Which demonstrates the distributive property? *
a + b = b + a
O (a + b) + c = a + (b + c)
a(b + c) = ab + ac
a + 0 = a
Answers
Answer:
a(b + c) = ab + ac demonstrates the distributive property ⇒ C
Step-by-step explanation:
The distributive property is the product of a number by the sum of the other two numbers equal to the sum of the product of the number with each of the other two numbers.
Example: x(y + z) = xy + xz
Let us check the choices to find which of them demonstrates the distributive property
∵ a + b = b + a
→ Adding a and b equals to adding b and a,
∴ It demonstrates the commutative property
∵ (a + b) + c = a + (b + c)
→ Adding the sum of a and b to c equals to adding c to the sum of a and b
∴ It demonstrates the associative property
∵ a(b + c) = ab + ac
→ Multiplying a by the sum of b and c equals the sum of the products
of a, b and a, c
∴ It demonstrates the distributive property
∵ a + 0 = a
→ The additive identity is zero
∴ It demonstrates the additive identity property
∴ a(b + c) = ab + ac demonstrates the distributive property
What is the solution to the inequality 5.25 – b ≥ 6.5? A number line going from negative 5 to positive 5. A solid circle appears between negative 1 and negative 2.

The number line is shaded from the circle to positive 5. A number line going from negative 5 to positive 5. An open circle appears between negative 1 and negative 2. The number line is shaded from the circle to positive 5.
Answers
Given:
The inequality is
[tex]5.25-b\geq 6.5[/tex]
To find:
The solution of the given inequality on the number line.
Solution:
We have,
[tex]5.25-b\geq 6.5[/tex]
Subtract 5.25 from both sides.
[tex]5.25-b-5.25\geq 6.5-5.25[/tex]
[tex]-b\geq 1.25[/tex]
Multiply both sides by -1 and change the sign of inequality.
[tex]b\leq -1.25[/tex]
The value of b always less than or equal to -1.25. Since -1.25 included in the solution set, therefore there is a solid circle on -1.25.
-1.25 lies between -2 and -1. It means the solid circle lies between -1 and -2.
[tex]b\leq -1.25[/tex], so the number line is shaded from the circle to negative 5.
A number line going from negative 5 to positive 5 is the required solution if a solid circle appears between negative 1 and negative 2. The number line is shaded from the circle to negative 5.
Therefore, the correct option is A.

There are 420 grams of sodium in 3 cans of soup. Which equation finds the number of grams of sodium, s, in 1 can of soup? A 1s=34201 over s is equal to 3 over 420 B 3s=14203 over s is equal to 1 over 420 C s420=31s over 420 is equal to 3 over 1 D s1=3420s over 1 is equal to 3 over 420
Answers
Answer:
[tex]1\ can = 140g[/tex]
Step-by-step explanation:
Given
[tex]420 g = 3\ cans[/tex]
Required
Determine the number of grams in 1 can
[tex]420 g = 3\ cans[/tex]
Reorder
[tex]3\ cans = 420 g[/tex]
Divide both sides by 3
[tex]\frac{3\ cans}{3} = \frac{420 g}{3}[/tex]
[tex]1\ can = 140g[/tex]
Hence;
There are 140 grams in 1 can

Claire and Richard are both artists. Claire uses the polynomial 50x^2+250 to decide how much to charge.Richard uses the polynomial 49x^2+350 to charge how much to charge for his painting.In each polynomial x is the height of the paintings feet. To the nearest tenth what height will both Claire and Richard charge for the same amount for a painting?
Answers
Answer:
The height of the painting has to be 10 feet for both Claire and Richard to charge the same amount.
Step-by-step explanation:
The polynomial expression representing the charge for Claire's paintings is:
C = 50x² + 250
The polynomial expression representing the charge for Richard's paintings is:
R = 49x² + 350
Here x represents the height of the paintings feet.
Now compute the value of x such that both Claire and Richard charge the same amount as follows:
C = R
50x² + 250 = 49x² + 350
50x² - 49x² = 350 - 250
x² = 100
x = 100
Thus, the height of the painting has to be 10 feet for both Claire and Richard to charge the same amount.

32 can be simplified to 2^5. this is the fourth root, so you take out four of the 2’s to the outside by the 6. therefore it becomes 6(2) which = 12 along with the other 2 and an x left inside the fourth root “house”. btw i would write it out but brainly doesn’t let me attach pictures for some reason, and i don’t have the symbols on my keyboard. ):
we now simplify 512 in the second term. 512 is the same thing as 32 times 16, which is 2^9. we take out four of the 2’s, leaving us with 2^5. we can take four more 2’s out, leaving us with a 2 and an x in the inside of the fourth root “house”. on the outside we have 2 2’s, leaving us with a product of 4.
third term. 16 can be simplified to 4^2, or 2^4. we can take all four of them out since it’s the fourth root. there are also four x’s, so we take them out, leaving us with 2x. there isn’t anything left in the “house”.
now, we go from left to right. to better illustrate it, i will use “{ }” as the fourth root.
12 {2x} - 4 {2x} + 2x
8 {2x} + 2x . that’s as simplified as it can get. hopefully this helps! ):
what is the value of x in the equation 3(x-2)+4x=10(x+1)
Answers
Answer:
-16/3 =x
Step-by-step explanation:
3(x-2)+4x=10(x+1)
Distribute
3x -6 +4x = 10x +10
Combine like terms
7x -6 = 10x+10
Subtract 7x from each side
7x-6-7x = 10x-7x +10
-6 = 3x+10
Subtract 10 from each side
-6-10 = 3x+10-10
-16 = 3x
Divide by 3
-16/3 = 3x/3
-16/3 =x

Answer: B) [tex]+\infty[/tex]
=================================================
Explanation:
As x goes to positive infinity, we're moving forever to the right.
If we have a point on the curve, then the point will move to the right and it will also move upward forever.
So as [tex]x \to \infty[/tex] we have [tex]y \to \infty[/tex]
Because y = f(x), this is the same as saying [tex]f(x) \to \infty[/tex]
The notation [tex]+\infty[/tex] is the same as [tex]\infty[/tex]
In terms of words, we can say "the curve rises to the right" to describe the end behavior on the right.
