Answer:
33.33
Step-by-step explanation:
We have, 90% × x = 30
or, 90
/ 100 × x = 30
Multiplying both sides by 100 and dividing both sides by 90,
we have x = 30 × 100
/ 90
x = 33.33
If you are using a calculator, simply enter 30×100÷90, which will give you the answer.

Answer:
A. t=4n+950
B. h=9.5n
C. d=9.5n-(4n+950)
D. The tortoise will finish first.
Step-by-step explanation:
To find the first two equations, we put the rate at which they are traveling in front of the n, and then add where they start. Since the tortoise gets a 950 meter head start, we add 950. The hare is starting at the start line so we don't need to add anything.
For answer c, we need to subtract the two equations from each other to figure out when they would pass each other. d=(equation h)-(equation t).
For the final answer, all you need to do is plug the first two equations into a graph, and then find where each line is at the point of y 1,600. (To make the graphs I replaced the n with x and the t and h with y.) Using this, we are able to see who got there first, which was the tortoise.
The answer is 5 If you dont like this you first see what you can multiple to get to 15 first.
Answer:
The equation of the line is y = (5/2)x + 5.
Step-by-step explanation:
When both line are parallel, they share the same gradient value so the equation will be y = (5/2)x + b. Next, you have to find the value of b, by substituting the coordinates into the equation :
y = (5/2)x + b
let x = -2, y = 0,
0 = (5/2)(-2) + b
0 = -5 + b
b = 5
