it's D because 5 time the difference of means it's gotta be 5 time the answer of a problem in parenthesis , the rest is quite logical so... yeah it's D

What you gotta take from this problem:

What Joe got during break = 2t+2

What his sister gave him = 3t

What he has total = 10 tadpoles.


Now to assemble this equation:

2t+2+3t=10

Now combine like terms to get 5t+2=10

Subtract 2 on each side of the equation to get 5t=8

Now you would divide 5 on each side and get t=1.6 , however since you can't have a .6 of a tadpole, you would have to round it up to 2.

statuscvo [17]

Answer:

<em>k=-3</em>

Step-by-step explanation:

<u>Equation of a line</u>

The general equation of a line can be written as:

Ax+By=C

The x-intercept is the point where the line crosses the x-axis, i.e. y=0, thus replacing x=3 and y=0:

A(3)+B(0)=C

3A=C

Solving for A:

A=C/3

The y-intercept is the point where the line crosses the y-axis, i.e. x=0, thus replacing x=0 and y=5:

A(0)+B(5)=C

5B=C

Solving for B:

B=C/5

Replacing into the general equation:

\displaystyle \frac{C}{3}x+\frac{C}{5}y=C

Simplifying by C:

\displaystyle \frac{x}{3}+\frac{y}{5}=1

The point P(k,10) belongs to the line, thus:

\displaystyle \frac{k}{3}+\frac{10}{5}=1

Operating:

\displaystyle \frac{k}{3}+2=1

\displaystyle \frac{k}{3}=-1

Multiplying by 3:

\boxed{k=-3}
