Answer:

see explanation

Step-by-step explanation:

Since there are 3 parallel lines, then

a and 31° are corresponding angles and congruent, thus

a = 31°

b and 31° are same- side interior angles and supplementary, thus

b = 180° - 31° = 149°

c and b are vertical angles and congruent, thus

c = 149°

d and 31° are alternate angles and congruent, thus

d = 31°

a = 31°, b = 149°, c = 149°, d = 31°

If cheese is $4.40 per kilogram, what should i pay for 200 grams
Contact [7]
1 kg is 1,000 grams.


200 grams are 1/5 of 1000 grams, that is 1/5 of 1 kg.

Thus 200 g= 1/5 kg = 0.2 kg.



      1 kg of cheese is <span>$4.40, 
</span>
so 0.2 kg of cheese is \displaystyle{ \frac{0.2kg \cdot \$4.40}{1kg}}=4.40 \cdot0.2 \$= 0.88\$


Answer: $0.88

If ƒ(x) = x − 4 and g(x) = 3x + 5, find (ƒ + g)(x).
siniylev [52]

Answer:

(f+g)(x)=4x+1

Step-by-step explanation:

We are given the two functions:

f(x)=x-4\text{ and } g(x)=3x+5

And we want to find:

(f+g)(x)

This is equivalent to:

=f(x)+g(x)

By substitution:

=(x-4)+(3x+5)

Rearranging yields:

=(x+3x)+(-4+5)

Combine like terms:

=4x+1

Hence:

(f+g)(x)=4x+1
