Answer:
Step-by-step explanation:
We'll call the 2 numbers x and y. Starting with the last part of that first sentence "one number is 10 times the other number" can be written, in algebraic form:
y = 10x
Now on to the first statement about the numbers: "twice their sum" is 2(x + y) and "equals their product" is = xy. Putting that all together:
2(x + y) = xy and we know that y = 10x so
2(x + 10x) = x(10x) and
and
and
x(10x - 22) = 0 so
x = 0 or 10x - 22 = 0 which makes
x equal to 
So x = 2.2 and y = 22.
Answer:
Yes.
Step-by-step explanation:
By adding like terms, -x - 2x = -3x. Therefore, they are equivalent.
Answer:
0.55
Step-by-step explanation:
diference= 25/100*2.20=0.55
Im not technically sure whate it would be but i would imprevise by saying you can save up u can also put more effort to work
Answer:

Step-by-step explanation:
First write the problem out as a fraction.

Next see if there is a GCF
4:1,2,4
16:1,2,4,8,16
Finally divide the numerator and denomenator by the GCF
