Step-by-step explanation:
(9x-8)-(x+4)=8x+12
9x-8-x-4=8x+12
8x-12=8x+12 (no it's not)
So it's false.
Hey guys! I need help with this question urgently, so could you please help me out? Thanks in advance! Merry Christmas!

Answer:
336x + 624
Step-by-step explanation:
The area of a circle is A = πr^2. We let A1 And A2 the areas of the circles and r1 and r2 the radius of each, respectivley.
A1 + A2 = 80π
Substitute the formula for the area,
π(r1)^2 + π (r2)^2 = 80π
From the statement, we know that r2=2(r1).
<span>π(r1)^2 + π (2 x r1)^2 = 80π
</span>We can cancel π, we will have
5 x (r1)^2 = 80
Thus,
r1 = 4 and r2 = 8
Answer:
$91/$15=x
Step-by-step explanation:
$100-$9=$91 and 91÷15= 6. omething which means only 6 pizza can be purchased.
The answer up above just says 91 divided by 15 gives you the amount of pizzas. He can only buy 6 pizzas with a pound remainding
−3(1+x)=−3x+1
Step 1: Simplify both sides of the equation.
−3(1+x)=−3x+1
(−3)(1)+(-3)(X)=-3x+1
(Distribute)
−3+ −3x=−3x+1
−3x−3=−3x+1
Step 2: Add 3x to both sides.
−3x−3+3x=-3x+1+3x
−3=1
Step 3: Add 3 to both sides.
−3+3=1+3
0=4
Answer:
There are no solutions.
