<span>As you have two fractions, you can cross multiply them. This gives: x/a = y/b to ay = xb. Then divide both sides by b to isolate x: ay/b = x.</span>
Answer:
*see graph below*
Step-by-step explanation:
y = mx + b
m = slope (rise over run)
b = y-intercept
Corresponding with the given equation, the graph below has a y-intercept of 5, and a slope of
or 2.
Answer: 7x + 261
Step-by-step explanation:
(5x + 252 + x + 5) + (x + 4)
5x + 252 + x + 5 + x + 4 (get rid of parenthesis)
7x + 261 (combine like terms)
Answer:
X=26
Step-by-step explanation:
180-105=75
26•2=52. 52+23=75°
Answer:
The least number of stamps required is 
Step-by-step explanation:
Let the number of
cent stamps be
and
cent stamps be 
We have

The minimum number is obtained when more
cent stamps are used
Here
cannot be greater than
since 
Substitute 

Not possible since
is not a fraction
Substitute 

Not possible since
is not a fraction
Substitute 

Possible
Hence minimum number of stamps is
