Answer: -0.15
Explanation:
0.15=x0.3
We move all terms to the left:
0.15-(x0.3)=0
We add all the numbers together, and all the variables
-(+x0.3)+0.15=0
We get rid of parentheses
-x0.3+0.15=0
We move all terms containing x to the left, all other terms to the right
-x0.3=-0.15
x=-0.15/1
x=-0.15
Question:
Jordyn, Teri, and Morgan are going to have a kite-flying contest. Jordyn and Teri each have one roll of kite string. They also each have 45 yards of extra string. Morgan has three rolls of kite string plus 10 yards of extra string. All the rolls of string are the same length. The girls want to see who can fly their kite the highest.
Since Jordyn and Teri have fewer rolls of kite string, they decide to tie their string together, so their kite can fly higher. Write at least two expressions to show how much kite string Jordyn and Teri have. Let x represent the number of yards of string on one roll.
Answer:
Step-by-step explanation:
From the complete question, we have:
<u>Jordyn & Teri</u>
<u></u><u></u>
<u></u><u></u>
<u></u>
<u>Morgan</u>
<u></u><u></u>
Required
Expression for Jordyn and Morgan
Let the total kite by Jordyn and Teri be represented with y
This is calculated as:
This gives:
1 roll is represented with x.
So:
This can be rewritten as:
Answer:
see below
Step-by-step explanation:
Choose a couple of values for x. Figure out the corresponding values for y. Plot those points and draw a line through them.
Let's choose x=0 and x=4. Then the corresponding y-values are ...
y = 2·0 = 0 . . . . . point (x, y) = (0, 0)
y = 2·4 = 8 . . . . . point (x, y) = (4, 8)
These are graphed below.
