What is 6x+7y=4x+4y6x+7y=4x+4y

Mathematics
1 answer:
eimsori [14]3 years ago
6 0

we have

6x+7y=4x+4y

we figure out that

the solution is ----> (x,-4)

substitute the value of y=-4 in the equation

6x+7*(-4)=4x+4*(-4)

6x-28=4x-16

Combine like terms

6x-4x=28-16

2x=12

x=12/2

x=6

So the the missing value is x=6.

On the strip below, mark and label the location of each decimal. Please help! Thank you.
Alinara [238K]

0.09 is one tick mark Behind the 1/10 or 1 over 10 mark.

0.9 is the exact mark labled 9 over 10 or 9/10.

0.19 is exactly the mark behind the 2/10 mark or 2 over 10.

0.190 is on exactly the same mark as the one above-- on the mark behind the 2/10 mark.

0.019 is does not have a place on the strip. It is in the thousandths place not the hundredths or tenths places. That is why it doesn't have a place on the strip

Hope this helps you! :)

in year 4 the store sold 112% of the total number of scooters sold during the previous three years combined determine the number
Margarita [4]

Answer:

2, 240

Step-by-step explanation:

In the table, the values should be

Year 1   725  

Year 2   579

Year 3   696

Since Year 4 sold 112% of the previous 3 years combined, we add 725+579+696=2000. We can find 112% by writing a proportion.

\frac{112}{100} =\frac{x}{2000}

We solve through cross multiplication of numerator and denominator of the opposite fraction.

112(2000)=100(x)\\224000=100x\\2,240=x
