Answer: x= 3.8

Step-by-step explanation:

21.1 - 8.3 = 3.8

x= 3.8

Answer:

X = 3.8

Explanation: 12.1 minus 8.3 equals the missing value

11n - 11 + 35 = 3n

8n = - 24

n = - 3

Answer:

Step-by-step explanation:

Simplifying

11(n + -1) + 35 = 3n

Reorder the terms:

11(-1 + n) + 35 = 3n

(-1 * 11 + n * 11) + 35 = 3n

(-11 + 11n) + 35 = 3n

Reorder the terms:

-11 + 35 + 11n = 3n

Combine like terms: -11 + 35 = 24

24 + 11n = 3n

Solving

24 + 11n = 3n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-3n' to each side of the equation.

24 + 11n + -3n = 3n + -3n

Combine like terms: 11n + -3n = 8n

24 + 8n = 3n + -3n

Combine like terms: 3n + -3n = 0

24 + 8n = 0

Add '-24' to each side of the equation.

24 + -24 + 8n = 0 + -24

Combine like terms: 24 + -24 = 0

0 + 8n = 0 + -24

8n = 0 + -24

Combine like terms: 0 + -24 = -24

8n = -24

Divide each side by '8'.

n = -3

Simplifying

n = -3

Answer:

9. 1.24 mL

10. $5.93

Step-by-step explanation:

Question 9:

If the dosage of medicine is 0.01 mL per pound of weight of the patient, and the patient's weight is 124 pounds, we can set up an equation to solve for how much medicine the patient would need to take:

Dosage of medicine per pound of body weight x Total body weight = Total medicine required

                                                               OR

0.01 * w = m,

where w is total body weight and m is total medicine required.

To solve for the dosage the patient needs, just plug the numbers into the right places (124 for w and leave m as it is):

0.01 * 124 = m

1.24 = m

Therefore, a patient with a body weight of 124 pounds would need a 1.24 mL dosage.

Question 10:

To make the multiplication easier, we could rewrite 15% as 0.15 ( because 15% = 15/100):

0.15 * Total bill = Total tax payed for bill (Also can be written as [tex]\frac{15}{100} * 39.51[/tex])

                                 OR

0.15*39.51 = Total tax

5.9265 = Total tax

5.93 = Total tax <-------- (rounded)

Answer:

The best angle measurement that best fits Aliaa's circle partition is three angles of 120° each.

Step-by-step explanation:

The sum of angles at the center of the circle = The sum of angles at a point = 360°

Therefore, to partition the circle into three congruent angles, the measurement of each of the partition should be 360°/3 = 120°

The steps to partition a circle into three are;

1) Draw the diameter of the circle, to intersect the circumference of the circle at points A and B

2) Mark a point, C, at a distance of half the radius from the center of the circle,  O, to the point, B, on the circumference, using a straight edge

3) Draw a perpendicular line to the diameter of the circle, through the point, C, to intersect the circle circumference at points D and E)

4) Draw radial lines from the circle center, O, to the points D and E

5) The segments OA, OB, and OE, are segment lines partitioning the segment into three congruent angles.

Answer:

Step-by-step explanation:

Probability of rolling a 5 =1/6

So no. of times 5 is expected when the number cube is rolled out 570 times = 570*1/6 = 95 times

1)First determine the probability of rolling a 5

2)Since you can only roll a 5 once in a 6-sided cube the probability is ⅙ or about 0.1667

3)Multiply the probability and the total number of rolls

.1667 * 570= 95

Answer : 95 times

Step-by-step explanation:

Answer:

The y- intercept could only be: B) (0, -3).

Step-by-step explanation:

The Y intercept is found when X=0, so the first value in the ordered pair must be 0. Because the line crosses the y axis BELOW the x axis, the value must be negative. Therefore, out of all the provided options, the answer could only be (0,-3).

Step-by-step explanation:

The first step to do is to line up the decimal points. We have to add a zero to 0.8 so that the decimal points will align (this does not change the value).

+0.80

Then bring down the decimal point into the answer column, and add like normal.

Answer:

[tex]\frac{3}{7}[/tex] × [tex]\frac{5}{4}[/tex]

Step-by-step explanation:

Step 1. Turn the second fraction upside down (it becomes a reciprocal):

[tex]\frac{4}{5}[/tex] becomes [tex]\frac{5}{4}[/tex]

Step 2. Multiply the first fraction by that reciprocal:

[tex]\frac{3}{7}[/tex] × [tex]\frac{5}{4}[/tex] = ?

3 x 5 = 15

7 x 4 = 28

[tex]\frac{3}{7}[/tex] × [tex]\frac{5}{4}[/tex] = [tex]\frac{15}{28}[/tex]

Step 3. Simplify the fraction:

[tex]\frac{15}{28}[/tex] = [tex]\frac{15}{28}[/tex]  You can't simplify this fraction

Answer: Commutative Property of Multiplication/Addition

Step-by-step explanation:

The commutative property is simple

x + y = y + x

or for multiplication

x * y = y * x

After solving the equation, the value obtained for x will be equal to -17/5.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given statement in the question,

The equation for the given statement will be,

(4x + 1)/3 = (x - 5)/2

8x + 2 = 3x - 15

8x - 3x = -15 - 2

Solve the equation for x.

5x = -17

x = -17/5

Hey there! I'm happy to help!

Let's call the cost of a bread loaf b and the cost of a milk gallon m. Here is the info we have.

4b+3m=20

6b+2m=25

We solve one equation for b or m (we will solve the first one for b.

4b+3m=20

Subtract 3m from both sides.

4b=20-3m

We divide both sides by 4.

b=5-3/4m

We plug this value of b into the second equation to solve for m.

6(5-3/4m)+2m=25

We use distributive property to undo the parentheses.

30-4.5m+2m=25

We combine like terms.

30-2.5m=25

We subtract 30 from both sides.

-2.5m=-5

We divide both sides by -2.5

m=2

We plug this m into one of the original equations to find b.

4b+3(2)=20

4b+6=20

Subtract 6 from both sides.

4b=14

Divide both sides by 4.

b=3.5

So, a loaf of bread costs $3.50 and a gallon of milk costs $2.00.
