Answer:

∡3 = 142°

Step-by-step explanation:

28° + 10° + ∡3 = 180° (Sum of angles in a triangle)

38° + ∡3 = 180°

∡3 = 180° - 38°

∡3 = 142°

Alternate method:

38° + ∡3 = 180° (Sum of angles on a straight line)

∡3 = 180° - 38°

∡3 = 142°

Answer:

38 degree + 180 degree = [ sum of angle on a straight line]

3= 180 degree - 38 degree

3= 142 degree.

Someone answered another question of this. In simple words the answer is 12 dollars.

Answer:

500 miles

Step-by-step explanation:

Step one:

A car costs $3,500 and costs $4 in gas to drive fifteen miles

let the total cost be y and let the number of miles be x

y= 3500+4x-----------1

If another car costs $4,500 but only need $2 in gas to drive fifteen miles,

let the total cost be y and let the number of miles be x

y= 4500+2x----------------2

Step two:

Equate the two expressions for the total cost

3500+4x=4500+2x

solve for x

4x-2x=4500-3500

2x= 1000

divide both sides by 2

x= 1000/2

x= 500 miles

Answer:

46994

Step-by-step explanation:

x ÷ 39 = 1204 + 38

x ÷ 39 = 1204 + 38

x ÷ 39 = 1242

x ÷ 39 × 39 = 1242 × 39

x = 46994

Answer:

The answer is below

Step-by-step explanation:

1) Let x represent the price of Tacos and y represent the price of Burrito. You where charged $4.80, hence:

2x + 2y = 4.80; Dividing through by 2:

x + y = 2.4         (1)

Your friend was charged $4.00, hence:

3x + y = 4.00     (2)        

Solving equation 1 and 2 simultaneously by subtracting equation 2 from equation 1:

2x = 1.6

x = 0.80

Put x = 0.8 in equation 1:

0.8 + y = 2.4

y = 1.60

The cost of each tacos is $0.80 and the cost for each burritos is $1.60

2) Let x represent the smaller number and y the bigger number, hence:

y - x = 16        (1)

Also:

y = 4x - 5;

y - 4x = -5       (2)

Subtract equation 2 from equation 1 to solve simultaneously:

3x = 21

x = 7

Put x = 7 in equation 1:

y - x = 16

y - 7 = 16

y = 23

The greater number is 23 and the smaller number 7

Answer:

x = 13

Step-by-step explanation:

x and 167 are a linear pair, x plus 167 will equal 180

x + 167 = 180

x = 180 - 167

x = 13

To check: x + x + 167 + 167 = 360

x = 13

13 + 13 + 167 + 167 = 360

26 + 167 + 167 = 360

26 + 334 = 360

360 = 360

Answer:

[tex]x = 13[/tex]

Step-by-step explanation:

[tex]x + 167 = 180(linear \: pair) \\ x = 180 - 167 \\ x = 13[/tex]

Answer:

The rate of change is [tex]\frac{7}{4}[/tex] or 1.75. That shows that the cost per video game is $1.75

Step-by-step explanation:

The change in y over change of x or slope can be calculated using the equation:

[tex]m=\frac{y_{2} -y_{1} }{x_{2}-x_{1} }[/tex] so take the last two points: (10, 25) and (15, 33.75).

33.75-25=8.75

15-10=5

8.75/5=1.75 (7/4)

x=video games

y=total cost

Since slope is change in y (cost) per change of x (video games), the answer is:

1.75 cost per video game

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

(8 + 9) + 3 is equivalent to 8 + (9 + 3) using the property of associative.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

(8 + 9) + 3 = 17 + 3 = 20

8 + (9 + 3) = 8 + 12 = 20

This is the property of associative.

Thus,

(8 + 9) + 3 is equivalent to 8 + (9 + 3) using the property of associative.
