Answer:

I think its 13

Step-by-step explanation:

because the line above it which is 18 looks like the same length. So I would subtract 5 from 18 to get 13. because 13+5 is 18. Good luck!!

Which expressions are equivalent to 28?

alexgriva [62]

$\huge\text{Hey there!}$

$\huge\text{Finding out what is \bf equivalent to 28}$

$\large\textsf{980 - 35}\\\large\textsf{= 945}\\\large\textsf{945 }\neq\large\textsf{ 28}$

$\large\textsf{480 - 16}\\\large\textsf{= 464}\\\large\textsf{480 }\neq\large\textsf{ 28}$

$\large\textsf{1,400 + 50}\\\large\textsf{= 1,450}\\\large\textsf{1,450}\neq\large\textsf{ 28}$

$\large\textsf{625 - 250}\\\large\textsf{= 375}\\\large\textsf{375 }\neq\large\textsf{ 28}$

$\large\textsf{1,680 + 60}\\\large\textsf{= 1,740}\\\large\textsf{1,740 }\neq\large\textsf{ 28}$

$\huge\text{Thus, your answer is: \boxed{\textsf{none of the above}}}\huge\checkmark$

If you want to buy an item in a store that costs $15 and is on sale for 15% off, then how much would the item actually cost you

scoray [572]

Answer:

It would cost you $12.75.

Step-by-step explanation:

Model an equation, using c as the initial cost variable and x as the final cost, and then solve for x.

$x = \frac{100 - 15}{100} c \\ x = \frac{85}{100} (15) \\ x = \frac{17}{20} (15) \\ x = \frac{17}{4} (3) \\ x = \frac{51}{4} \\ x = 12.75$

In triangle ABC, ∠ABC=70° and ∠ACB=50°. Points M and N lie on sides AB and AC respectively such that ∠MCB=40° and ∠NBC=50°. Find

Sever21 [200]

Answer:

∠NMC = 50°

Step-by-step explanation:

The interpretation of the information given in the question can be seen in the attached images below.

In ΔABC;

∠ A + ∠ B + ∠ C = 180° (sum of angles in a triangle)

∠ A + 70° + 50° = 180°

∠ A = 180° - 70° - 50°

∠ A = 180° - 120°

∠ A = 60°

In ΔAMN ; the base angle are equal , let the base angles be x and y

So; x = y (base angle of an equilateral triangle)

Then;

x + x + 60° = 180°

2x + 60° = 180°

2x = 180° - 60°

2x = 120°

x = 120°/2

x = 60°

∴ x = 60° , y = 60°

In ΔBQC

∠a + ∠e + ∠b = 180°

50° + ∠e + 40° = 180°

∠e = 180° - 50° - 40°

∠e = 180° - 90°

∠e = 90°

At point Q , ∠e = ∠f = ∠g = ∠h = 90° (angles at a point)

∠i = 50° - 40° = 10°

In ΔNQC

∠f + ∠i + ∠j = 180°

90° + 10° + ∠j = 180°

∠j = 180° - 90°-10°

∠j = 180° - 100°

∠j = 80°

From line AC , at point N , ∠y + ∠c + ∠j = 180° (sum of angles on a straight line)

60° + ∠c + ∠80° = 180°

∠c = 180° - 60°-80°

∠c = 180° - 140°

∠c = 40°

Recall that :

At point Q , ∠e = ∠f = ∠g = ∠h = 90° (angles at a point)

Then In Δ NMC ;

∠d + ∠h + ∠c = 180° (sum of angles in a triangle)

∠d + 90° + 40° = 180°

∠d = 180° - 90° -40°

∠d = 180° - 130°

∠d = 50°

Therefore, ∠NMC = ∠d = 50°
