It's a. 3.
because
3+6x=21
6x=18
x=3.
They get 60 dollars each Sarah and Mary and John gets 30 dollars because 60+60=120 and add 30 and it is 150 and 30 is half of 60
Answer:
157 Inches
Step-by-step explanation:
Since the diameter is 2 times the length of the radius, it would be 157 if you multiply 78.5 by 2.
Answer:
2⋅2⋅2⋅5=40 2 ⋅ 2 ⋅ 2 ⋅ 5 = 40
Answer:
x= 1/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1x+3=x+10x−2
x+3=x+10x+−2
x+3=(x+10x)+(−2)(Combine Like Terms)
x+3=11x+−2
x+3=11x−2
Step 2: Subtract 11x from both sides.
x+3−11x=11x−2−11x
−10x+3=−2
Step 3: Subtract 3 from both sides.
−10x+3−3=−2−3
−10x=−5
Step 4: Divide both sides by -10.
−10x/−10=−5/−10x=1/2
