Stuart wants to find the value of 3 3/4 -2 1/3 Before Stuart can subtract, he needs to rewrite both fractions with a common denominator. Drag a number or expression into each box to show how to write equivalent fractions so the new fractions have a common denominator.

Answers

Answer:

1  21/50

Step-by-step explanation:

3 3/4 = (3/4 x 4/4) = 3 9/12

2 1/3 = (1/3 x 3/3) = 2 4/12

Let angle 1, angle 2, and angle 3 have the following relationships.
Angle 1 and 2 are acute vertical angles
Angle 3 is an obtuse angle adjacent to both angle 1 and angle 2.
What is the sum of the measure of angle 1 and the measure of angle 3?

Answers

180 degrees

Vertical angles are opposite angles that share only a vertex. Since ∠3 is adjacent to both ∠1 and ∠2, this means that ∠3 shares a side and vertex with both of these angles.
This means that ∠3 and ∠1 form a straight line; this makes them a linear pair, which makes their sum 180°.

What is the measure of the angle C?

Answers

Answer:

110

Step-by-step explanation:

the rest of that line has to equal 180 and you already have 70 20 180 - 70 = 110

8. 3(6x) + 4 = 18x+4

9. 10(xy) = 10xy

10. 5(x + y) =5x+5y

11. 2(rs) + 4(x) = 2(rs+2x)

12. 2(q) + 2(x + t) = 2(q+x+t)

13. 6(7t + 4s) = 42t+24s

find the difference. 14.3 - (-4.3)

Answers

The answer is 18.6. The double negative (minus a negative) equals a positive. So you add 14.3 + 4.3 = 18.6
14.3 - (-4.3). the negative will turn into a plus sign since a minus a negative will be positive. so, 14.3 + 4.3 = 18.6!

6) Write a system of linear inequalities that is given by the following graph.

Answers

Answer:

The system of inequalities are x - y < 1 and y < - 2 The horizontal line shown in the graph has equation y = - 2 {As it is parallel to x-axis} Now, this line is dotted and the lower portion of the graph is shaded. So, the inequality will be y < - 2 ......... (1) Again, another line is there in the graph which passes through the points (1,0) and (0,-1)So, its equation will be

⇒ y + 1 = x ⇒ x - y = 1 Now, the origin (0,0) is within shaded zone of the inequality and putting x = 0 and y = 0, we get 0 - 0 < 1 So, the equation of the inequality is x - y < 1 {As the line is dotted} Therefore, the system of inequalities are x - y < 1 and y < - 2 (Answer)
