Answer:
Emily is 17
Step-by-step explanation:
If Jamie is 47 and she is 4 less than 3 times older than Emily, you want to start by doing the opposite of each identifying word. Remember to work backwards. 4 less means minus 4, but you want to do the opposite so you will add 4 to 47. 47 + 4 = 51 Then if it says 3 times this mean multiplication but again, we wanna do the opposite so 51 ÷ 3 = 17
To check it Multiply 17 by 3 and then subtract 4. 17*3=51 51-4=47

Answer:
x=48 degrees
Step-by-step explanation:
to find the right most angle you do 180-140=40 because supplementary angles. you then add that to 92. that equals 132 degrees. you then subtract 132 from 180 becuse total angles in a triangle is equal to 180 degrees. this is why the answer is 48 degrees. hope this helped.:)
Answer:
x=5
Step-by-step explanation:
add 3 to both sides of the equation: -3+3=0 12+3=15 simplified: 6x=3x+15 then subtract 3x from both sides of the equation. simplified: 3x=15
then divide both sides by 3. simplified: x=5
