Start by setting up two equations

Let x = number of beans with Martha
Let y = number of beans with Mary

Since total beans is 375, 
x + y = 375

Mary ate 24 beans, after this she must be having x - 24 beans
Similarly after eating 1/7y beans, mary must be having y - y/7 beans
Setting them equal to each other
x - 24 = y - y/7

Solving both equations gives x = 186, y = 189

10. During the hockey season, Elena
Debora [2.8K]

Answer:

Step-by-step explanation:

If I remember expanded form is putting all number in terms of being times 10 to a power.  starting with the ones place it's x10^0 which of course is just 1, so you don't need to include the x10 at all.

now, moving one either way  that 0 either  get 1 added to it or subtracted.  So in the 10s place it becomes x10^1 and the tenths place becomes x10^-1.  Similarly the hundreds place and hundreths place will have x10^2 and x10^-2 respectively.  So keep this pattern going to find each place of the number.  Can you list out what places are displayed in 5.625?

I will get you started, but let me know if you don't quite get it.  

5 + 6*10^-1 + ...

Can you figure out the rest?

Solve the measure of an angle is 161°. what is the measure of a supplementary angle?
lions [1.4K]
Supplementary angles sum up to 180°, suppose the supplement of 161° is x. Then
161+x=180
solving for x we subtract 161 from both sides
161-161+x=180-161
x=19
thus the supplement is 19°
