Step-by-step explanation:

6.05-12.50=13.55

48 divided by 13.55=3.542

x=3.542

Answer:

X= 1

Step-by-step explanation:

6.05x-12.5=48 Add 12.5 to both side

         +12.5 +12.5

6.05x = 60.5 now divide both sides by 6.05

/ 6.05    /60.5

X     =  1

Answer: Following the rules of PEMDAS, you want to divide both sides of the equation by -2. This would change your equation to x+3=5. Then you move your constant to the right-hand side and change its sign. Your equation is now x=5-3. subtract 5-3 and your answer is x=2.

P(A∩B) = 0.12

Step-by-step explanation:

Given:

Students receive financial aid P(A) = 40% = 0.4

Students receive financial aid and first generation P(B/A) = 30% = 0.3

Find:

Probability [Selected student receives financial aid and is first generation college student] P(A∩B)

Computation:

P(A∩B) = P(A) x P(B/A)

P(A∩B) = 0.4 x 0.3

P(A∩B) = 0.12

Step-by-step explanation:

Original equation:

2500 + 110h < 3000

Subtract 2500 from both sides

110h < 500

Divide both sides by 110

h < 4.5 (rounded to the nearest tenth)

Answer:

  x = 6

Step-by-step explanation:

The parallel lines divide the sides proportionally. So, we can write the equation ...

  x/4 = (x +3)/6

  3x = 2(x +3) . . . . . multiply by 12

  x = 6 . . . . . . . . . . . subtract 2x

Answer:12B - 12M = 36

12B + 15M = 63

Subtract one from the other:

12B + 15M = 63

-(12B - 12M = 36

-------------------------

0 + 27M = 27

27M = 27

M = 1

B - M = 3 (from the original equations)

B - 1 = 3

B = 4

Answer:  -6 and 6

Step-by-step explanation:  

Possible factors that could produce 3x² + 6x +3 are  (x + 1)(3x + 3)

the solution for values of x: x+1=0, x= -1  3x+3=0,  3x= -3 . x= -1 . Same.

Possible factors that could produce 3x² - 6x +3 are  (x - 1)(3x - 3)

the solution for values of x: x-1=0, x= 1  3x-3=0,  3x= 3 . x= 1 . Same.

From the attached graph of the possible equations, you can see that 9 and -9 won't produce ONE real solution. They each have "zeros" at two points on the x-axis. That is two solutions that would make x = 0.

The equations with -6 and +6 each touch the x-axis at only one point each.

Answer:

Step 1 Divide all terms by a (the coefficient of x2).

Step 2 Move the number term (c/a) to the right side of the equation.

Step 3 Complete the square on the left side of the equation and balance this by adding the same value to the right side of the equation.

B: u = (1,5) and v = (-5,1)

Step-by-step explanation:

edge 2021

The pair of vectors which are orthogonal to each other will be u = ⟨1, 5⟩ and v = ⟨–5, 1⟩. Then the correct option is B.

The quantity which has magnitude, direction and follows the law of vector addition is called a vector.

For the orthogonal vector, the dot product of two vectors will be zero.

Check first option, we have

u·v = ⟨–3, 2⟩·⟨–2, 1⟩

u·v = 6 + 2 = 8 (incorrect)

Check second option, we have

u·v = ⟨1, 5⟩·⟨–5, 1⟩

u·v = –5 + 5 = 0 (correct)

Check third option, we have

u·v = ⟨2, 1⟩·⟨–4, 3⟩

u·v = –8 + 3 = –5 (incorrect)

Check fourth option, we have

u·v = ⟨2, 3⟩·⟨3, 1⟩

u·v = 6 + 3 = 9 (incorrect)

Then the correct option is B.

Step-by-step explanation:

−2 1/6 divided by 1 1/4:

1) to divide that mixed number we'll need to turn it into an improper fraction:

[tex] - 2\frac{1}{6} = - ( \frac{6 \times 2 + 1}{6} ) = - \frac{13}{6} \\ 1 \frac{1}{4} = \frac{4 \times 1 + 1}{4} = \frac{5}{4} [/tex]

2) now let's divide it, reciprocating 1 1/4 and multiplying both fractions one by another:

[tex] - \frac{13}{6} \times \frac{4}{5} = - \frac{52}{30} = - \frac{26}{15} [/tex]

Answer:

570 grams of water

Step-by-step explanation:

171 divided by 6 = 28.5

28.5 grams are in 1 ounce

so Multiply 28.5 by 20 to get the new amout which is 570

The amount of water present in 20 ounces of grapefruit juice will be 570 grams.

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

A 6-ounce serving of grapefruit juice contains 171 grams of water.

The ratio of the amount of grapefruit and water present will remain constant.

Let 'x' be the amount of water present. Then the equation is given as,

x / 20 = 171 / 6

x = 20 · 171 / 6

x = 570 grams

The amount of water present in 20 ounces of grapefruit juice will be 570 grams.
