Answer:

4w +7 = 5

Step-by-step explanation:

Have a nice day.

Answer:

4w + 7 = 5

Step-by-step explanation:

"sum" means addition (+), so we're to add two items:

item 1 to be added

"4times a number" means multiplication(x) of 4 and w(because w stands for the unknown number).

Therefore, 4 x w = 4w

item 2 to be added

This is the number 7

The sum

4w + 7

Now, the sum, equals(=)  the number 5, therefore answer:

4w + 7 = 5

Answer:

im gonna assume the 10 - 20 is what the equation is = to if not x wouldnt be = to anything x = -1.5

Step-by-step explanation:

-2.25x + 8.75x = 10-20

-2.25x+ 8.75x = -10

6.50x = -10 divide both sides by 6.5

x = -1.5

Answer:

= 5/29

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

    = ( 8-3)/(13 - -16)

    = ( 8-3)/( 13+16)

   = 5/29

Given:

Length of a rectangular monitor screen is 5 in more than it's width.

If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².

To find:

The length and width of the screen.

Solution:

Let width of the screen be x inches.

Length of a rectangular monitor screen is 5 in more than it's width. So,

Length of screen = (x+5) inches

Area of screen is

[tex]Area=length\times width[/tex]

[tex]A_1=(x+5)\times x[/tex]

[tex]A_1=x^2+5x\text{ in}^2[/tex]

If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².

New length = 2(x+5) inches

New width = (x-1) inches

So, new area is

[tex]A_2=2(x+5)(x-1)[/tex]

[tex]A_2=(2x+10)(x-1)[/tex]

[tex]A_2=2x^2+10x-2x-10[/tex]

[tex]A_2=2x^2+8x-10 \text{ in}^2[/tex]

Area increased by  170 in².

[tex]A_2-A_1=170[/tex]

[tex](2x^2+8x-10)-(x^2+5x)=170[/tex]

[tex]2x^2+8x-10-x^2-5x=170[/tex]

[tex]x^2+3x-10=170[/tex]

Subtract 170 from both sides.

[tex]x^2+3x-10-170=0[/tex]

[tex]x^2+3x-180=0[/tex]

Splitting the middle term, we get

[tex]x^2+15x-12x-180=0[/tex]

[tex]x(x+15)-12(x+15)=0[/tex]

[tex](x+15)(x-12)=0[/tex]

[tex]x=-15,12[/tex]

Width cannot be negative. So, x=12.

Width = 12 inches

Length = 12+5 = 17 inches

Therefore, the length of screen is 17 inches and width is 12 inches.

Step-by-step explanation:

I am in 8th grade and we do these problems for honors algebra and if you add (8.5q+1.6r)+(3.5q-4.1s)+(4.4s+5.8r) you will get the answer above

Answer:

Thank you ☺️☺️

Lets solve your equation step-by-step

2(x+3)=x-4

Step 1 :Simplify both sides of the equation

2(x+3)=x-4

(2)(x)+(2)(3) =x+-4 (distribute)

2x+6=x+-4

2x+6=x-4

Step 2: Subtract x from both sides

2x+6-x=x-4-x

x+6=-4

Step 3: Subtract 6 from both sides

x+6-6=-4-6

Answer:

Triangle ABC is not a right triangle because d) it doesn't have a pair of perpendicular sides

Step-by-step explanation:

Perpendicular sides mean that the slopes are "opposite reciprocals" of each other.

Example: slope is 1/2 and the perpendicular line's slope is -2

How? 1/2 changes to 2 (you flip it, reciprocal), and then from 2 to -2 (apply opposite sign)

So when you calculate the slopes of AB, AC, and BC, none of their slopes are opposite reciprocals of each other. You can calculate the slopes of each and compare them if you want to check.

I really hope this helps, do you think you can tell me if you got the answer correct? I'd feel really bad if you got it wrong because of me. All I know is that it's not a right triangle.

Answer:

x = 14

Step-by-step explanation:

These angles are complementary angles, meaning they have a sum of 90°.

4x + 1 + 2x + 5 = 90

6x + 6 = 90 (Added like terms.)

6x = 84 (Subtracted 6 on both sides.)

x = 14 (Divided 6 on both sides.)

[tex]\sf \longmapsto \: (4x + 1) + (2x + 5)[/tex]

[tex]\sf \longmapsto \: 4x + 1 + 2x + 5 = 90[/tex]

[tex]\sf \longmapsto4x + 2x + 1 + 5 = 90[/tex]

[tex]\sf \longmapsto6x + 6 = 90[/tex]

[tex]\sf \longmapsto6x = 90 - 6[/tex]

[tex]\sf \longmapsto \: 6x = 84[/tex]

[tex]\sf \longmapsto \: x = \cancel\dfrac{84}{6} [/tex]

[tex]\sf \longmapsto \: x = 14[/tex]

Answer:

You must produce 12 units

Step-by-step explanation:

19.35 - 9.75=9.60

9.6/0.8=12

Answer:

the answer is 12 units  

Step-by-step explanation:

u get 9.75 an hour and 0.80 for every unit so subtract 9.75 from 19.35 and u get 9.60 now divide that by 0.80 and u  get 12 units

Answer:

(8, 0 )

Step-by-step explanation:

Given the 2 equations

y = 8 - x → (1)

y = 5x - 40 → (2)

Substitute y = 5x - 40 into (1)

5x - 40 = 8 - x ( add x to both sides )

6x - 40 = 8 ( add 8 to both sides )

6x = 48 ( divide both sides by 6 )

x = 8

Substitute x = 8 into either of the 2 equations and solve for y

Substituting into (1)

y = 8 - 8 = 0

Solution is (8, 0 )

Answer:

x = - 4

Step-by-step explanation:

Given

[tex]\frac{5}{3}[/tex] x + 4 = [tex]\frac{2}{3}[/tex] x

Multiply through by 3 to clear the fractions

5x + 12 = 2x ( subtract 2x from both sides )

3x + 12 = 0 ( subtract 12 from both sides )

3x = - 12 ( divide both sides by 3 )

x = - 4

Answer:

The slope IS NOT 3.

So the statement is FALSE.

Step-by-step explanation:

y = mx + b

If we change the graph shown into the format shown above it would be:

y = 1x - 3

mx = slope

Slope = 1x

b = y-intercept

b = -3

To find the slope you must do:

[tex]\frac{y}{x} =\frac{RISE}{RUN}[/tex]

y = rise

x = run

In the graph shown, the points are going up and shift to the right 1 unit.

So the slope is: 1x

Therefore, the statement, "The slope is 3" is actually false.
