Answer:
I think the answer is (-3,1)
Write the decimal number as a fraction
(over 1)
3.1818 = 3.1818 / 1
Multiplying by 1 to eliminate 4 decimal places
we multiply top and bottom by 4 10's
Numerator (N)
N = 3.1818 × 10 × 10 × 10 × 10 = 31818
Denominator (D)
D = 1 × 10 × 10 × 10 × 10 = 10000
N / D = 31818 / 10000
Simplifying your fraction
= 31818/10000
= 15909/5000
= 3 909/5000. Hope this helped!!!
Answer:
Step-by-step explanation:
To figure this out divide 11 into the top numbers then multiply the result with the bottom number:
44/11 = 4 so multiply 15 X 4 and get 60
For the last one divide 90 by 15 and get 6. Multiply 6 with 11 to get 66.
The answer is <span>x - 1 = 3x + 9
All steps are:
</span>Step 1: 4ˣ⁻¹ = 64ˣ⁺³<span>
Step 2: 4</span>ˣ⁻¹ = (4³)ˣ⁺³ <span>
Step 3: 4</span>ˣ⁻¹ = 4³ˣ⁺⁹
Step 4: x - 1 = 3x + 9
Step 5: x - 3x = 1 + 9
Step 6: -2x = 10
Step 7: x = 10/-2
Step 8: x = -5
