Erica is making feathered caps for her school play. Each cap must have 3 feathers. Write an equation that represents the number

FrozenT [24]

Answer:

$f=3c$

Step-by-step explanation:

Given:

Number of feathers = $f$

Number of caps = $c$

Number of feathers in each cap = 3

Now, solving by setting up a proportion.

1 cap has 3 feathers. 'c' caps has 'f' feathers.

This gives,

$\dfrac{1}{3}=\dfrac{c}{f}$

Solving by cross multiplication, we get:

$1\times f=3\times c\\\\f=3c$

Therefore, the equation representing the number of feathers 'f' Erica needs to make 'c' caps is given as:

$f=3c$

How would you solve -7x-4y=16

Anni [7]

So one easy way is to make the equation equal to only one place holder so
-7x-4y=16
add 7x to both sdies
-4y=16+7x
multiply both sides by -1
4y=-16-7x
divide both sides by 4
y=-4-7/4x
subsitute values for x and get values for y
exg
if x=0 then y=-4
if x=1 then y=-5 3/7

fredd [130]

Answer:6111 km/hr

Step-by-step explanation:

Given

Distance travels by plane d=22,000 km

time taken t=3.6 hours

$\text{distance}=\text{speed}\times\text{time}$
