2x + y = -4<br> 2x + 3y = 4
kirill115 [55]

Answer: x=4 ; y=<u> -4</u>

                            3

Step-by-step explanation:

2x + y = -4 .(-3)

2x + 3y = 4

-6x-3y=12

<u>2x + 3y = 4</u>

4x=16

x= <u>16</u>

    4

x=4

2x + 3y = 4

2.4+3y=4

8+3y=4

3y= -8+4

y=<u> -4</u>

There was a 340,000 cattle placed on feed. Write an equivalent ration that could be used to find how many of these cattle were b
ioda

An equivalent ratio would be 4/10, and the number of cattle would be 136,000.Explanation:The question asks for an equivalent ratio. This means a fraction that is equivalent to the fraction between 700-799, which is 2/5.To create an equivalent fraction, we multiply the numerator and denominator by the same number. Multiplying both by 2, we get (2*2)/(5*2) = 4/10.Tenths are useful when dealing with thousands, because taking a tenth involves getting rid of a zero. This means that 1/10 would be 34000; 4/10 would be 4 times that: 4(34000) = 136000.
