Answer:
y = -2x + 17
Step-by-step explanation:
y has to equal 5:
incorrect
y = -2x - 17
y = -2(6) - 17
y = -12 - 17
y = -29
incorrect
y = -2x - 16
y = -2(6) - 16
y = -12 - 16
y = -28
incorrect
y = -2x + 16
y = -2(6) + 16
y = -12 + 16
y = 4
correct
y = -2x + 17
y = -2(6) + 17
y = -12 + 17
y = 5
Step 1
<u>Find the total meters of ribbon</u>
we know that
One spool of ribbon holds meters
so
by proportion
find the amount of meters of spools
the total meters of ribbon is
Step 2
<u>Find the total cost of the ribbon </u>
Multiply by the total meters of ribbon
therefore
the answer is
The total cost of the ribbon is
Step 3
<u>Find how much ribbon will be left</u>
we know that
the club uses meters to complete a project
so
Subtract meters from the total meters of ribbon
the total meters of ribbon is -----> see Step 1
therefore
<u>the answer is</u>
The ribbon that will be left is
A cube represents 1,000 and a flat 100. You can solve this problem by saying the number out loud. "One thousand, two hundred." That means that you need one thousand (cube) and two hundreds (flat). So one cube and two flats will be 1,000+100+100, which equals 1,200.
