Explanation:
Divide both sides by -2 to isolate x.
Since you have divided by a negative number and it changed the positive number to a negative one, you'll need to change the direction of the sign to now reflect that.

How do you decide whether the larger unit rate or the smaller unit rate is the better buy? Please help me.
Answer:
The smaller unit rate is a better buy
Step-by-step explanation:
Given
Larger unit rates and smaller unit rates
Required
Determine which is a better buy
To answer this, I'll use the following assumptions.
If store A and store B sell the same product at $2/ unit and $3/ per unit respectively.
At store A (with $2/unit), you will get 50 of that product at 50 * 2 = $100
At store B (with $3/unit), you will get 50 of that product at 50 * 2 = $150
Meaning that, you will spend more at the store with the larger unit rate (and you don't want that, do you?)
Hence, the smaller unit rate is a better buy.

What is −3/4x−1/3+7/8x−1/2 written in simplest form?
Answer:
I love algebra anyways
The ans is in the picture with the steps how i got it
(hope this helps can i plz have brainlist :D hehe)
Step-by-step explanation:
The simplest form of expression - 3/4x - 1/3 + 7/8x - 1/2 is,
⇒ x/8 - 5/6
The given expression is,
⇒ - 3/4x - 1/3 + 7/8x - 1/2
Now, We can simplify the expression by combining like terms as,
⇒ - 3/4x - 1/3 + 7/8x - 1/2
⇒ - 3/4 x + 7/8x - 1/3 - 1/2
⇒ - 6/8x + 7/8x - 1/3 - 1/2
⇒ (- 6 + 7)x/8 - (1/3 + 1/2)
⇒ x/8 - (3 + 2)/6
⇒ x/8 - 5/6
Therefore, The simplest form of expression - 3/4x - 1/3 + 7/8x - 1/2 is,
⇒ x/8 - 5/6

Factorise x cubed - x
Answer:
= x(x+1)(x-1)
Step-by-step explanation:
Given the expression x³ - x
On factorizing
x³ - x
= x(x²-1)
Using difference of two square
a² - b² = (a+b) (a-b)
x² - 1
= x² - 1²
= (x+1)(x-1)
The complete factor
x³ - x
= x(x²-1)

O 3(3-1)
O 9(y-3)
O 9(3y-3)
Answer:
3(3y-1)
Step-by-step explanation:
To find out which expression is equivalent, expand and simplify the options listed to see which one equals 9y-3.
Let's try the second option. To simplify the expression, use the distributive property. So, multiply each term in the parentheses by 3:
[tex]3(3y-1)\\= 9y-3[/tex]

During a scuba dive, Lainey descended to a point 23 feet below the ocean surface. She continued her
descent at a rate of 23 feet per minute. Enter an inequality you could solve to find the number of minutes
she can continue to descend if she does not want to reach a point more than 97 feet below the ocean
surface. Use t to represent the variable for the minutes Lainey can continue to descend.
The inequality is
t (select)
t (23) ≤ 97 - 23
The minus 23 at the back represents the feet she already descended before what the question wants us to calculate
≤ is used instead of < because it states more than, not "equal or more than" (meaning 97 sharp is fine)
Ruchi travelled 149 cm 415 in a week How much distance did she travel in a day
Answer:
171.85 cm
Step-by-step explanation:
Given data
We are given that the distance = 149 cm 415in
Let us mark the units uniform by converting inches to cm
1 inches = 2.54cm
415 inches= x cm
cross multiply
x= 415*2.54
x= 1054.1 cm
Hence the total distance in cm is 1054.1+149= 1203cm
If in 7 days he travels 1203cm
in 1 day he will travel x cm
cross multiply
7x= 1203
divide both sides by 7
x= 1203/7
x= 171.85 cm

The diagram shows a trapezium.
x-4
Diagram NOT
accurately drawn
2x
x + 5
All the measurements are in centimetres.
The area of the trapezium is 351 cm2.
(a) Show that 2x2 + x - 351 = 0
Answer:
Step-by-step explanation:
The area of a trapezium is given as;
Area = [tex]\frac{1}{2}[/tex](a + b)h
where: a is the length of the upper side, b is the length of its base and h is its height.
This implies that; a = x - 4, b = x + 5, h = 2x and area = 351
Thus,
351 = [tex]\frac{1}{2}[/tex]((x - 4) + (x + 50)) 2x
= (x - 4 + x + 5) x
531 = (2x + 1) x
= 2[tex]x^{2}[/tex] + x
So that;
2[tex]x^{2}[/tex] + x - 531 = 0
This gives a quadratic equation.
