You have $18 to buy peppers. Peppers cost $1.50 each. Write and solve an inequality that represents the numbers of peppers you can buy.
the inequality would be 18>1.5x
this basically means $18 is greater than or equal to 1.5x, where x is the number of peppers you buy at $1.50 for each pepper. So you can buy any amount of peppers from 0 to 12. If you want to make the inequality better it would be 18>1.5x>0 because you can't buy less than 0 peppers
How to simplify 7 - 9x -15 + 12x into an expression
3x - 8
bdjwysksuxvsjahajhx
Answer:
Simplified is 3x - 8
Step-by-step explanation:
First, put the like terms together, so rearrange that equation to 12x - 9x - 15 + 7. Then from there you subtract 9x from 12x which is 2x and add 7 to negative 15, which is -8.

Step-by-step explanation:
Rob can lift less than 135 pounds at the weight room. There is already 48 pounds of weights on the bar. Write an inequality that shows the additional weight that Rob can add, w, without being over his maximum.
Answer:
[tex]x + 46 < 135[/tex]
Step-by-step explanation:
Given
[tex]Initial\ Weight = 48lb[/tex]
He can lift less than 135 implies that, his maximum is:
[tex]Total < 135[/tex]
Required
Determine the additional weight
Let the additional weight be x
Such that
[tex]Total = x + Initial\ Weight[/tex]
[tex]Total = x + 46[/tex]
Substitute x + 46 for Total in [tex]Total < 135[/tex]
[tex]x + 46 < 135[/tex]
Hence, the inequality that describes the scenario is: [tex]x + 46 < 135[/tex]
solve for b and simplify -17=-3/2b
Answer:
b = 34/3
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define equation
-17 = -3/2b
Step 2: Solve for b
Rewrite: -3/2b = -17Divide both sides by -3/2: b = 34/3Step 3: Check
Plug in b to verify it's a solution.
Substitute: -17 = -3/2(34/3)Multiply: -17 = -17find the circumcenter
Answer: (0, -2)

y=100-(1.25)
is it exponential growth or decay ?
what’s the initial value ?
what is the rate of growth or rate of decay ?
Answer:
You should probably double check the problem. The equation you have is just 100-1.25

$200 to spend on the boat rental. The rental is $30 an hour plus a $80 deposit.
How many hours can she rent the pontoon boat for? Create and solve an
equation for this situation.
Answer:
Step-by-step explanation:
She has 200
80 deposit - 200= 120 left to spend
80+30h=200
If she has 120 left to spend at 30 hr, she could have the boat for 4 hrs
80+30h=200 subtract 80 from both sides
30h=120 divide by the 30
h=4
Write an equation that represents the line.
Use exact numbers.
Answer:
y = 5/6x + 2.5
Step-by-step explanation:
slope = m = rise/run
equation format - y=mx+b
slope/m= 5/6
y=5/6x+ the y-intercept
the y-intercept is at 2.5
so the full equation would be \/\/\/
y = 5/6x + 2.5

guys please help/ no answers from google!
it's for tomorrow
Answer:
Length --> x
Width --> y
Perimeter of a rectangle --> 2x + 2y
The length is always 4 cm more than double the width
x - 4 = 2y
y = (x-4)/2
x = 2y + 4
a. The polynomial equation to give the perimeter --> 2(2y+4) + 2((x-4)/2)
b. x - 4 = 2·6 --> x - 4 = 12 --> x = 16
Perimeter --> 2·16 + 2·6 = 44 cm
Jamie buys a ring that is priced at $900. What is the sales price of the ring, if Jamie uses the coupon below?
A.$885
B.$15
C.$765
D.$135
Answer:
D= $135
Step-by-step explanation:
We have to use proportions in order to figure this out. We know that 15% is equal to 15/100.
work:
15/100=x/900.
We cross multiply so its 13,500/100. This is not the answer so we divide which equals to $135

factorise the following:
[tex]{3x}^{2} + 5x - 12[/tex]
Answer:
(x + 3)(3x - 4)
Step-by-step explanation:
Given
3x² + 5x - 12
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 3 × - 12 = - 36 and sum = + 5
The factors are + 9 and - 4
Use these factors to split the x- term
3x² + 9x - 4x - 12 ( factor first/second and third/fourth terms )
= 3x(x + 3) - 4(x + 3) ← factor out (x + 3) from each term
= (x + 3)(3x - 4)
Thus
3x² + 5x - 12 = (x + 3)(3x - 4) ← in factored form

it’s algebra can u helpppp lolsss
Answer:
6z - 6
Step-by-step explanation:
When you expand you are removing brackets. This means you multiply the outer number by the ones inside thus:
2(3z-3)
2 times 3z is 6z .
2 times 3 is 6.
So the answer is 6z - 6.
