The simplest way to do this is to set up equivalent fractions. So, you'd do:
= 
and then solve for x.
x=52
x=52

Answer:
Both questions are true.
Step-by-step explanation:
The general mathematical equation of a line can be written as .
If we rearrange the two equations given in the question as follows:
and
We can see that they follow the general equation we defined earlier so we can say that they represents linear lines.
The given in the second question also represents a similar linear line with a different slope.
So the two questions are both true.
I hope this answer helps.
The coffee shop used 52 pounds of Type A coffee.
Step-by-step explanation:
Cost of Type A coffee per pound = 5.25
Cost of Type B coffee per pound = 4.10
Total pounds used in blend = 142
Total cost = 642.00
Let,
x be the pounds of Type A coffee used
y be the pounds of Type B coffee used
According to given statement;
x+y=142 Eqn 1
5.25x+4.10y=642.00 Eqn 2
Multiplying Eqn 1 by 4.10
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 1.15
The coffee shop used 52 pounds of Type A coffee.
