Elena L [17]

Answer:

x=4 y=0

Step-by-step explanation:

3x+5y=12

-(x-3y=4)

14y=0

y=0

Then, substitute the y into the equation to find x

x-3(0)=4

x=4

Question 11

dem82 [27]

Answer:

There were 49 questions on this Geometry test.

Step-by-step explanation:

You can start by setting up a proportion:

x = total number of questions on Geometry test

$\frac{37}{x}$ = $\frac{75.51}{100}$

Now, to solve for x, cross multiply:

75.51x = 3700

Finally, isolate x and solve:

x = 49.0001324328

This is very close to 49.
