It’s the first one because if 5=3.75 and 10=7.5 and 12=9 they go up the same amount each time where as the second one goes 3=.4 and 4=1.2 and 10=6 the second one just doesn’t make sense so it would be the the one on the left :) hopefully that makes sense

If Bo deposited $400 in each child’s account, how much money was in Bo’s original paycheck?

( Help my cousin because I’m busy ) ❤️

Answers

for college, 1-1/2-1/5 = 3/10. Divided by 3 children, 3/10 /3 = 1/10

B. 400 = 1/10 of the total (from above), so 400 = x/10. x = 400*10 = 4000

4000 hope this helps

Mike jogged a total distance of 5 1/3 miles during the months of October and November. If Mike only jogger 1/6 mile every day, Which expression shows the number of days in which he went jogging?

Answers

Answer:

D

Step-by-step explanation:

If he jogged [tex]x[/tex] miles every day, and he jogged a total distance of [tex]y[/tex] miles, then he runs for [tex]y/x[/tex] days. This is an extension of the [tex]d=rt[/tex] or distance equals rate times time.

We plug in for y and x to get that he runs for [tex]5~1/3~~/~~1/6[/tex].

So, the answer is [tex]\boxed{D}[/tex] and we're done!

Let f(x)=-x-5 and g(x)=2x+3. Find the indicated value:
x when g(x)=1

Answers

Answer:

-9

Step-by-step explanation:

few words about function notation.  If f is a function, then f(x) is the

value of the function at x, usually denoted by some sort of rule for finding

the value of the function given that you know the value of x.  f(a) would be  

the value of the function at a, and f(4) would be the value of the function at,

=4

In this case the value of the function f at x, or f(x) is given by the rule:

f(x) = -x - 5   You want to know f(4), which is the value of the function at

4, so f(4) = -(4) - 5 = -9
