Answer:
C) 3x - 6
Step-by-step explanation:
Let the unknown number be represented by placeholder x.
Then the product of 3 and the number is represented by 3*x or 3x.
This value diminished by 6 corresponds to 3x-6.
So the expression representing the required overall construct mathematically is given by 3x-6
Option a, 6x-3 represents the difference of 6 times x and 3.
Option b, 3-6x represents the difference of 3 and (6 times x).
Option d, 6-3x represents the difference of 6 and (3 times x).
Answer: um, you mean 10 + 122=132, the second one is n>4 if you want step by step look below:
Let's solve your inequality step-by-step.
3n>12
Step 1: Divide both sides by 3.
3n/3 > 12/3
n>4
You can use a numberline too.
Answer:
what do you need help on
Step-by-step explanation:
what
X= # of residents
y= # of non residents
QUANITY EQUATION
x+y= 58
COST EQUATION
$13.00x + $17.50y= $925.00
SOLVE FOR 1 VARIABLE
x+y= 58
subtract y from both sides
x= 58-y
SUBSTITUTE IN 2nd EQUATION
$13.00x + $17.50= $925.00
13(58-y) + 17.50y= 925.00
multiply 13 by all in parentheses
(13*58)+(13*-y)+17.50y= 925.00
754-13y+17.50y= 925.00
combine like terms
754+4.50y= 925.00
subtract both sides by 754
4.50y= 171
divide both sides by 4.50
y= 38 number of non residents
SUBSTITUTE TO FIND X
x+y= 58
x+38= 58
x= 20 number of residents
ANSWER: 20 residents and 38 non residents attended.
CHECK:
$13.00(20) + $17.50(38)= $925.00
260 + 665= 925
925 = 925
Hope this helps! :)
No, It’s not a right triangle.
We can prove by using Pythagoras theorem
Let the longest length be hypotenuse and shortest length be base now,
h^2=p^2+b^2
16^2=13^2+8^2
256=169+64
246=233
Hence it is not equal with hypotenuse
In right triangle the sum of the squares of two short sides should be equal to hypotenuse
