Let x be the unknown number. The equation is going to be 7/28=25/x, now we cross multiply. 7*x=25*28, 7x=700, divide both sides by 7 and you should get 100, So, x=100 and 7/28=25/100

Answer: D
Step-by-step explanation: Im vv sure, is this a test?
Answer: (-1,4)
Step-by-step explanation:
y=-2x+2 y=7x+11 <----- substitute this equation for y in the
equation y=-2x+2
7x+11=-2x+2 Add 2x to both sides
9x+11=2 Subtract 11 from both sides
9x=-9 Divide both sides by 9
x=-1
y=-2(-1)+2 Plug in x to one of the equations, I chose y=-2x+2
y=2+2 because it was the easiest, then solve
y=4
Solution is (-1,4)
Hi :)
The find out the circumference of M,we'll need to calculate diameter (AC)
We can calculate AC with Phytagora's formula :
AC²=OC²+OA²
AC²=6²+8²
AC²=100 ⇒ AC = 10
Circumference : D*π = 10*π = 10*3,14159 ≈ 31,4159 m
