Answer:
Step-by-step explanation:
12x+3y= 15
12x= -3y+15
divide both sides by 12 and you get
x= -3/12y+15/12
simplifying:
x=-1/4+5/4
A=25m2, b= _, h= 5/6m
Area of a triangle = 1/2 x b x h
25 = 1/2 x b x 5/6
Divide both sides by1/2
50 = b x 5/6
Divide both sides by 5/6
b = 60m

You do not really have to simplify a fraction
Answer:
Check if the denominator has any radicals. If so, multiply both numerator and denominator with the radical to remove it.Check if the numerator and denominator have any common factors. If so, factor them out and remove them.Check if the numerator is greater than the denominator. If so, change fraction into a mixed number.Step-by-step explanation:

[tex]17x - 18 = 2(7x)[/tex]
Answer:
x = 6Explanation:
17x − 18 = 2(7x)
Simplify both sides of the equation17x − 18 = 2(7x)
17x + −18 = 14x
17x − 18 = 14x
Subtract 14x from both sides17x − 18 − 14x = 14x − 14x
3x − 18 = 0
Add 18 to both sides3x − 18 + 18 = 0 + 18
3x = 18
Divide both sides by 33x / 3 = 18 / 3

Emeka is 10 years 6 months old and his classmate Boyle is 9 years old find the ratio of their age
Answer:
Hi...
10+6/12=10.5
So...10.5/9=1.16
The ratio shows how many times one value is contained in another value.
Emeka's age = 10.5 years
Boyle's age = 9 years
The ratio of Emeka's age and Boyle's age is 7/6.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
Emeka:
Age = 10 years and 6 months
We know that,
12 months = 1 year
Divide 6 on both sides.
6 months = 1/6 years
6 months = 0.5 years
So,
10 years and 6 months = 10.5 years.
Emeka age = 10.5 years _____(1)
Boyle:
Age = 9 years _____(2)
The ratio of Emeka's age and Boyle's age.
From (1) and (2) we get,
= Emeka age : Boyle age
= 10.5 : 9
= 105 / 90
= 5 x 21 / 5 x 18
= 21 / 18
= 3 x 7 / 3 x 6
= 7/6
Thus,
The ratio of Emeka's age and Boyle's age is 7/6.

Find the 4th term in the sequence with the following definition:
A1= 0
An=2 (an-1 -3)
Answer:
A2=2(a2-1-3)
A2=2(a1-3)
A2=2(0-3)
A2=-6
A3=2(a2-3)
A3=2(-6-3)
A3=2*-9
A3=-18
A4=2(a3-3)
A4=2(-18-3)
A4=-42
The 4th term in the sequence using the given definition is -42.
for better understanding check the calcualtion below .
Calculation :
we find out the fourth term in the sequence by using the given formula
Given :
[tex]a_1=0\\a_n=2(a_{n-1}-3)[/tex]
first term is given as 0
Lets find out the second term using the given formula
Substitute n =1 to find out second term
[tex]a_n=2(a_{n-1}-3)\\n=2\\ a_2=2(a_{2-1}-3)\\ a_2=2(a_{1}-3)\\a_2=2(0-3)\\a_2=-6[/tex]
so the second term is -6
Find out thrid term by substituting n = 3
[tex]a_3=2(a_2-3)\\a_3=2(-6-3)\\a_3=-18[/tex]
So the third term is -18 . Now find out fourth term by substituting 4 for n
[tex]a_4=2(a_3-3)\\a_4=2(-18-3)\\a_4=-42[/tex]
The 4th term in the sequence using the given definition is -42

What is f(3)??????????
f(a) means the value of f(x) is ... when x = a. That means if we substitute x = 3, we would get f(3).
f(3) also means the value of f(x) is ... when x = 3.
f(x) can also be defined as y // f(x) = y
Find f(3) by graph.You can find the value of f(x) at specific domain from the graph by looking at x = 3 then look up to where the point or where the graph passes. From the graph, when x = 3 as we look up and the graph passes y-coordinate at 1.
Therefore we can say that when x = 3, y = 1.
Answerf(3) = 1
