Answer:
Our expression is 205+2d where d is days past 60.
Step-by-step explanation:
Since the sunflower is 205 centimeters at 60 days, every day after 60 will be greater than 205. We will start with 205 in our expression.
205
Now, each day after 60 the sunflower grows 2 centimeters per day. So day 61 will be:
205+2
Day 62 will be:
205 +2+2
Notice, that for two days past 60, the sunflower has grown 2 times as much.
Our expression is 205+2d where d is days past 60.
Answer:
94%
Step-by-step explanation:
= 60/1000 ×100

= 100% - 6%
= 94%
94% people know how to ride the bike
ANSWER

EXPLANATION
The first equation is

The second equation is

We want to eliminate y, so we multiply the first equation by



We now subtract equation (3) from (2)



Multiply both sides by



Substitute into the first equation to solve for x .

Multiply to obtain



Multiply both sides by 2.
