a history teacher is writing a test worth 100 points. She uses multiple-choice questions worth 6 points each and true/false ques

tions worth 2 points each. She wants the test to have three times as many multiple-choice questions as true/false questions. Let m represent the number of multiple-choice questions on the test, and let t represent the number of true/false questions. Which system of equations can be used to find how many of each type of question she should write.

Answer:

6m + 2t = 100

AND

m=3t

solution t=5 m=15

Step-by-step explanation:

6m + 2t = 100 as each m question gives 6 points and each t question gives 2

m=3t as m questions are 3 times t questions

What can each term of the equation be multiplied by to eliminate the fractions before solving? 1/2 x – 5/4 + 2x =5/6 + x
Karo-lina-s [1.5K]

The <u>equation</u>

\dfrac{1}{2}x-\dfrac{5}{4}+2x=\dfrac{5}{6}+x

consists of five <u>terms</u>, three of them contain <u>fractions.</u> The <u>denominators</u> of these fractions are 2, 4 and 6.

Find the LCM(2,4,6). Since

  • 2=2;
  • 4=2·2;
  • 6=2·3,

then LCM(2,4,6)=2·2·3=12.

Thus, you have to multiply each term of the equation by 12 to eliminate the fractions.

Answer: 12

in a population distribution a score of x=28 corresponds to z=-1.00 and a score of x=34 what is the mean and standard deviation
irakobra [83]
x=28\implies z=\dfrac{28-\mu}\sigma\implies \mu-\sigma=28

x=34\implies z=\dfrac{34-\mu}\sigma\implies \mu+\sigma z=34

We need the exact value of z to find a proper solution, but a general one can still be found. Subtracting the first equation from the second gives

(\mu+\sigma z)-(\mu-\sigma)=34-28\implies (z+1)\sigma=6\implies \sigma=\dfrac6{z+1}

Plug this into either equation and you get

\mu-\dfrac6{z+1}=28\implies \mu=28+\dfrac6{z+1}

(It's guaranteed that z\neq-1 in this case because that already corresponds to x=28.)
