Answer:
Step-by-step explanation:
6/9+x=7/10
x=7/10-6/9
when adding fractions both denominators must be equal, we’ll make them 90
x=(7/10)(9/9)-(6/9)(10/10)
x=63/90-60/90
x=3/90, the greatest divisor of 3 and 90 is 3 so divide both the numerator and denominator by 3
x=(3/3)/(90/3)
x=1/30
Answer:
5x^6 -60x^2
Step-by-step explanation:
(5x)(x^5 - 12x)
Distribute the 5x to each term in the second parentheses
5x* x^5 -5x*12
5x^6 -60x^2
5. subtraction PoE
6. reflexive property
7. substitution
8. def. of congruent
I hope that is right and it helped.
Equation would be: 25.15 - 1.75x
Where, x = number of days.
Substitute for x = 3,
= 25.15 - 1.75(3)
= 25.15 - 5.25
= 19.90
In short, Your Answer would be $19.90
Hope this helps!
