Answer:
B) 50º
Step-by-step explanation:
first we need to find angle MPL. to do this we do 180 - 70 - 60 = 50º. angle KPN is the smae as angle MPL. so angle KPN is 50º.
STEP 1:
identify variables and equations
x= larger number
y= smaller number
FIRST EQUATION
x + y= 42
SECOND EQUATION
y= 2x - 63
STEP 2:
substitute the y value in second equation in for y in first equation
x + y= 42
substitute y value from 2nd equation
x + (2x - 63)= 42
combine like terms
3x - 63= 42
add 63 to both sides
3x= 105
divide both sides by 3
x= 35 larger number
STEP 3:
find y value; substitute step 2 x value into either original equation
x + y= 42
35 + y= 42
subtract 35 from both sides
y= 7 smaller number
ANSWER: larger number is x= 35; smaller number is y= 7.
Hope this helps! :)
Answer:
grace by 1 lap.
Step-by-step explanation:
<u>Grace</u><u>.</u>
ran 8 laps
walked 3 laps
<u>Tami</u><u>.</u>
ran 8/2 laps which is 4
walked 3•2 laps which is 6.
add all of them together
Grace has 11 while Tami has 10.
11-10 is 1
73 minus 24 plus 19 gives you 68 people left on the train.
