3p + 6p = 9p.
It is the same as adding the numbers when you have the same terms (letters).
In this case, it is P.
Hope I helped:)

30. you can model this with an equation and solve, x being the smallest number and the x+1 and x+2 representing the consecutive numbers.
x+(x+1)+(x+2)=93
3x+3=93
3x=90
x=30
x+1=31
x+2=32
30+31+32=93
Simplify brackets
10x - 4 = 8x + 14
Add 4 to both sides
10x = 8x + 14 + 4
Simplify 8x + 14 + 4 to 8x + 18
10x = 8x + 18
Subtract 8x from both sides
10x - 8x = 18
Simplify 10x - 8x to 2x
2x = 18
Divide both sides by 2
x = 18/2
Simplify 18/2 to 9
<u>x = 9</u>
The value of 7 in 3,781 is 10 times greater than the value of 7 in 4,471 the value in the first number is 700 and the value in the second number is 70 so if you were to change 70 into 700 then you would multiply it by 10
Y=4-7x
because it equals = -7
and
y= -5/4x + 2
because it equals = -5/4
