(100-15)% = 85% = 136 students
136 / (85%) = 130*(100/85) = 160 students
There are 7 nickels and 8 dimes, if you look closely at the procedure, you can see how <em>x </em>is established for the nickels (0.05) and <em>y </em>for the dimes (0.10).
2/3 divided by 8/9 is 3/4
Answer:
- 1
Step-by-step explanation:
The product of the slopes of lines perpendicular to each other is - 1
Given y = 4x - 5 with slope 4
y = - 
x - 5 with slope - then
4 × - = - 1 proving the lines are perpendicular
Answer:
8
Step-by-step explanation:
A = l*w
A = (2x-3) (4x+1)
FOIL
A = 2x*4x+2x*1-3*4x-3*1
=8x^2 +2x-12x-3
= 8x^2-10x-3
The coefficient of the x^2 term is 8
