earnings? Simplify your answer.
(1 point)
15t – 4
15t + 8
–3t – 4
–3t + 8
I'll be glad to check your answer.
okay, sounds gre8, thank you Ms, Sue!!!
Ummm, im not trying to be rude, but i really need that question checked for me...😐😐😐
You didn't post anything for Ms. Sue to check!
Total = 6t+2 + 9t-6 =
oh i see, oops i didnt realize that before... i feel stupid, srry Ms. sue!!!, but thank you anyway!!!!
yo bot Suppose you earned 6t + 2 dollars on Monday and 9t – 6 dollars on Tuesday. What were your total
earnings? Simplify your answer.
(1 point)
15t – 4
15t + 8
–3t – 4
–3t + 8
Your total earnings are:
6t + 2 + 9t - 6 = 15t - 4
So the correct answer is 15t - 4.
f^2 . f^3
f^2 . f^3 = f^(2+3) = f^5
100^ 12/ 100^8
100^(12/8) = 100^3 = 1,000,000.
Therefore, 100^ (12/8) equals to 1,000,000.
x^16/ x^3
x^(16-3) = x^13
4^4. 4^6
4^4 * 4^6 = 4^(4+6) = 4^10
Therefore, 4^4 * 4^6 equals to 1,048,576.
write the value of expression, 2^3/ 2^3
The expression 2^3/2^3 is equal to 1.
This is because when we have the same base number with exponents being divided, we can directly subtract the exponents:
2^3/2^3 = 2^(3-3) = 2^0
And any number raised to the power of 0 is 1.
3^3/3^6
3^3/3^6 = 1/3^(6-3) = 1/3^3 = 1/27
Therefore, 3^3/3^6 is equal to 1/27.
multiply, write the result in scientific notation, (8. 10^3) (7. 10^5)
To multiply these two numbers in scientific notation, we multiply their coefficients and add their exponents. Therefore:
(8 x 10^3) (7 x 10^5) = (8 x 7) (10^3 x 10^5) = 56 x 10^(3+5) = 56 x 10^8
Since 56 is between 1 and 10, we can rewrite the answer in scientific notation as:
5.6 x 10^9
So, (8 x 10^3) (7 x 10^5) in scientific notation is equal to 5.6 x 10^9.
(2.2 .10^-3)( 4. 10^-2)
To multiply these two numbers in scientific notation, we multiply their coefficients and add their exponents. Therefore:
(2.2 x 10^-3)(4 x 10^-2) = (2.2 x 4) (10^-3 x 10^-2) = 8.8 x 10^-5
So, (2.2 x 10^-3)(4 x 10^-2) in scientific notation is equal to 8.8 x 10^-5.
simplify the expression, 8t^5. 8t^5
To simplify the expression, we can perform the multiplication operation:
8t^5 * 8t^5 = (8 * 8) * (t^5 * t^5) = 64t^(5+5) = 64t^10
Therefore, 8t^5 * 8t^5 simplifies to 64t^10.
-4 (3x + 8)
To simplify the expression, we need to distribute the -4 to each term inside the parentheses:
-4 (3x + 8) = (-4 * 3x) + (-4 * 8) = -12x - 32
So, -4 (3x + 8) simplifies to -12x - 32.
5k^2(-6k^2 - 2k+ 6)
To simplify the expression, we need to distribute 5k^2 to each term inside the parentheses:
5k^2(-6k^2 - 2k + 6) = (5k^2 * -6k^2) + (5k^2 * -2k) + (5k^2 * 6)
= -30k^(2+2) - 10k^(2+1) + 30k^2
= -30k^4 - 10k^3 + 30k^2
Therefore, 5k^2(-6k^2 - 2k + 6) simplifies to -30k^4 - 10k^3 + 30k^2.
(-6x). 7x^2
To simplify the expression, we need to perform the multiplication:
(-6x) * (7x^2) = (-6 * 7) * (x * x^2) = -42x^(1+2) = -42x^3
Therefore, (-6x) * (7x^2) simplifies to -42x^3.
(6y^2 - 4y) + (7y^2-7y)
To simplify the expression, we need to combine like terms by adding the coefficients of same degree terms:
(6y^2 - 4y) + (7y^2 - 7y) = 6y^2 + 7y^2 - 4y - 7y
= (6y^2 + 7y^2) + (-4y - 7y) = 13y^2 - 11y
Therefore, (6y^2 - 4y) + (7y^2 - 7y) simplifies to 13y^2 - 11y.
