Given m<12= 121 and m<6= 75, find the measure of each missing angle.

Answers

Answer/Step-by-step explanation:

Given:

m<12 = 121°

m<6 = 75°

a. m<1 = m<6 (vertical angles)

m<1 = 75° (substitution)

b. m<12 = m<1 + m2 (alternate exterior angles)

121° = 75° + m<2 (substitution)

121° - 75° = m<2 (subtraction property of equality)

46° = m<2

m<2 = 46°

c. m<1 + m<2 + m<3 = 180° (angles on a straight line)

75° + 46° + m<3 = 180° (substitution)

121° + m<3 = 180°

m<3 = 180° - 121° (subtraction property of equality)

m<3 = 59°

d. m<4 = m<3 (vertical angles)

m<4 = 59° (substitution)

e. m<5 + m<4 + m<6 = 180° (angles on a straight line)

m<5 + 59° + 75° = 180° (substitution)

m<5 + 134° = 180°

m<5 = 180° - 134° (Subtraction property of equality)

m<5 = 46°

f. m<7 = m<12 (vertical angles)

m<7 = 121° (substitution)

g. m<8 = m<4 (vertical angles)

m<8 = 59° (substitution)

h. m<9 = m<6 (Alternate Interior Angles)

m<9 = 75° (substitution)

i. m<10 + m<9 = 180° (Linear Pair)

m<10 + 75° = 180° (substitution)

m<10 = 180° - 75° (Subtraction property of equality)

m<10 = 105°

j. m<11 = m<8 (vertical angles)

m<11 = 59° (substitution)

k. m<13 = m<10 (vertical angles)

m<13 = 105° (substitution)

l. m<14 = m<9 (vertical angles)

m<14 = 75° (substitution)

The distance between two towns is 130 kilometers. There are approximately 8 kilometers in 5 miles.

Which measurement is closest to the number of miles between the two towns?

Please Give A Good Answer Ill Give Brainest And Extra Points ​

Answers

Answer: 81 miles

Step-by-step explanation:

From the question, we are informed that the distance between two towns is 130 kilometers and that there are approximately 8 kilometers in 5 miles.

The measurement that is closest to the number of miles between the two towns goes thus:

Firstly, we need to divide 130 kilometers by 8 kilometers. This will be:

= 130/8

= 16.25

Then, we multiply 16.25 by 5 to get the number of miles between the two towns. This will be:

= 16.25 × 5 miles

= 81.25 miles

= 81 miles

For the following equation, find a solution for the variable. Show all of your work and use complete sentences to explain the solving process that you used to find a solution for the equation. Be sure to include at least two terms from the word bank.

6 = 3 x - 9

Answers

Answer:

x=5

Step-by-step explanation:

solution;

6=3x-9(carry alike terms to the same side that'd be +6-9)

+9+6=3x

15=3x(divide both sides by 3)

5=x

(thanks,sorry and welcome)

The solution to the given equation 6 = 3x - 9 would be variable x = 5.

What is the equation?

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

To determine a solution for the variable in equation 6 = 3x - 9, we can begin by isolating the variable on one side of the equation. To do this, we can add 9 to both sides, giving us:

6 + 9 = 3x

This simplifies to:

15 = 3x

The next step is to divide both sides of the equation by 3, which will give us the value of x.

15/3 = 3x/3

Simplifying we get

5 = x

Thus, the solution for the variable is x = 5.

The number of loaves of bread that can be baked is proportional to the amount of flour used. Determine the number of loaves that can be baked with 15 cups of flour

Answers

Answer:

3 loaves

Step-by-step explanation:

See attachment for complete question.

Represent Loaves with L and Flour with F

Since L is proportional to F, the relationship can be defined as:

L = kF

Where k represent the constant of proportionality

When L = 4, F = 20

Substitute these values in the above formula.

4 = k * 20

Divide both sides by 20

4/20 = k

⅕ = k

k = ⅕

To solve for 15 cups of Flour, we have:

F = 15

Substitute 15 for F and ⅕ for k in L = kF

L = ⅕ * 15

L = 3

Hence, 3 loaves will be baked using 15 cups of flour

this is an inequality, could you explain as well? will give out brainliest answer :)

Answers

Answer:

x≥-8

Step-by-step explanation:

Let's do this step by step:

Step 1-

Take x/2≥-4. Now multiply both sides by 2 to isolate the x variable. Multiplying x/2 by 2 removes the denominator.

Step 2-

Since we are multiplying both sides by 2, we also have to multiply -4 by 2. We get -8

Step 3-

Therefore, x≥-8

Hope that helps :)

Solve by substitution

Answers

Answer:

(1,4)

Step-by-step explanation:

Answer: x = 1, y = 4

Steps: 3y + 4x = 16,  -2x + y = 2

Isolate y for 3y + 4x = 16:   y = (16 - 4x ÷ 3)

Substitute y into the other equation (-2x + y = 2):   -2x + (16 - 4x ÷ 3) = 2

Simplify: 16 - 10x ÷ 3 = 2

Isolate x for 16 - 10x ÷ 3 = 2:   x = 1

Substitute x = 1 into  y = (16 - 4x ÷ 3):  y = 16 - 4x · 1 ÷ 3

y = 4, x = 1
