Answer:
answer= -x
Step-by-step explanation:
given: f(x)=3x+4
g(x)=4x+4
f(x)-g(x)= 3x+4-(4x+4)
=3x+4- 4x-4
=3x-4x+4-4
= -x+0
= -x
24 x 10^4, the 4 comes from with how many jumps it took to land on a whole number from 240,000.
X = cost of children's ticket
x +3 = cost of adults tickets
100x + 200(x+3) = 2100
100x + 200x + 600 = 2100
300x = 1500
x = 5
answer
children ticket costs $5
Firstly, we will let this mystery number we are finding be labelled as x. Double this number can be written as 2x. 5 less than double this number is written as 2x - 5. And because this number is between -7 and 13, we have the full inequality, -7 < 2x - 5 < 13.
To solve this inequality, we want to isolate x, so we add 5 to all 3 parts of the inequality. Doing so cancels out the - 5 in the middle, so our new inequality is -2 < 2x < 18. Now we want to divide all 3 parts of the inequality by 2 to isolate x, so now our final inequality is -1 < x < 9. Thus, we can say that x is between -1 and 9.
Answer:
x = 50
Step-by-step explanation:
The legs are perpendicular and so the triangle is a right triangle.
Using the Pythagorean Theorem, we get
48^2 + 14^2 = x^2 = 2304 + 196 = 2500. Then x is the positive square root of 2500, which is 50.
x = 50
