Y=3.25x should be the most probable choice because 6.50 is the price of 2 pounds of candy and once it’s divided by 2 the equation will show how much the unit rate is or the price of each pound of candy.

Which point on the number line best represents√57?

Cerrena [4.2K]

Answer:

Step-by-step explanation:

$\sqrt{57} =\sqrt{3 * 19}$

Since this cannot be further simplified, we will calculate the square root of 57 with our calculators.

We find that the square root of 57 is 7.549834435, and since the tenths place is a 5, we will round up to the next whole number. So, the point on the number line that best represents the square root of 57 is 8.

Hope this helps!

Two parallel lines are crossed by a transversal. If measure of angle 6 is 123.5 then measure of angle 1 is.....

GalinKa [24]

The picture in the attached figure

we know that
m ∠ 6=123.5°

m ∠6+m∠2=180°-------> by supplementary angles
so
m∠2=180-m∠6-----> 180-123.5------> m∠2=56.5°

m∠1=m∠2--------> by corresponding angles
so
m∠1=56.5°

the answer is
m∠1 is 56.5°

Answer: $\bold{b)\quad \dfrac{x-5}{8}}$

<u>Step-by-step explanation:</u>

$y=8x+5\\\\\\\text{Swap the x's and y's. Then solve for y:}\\x=8y+5\\\\\\\text{Subtract 5 from both sides:}\\x-5=8y\\\\\\\text{Divide both sides by 8:}\\\dfrac{x-5}{8}=y$
