Answer:

3

Step-by-step explanation:

We want to cancel out the 3y.  The second equation has a -y so if we multiply that by 3 we'll get -3y and when we add the ys go away.

Answer:

Step-by-step explanation:

Answer:

Multiply the 2nd row by 3.

Step-by-step explanation:

Multiply the second row by 3.  Then we have:

2x + 3y = 18

21x - 3y  = 30

Now, if we combine these two equations, y will disappear and we'll have:

23x = 48, so that

x = 48/23.

Gwar [14]

Answer:

It swims 1.75 miles in 3.5 hours. X stands for hours so x=3.5. Y stands for miles so y=1.75.

Step-by-step explanation:

your equation is y=0.5x

we know x=3.5

so y= 0.5(3.5)

solve and you get y= 1.75

so in (x,y) intercept format (3.5,1.75) and you can make a graph and label your x intercepts hours and your y intercepts miles traveled.

By using parallel lines and transversal lines concept we can prove m∠1=m∠5.

Given that, a║b and both the lines are intersected by transversal t.

We need to prove that m∠1=m∠5.

<h3>What is a transversal?</h3>

In geometry, a transversal is a line that passes through two lines in the same plane at two distinct points.

m∠1+m∠3= 180° (Linear Pair Theorem)

m∠5+m∠6=180° (Linear Pair Theorem)

m∠1+m∠3=m∠5+m∠6

m∠3=m∠6

m∠1=m∠5 (Subtraction Property of Equality)

Hence, proved. By using parallel lines and transversal lines concept we can prove m∠1=m∠5.
