The difference of a number and 5 = n - 5
Twice that = 2(n - 5)
‘is’ is the equal sign, so the expression before is equal to 7.
Equation: 2(n - 5) = 7
Answer:
a + 1
to get 1 more than a you add 1 to a because you don't know what a is
Answer:
None of the above. It is non linear.
Step-by-step explanation:
here's two sets of numbers . Linear equations would have identical results.
500x + y = 63 y = 63 - 500x
1000x + y = 98 1500x + y = 135
1000x + 63 - 500x = 98 1500x + 63 - 500x = 135
500x = 35 1000x = 72
x = 0.07 x = 0.072
y = 28 y = 27
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

since they ran 12 in 1/3 of an hour multiply 12 by 3 to get a full hour. 12*3=36
