Answer:
The width is 8
Step-by-step explanation:
if the ratio of length to width is 9 to 4. and we know the length is 18, 18 is 2 times as much as 9, so 4*2=8. 9*2=18,4*2=8
Answer:
x = 11/9
Step-by-step explanation:
Eliminate parentheses, add 16x, subtract 21.
7(3 -x) = 8(4 -2x) . . . . given
21 -7x = 32 -16x . . . . . eliminate parentheses using the distributive property
9x +21 = 32 . . . . . . . . add 16x
9x = 11 . . . . . . . . . . . . subtract 21
x = 11/9 . . . . . . . . . . . .divide by the coefficient of x
Step-by-step explanation:

Distribute into 5x² into (3x +2).

The simplified expression is <em>15x³ + 10x²</em>
Answer:
Y=2x-3/4
Step-by-step explanation:
1) put all the information you have in Y=mx+b form
2) y=2x-3/4
2 is the slope and -3/4 is the y intercept
1- Let's solve the numerator Inside the bracket m⁻¹.m⁵ =m⁽⁻¹⁺⁵⁾ =m⁽⁴⁾
2- numerator/denominator = m⁽⁴⁾ / m⁻² = m⁽⁴⁾⁻⁽⁻²⁾ =m⁶
3- Now let' include it in the parenthesis:[ m⁶]⁻³ =m⁻¹⁸ =1/m¹⁸<u />
