Answer:

−9.661

Step-by-step explanation:

Let's substitute \blueD{a = 6.05}a=6.05start color #11accd, a, equals, 6, point, 05, end color #11accd and \maroonD{b = 3.611}b=3.611start color #ca337c, b, equals, 3, point, 611, end color #ca337c into the expression.

\begin{aligned} &\phantom{=} -\blueD{a}+(-\maroonD{b}) \\\\ &= -\blueD{6.05}+\left(-\maroonD{3.611}\right) \end{aligned}  

​  

 

=−a+(−b)

=−6.05+(−3.611)

​  

=−6.05−3.611

Answer: -9.66

Step-by-step explanation:

Here the given expression,   -a + (-b)

Where  a = 6.05 and b =3.61

By putting the given values of a and b in the given expression,

We get,

- 6.05 + ( -3.61)

= -6.05 - 3.61

= - (6.05 + 3.61)

= - 9.66

The area of a rectangle is x 2 – 3x – 28. If the<br><br>length is x + 4, find the width.
Hatshy [7]

Answer:

-4 square units

Step-by-step explanation:

a = l × b

x2 - 3x - 28 = (x +4)(×)

x2 - 3x - 28 = x2 + 4x

-3x - 28 - 4x = 0

-7x - 28 = 0

-7x = 28

x = -4

Carlos and Maria drove a total of 233 miles in 4.4 hours. Carlos drove the first part of the trip and averaged 55 miles per hour
11Alexandr11 [23.1K]
So basically
D=RT
distance=rate times time

D=233
carlos speed=55
maria speed=50
total time=4.4 hours

so therefor we have to represent
carlos time
maria time
carlos distance
maria dstance

let's say that
remember that whatever carlost drove is 233 minus maria (time and distance)
and since we are solving for maria time and distnace, solve in terms of them
maria time=t
maria distance=d
carlos time=4.4-t
carlos distance=233-d

remember total D=RT
find their seperate equations
carlos
233-d=55(4.4-t)

maria
d=50(t)
use them to solve

233-d=55(4.4-t)
subsitute 50(t) for d
233-50t=55(4.4-t)
add 50t to both sides
233=55(4.4-t)+50t
distribute using distributiver protperty (a(b+c)=ab+ac)
55(4.4-t)=242-55t
233=242-55t+50t
add like terms
233=242-5t
add 5t to both sides
233+5t=242
subtract 233 from both sides
5t=9
divdie both sides by 5
t=1.8
maria drove 1.8 hours

the answer is A

How much heat in kJ is released when nitrogen and hydrogen react as below to form 100.g ammonia heat equals-92.2kj
tresset_1 [31]

100g of ammonia releases 271.18 kJ of heat.

<u>Explanation:</u>

Given:

N₂ reacts with H₂

The reaction is:

2N₂ + 3H₂ → 2NH₃ + 92.2 kJ

According to the balanced reaction:

2 X 17g of ammonia releases 92.2 kJ of heat

34g of ammonia releases 92.2 kJ of heat

100g of ammonia will release = \frac{92.2}{34} X 100 kJ of heat

                                                 = 271.18 kJ

Therefore, 100g of ammonia releases 271.18 kJ of heat.

use the distributive property to remove parentheses. Simplify your answer as much as possible. 1/2(4y+7)
Anna007 [38]
1/2(4y+7)

Use the distributive property. a(b+c)= ab+ac 

1/2*4y= 2y

1/2*7= 3.5

2y+3.5 <---- simplified expression

I hope this helps!
