12v = 18+6v
move +6v to the other side
sign changes from +6v to -6v
12v-6v= 18+6v-6v
12v-6v= 18
6v= 18
divide by 6 to get v by itself
6v/6=18/6
Answer:
v= 3
Answer:
Step-by-step explanation:
-3x - 5 = 16
add 5 to both sides of the equation
-3x = 21
divide both sides by -3
x = -7
---------------------
-4(y - 2) = 12
distribute the -4 to everything in the parentheses
-4y + 8 = 12
subtract 8 from both sides of the equation
-4y = 4
divide both sides of the equation by -4
y = -1
For the 6 friends to eat a half meat pie the will eat 3 and they will be 2 more, the 6 friends should cut each one into 3 half's.
We first write the word in math as x+3/5 = 5/7. Now we cross multiply our fractions and rewrite them with the LCD of 5 and 7. Our equation now looks like x + 21/35 = 25/35. We simplify our equation by subtracting 21/35 from both sides to get x = 4/35. 4/35 is already in lowest terms so it is our answer.
Answer:
well if you're looking for angles then
angle ADB = 30°
angle CBD = 80°
angle CDB = 120°
but they asked to classify triangle ADC ,whose measurements are 90° , 40° and 50° ...so of they're asking what type of triangle then it is a right angled triangle.
