Step-by-step explanation:
tan30° = Height of person / (Distance away from river bank + river's width) = 1/√3.
Therefore 1.6m / (2m + x) = 1/√3
By cross multiplication, 1.6√3 = 2 + x.
Hence, x ≈ 0.77m.
Answer: the equivalent equation is found by distributing the 1/4 to get 4+3x=28
the first step is subtract 4 to both sides
the second step is divide both sides by 3
the answer is x=8
Step-by-step explanation:
Answer:
Step-by-step explanation:
1/4 of 2/3 is just (1/4) / (2/3) or (1/4)(3/2)
1/4 * 3/2= 3/8
She needs to use 3/8 of a cup
The number 1.41421356.... is a(n) rational number because its a repeating decimal that can be written as a fraction.
This is a trial and error answer.
Suppose that QT = -3, then
x + 2 = y
2x = y + 3
Apply substitution,
2x = (x+2) + 3
2x = x + 5
x = 5
y = 7
chek your answer,
x + 2 = y
<span>5 + 2 = 7</span>
