Answer:
y= 3x
Step-by-step explanation:
This is honestly your basic times tables if we are being honest. We know that she read 3 paragraphs per minute. We also know that in 4 minutes, she read 12 paragraphs. 4 times 3 = 12. So the answer is y=3x.
Answer:
3x + 6 or 3( x + 2 )
Step-by-step explanation:
5x - 2x = 3x
4 + 2 = 6

Answer:
A=81
Step-by-step explanation:
the first bullet is harder, but stuff you'll need to know eventually. The second bullet is SUPER simple.
a²+b²=c².
- One way you can do it; we know that c²=225, so find the square root of that. (it's 15). we also know that either a² or b² is 144. so now we square root that. (its 12). so we know that 15²-12²=b². or that 15²-12²=b². it doesn't matter if it's a or b. pick whichever one you want. plug one if the equations in, and you'll get 81.
- Second way you can do it, which is easier. 225-144=81. this is the same as above, but skipping steps. good for simple math, but later on with harder math it might make things confusing.
