Answer:

let one part =x

part of vinegar= x

part of oil =2x

part of oil +part of vinegar = 450ml

2x+x=450

3x=450

x=450/3

x=150

part of vinegar=150ml

part of oil= 300ml

The amount of oil used by Ollie is 300ml.

The linear equations in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.

Suppose the vinegar is x ml.

So, the oil is 2x ml.

Ollie makes 450mls of salad dressing.

⇒ 2x + x = 450

Solve the above linear equation for x.

⇒ 3x = 450

⇒ x = 150ml

Therefore, amount of oil she used = 2 × 150ml = 300ml.

Hence, the amount of oil used by Ollie is 300ml.

Answer:

D. 8 cm

Step-by-step explanation:

Reference angle = 60°

Opposite side = BC = 8√3

Adjacent side = AC = ?

Thus:

Tan (60) = opp/adj

Tan (60) = (8√3)/AC

AC*Tan(60) = 8√3

Divide both sides by tan (60)

AC = (8√3)/Tan(60)

AC = (8√3)/√3 (tan 60 = √3)

AC = 8 cm

Answer:

x < 3

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

x= -2.........&.........y= -1

Step-by-step explanation:

(x,y)=(-2,-1)

Answer:

There are 153 combinations

Combinations - any two from eighteen is given by the formula 18C2 or 18! / (2!*16!)

= 18 * 17 / 2 = 153

OK that is the maths - now the explanation

The first sock can be any of 18

The second sock can be any of 17 (one already been selected and they must be mismatched)

Therefore there are 18*17 = 306 permutations she could make

However the question asks for "combinations" not "permutations"

A green sock on the right foot and a yellow sock on the left foot is deemed to be a different "permutation" to a yellow sock on the right foot and a green sock on the left foot. HOWEVER, they are regarded as the same "combination" in both cases you have one green and one yellow sock.

Therefore for combinations we must divide the 306 permutations calculated above by 2 = 153

FYI Walton has incorrectly given you the value of 18!. That would only apply if Martha Mathy had 18 feet!

Answer:

x = -3

y = -6/5

Step-by-step explanation:

To find the x-intercept(s), substitute in 0 for y and solve for x.

2x + 5(0) = -6

x = -3

Find the y-intercepts.

To find the y-intercept(s), substitute in 0 for x and solve for y.

2(0) + 5y = -6

y = -6/5

Answer:

B heppppppp tarada ejejjejejeje

If I understand this right:

3/4=24

24/3=8

8*4=32

You divide the number by the numerator, and then multiply that number by the denominator.

If you mean you want 3/4 of 24 then you divide 24 by 4, which equals 6. And then multiply 6 and 3, which equals 18
