This number is standard form ninety billion.
To find the value of y in the given equation, substitute the given value of x to the equation.
y = 4x + 2x² -x³
Substitute 2 for all x's.
y = 4(2) + 2(2²) - 2³ = 8
Therefore, the value of y is 8.
Answer:
it reduces to 7:8
Step-by-step explanation:
just put it like a fraction like 140/160. it simplifies to 7/8
Eighths and their multiples are common fractions which I recommend memorizing, but to actually solve this, you use the literal meaning of a fraction and divide 5 by 8. See the long-division below (it was surprisingly difficult to type, so I hope it helps!).
To round 0.625 to the nearest hundredth, we go to the second decimal place, which is 5, so we round up to 0.63.
