Answer:

OC. 5x + 45 + 7y + 14 - X, OE. 4x + 7y + 11

Step-by-step explanation:

Because, 5(x + 9) is 5x + 45 and 7(y + 2) is 7y + 14 and so you simplify by simplifying the like terms for example 5x - x = 4x 45 + 14 = 59 and 7y stays the same.

The expression 5(x + 9) + 7(y + 2) - x can be equivalent to 4x + 7y + 59 and 5x + 45 + 7y + 14 - x, so option B and C are correct.

A mathematical expression is made up of a statement, at least two integers or variables, and one or more arithmetic operations.

Given expression:

5(x + 9) + 7(y + 2) - x

If you simplify, you will get,

5x + 45 + 7y + 14 - x,

And as further simplified we get,

4x + 7y + 59

Therefore, the expression 5(x + 9) + 7(y + 2) - x can be equivalent to 4x + 7y + 59 and 5x + 45 + 7y + 14 - x.

Answer:

72.66 calories

Step-by-step explanation:

1. find 1g of bannana = calories

86÷100g = 0.86 calories

1g of bannana = 0.86 calories

2 find 1g of yougurt = calories

89÷100g = 0.89 calories

1g of yougurt = 0.89 calories

3. 70g of bannana= 70×0.86

= 60.2 calories

4. 14g yogurt= 14×0.89

= 12.46 calories

5. 60.2 calories +12.46 calories = 72.66 calories

Answer:

d. 2

Step-by-step explanation:

a mode is the most frequently appeared value in a set of data. in other words, the most repeated number in a set of x, y, z.

example:

2, 3, 8, 7, 8, 7, 8

number of times 2 appeared: 1

number of times 3 appeared: 1

number of times 7 appeared: 2

number of times 8 appeared: 3

the mode here would be 8, since it is the most repeated number.

Answer:

Step-by-step explanation:

To simplify this equation,

-x+10<2

-10 from both sides

-x<-8

Take out the negative

x<8

This means x is less than 8

For ≤ and ≥ , use a closed dot to indicate the number itself is part of the solution.

For < and >, use an open circle to indicate the number itself is not part of the solution.

In this case you use a open circle and becasue x is less than 8, the arrow pointing left is correct.

Answer:

x = 10, y = 7.5

Step-by-step explanation:

Given the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{AE}{AC}[/tex] = [tex]\frac{DE}{BC}[/tex], substitute values

[tex]\frac{x}{4}[/tex] = [tex]\frac{12.5}{5}[/tex] ( cross- multiply )

5x = 50 ( divide both sides by 5 )

x = 10

and

[tex]\frac{AD}{AB}[/tex] = [tex]\frac{DE}{BC}[/tex] , that is

[tex]\frac{y}{3}[/tex] = [tex]\frac{12.5}{5}[/tex] ( cross- multiply )

5y = 37.5 ( divide both sides by 5 )

y = 7.5

Answer:

x = 14.375

Step-by-step explanation:

Ok, so we know that a triangle has a total interior degree of 180°. And since we already have a 95° angle, we just need to subtract 95 from 180.

180° - 95° = 85°

Now, we already have indicators that two of the three sides are equal. And we already got the angle of the side that does not have a matching partner. So we just need to divide what we already have by 2.

85° / 2 = 42.5°

Now that we know each side is 42.5 degrees, we just need to grab our given equation and put and equal sign at the end with what we already know is the answer (since we are trying to solve for x).

(4x - 15) = 42.5

Now, let's just get rid of those useless parentheses.

4x - 15 = 42.5

Next, we just need to have the variable on its own side, all by itself. So, in order to do that, we just add 15 to both sides.

4x = 57.5

Now, for our final step, we just need to divide each side by our variables' factor (which is a positive 4). In which we get our final answer of:

x = 14.375

Answer:

x = 14.375

Step-by-step explanation:

Since 2 sides are congruent then the triangle is isosceles and the base angles are congruent, both (4x - 15)

The sum of the 3 angles in the triangle = 180°

sum the angles and equate to 180

4x - 15 + 4x - 15 + 95 = 180 , that is

8x + 65 = 180 ( subtract 65 from both sides )

8x = 115 ( divide both sides by 8 )

x = 14.375

Answer:

100°

Step-by-step explanation:

55°+25°+third angle=180°(by angle sum property)

80°+third angle=180°

third angle=180°-80°

third angle=100°

Answer:

The measure of the third angle of the triangle would be 100°.

Step-by-step explanation:

25 + 55 + x = 180

80 + x = 180

x = 180 - 80

x = 100

The ladder has 39.6 feet

Step-by-step explanation:

Length Units Conversion

To convert from meters to feet we use the relation

1 m = 3.3 ft

The ladder that Nicholas needs to repair the roof of his grandmother's hours is 12 meter long.  

Converting this length to feet we have

12 * 3.3 = 39.6 ft

The ladder has 39.6 feet

Answer: Add 5 to both sides

What is the first step needed to solve 4 over 7 the whole multiplied by x minus 5 equal negative 13?

Answer- Add 5 to both sides

(4/7)x - 5 = -13

• As mentioned above, first step would be,

adding 5 to both sides

=> (4/7)x - 5 + 5 = -13 + 5

=> (4/7)x = -8

• Now, transporting 7 from L.H.S. to R.H.S

=> 4x = -8 × 7

=> 4x = -56

• Now in the same way, transporting 4 from L.H.S. to R.H.S

=> x = (-56/4)

=> x = -14

• And in this way, or taking (Add 5 to both sides) as our first step, we find that the value of x is -14.

∴ x = -14

Answer:

y = ⅗x

Step-by-step explanation:

The line passes through the point of origin, (0, 0). This implies that the graph represents a proportional relationship between x and y. Thus, in slope-intercept form, the line of a proportional graph can be represented as y = mx.

Where,

m = slope/constant of proportionality = y/x

To write an equation for the line, let's find the slope using any of the points on the line.

Using (50, 30):

Slope (m) = 30/50 = ⅗

Plug in the value of m into y = mx

Thus, equation of the line would be:

y = ⅗x

Answer:

SSS similarity.

Step-by-step explanation:

AA, SAS, and SSA similarities means the triangle must have an angle, which it doesn't, so by process of elimination it is SSS similarity.

By AA similarity criteria, the triangle AOB is similar to the triangle COD. Therefore, option A is the correct answer.

In the given figure, two lines AB and CD are parallel.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Consider, the triangle AOB and the triangle COD.

Here, AB║CD

∠BAO=∠CDO (Alternate interior angles)

∠ABO=∠DCO (Alternate interior angles)

By AA similarity criteria ΔAOB≈ΔCOD

By AA similarity criteria, the triangle AOB is similar to the triangle COD. Therefore, option A is the correct answer.
