Answer:
y = 105 ÷ 6 = 35/2
Step-by-step explanation:
∵ 15/3 = 2y/7
∴ 2y × 3 = 15 × 7
∴ 6y = 105
∴ y = 105 ÷ 6 = 35/2
Answer: 20 miles
Step-by-step explanation:
Hi, since the situation forms a right triangle (see attachment) we have to apply the Pythagorean Theorem:
x^2 = a^2 + b^2
Where x is the hypotenuse of the triangle (in this case the distance between Dayton and Belleville) and a and b are the other sides.
Replacing with the values given:
x^2 = 16^2 + 12^2
x^2 = 256+144
x^2 = 400
x = √400
x = 20 miles

Answer:
( - 2 - 5m ) / 3
Step-by-step explanation:
15m + 9n = - 6
9n = - 6 - 15m
Divide by 3 on both sides,
9n / 3 = - 6 / 3 - 15m / 3
3n = - 2 - 5m
n = ( - 2 - 5m ) / 3

Answer:
- 9
Step-by-step explanation:
let x be the input value, then the function is
y = 4x + 10 ← equate to - 26
4x + 10 = - 26 ( subtract 10 from both sides )
4x = - 36 ( divide both sides by 4 )
x = - 9
Thus the input is x = - 9
