20yz/28xyz simplify.
Answer:
5/7X
Step-by-step explanation:
cancel Y and Z from both sides
get the HCF (highest common factor) between 20 and 28 which is 4
then divide both sides with 4
the final answer will be:
5/7X

Answer:
7/10
Step-by-step explanation:
1/10 = 2/20
1/4 = 5/20
2/5 = 8/20
11/20 = 11/20
We can see that the next term is just 11/20 + 3/20, as 3/20 is added onto each of the next terms.
11/20 + 3/20 = 14/20, which can be simplified to 7/10.
Hope this helps!

The sum of three consecutive numbers is
42. Find the largest number in the set
Answer:
20
Step-by-step explanation:
Well consecutive numbers mean that the 3 numbers will follow each other in smallest to largest.
Example : 6, 7, 8 or 6,34,87
Non-Example : 7, 9, 6
As long as the number is greater than the one before it they are consecutive.
Following this rule I have come up with the numbers :
10, 12, 20
These three numbers are consecutive and equal to 42.
Now to find the largest number in this set just look at the greatest value which would be 20.
I don't have an entire explanation for this as I just did it in my head but I do hope it is correct.
I hope this helps! :)
Ms. Rios mowed
2
7
of her lawn. Her son mowed
1
4
of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
Answer:
Ms Rios mowed more
Step-by-step explanation:
I'm assuming that there's 100% of the lawn so if Ms Rios mowed 27% of the lawn when it was at 100% it would be at 73%
Now if her son mowed 14% and it was still at 100% it would be at 86%
So in the end Ms Rios mowed more of her lawn

11) Elsa took out a $2,200 loan with a 2-year term to buy a car at a 6% simple interest rate. How much will she have to pay IN INTEREST? *
Answer:
$264
Step-by-step explanation:
A 6% interest means that you have to pay 6% of the loan every period (which in this case is a year because it isn't stated anywhere). 6% of $2.200 is equal to $132, so for a loan of 2 years Elsa has to pay [tex]\$132 \cdot 2 = \$264[/tex], which is exactly what the question was asking for.
Maia says that the lines in this system of linear eqations are parallel. is she correct? explain.
2x+y=14
2y+4x=14
Answer:
yes, they are parallel because their slopes are the same
Step-by-step explanation:
if you put each equation into slope-intercept form and compare slopes you can see whether they are parallel or not
2x + y = 14
y = -2x + 14
slope = -2
2y + 4x = 14
2y = -4x + 14
slope = -4/2, which simplifies to be -2

Answer:
[tex]\sqrt{3}[/tex]
Step-by-step explanation:
See attachment 1. This is the formula to use.
There are two numbers, so n=2. Plugging them into the formula, you get
[tex]\sqrt[2]{6*\frac{1}{2}} \\[/tex]
Now, putting a 2 in front just means we're finding the square root, so I'll get rid of it. Then, just do the calculation.
[tex]\sqrt{6*\frac{1}{2}}=\sqrt{\frac{6}{2}}=\sqrt{3}[/tex]
Answer:
√3
Step-by-step explanation:
To find the Geometric mean, multiply the values given, then take the square root.
x² = ab
x= √ab
It's a "central tendency" we are calculating.
This is different from the arithmetical mean which uses addition and division to find that average.

It is not.
Step-by-step explanation:
The formula of a right triangle is "[tex]a^{2}+b^{2} =c^{2}[/tex]" where c is the hypothenuse (the longest side of the triangle) if we replace the formula with the values we will get

The regular price of a stereo system at Best Buy is $375. The system is on sale for 15% off the
regular price. The sales tax rate is 6%. What is the final cost of the stereo system, after the
discount and including the tax? *
$229.62
$318.75
$341.25
$337.88
The final cost of the stereo system after the discount and including the tax is $337.88. The correct option is D.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the regular price of a stereo system at Best Buy is $375. The system is on sale for 15% off the regular price. The sales tax rate is 6%.
The discounted price is calculated as,
Discounted Price = 375 x 0.85
Discounted Price = 318.75
The total price after sales tax is,
Total price = 318.75 x 1.06
Total price = $337.875
