inches
curved surface area of soup can = 2×3.14×3×4= 75.36 square inches
D).
when r=3.2 inches and h = 3 inches
Curved surface area of soup can = 2×3.14×3.2×3= 60.88 square inches.
Hence, when r = 3.2 inches and h = 3 inches can will need least amount of paper to make a new label.
Thus, option D is correct.

The mixed number [tex]17\frac{1}{2}[/tex] % is equal to 0.175.
To convert [tex]17\frac{1}{2}[/tex] % to a decimal, you divide the percentage value by 100.
First, convert the mixed number [tex]17\frac{1}{2}[/tex] to an improper fraction.
[tex]17\frac{1}{2}[/tex] = (2×17 + 1)/2
= 35/2
Next, divide 35 by 2:
35 ÷ 2 = 17.5
Lastly, divide the result by 100:
17.5 ÷ 100 = 0.175
Therefore, [tex]17\frac{1}{2}[/tex] % as a decimal is 0.175.

Answer:
y = 50x
Step-by-step explanation:
Answer:
y = 50x
Step-by-step explanation:
(1 , 50) ; (2 , 100)
[tex]Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{100-50}{2-1}\\\\=\frac{50}{1}\\\\=50[/tex]
(1, 50) , m = 50
y - y1 = m(x -x1)
y - 50 = 50(x -1)
y - 50 = 50x - 50
y = 50x -50 + 50
y = 50x
Lin picked 9 and 3/4 pounds of apples, which was 3 times the weight of the apples Andre picked. How many pounds of apples did Andre pick
Answers
Answer:3 1/4
Step-by-step explanation:
L=9 3/4
L= 39/4 (multiply 9x4 and add 3)/4
3(A)=39/4 (Note: A= Andre)
(1/3)(3/1)a= 39/4 * 1/3
When you cross the 3 in the denominator and divide 3 into 39 it changes that into 13.
13*1=13 numerator and 4*1=4 denominator so it will be 13/4
When you divide 13/4 it becomes 3 1/4
So 3 1/4 lbs of Apples is the correct answer.
Andre picked 13/4 pounds of apples, which is equivalent to 3 and 1/4 pounds of apples.
What is Fraction?A fraction represents a part of a whole.
Let us consider x to represent the weight of apples that Andre picked.
We know that Lin picked 9 and 3/4 pounds of apples, which was 3 times the weight of the apples Andre picked
9 and 3/4 = 3x
We have to solve for x, divide both sides of the equation by 3:
9 and 3/4 ÷ 3 = x
We can convert the mixed number to an improper fraction first:
(9 × 4 + 3) ÷ 4 = 39/4
Now we can divide:
39/4 ÷ 3
= 13/4
=[tex]3\frac{1}{4}[/tex]
Hence, Andre picked 13/4 pounds of apples, which is equivalent to 3 and 1/4 pounds of apples.
