Carlos has been working out to get stronger. At the beginning, Carlos was able to do 20 pushups. Each week he is able to do 5 more pushups. Which equation shows the total number of pushups, t, that Carlos can do after a certain number of weeks w?

20+5w=t

Step-by-step explanation:

He starts with 20, so no matter what 20 will be added to the equation. Carlos gains 5 pushups each week. So that can be written as: 5w, because 5 pushups per week. So, it looks like this, 20+5w=t. The =t at the end represents the total amount of pushups he can do after w weeks.

Hope this helps.

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
