The first one is correct.
DC=AC
13 scaled down by 1/5
= 13 ÷ 1/5
= 13 × 5/1
= 65.
The answer is the the second or B
The answer is Step 2.
The exponential equation is: 3ˣ⁺¹ = 15.
Step 1: log3ˣ⁺¹ = log15
Step 2: (x + 1) * log3 = log15
Step 3: x + 1 = log 15 / log 3
Step 4: x + 1 = 1.18 / 0.48
Step 5: x + 1 = 2.46
Step 6: x = 2.46 - 1
Step 7: x = 1.46
Answer:
X + Y could equal to
or
.
Step-by-step explanation:
2X = 5Y
Y = 
X = 
Hence, X + Y could equal to X +
=
or Y +
=
.
Hence, X + Y could equal to
or
.
