If x=9 and y=−3, evaluate the following expression:7(2x−3y)​
LuckyWell [14K]

Answer:

189

Step-by-step explanation:

You can replace the values of x with 9 and the values of y with (-3).

7(2x-3y) = 7(2 × 9 - 3 × -3)

             = 7(18 - -9)

             = 7(18+9)

             = 7 × 27

             = 189

5. Find cos theta if sin theta= -12/13<br> and tan theta &gt; 0. (6 points)
ziro4ka [17]

\text{Given that,}\\\\\sin \theta = -\dfrac{12}{13}\\\\\implies \sin^2 \theta = \dfrac{144}{169}\\\\\implies 1- \cos^2 \theta = \dfrac{144}{169}\\\\\implies \cos^2 \theta = 1- \dfrac{144}{169}\\\\\implies \cos^2 \theta = \dfrac{25}{169}\\\\\implies \cos \theta = \pm \sqrt{\dfrac{25}{169}} = \pm \dfrac 5{13}\\\\\\\text{Since,}~ \tan \theta >0,\\\\\cos \theta =- \dfrac{5}{13}

If 3413 steps=1.27 miles, how many steps equal 1 mile?
sattari [20]
Hi there!

3413 steps = 1.27 miles.
To find the amount of steps in 1 mile, we must divide both sides by 1.27.

3413 / 1.27 steps = 1.27 / 1.27 miles
2687.4 steps = 1 mile.
Hence, in order to walk at least 1 mile, we must take 2688 steps.
