Find the value of y for a given value of x, if y varies directly with x

Mathematics

Sophie [7]3 years ago

It is said that y varies directly to x which can be written as follows:

y = kx

where k is the constant of proportionality. 

To be able to solve the problem, we need to determine the value of k. We do as follows:

y = kx
-252 = k(84)
k = -3

y = -3x
y = -3(74)
y = -222

Hope this helps. Have a nice day.

A pencil and ruler cost 1.50 together. The ruler is 1.00 more. How much is pencil
Stella [2.4K]
Ok so the solution which greenrune will (hopefully) correct


total is 1.5
p+r=1.5
rule is 1 more than pencil
r=1+p
sub 1+p for r
p+1+p=1.5
2p+1=1.5
minus 1 from both sides
2p=0.5
divide both sides by 2
p=0.25

pencil=$0.25

12(5 x-4.5)=36 what is the value of x
-Dominant- [34]

Answer:

x=

3 /2

Step-by-step explanation:

12(5x−4.5)=36

(12)(5x)+(12)(−4.5)=36(Distribute)

60x+−54=36

60x−54=36

Step 2: Add 54 to both sides.

60x−54+54=36+54

60x=90

Step 3: Divide both sides by 60.

60x

60

=

90 /60

x=

3 /2
