Answer:
x=-1
Step-by-step explanation:
2x+6=3-x
Step 1: Simplify both sides of the equation.
2x+6=3−x
2x+6=3+(−x)
2x+6=−x+3
Step 2: Add x to both sides.
2x+6+x=−x+3+x
3x+6=3
Step 3: Subtract 6 from both sides.
3x+6−6=3−6
3x=−3
Step 4: Divide both sides by 3.
3x/3=−3/3
x=−1
Answer:
x=−1
Answer:
A =153.86
Step-by-step explanation:
The diameter is 14
That means the radius is 7
r = d/2 = 14/2 = 7
The area of a circle is
A = pi r^2
A = 3.14 * 7^2
A =153.86
Answer:
matt hgad 12 cookies his 2 other friends came over and divided them equally with them now each of them had four
Step-by-step explanation:
Additive Relationships
(a+b)+c=a+(b+c) associative property of addition
can also be a+b = b+a
Multiplicative Relations
a*(b+c)=ab+ac distributive property of multiplication
a times 1=a identity property of 1
a times 0=0
(a*b)*c=a*(b*c)
I hope this helps!
