Unit price = total price / total quantity:
Main street Market:
Oranges: 3.00 / 5 = 0.60 per pound
Apples: 3.99 / 3 = 1.33 per pound
Off Street Market:
Oranges: 2.59 / 4 = 0.6475 per pound
Apples: 1.98 / 2 = 0.99 per pound
The lower the price per pound the better buy:
Oranges = Main Street Market
Apples = Off Street Market

Answer:
A. 32 = 3x - 5
Step-by-step explanation:
2x-5
2x + x = 3x
3x - 5
32 - 5 = 27
27 divided by 3 = 9
This can be used to find the value of x.
Answer:
C) 32=6x-10
Step-by-step explanation:
As, a perimeter of a rectangle = 2 ( length + breath)
So, 32cm = 2 ( (2x - 5) + x) = 2(2x-5) + 2(x)
= 32cm = 4x - 10 + 2x = 6x - 10
= 32cn = 6x - 10

When a fraction equals zero :
7.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
n+25
———— • 5 = 0 • 5
5
Now, on the left hand side, the 5 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
n+25 = 0
Solving a Single Variable Equation:
7.2 Solve : n+25 = 0
Subtract 25 from both sides of the equation :
n = -25
One solution was found :
n = -25
Answer:
n=-25
Step-by-step explanation:
3/5n+15=10+2/5n

n=-25

what is the answer for 14g > 56?
G > 4
i hope this helps
Answer:
g > 4
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the greater than a sign from both sides of the inequality :
14*g-(56)>0
Pull out like factors :
14g - 56 = 14 • (g - 4)
Divide both sides by 14
Add 4 to both sides
g > 4
Hi just wanted to know if 4/17 is a rational number or not. I think it's irrational because the decimals are unending different sets of numbers and a type of number that can not be put into fraction. But, savemyexams says its a rational number because its decimal is 0.23, but I checked the calculator, unless a characteristic of a rational number is to be able to turn it into decimal.. (but so can pie- 3.14,)
Answer:
4/17 is a rational number
Step-by-step explanation:
It does not matter with the outcome of the fraction for being a rational number or irrational. that is why a fraction before its outcome is a rational number.
Given that,
To determine whether the fraction 4 / 17 is a rational number or an irrational number.
In mathematics, a rational number is a number that can be described as the result of a fraction of value or does not have face value.
What are irrational numbers?An irrational number is a type of real number which cannot be represented as a simple fraction or the values that have face value are irrational numbers. Example: √2, √3, and π are all irrational.
Here,
4 / 17 is a rational number because every fraction, where the numerator and denominator is a natural number is a rational number so we don't, have to divide or perform operations to know whether a fraction is rational or irrational.
4 / 17 = rational number but
4 / 17 = 0.23529441
this 0.2352944 is an irrational number.
Thus, 4 / 17 is a rational number but its outcome is an irrational number.

4v^2 + 8v + 5 = 10 What would I add to this equation to create a perfect square?
Answer:
v₁ = 2.5; v₂ = 0.5.
Step-by-step explanation:
4v² + 8v + 5 = 10
4v² + 8v + 5 - 10 = 10 - 10
4v² + 8v - 5 = 0
D = 8² - 4 · 4 · (-5) = 64 + 80 = 144
[tex]v_{1} =\dfrac{-8-\sqrt{144} }{2 \cdot 4} =\dfrac{-8-12 }{8} =\dfrac{-20}{8} =-2.5\\\\v_{2} =\dfrac{-8+\sqrt{144} }{2 \cdot 4} =\dfrac{-8+12 }{8} =\dfrac{4}{8} =0.5\\\\[/tex]
What is m2+m3?
Pls help ASAP lol
Answer:
ABC has m1 = 90⁰
=> ABC is a right triangle at A
=> m2 + m3 = 90⁰
Answer:
90 degrees
Step-by-step explanation:
Ok so basically, first you see that angle 1 and a right angle are on a line together, and the angles on a straight line always have to add up to 180 degrees. This means that angle 1 = 180-90 = 90.
There's no way to tell the exact angle measure of angle 2 and angle 3, but you can figure out the sum. Since the interior angles of a triangle have to add up to 180, that means that 180 - 90(angle 1) = 90 for the sum of angle 2 and angle 3.

Myra made a scale drawing of an office building. In real life, a desk is 6 feet long. It is 10 inches long in the drawer. What is the scale of the drawing
Answer:
1in : 0.6ft
Step-by-step explanation:
Since the desk is 10 inches in the drawing but 6 feet long in real life then the scale would be 10in : 6ft. This would be the scale of the drawing but we need to simplify it to its most simplest form. We do this by dividing both sides of the scale by 10 so that the left side is equal to 1.
10 / 10 = 1 inch
6 / 10 = 0.6 ft
1in : 0.6ft
Finally, we can see that the scale of the drawing is 1in : 0.6ft

PLEASE HELP MEEE!!
(simplify it)
Answer:
These add up to -5x
Step-by-step explanation:
What you have here is three multiples of x being added and subtracted. Since they are all in the same format (a constant number times x), you can simply add the numbers together.
A potentially easier way to look at it is to think of x as just some type of item. Maybe x is an apple. This means that you are taking -14 apples, subtracting 10 apples, and adding 19 apples.
With that in mind, all you need to do here is take the sum of the numbers, and multiply that by x to get the answer.
[tex]-14x - 10x + 19x\\\\Is\ the\ same\ as\ saying:\\-14 \times x - 10 \times x + 19 \times x\\\\= x(-14 - 10 + 19)\\\\= x \times -5\\= -5x[/tex]

A car purchased in 2014 was worth $21,000. It has depreciated at an annual rate of 8.5%. what will its value be in 2021?
Round answer to the nearest penny (100th)
Answer: The value of the car in 2021 will be $11,276.31.
Step-by-step explanation:
If r is the depreciation rate and P is the initiial amount , then the amount after t years is given by:-
[tex]A=P(1-\dfrac{r}{100})^t[/tex]
Given: P=21000, r=8.5% , t= 2021-2014= 7
Plug all the values in the formula, we get
[tex]A= 21000(1-\dfrac{8.5}{100})^7\\\\\Rightarrow\ A=21000(1-0.085)^7\\\\\Rightarrow\ A= 21000(0.915)^7\\\\\Rightarrow\ A= 21000(0.5369670)\approx11276.31[/tex]
The value of the car in 2021 will be $11,276.31.

Which expressions are equivalent to the given expression?
Please help :(
Answer: -51 - 6*i
Step-by-step explanation:
Remember that if N is a positive number, then:
√(-N) = √N*i
Now we have the equation:
(-√9 + √(-4)) - (2*√576 + √-64)
We can use the first relation and rewrite this as:
(-√9 + √(4)*i) - (2*√576 + √64*i)
Now, all the square roots in the equation are easy ones, like:
√9 = 3
√4 = 2
√64 = 8
√576 = 24
So if we replace these in our equation, we get:
(-3 + 2*i) - (2*24 + 8*i)
-3 + 2*i - 48 - 8*i
Now we group the terms with "i" and the terms without "i"
(-3 - 48) + (2*i - 8*i) = -51 - 6*i
Then the correct option is: -51 - 6*i
