Solve the equation using the distributive property and properties of equality

-5 (a + 3) = -55

What is the value of a?

Answer:

2w+10

Step-by-step explanation:

Answer:

Step-by-step explanation:

-3a + 6b = a + 4b

-4a + 6b = 4b

-4a = -2b

a = -2b/-4

f(a) = -b/2

Answer:

y=-5/2x-1

Step-by-step explanation:

change the equation to slope intercept form

y=-5/2x+6

graph the point (-2, 4)

use the slope of the equation to find the y intercept

y intercept = -1

write equation of the parallel line using the same slope of the first line

-5/2x

and the y intercept of the new parallel line -1

y=-5/2x-1

Answer:

x = 5

Step-by-step explanation:

5x + 17 = 42

5x = 25

x = 5

Answer:

x = 5

Step-by-step explanation:

5x+17= 42

Subtract 17 from each side

5x+17-17= 42-17

5x = 25

Divide each side by 5

5x/5 = 25/5

x = 5

Answer:

32, 24

Step-by-step explanation:

48 divided by 2 is 24 plus 8 is 32 then divide by 2 get 16 plus 8 is 24

Answer:

B. 24 and 32

Step-by-step explanation:

when you divide 48 by 2, get 24.

Then you must add 8 to 24 to get the next number, which will be 32.

Answer:

Yes, it is a right angle triangle

Step-by-step explanation:

Let leg lengths be y and z

Y = 2mm

Z = 2.1mm

Let x represent hypothenus

X = 2.9mm

To find out if it's a right angle triangle, we'll use pythagorean theorem since it's true for all right angle triangles I.e the square of the hypothenus is equal to the square of both sides(opposite and adjacent)

x² = y² + z²

x² = 2² + 2.1²

x² = 4 + 4.41

x² = 8.41

Take the square root of both sides

x = √(8.41)

x = 2.9mm

Therefore since the square of two other sides equal the square of the hypothenus, the side of the clip is a right angle triangle

Answer:

0y=2/3x+2

Step-by-step explanation:

0y=2/3x+2 (multiply the #s)

0 =2/3x+2 (move the expression to the left)

= -2/3x=2(multiply both sides by -3/2)

x=-3 (Solution)

Answer:

504 in³

Then find the volume of the small rectangle, which is 72 in³

Then subtract 72 from 576 = 504

Answer:

5*14=70

Step-by-step explanation:

Divide 28 by 2 because it is the second on the number line and because Jonah folded 2 shirts in that time. You would get 14. You then get a speed of 1 shirt every 14 seconds. That means if you multiply 5 with 14, you'd get the number of seconds it'd take for Jonah to fold her clothes. Not a nice chore I must say. Pardon my english, and hope this helps :)

Answer:

Step-by-step explanation:

In the image attached, you can observe that the angle we need to find is an acute angle of a right triangle, where its hypothenuse is 21 units long and its opposite leg is 16 units long.

Having these elements, we can use the sine trigonometric reason to find the angle.

[tex]sin(x)=\frac{opposite \ leg}{hypothenuse} =\frac{16}{21}\\ x=sin^{-1}(\frac{16}{21} ) \approx 49.63\°[/tex]

Therefore, the angle is 49.63°, approximately.

Answer:

P=100-0.18

Step-by-step explanation:

Remember, percent means per every 100. So if the car cost $100, Mr. Stanley saves $18 on the car. Also, 18%= 0.18. And just for extra, single digit percents would be expressed with an extra zero in front of it, such as 5%=0.05.

Using fraction, the sheets are a color other than red is 5.

Fraction is a "number are expressed as quotient, where numerator is divided by denominator".

According to the question,

Faith has 25 sheets of colored paper. She plans to make 15 of the cards out red paper.

[tex]\frac{15}{25}[/tex] =  [tex]\frac{3}{5}[/tex]

5 - 3 =2

Fraction 5 parts of sheets is equal to 25, 3 parts of sheet is equal to 15.

5 = 25

2 =  x

5 × 5 = 25

2 × 5  = 10

Hence, using fraction the number of sheets are a color other than red is 5.

Answer:

Step-by-step explanation:

Area of a rectangle = Length *Width

Width of the rectangular garden W = 2ft

If the length of the garden is 3 times as long as the width, then length = 3 * width i.e W = 3L

Since Area of the path A = L* W

A = (3W)W

A = 3W²

If the width is the same as x then

Area f(x) = (3x)(x)

According to kyle, the area of his path f(x) = (x + 2)(3x + 2) which is wrong because of kyle addition of 2 to each of the value of the length and width respectively which kyle shouldn't have added any value to the dimension to the garden

A system of equations is a collection of related equations

The system of equations that can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex] [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex]

The equation is given as:

[tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]

Split the above equation into 2, and set both equations to 0

[tex]12x^3 - 5x = 0[/tex]

[tex]2x ^2 + x + 6 = 0[/tex]

Replace the "0" with y, in both equations

[tex]12x^3 - 5x = y[/tex]

[tex]2x ^2 + x + 6 = y[/tex]

Rewrite the equations as:

[tex]y = 2x ^2 + x + 6[/tex]

[tex]y= 12x^3 - 5x[/tex]

Hence, [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex] can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]
