Answer:
m = -3m+3n/-2b
Step-by-step explanation:
Slope is expressed as;
m = y2-y1/x2-x1
Given the coordinates (a+b,4m-n) and (a-b,m+2n)
m = (m+2n)-(4m-n)/(a-b)-(a+b)
m = m+2n-4m+n/a-b-a-b
m = m-4m+2n+n/a-a-b-b
m = -3m+3n/-2b
Hence the required slope is m = -3m+3n/-2b

If $30 is shared between Deidra and Matthew at a ratio of 2:3 when Deidra got $12 how much will Matthew get?? please help
Answer:
Matthew gets $18
Step-by-step explanation:
Since Deidra got $12, and they split the $30, Matthew will get $30-$12, or $18. You can also check your answer by finding that 12:18 is in fact a ratio of 2:3 by dividing both sides by 6.

Answer:
13) cos D = 0.4706
14) cos G = 0.28
15) cos M = 0.6667
Step-by-step explanation:
13) Cos D = 8/17 = 0.4706
14) GI² = 7² + 24²
GI² = 49 + 576 = 625
GI = 25
cos G = 7/25 = 0.28
15) MN² = 3²- (√5)²
MN² = 9 - 5 = 4
MN = 2
cos M = 2/3 = 0.6667

Epositas $545,680 pesos en una cuenta que ofrece pagar 2.25.% semestral durante año y 10 meses a) ¿Cuánto recibirás en total al final del plazo?
Responder:
$ 555,911.5
Explicación paso a paso:
Dado
Principal = $ 545,680
Interés = 2,25%
Tiempo = 10 meses = 10/12 años
Debemos buscar la cantidad después de 10 meses.
Monto = Principal + Intereses
Interés = PRT / 100
Interés = 545,680 * 2,25 * 10/1200
Intereses = 12,277,800 / 1200
Interés = 10.231,5
Cantidad = 545,680 + 10,231.5
Cantidad = 555,911.5
por lo tanto, la cantidad después de 10 meses es $ 555,911.5

Part A: What was the temperature on Thursday at 5:00 a.m.? Explain or show how you got your answer.
The temperature on Thursday at 5:00 a.m. was_______.
Part B: By how much did the temperature increase on Thursday between 5:00 a.m. and 5:00 p.m.? Explain or show how you got your answer.
The temperature increased _______ degrees on Thursday between 5:00 a.m. and 5:00 p.m.
Answer:
-7*F, and the temperature increased by 34*F

75% of the value is $45.
100% of the value is=45×100/75=$60
Therefore, the original price of the jacket is $60.

Dana bought 12 pizzas for a Math Club party. Some were pepperoni pizzas that $11.00 each,
and the rest were mushroom pizzas that cost $9.50 each. She paid $124.50 for the pizzas. How
many pepperoni pizzas did she buy
Answer:
7 pepperoni pizzas
Step-by-step explanation:
First, you take the biggest number and subtract it by 9.5 until you get a number that can be divided into 11 which is 77.
Answer:
7 pepperoni pizzas
Step-by-step explanation:
Where p = # of pepperoni pizzas and m = # of mushroom pizzas
124.50 = 11p + 9.5m
Now you need to guess and check:
Use this equation: (124.5 - 11 * p) / 9.5 and replace p with whole numbers until you get a whole number as the output
I got p=7 and m=5
So she bought 7 pepperoni pizzas
