Step-by-step explanation:
when we simplify the original expression, we can combine the y parts and the x parts - remember multiplying with exponents means adding the exponents.
so,
y^-8 × y^3 = y^(-8 + 3) = y^-5
x^0 × x^-2 = x^(0 - 2) = x^-2
therefore, the main expression is actually
y^-5 × x^-2
now also remember, a negative exponent means 1/...
so, this is
1/(y⁵) × 1/(x²) = 1/(y⁵x²)
now, let's have a look at the answer options and compare with our results above :
the first one is wrong.
the second one is correct.
the third one is correct.
the fourth, fifth and sixth ones are wrong.
Answer:
x=7/5 or 1.4
Step-by-step explanation:
5x+17=24
you would subtract 17 from both sides.
5x=7
Then you would divide 5 from both sides
x=7/5 or 1.4
1+1+1+1+1+1+1+1+3+9
= 20
Largest number used is 9
