-⅔ (6x +9) = 18 I really need some help and understanding with this one. Thanks in advance!!
-⅔ (6x + 9) = 18
Apply distributive property. Multipy -⅔ to 6x and 9.
-4x - 6 = 18
Add 6 to both sides so -4x can be alone.
-4x - 6 + 6 = 18 + 6
-4x = 24
To get x alone, divide both sides by -4.
-4/-4x = 24/-4
x = -6
x = -6 is your answer. I hope this helps! Let me know if you need more help or if I got something wrong.

4.1271 to the nearest cent?!
Answer:
4.1271
Step-by-step explanation:
Look at the number to the right of the full cents, if the number is five or more, increase the cents by 1. If the number is four or less, keep the cents the same. For example: Round $143.864. Look at the last digit, that is 4, since 4 is less than 5 so keep cents the same.
4.1271
last number is 1 so the cents stays the same
Identify the conclusion of the statement.
If 2n-7 > 25, then n > 16
1- 2n-7 > 25
2- n > 16
3- 2n > 32
4- no conclusion can be made
Answer:
2) n > 16
Step-by-step explanation:
Usually, a statement is written as:
If P, then Q
Where P = hypothesis
Q = conclusion.
And our statement is:
if 2n - 7 > 25, then n > 16
(We can easily solve the inequality to get the thing in the right:
2n - 7 > 25
2n > 25 + 7 = 32
n > 32/2 = 16
n > 16 )
then:
P = (2n - 7)
Q = n > 16
Then the conclusion is: n > 16
The correct option is 2) n > 16

find the gradient of lines A and B
Answer:
Line A Gradient: 2
Lime B Gradient: -1
Step-by-step explanation:
✔️Gradient for line A using two points on line A, (0, 1) and (1, 3):
[tex] Gradient = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 - 1}{1 - 0} = \frac{2}{1} = 2 [/tex]
Gradient of line A = 2
✔️Gradient for line B using two points on line B, (5, 0) and (3, 2):
[tex] Gradient = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 0}{3 - 5} = \frac{2}{-2} = -1 [/tex]
Gradient of line B = -1

Annie decided to build a fence around her 15 ft long rectangular flowerbed. How many feet of fencing should she buy if the width of the flowerbed is 4/5 the length?
Answer:
54 ft
Step-by-step explanation:
Length of the rectangular flowerbed = 15 ft
Width of the rectangular flowerbed = 4/5 of the length
= 4/5 × 15
= (4*15)/5
= 60/5
= 12
Width of the rectangular flowerbed = 12 ft
How many feet of fencing should she buy
Perimeter of the rectangular flowerbed = 2(length + width)
= 2(15ft + 12ft)
= 2(27ft)
= 54 ft
Perimeter of the rectangular flowerbed = 54 ft
She should buy 54 ft of fencing
6x2 + 6x – 1= -5x – 4
Answer:
x= -1/3 or x= -3/3
Step-by-step explanation:
Let's solve your equation step-by-step.
6x2+6x−1=−5x−4
Step 1: Subtract -5x-4 from both sides.
6x2+6x−1−(−5x−4)=−5x−4−(−5x−4)
6x2+11x+3=0
Step 2: Factor left side of equation.
(3x+1)(2x+3)=0
Step 3: Set factors equal to 0.
3x+1=0 or 2x+3=0

A proportion is an equation in which two ratios are set equal to each other. Then the value of 1 unit is 1.375.
What is a ratio?
A ratio is an ordered couple of numbers a and b, written as a/b where b can not equal 0.
The value of 8 units is 11.
Then the value of 1 unit will be
The value of 8 units is 11.

A company receives different types of objects and typically receives 75 new objects on average each month. The company currently has 210
objects in stock, which have a variety of properties. Write
an algebraic equation that describes the relationship between the number of
additional months the company receives objects (m) and the total number of objects in the company (t).
Fill in the blank for
Answer: t= 75m+210
Step-by-step explanation:
Linear equation: y= nx+c
, where n =rate of change of y with respect to x, c= initial value of y
Let m= number of additional months the company receives objects .
t =total number of objects in the company.
Given: Number of objects received per month = 75. (Rate of change of t w.r.t. m)
Current number of objects = 210 (Initial value)
Then, t= 75m+210
Hence, the required algebraic equation: t= 75m+210

Do you knows the product of a number and four is 1.08. He says the other factor must be 2.7 because there's only one digit before the decimal point in the product 1.08, so, there must be one digit before the decimal in the factor. Is drew correct
Answer:
Drew is incorrect
Step-by-step explanation:
Drew is incorrect
Let the number be x such that if the product of the number and four is 1.08 then
x * 4 = 1.08
Divide both sides by 4
x = 1.08/4
= 0.27
Drew is incorrect because the result (1.08) has 2 decimal places and not once as deduced by him hence the number of digits before the decimal point for the numbers being multiplied must be 2.
