Answer:
Each triangle weighs 3 grams.
Step-by-step explanation:
On the left side, there are 6 squares (12 grams) 3 circles (9 more grams), and 2 triangles (2x grams).
On the right side, there are 3 squares (6 grams) 2 circles (6 grams), and 5 triangles (5x grams).
This makes the equation 21 + 2x = 12 + 5x.
Let's find x.
21 + 2x = 12 + 5x
Subtract 5x from both sides.
21 - 3x = 12
subtract 21 from both sides.
-3x = -9
Divide by -3.
x = 3.
Each triangle weighs 3 grams. Let's prove this.
21 + 2x = 12 + 5x
21 + 2(3) = 12 + 5(3)
21 + 6 = 12 + 15

•Point B: (-2,9)
•Point C: (2,-9)
•Point D: (2,9)
Which point is the first quadrant?
Answer:
Point D: (2, 9)
Step-by-step explanation:
The first quadrant includes points that have a positive x coordinate and a positive y coordinate. The only point that meets these conditions is point D, (2, 9).

What are the solutions to the equation (10−x)(3x−9)=0?
Answer:
10−x)(3x−9)=0
−3x2+39x−90=0
−3(x−3)(x−10)=0
x=3 or x=10
The solutions to the equation (10 - x)(3x - 9) = 0 are x = 10 and x = 3.
Given that the equation (10 - x)(3x - 9) = 0
The factors will have the form (ax + b)(cx + d), where a, b, c, and d are constants.
To find values for a, b, c, and d such that (ax + b)(cx + d) is equal to 0
To determine the solutions of (ax + b)(cx + d), equate each term to zero and solve for x which gives the solutions.
The two solutions of (ax + b)(cx + d) are -b/a and -c/d.
To find the solutions to the equation (10 - x)(3x - 9) = 0, set each factor equal to zero and solve for x.
Setting (10 - x) = 0 gives:
10 - x = 0
To isolate x, subtract 10 from both sides of the equation:
10 - x - 10 = 0 - 10
Simplifying gives:
-x = -10
Multiplying both sides by -1 to solve for x:
(-1)(-x) = (-1)(-10)
x = 10
So, one solution is x = 10.
Now, setting (3x - 9) = 0, gives:
3x - 9 = 0
To isolate x, we add 9 to both sides of the equation:
3x - 9 + 9 = 0 + 9
Simplifying gives:
3x = 9
Dividing both sides by 3 to solve for x:
(1/3)(3x) = (1/3)(9)
x = 3
Therefore, the second solution is x = 3.
The solutions to the equation (10 - x)(3x - 9) = 0 are x = 10 and x = 3.

Answer:
A
Step-by-step explanation:
X is 6 or less so we can start there x≤6. X is also more than -5 so we can do that. -5<x. If we put those two together we get -5<x≤ 6.
The expression for the statement is option (A) [tex]-5 < x\leq 6[/tex] is the correct answer.
What is an inequality?An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is the condition of being unequal.
For the given situation,
The statement of inequality is x is 6 or less and more than – 5
The inequality for x is 6 or less ,
⇒ [tex]x\leq 6[/tex]
The inequality for x is more than – 5
⇒ [tex]x > -5[/tex]
Thus x is 6 or less and more than – 5 can be written as inequality,
⇒ [tex]-5 < x\leq 6[/tex]
Hence we can conclude that the expression for the statement is option (A) [tex]-5 < x\leq 6[/tex] is the correct answer.

Kelly is 9 years old .In two years Kelly will be 1/3 of his mothers age now .What is his mother age
Answer: 31
Step-by-step explanation:
9 + 2 = 11. 11 is how old Kelly is in 2 years.
1/3 of 33 is 11. Kelly's mother is 33 in two years, meaning two years ago, Kelly's Mother is 31.
Here is the full equation. K = Kelly. M = Kellys Mom
9k = m
2k + 9k = m + 2m
11k = m + 2
11k = [tex]\frac{m}{3}[/tex]
M + 2 = 33

This is a rectangular prism,
Here length = 16 m
Width = 6 m
Height = 3 m
Surface area of rectangular prism = 2( bl + lh + hb )
Where,
b – base length of the rectangular prism.
l – base width of the rectangular prism.
h – height of the rectangular prism.
Putting these values, surface area = 2(16×6 + 16×3+ 3×6)
= 2( 96+48+18) = 2×162 = 324m
