Answer:
Step-by-step explanation:
<h2>4/x=2/10</h2>
cross multiplication:
4*10=2*x
40=2x
x=40/2=20
<h2>w/2 = 4.5/6.8</h2>
6.8w=2(4.5)
6.8w=9
w=9/6.8=1.32352941
Answer:
x-2y/x
Step-by-step explanation:
x²-4xy+4y²/x²+xy-6y²÷x²+3xy/x²+6xy+9y² = x-2y/x
Answer:
x≥2
Step-by-step explanation:
Let's solve your inequality step-by-step.
12−7x≤−2
Step 1: Simplify both sides of the inequality.
−7x+12≤−2
Step 2: Subtract 12 from both sides.
−7x+12−12≤−2−12
−7x≤−14
Step 3: Divide both sides by -7.
−7x/−7 ≤ −14/−7
x≥2
Whenever you solve an equation with a single variable you need to isolate the variable by itself on one side of the equal sign. Just be sure that whatever operations you perform on one side you perform on the other sides as well.
62x=1 divide both sides by 62
x=1/62
Answer: 4x² + 12x + 9
Explanation:
Area = (2x + 3) (2x + 3) = 4x² + 6x + 6x + 9 = 4x² + 12x + 9
