For which of the following is x = 5 NOT a solution
(a) 12 + 3x = -15
(b) 2x − 6x = -20
(c) 18 = 13 + x
(d) -4x = x − 25

Answers

Answer 1

Answer:

A) x= -9

B) x=5

C) x=5

D) x=5

Step-by-step explanation:

Answer 2
the first one, if you plug in 5 to the others, they come out even. A does not.

12 + 3(5) = -15
12 + 15 = -15
27 = -15
0 = -42

this is incorrect, making A your answer.
hope this helps!

.A 15 m ladder rests against a wall at an angle of 60° with the ground. How far is the
foot of the ladde from the wall?

Answers

9514 1404 393

Answer:

  7.5 m

Step-by-step explanation:

The cosine relation applies.

  Cos = Adjacent/Hypotenuse

  cos(60°) = (distance to wall)/(15 m)

  distance to wall = (15 m)cos(60°) = (15 m)(1/2) = 7.5 m

The foot of the ladder is 7.5 m from the wall.

find the difference
1. 4-3/5
2.5-4/7
3.6-2/3
4.5-7/8
5.7-2/5​

Answers

1) with 3/5 as a fraction one whole number can be written as 5/5

so you could rewrite 4 as 3 and 5/5 now subtract 3/5 and you are left with

3 and 2/5

2) one whole number can be written as 7/7

Now you have 4 and 7/7 minus 4/7 to get 4 and 3/7

Using the same steps for the rest:

3) 5 and 3/3 -2/3 = 5 and 1/3

4) 4 and 8/8 - 7/8 = 4 and 1/8

5) 6 and 5/5 - 2/5 = 6 and 3/5

The measure of the angle G will be equal to 27.50°.

What is trigonometry?

The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry. The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.

Given that in ΔFGH, f = 880 inches, g = 450 inches, and h=890 inches.

The value of the angle G will be calculated as,

g² = h² + f² -2hfcosG

450² = (890)² + (880)² - 2(890)(880)cosG

202500 = 792100 + 774400 + 1566400cosG

cosG = ( 1364000) / ( 12 x 890 x 880 )

cosG = 0.87

G = cos⁻¹(0.87)

G = 27.50°

Therefore, the measure of the angle G will be equal to 27.50°.

2: Base is 25/2 (12 1/2)

3: Height is 59/4 (14 3/4)

Step-by-step explanation:

Since the formula to find the area of a pallelogram is A=base × height

I divided the area by either the Base or the height (depending which one the problem had gave me)

Therefore 147 will be divided by 15 3/4.

Then 140 5/8 will be divided by 11 1/4.

Finally 151 3/16 would be divided by 10 1/4.

A membership to a movie night club costs $10 plus $2 per movie. Write the equation in slope intercept form to represent the situation

Answers

y=2x+10 so the y intercept is 10 and the slope is 2

The equation in slope-intercept form is y = 2x + 10.

Option A is the correct answer.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Cost of membership = $10

Cost per movie = $2

The total cost for x movie.

= 10 + 2x

This can be written as,

y = 2x + 10

This is a slope-intercept form.

Where 2 is the slope.

Thus,

The equation is y = 2x + 10.

Answer:
a° = 41°
b° = 139°

Explanation:
Vertical angles are opposite angles created by a pair of intersecting lines, and are equal in measure.
Angle a° is a vertical angle with the angle created by D and B.
a° = ∠DB
a° = 41°

Straight lines are 180°.
Line DC is straight and is divided into two angles, which will add to 180°.
b° + 41° = 180°
b° = 180° - 41°
b° = 139°

Answer:

a° = 41°

b° = 139°

Step-by-step explanation:

a° = ∠DB

a° = 41°  

b° + 41° = 180°

b° = 180° - 41°

b° = 139
