Answers

Answer:

(- [tex]\frac{15}{2}[/tex], 25 )

Step-by-step explanation:

Given the 2 equations

y = - 4x - 5 → (1)

y = - 2x + 10 → (2)

Substitute y = - 2x + 10 into (1)

- 2x + 10 = - 4x - 5 ( add 4x to both sides )

2x + 10 = - 5 ( subtract 10 from both sides )

2x = - 15 ( divide both sides by 2 )

x = - [tex]\frac{15}{2}[/tex]

Substitute this value into either of the 2 equations and evaluate for y

Substituting into (2)

y = - 2(- [tex]\frac{15}{2}[/tex] ) + 10 = 15 + 10 = 25

Solution is ( - [tex]\frac{15}{2}[/tex], 25 )

A dairy cow can produce up to 2,000 gallons of milk every 365 days. At this rate, a cow can produce x gallons of milk in 500 days. Which proportion should be used to find x

Answers

So if the cow can produce 2000 gallons of milk in 365 days, how many gallons can she produce in 1 day?
We find this by dividing 2000 by 365:

2000/365 = 5.4794 gallons of milk per day

Now, to find the amount of gallons she produces in 500 days, we simply multiply the number of gallons she produces in 1 day by 500:

5.4794 X 500 = 2,739.73 gallons in 500 days.

Answer: 5√10.

Step-by-step explanation:

250 is split into its prime factors as 2 * 5 * 5 * 5 which implies √250 = √(2 * 5 * 5 * 5). Now we can simplify this further by pulling out the number which is multiplied to itself. This gives √250 = 5 * √(2 * 5) = 5√10. Therefore the square root of 250 is √250 = 5√10.

Answers

Answer:

x=-1, y=-5

Step-by-step explanation:

y=3x-2 (1)

x-y=4 (2)

sub (1) into (2)

x-(3x-2)=4

x-3x+2=4

-2x=2

x=-1

sub x=-1 into (1)

y=3(-1)-2

=-3-2

y = -5

Therefore: x=-1, y=-5 :))

Answer:

x = -1, y = -5

Step-by-step explanation:

y = 3x - 2

x - y = 4

x - (3x - 2) = 4

x - 3x + 2 = 4

-2x + 2 = 4

-2x = 2

x = -1

x - y = 4

-1 - y = 4

-y = 5

y = -5

Check:

x - y = 4

-1 - (-5) = 4

-1 + 5 = 4

4 = 4

(1.2÷0.375−0.2)/(6 4/25 ÷15 2/5 +0.8) = (0.016÷0.12+0.7)/x

Answers

Answer:

x=1/3

read below to find out how I solved!

Step-by-step explanation:

break it down.

First do 1.2÷0.375−0.2 = 1.2.

it is now 1.2/(6 4/25 ÷15 2/5 +0.8) = (0.016÷0.12+0.7)/x

now do 6 4/25 ÷15 2/5 +0.8 = 3

it is now 1.2/3 = (0.016÷0.12+0.7)/x

now do 0.016÷0.12+0.7 and that is 5/6

now you have 1.2÷3 = 5/6 ÷ x

solve for x and you should get x = 1/3!!
