Answer:
77x+33y
Step-by-step explanation:
Eliminate redundant parentheses
(33x+53y)+(44x−20y)
33+53+44−20
Combine like terms
33x+53y+44x−20y
77+53−20
Combine like terms
77x+53y−20y
77+33
Solution:
77+33
Answer:
y = 2x+7
Step-by-step explanation:
This is equation is in the form
y= mx+b where m is the slope and b is the y intercept
y =2x + ? means we are looking for the y intercept which is the value of y when x is zero
From the table, x=0 and y=7
y = 2x+7
Answer:
using cos=adjacent/hypotenuse
Step-by-step explanation:
in this case cos(60)=x/4√3
x=cos(60)*4√3
x=3.46
Answer:
The number is 5.
Step-by-step explanation:
The product of 5 and 4 more than a number = 9 times the number
Let the number be x;
5(4 + x) = 9x
20 + 5x = 9x
4x = 20
x = 20/5
x = 5.
