Answer:
B) 2(x+3)(x+3)
Step-by-step explanation:
Answer: 12
Step-by-step explanation:
18÷3=6
6+6=12
18+12=30
30-18=12
Step-by-step explanation:
again, a line cutting through 2 parallel lines must have the exact same angles with both of them. otherwise they would not be parallel.
therefore, both angles must be identical
3x + 2 = 2x + 6
x = 4
Answer:
Step-by-step explanation:
Given
Required
Determine the equation
First, we calculate the intercepts using:
Where
b = Intercept on y axis.
a = Intercept on x axis.
From the question:
The equation becomes:
Multiply through by 3b
We have:
So:
Make b the subject
Substitute in to get the equation
Make 3y the subject
Make y the subject
Make 2 eqn, let a be apples and o be oranges:
1. 5a + 4o = 10
2. 5a + 5o = 11
set up an elimination:
1. minus 2.
5a + 4o = 10
- 5a + 5o = 11
____________
o = 1
sub “o” into one of the eqn
5a + 5(1) = 11
5a = 11-5
5a = 6
a = 6/5
a = 1.2
therefore, an orange costs $1.00 and an apple costs $1.20
