i think this is how you do them

1.4x-1is greater too equal too 7

so 4x-1=7

+1= +1

4x=8

÷4=÷4

x=2

so × greater then equal too 2

and im pretty sure the answers are just in order

Firdavs [7]

N and d are both numbers of thousands of dollars.
Thus, if n = 1, that means $1000.

Here n = d + 0.4.
Note that in C, n+0.04=n is completely wrong.
Similarly, in D, d = 0.04 = n is completely wrong.
The "combined profit amount" for Nov. and Dec. is n + d = 3.15.

Only A matches this info. Your answer is A.

Please Help, Will give Brainliest! Law Of Cosines.

stealth61 [152]

Answer:

B) a = 6.7, B = 36°, C = 49°

Step-by-step explanation:

Fill in the numbers in the Law of Cosines formula to find the value of "a".

a² = b² + c² -2bc·cos(A)

a² = 4² +5² -2(4)(5)cos(95°) ≈ 44.4862

a ≈ √44.4862 ≈ 6.66980

Now, the law of sines is used to find one of the remaining angles. The larger angle will be found from ...

sin(C)/c = sin(A)/a

sin(C) = (c/a)sin(A)

C = arcsin(5/6.6698×sin(95°)) ≈ 48.31°

The third angle is ...

B = 180° -A -C = 180° -95° -48.31° = 36.69°

The closest match to a = 6.7, B = 37°, C = 48° is answer choice B.

Write an expression for the calculation subtract 12 doubled from 132

prisoha [69]

Step-by-step explanation:

Doubled of 132 which means 2 times 132 =

Subtract 12 doubled from 132

While write the expression whatever the expression after the word from that we have to write first

So Doubled of 132 - 12

- 12 -----> This is the final expression

If we simplify the above expression we will get

264 - 12

= 252

Answer:

$y = x + 3$

Step-by-step explanation:

Y in math is usually referred as the output.

X is usually the input.

In other words,

y is 3 more greater than x.

In other words,

$y = x + 3$
