Answer:
31
Step-by-step explanation:
First of,
or, in probability is subtraction and not means you shouldn't use green (therefore leaving you with yellow and red)
Red = 42
Yellow = 20
P(Yellow or Not Green) = 
⁘ 
= 
Hence, 31
Answer:
4 pencil & 2 ruler = $8
2 pencil & 4 ruler = $10
let the no. of Pencil be X and no. of ruler be Y
4x + 2y = 8
2x + 4y= 10
solving the equation by elimination method,
multiplying eq 2 with 2
4x + 2y = 8
4x + 8y = 20
subtracting,
- 6 y = -12
y = 2
2x + 4(2)= 10
2x + 8 = 10
2x = 10 - 8
2x = 2
x = 1
Cost of 3 ruler + 3 pencil
= 3(1) + 3(2)
= 3 + 6
= 9
<h2 /><h2>= $9</h2>
The function given is:
h(x) = 3x-19
we want to find the value of x that makes this function equal to 71. To do so, we will substitute h(x) with 71 and solve for x as follows:
h(x) = 3x - 19
71 = 3x - 19
3x = 71+19
3x = 90
x = 90/3 = 30
Angles p and w are on opposite sides of the transversal, so are "opposite." The are between the parallel lines, so are "interior."
The appropriate selection is ...
... C. alternate interior angles

First find the LCM which is 6 so multiply 
by 3 to get 
and multiply 
by 2 to get 
and then add 
I can try to explain how to get LCM if you don't know how
I'm bad at explaining things but I tried :/
