which expression has a value of 30 when x = -1 and y = 3?
Answer:
B. (x - 3²)(y-6)
Step-by-step explanation:
Find the expression with a value of 30;
when x = -1 and y = 3:
A. (x - 3²).y-6
(-1 - 9).3-6 = -10 x 3 -6 = -30 - 6 = -36
B. (x - 3²)(y-6)
( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30
C. x - 3² . (y-6) = -1 - 9.(3-6)
= -1-9.-3
= -1 - 9 x -3
= -1 + 27
= 26
D. x - 3².y-6 = -1 - 9. 3 - 6
= -1 - 27 - 6
= -34

Mr townsend needs to make 13 pairs of butterfly for customers for a play. Each pair of wings is made with 3/4 yard of fabric. The fabric costs $8 per yard.
You’ll apply properties of multiplication in the following steps to find the total cost of fabric.
1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings.
2. Multiply the amount of fabric by the price per yard to find an expression for the total costs.
3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with.

1000000 x 1000000= what?
Answer:
1000000000000
Step-by-step explanation:
1000000x1000000=1000000000000
The solution of the expression 1000000 x 1000000 in exponential form is [tex]10^{12}[/tex].
A collection of constants, variables connected using one or more arithmetic operator is called an expression.
Example = 4y, 3x+4.
The way of writing or expressing a number in powers is called exponent.
Example: [tex]3^2[/tex]
Here, 3 is the base and 3 is the power.
The given expression can be written in the index or exponential form as:
1000000 x 1000000 = [tex]10^6 \times 10^6[/tex]
Since, the given exponent has the same base.
So, using the law of exponent, it can be written as:
[tex]a^m + a^n = a^{(m+n)[/tex]
[tex]10^6 \times 10^6 = 10^{(6+6)}[/tex]
= [tex]10 ^{12}[/tex]
Thus, the solution of the expression 1000000 x 1000000 in exponential form is [tex]10^{12}[/tex].

While eating lunch, Vivian ate 65% of the carrots she had in her bag. There were 20 carrots in her bag before she ate any. How many carrots did Vivian have left in her bag after she ate?
Answer:
Vivian would have 7 carrots left to spare if she ate 65% of the carrots in the bag.
Step-by-step explanation: Since 65% of 20 carrots equals 13 carrots, we would do 20 - 13. In which equals 7 so she has 7 carrots left in fer bag
Equation: 20-x=?
Solution: 20 - 13=7

How do you write (4)(25)-300 as an addition equation
(4)(25) - 300 can be written as an addition equation: 100 + (-300).
What is an equation?An equation is a pair of algebraic equations with the equal sign (=) in the middle and the same value.
Given:
An equation is (4)(25)-300.
To write (4)(25)-300 as an addition equation,
we can break it down into two separate addition equations as follows:
(4)(25) - 300 = (4)(25) + (-300)
To solve this further,
substitute the value 25 x 4 = 100 to the above equation, we get,
= 100 + (-300)
Therefore, the equation in the required form is 100 + (-300).

Which of the following is equivalent to the expression 2 ( 8y + 1/2 ) Select all that apply.
Answer:
B and C both are equivalent to the expression
Answer:
B, C
Step-by-step explanation:
2(8y+1/2) would be equal to 2x8y+2x1/2=16y+1.
2(8y+1/2) would also be equal to 8y+1/2+8y+1/2 because multiplying by 2 is basically just adding the thing you are multiplying to itself.
