Answer:
Sylvia's cat weighs 3 pounds more than Michelle's cat
Sylvia’s cat weighs 48 ounces more than Michele’s cat.
What is weight?The downward force exerted by any object due to the effect of the earth's gravity is called weight.
Given that:-
Sylvia’s cat weighs 12 pounds Michele’s cat weighs 9 pounds.The difference between the weight = 12 - 9 = 3 pound
1 pound = 16 ounces
3 pounds = 16 x 3 ounces = 48 ounces
Therefore Sylvia’s cat weighs 48 ounces more than Michele’s cat.

Solve step by step -18=2(-q+4)
Answer:
q=13
Step-by-step explanation:
First, you can multiply to distribute 2 over -9 and 4.
-18=2(-q+4)
-18=-2q+8
Then, you can subtract 8 from both sides.
-18=-2q+8
-26=-2q
Finally, you can divide -2 on both sides.
13=q
Now, you can check by plugging in 13 for the value of q in the original equation.
-18=2(-(13)+4)
-18=2(-13+4)
-18=2(-9)
-18=-18
Hope this helps you! :)

3m+8=15, is it quadratic or not quadratic? If your answer is not quadratic, explain.
3m + 8 = 15 is not a quadratic equation. quadratic equation must have the power of 2 in the quadratic term.
Answer:
Definitely not.
Step-by-step explanation:
3m+8=15
A quadratic equation needs to consist of these values:
x^2+x+y
In this case x can be followed by any coefficient but needs to end with a variable to the power of 2. The second part of this question needs to have that variable- but to no power. Finally, the third part is just a regular integer. We can tell 3m+8=15 is not a quadratic because while it has a variable and integer, it does not have a variable to the power of two.

(-7, 3)
(-3, -7)
(-3, 7)
(3, 7)
Answer:
(-3, 7)
Step-by-step explanation:
The rotation of an object turns the object around a fixed point called the center of rotation.
Positive rotations are counterclockwise.
Negative rotations are clockwise.
Therefore, rotation of 90° about the origin means a 90° rotation counterclockwise with (0, 0) as the center of rotation.
The rule for rotation of 90° about the origin is:
(x, y) → (-y, x)
Therefore (7, 3) → (-3, 7)
The rule of 90° rotation about the origin is
(x,y)—»(-y,x)Here given point is
(7,3)The new point is

A circle is drawn on the (x,y) coordinate plane so that the center is at the point (-3,0). If the radius of the circle is 5, then each of the following points lie on the circle's circumference EXCEPT:
Answer:
2,5
Step-by-step explanation:
since radius is 5
each point lies on the circumference that has 5 or -5 in its y coordinates must have -3 in its x coordinate because -3 is the center
then option number 1 is incorrect
second option is correct , -3 + ( -5 ) = -8
third option is correct, -3 + 5 = 2
fourth is correct, -3 is the center and 5 steps on y axis
fifth is the same as fourth but opposite direction
so the first one is the exception

In right-angled triangle, the difference between two of the angles is 20 degrees. a) Work out the Size of the angles in the triangle. b) How many solutions are there to A?
Answer:
The sum of interior angles of a triangle is 180°
In a right triangle, one of the three angles is 90°. Therefore, the sum of the other two angles is 90°.
Let a = one unknown angle
Let b = the other unknown angle
As the sum of the angles is 90°:
⇒ a + b = 90°
As the difference between the two angles is 20°:
⇒ a - b = 20°
Rewriting the first equation to make a the subject:
⇒ a = 90° - b
Substituting this into the second equation and solving for b:
⇒ 90° - b - b = 20°
⇒ 90° -2b = 20°
⇒ 70° = 2b
⇒ b = 35°
Substituting found value for b into a = 90° - b and solving for a:
⇒ a = 90° - 35°
⇒ a = 55°
Therefore, the two unknown angles are 35° and 55°

If the circle has a diameter of 2 inches, then it has a circumference of 6.28 inches.
Answer:
True, the diameter=2in and the circumference=6.28
Step-by-step explanation:
The circumference, C, of a circle is found by the following equation: C = 2 x pi x r where r equals the radius of the circle (or half its diameter) and pi = 3.14159 (a constant).
Thus, 6.28 = 2 x pi x r
Solving for r: 6.28/(2 x pi) = r
or: 6.28/(2 x 3.14) = 6.28/6.28 = r
thus r = 1 and since the diameter equals 2 x r, the diameter is 2.
Which identity or property is used during the first step when solving the equation 23−8x=16(4x−1)?
Additive Identity
Associative Property
Distributive Property
Multiplicative Identity
Answer:
Multiplicative Identity
Step-by-step explanation:
This is what they all basically mean:
Additive Identity - addition
Associative Property - simplifying
Distributive Property - multiplying brackets, or expanding
Multiplicative Identity - multiplication
In this equation, you first expand 16(4x-1) which uses multiplication but only has one bracket meaning, you use multiplicative identity first.
