Solve for the value of m

Answers

Answer 1

Answer:

m = 7

Step-by-step explanation:

The 3 given angles lie on a straight line, thus sum to 180° , then

8m - 4 + 90 + 5m + 3 = 180, that is

13m + 89 = 180 ( subtract 89 from both sides )

13m = 91 ( divide both sides by 13 )

m = 7

Kira started a game at 4:37 PM and finished it at 5:16 PM.
How long did it take her? Give your answer in minutes.

Answers

Answer:

Step-by-step explanation:

4:37 till 5:00 is 23 minutes.

+ 16 minutes

= 23 + 16

Answer:

39 minutes

Step-by-step explanation:

First, find how much time passed between 4:37 PM and 5 PM.

Since there are 60 minutes in an hour, subtract 37 from 60:

60 - 37

= 23

There are 16 minutes in between 5 PM and 5:16 PM.

So, add the 23 minutes to 16:

23 + 16

= 39

So, it took her 39 minutes

8x = 10x + 20

Could you guys explain as well?

Answers

Answer:

x= -10

Step-by-step explanation:

-8x+10x+20=0

2x+20=0

2x=0-20

2x=-20

x=-20/2

x= -10

Answer:

x = -10

Step-by-step explanation:

8x (-10x)= 10x +20 (-10x)

subtract 10x from both sides of the equation

-2x/-2 = 20/-2

divide both sides by -2

x = -10

10 + 6x = 15 + 9x – 3x

Answers

Answer:

No solution

Step-by-step explanation:

Step 1: Write equation

10 + 6x = 15 + 9x - 3x

Step 2: Solve for x

Combine like terms: 10 + 6x = 15 + 6xSubtract 6x on both sides: 10 ≠ 15

Here, we see that x would equal no solutions. You can also think of it as parallel lines; they have the same slope but different y-intercepts, so they will never intersect.

write a paragraph proof for the following conjecture
Given m∠1 + m∠2 = m∠4
Prove: m∠3 + m∠1 + m∠2 = 180°

Answers

m∠1 + m∠2 = m ∠4 , under the exterior angle property of a triangle which says that sum of the interior opposite angles of an exterior angle will be equal to the measure of the exterior angle .

To prove that m∠3 + m ∠1 + m∠2 = 180° , let us use the angle sum property .

= Angle sum property = Sum of the three interior angles in a triangle will be equal to 180° .

= Since ∠1 , ∠2 and ∠3 are the interior angles of this triangle , their sum will be equal to 180° .

Hence proved that m∠1 + m∠2 + m∠3 = 180°

∴ m∠1 + m∠2 + m∠3 = 180° under the angle sum property of a triangle .

Maya and carlos was selling cookie dough for school fundraiser customers can buy packages of chocolate-chip cookie dough and packages of gingerbread cookie dough my sold 8 packages of chocolate chip cookie dough and 12 packages of gingerbread cookie dough for a total of $374 carlos o two packages of chocolate chip cookie dough and four packages of gingerbread cookie dough for a total of $113 final cost of one package of chocolate chip cookie dough and one package of gingerbread cookie dough

Answers

Answer:

Cost of chip cookies = $17.5

Cost of ginger cookies = $19.5

Step-by-step explanation:

Assume;

Cost of chip cookies = c

Cost of ginger cookies = g

So,

Maya's sales = 8c + 12g = 374 .....Eq1

Carlo's sales = 2c + 4g = 113 .......Eq2

4 x eq2

8c + 16g = 452......Eq3

Eq 3 - Eq 1

4g = 78

g = 19.5

and

c = 17.5

Cost of chip cookies = $17.5

Cost of ginger cookies = $19.5

a student has some $1 and $5 bills in his wallet. He has a total of 17 bills that are worth $53. How many of each type of bill does he have

Answers

Answer:

$1 bills = x and $5 bills = y

x+y = 17 - that expresses the number of bills.

1x + 5y = 53.

Solve the first for x in terms of y and substitute that into the second.

x = 17 - y

17 - y + 5y =53

17 +4y = 53

4y = 36

y = 9

Substitute that back into the first equation: x + 9 = 17 and then x = 8
