4x – 3y=8 2. 5x – 2y = -11

AlladinOne [14]

Answer:

$x = -7$

$y = - 12$

Step-by-step explanation:

The given system is:

4x-3y=8

5x-2y=-11

We make x the subject in the top equation to get:

$x = \frac{3}{4}y + 2$

Plug this expression for x in the bottom equation to get

$5( \frac{3}{4}y + 2) - 2y= - 11$

We expand to obtain

$\frac{15}{4} y + 10 - 2y = - 11$

Multiply through by 4

$15y + 40 - 8y = - 44$

Group similar terms

$15y - 8y = - 44 - 40$

$7y = - 84$

$y = - \frac{84}{7} =-12$

This means

$x = -12\times \frac{3}{4} + 2$

$x = - 7$

The temperature was 19 degrees Fahrenheit on Monday and 31 degrees Fahrenheit on Tuesday. How much did the temperature rise?

Lera25 [3.4K]

Answer:

31-19=12°F

12°F

Step-by-step explanation

If it was 19 degrees on Monday and 31 degrees on Tuesday you have to see how much did it go up in temp. So..

the difference between 19 and 31 is 12, so that means it went up by 12°F.

Two ratios that are equivalent to 5/7

grigory [225]

You could pick just about anything 3/8 is not the same thing as 5/7 and neither is 3/4

Something that is equivalent would be something like 10/14 or 20/28
