Answers

Answer: 11.9 and 12.5

Step-by-step explanation:

|x - 12.2| = 0.3 is telling us that x must be either 12.2 + 0.3 or 12.2 - 0.3.

Longest is (12.2 + 0.3) = 12.5

Shortest is (12.2 - 0.3) =  11.9

help please i dont know how to do this

Answers

so i’m not 100% sure but o think the anwser is 67. Basically i just saw that 49 degrees was the same in both so i figured so would 69. Now triangles equal up to 180, so i added 49 and 69 and the end result was 113. after i subtracted 113 from 180 and got 67! however i’m not sure if this is 100% correct but hope this helps!!!

Solve for y.
7v + 25 = 5(v + 7)
Simplify your answer as much as possible.

Answers

Answer:

v = 5

Step-by-step explanation:

Distribute on the left:

5 ( v + 7 )

( 5 x v ) + ( 5 x 7 )

5v + 35

7v + 25 = 5v + 35

Subtract 5v from each side:

2v + 25 = 35

subtract 25 from each side:

2v = 10

Divide each side by 2:

v = 5

solve by substitution.

Answers

Step-by-step explanation:

x+y=-4

x=-4-y--(3)

substitute (3) in (1)

5(-4-y) -3y=-4

-20-5y-3y=-4

-8y=16

y=16/-8

y=-2

substitute y in (3)

[tex]\\ \sf\longmapsto x=32[/tex]

[tex]\\ \sf\longmapsto 2x-6=2(32)-6=58°[/tex]

Answer:

58°

Step-by-step explanation:

The measure if one 2 complementary angle is 6 less than the measure of the other => x + 2x - 6° = 90°

x + 2x - 6° = 90°

3x = 90° + 6°

3x = 96°

x = 96° : 3

x = 32°

Substitution :

2x - 6°

= 2 × 32° - 6°

= 64° - 6°

= 58°

pamelia is 9 years younger than jiri. The sum of their ages is 55. What is Jiris age?

Answers

Answer: 32

Step-by-step explanation: since Jiri is 9 years older, you set an equation where x (Pamelia age) + 9. So the equation is 55= x + (x+9). You subtract 9 from both sides, then divide 46 by 2 to find the Pamelia age. To find Jiri’s age, add 9 to 23 (Pamelia age).

1 book/5 days is it a unit rate

Answers

Answer: No, it is not a unit rate

Explanation:

A unit rate is when the time value in the denominator is 1. So it would need to be "1 day" instead of "5 days" for it to be a unit rate. The term "unit" means "one".

To convert to a unit rate, we simply compute 1/5 = 0.20 to see that the unit rate is 0.20 books per day. This is the same as saying "0.20 books every 1 day", but I think the phrasing "books per day" is more common.

A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8).

y -(-8) = -6(x - 2)

y -(-8) = -6x + 12

y -(-8) + 8 = -6x + 12 + 8

y = -6x + 20

Explain why the work is not correct.

Answers

Answer:

The student should subtract 8 from each side not add 8

Step-by-step explanation:

Point slope form is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y - -8 = -6(x -2)

y+8 = -6(x-2)

Distribute

y+8 = -6x+12

Subtract 8 from each side

y+8-8 = -6x+12-8

y = -6x+4

The student should subtract 8 from each side not add 8

Answer:

y -(-8) = -6(x - 2)

y -(-8) = -6x + 12

y -(-8) + 8 = -6x + 12 + 8 (this step is incorrect as minus into minus is plus therefore when taking 8 to the right hand side we must subtract it from the left hand side

y = -6x + 20

the correct equation would be : y= -6x+4

Find the area of the following kite:

Answers

Answer:

[tex]48 cm^2[/tex]

Step-by-step explanation:

Each of the small triangles are right, so we can add up all the small triangle's areas to find the total area.

The 4-by-10 triangle: The area is [tex]4*10/2=40/2=20[/tex].

The other 4-by-10 triangle has the same side lengths and hence the same area, so the area is [tex]20[/tex].

The 4-by-4 triangle: The area is [tex]4*4/2=8/2=4[/tex].

The other 4-by-4 triangle has the same area, [tex]4[/tex].

The total area is [tex]20+20+4+4=\boxed{48} cm^2[/tex].

The density of an object is calculated using the formula D=m/v where m
is the object's mass and V is its volume. Gold has a density of 19.3 g/cm^3”. What is
the volume of an amount of gold that has a mass of 96.5 g?
*If y’all can do this and show all the work that would be awesome! I have to show work to my teacher in order for her to grade it and I have a D in her class so please help!*

Answers

To find the volume of the amount of gold, rearrange the formula algebraically:

D = m/V
Multiply both sides by V:
D(V) = m/V (V)

DV = m
Divide both sides by D to isolate V
DV/D = m/D

V = m/D (this is the formula needed for volume).

Next, substitute the given values for density and mass:

V = 96.5g/19.3g/cm^3
V = 5 cm^3

Therefore, the volume of an amount of gold that has a mass of 96.5 g is 5 cm^3.
