Answer:

70°C

Step-by-step explanation:

First, fill in the variable that you know (F) with 158. Now you have the equation C= 5/9 × (158 - 32). According to PEMDAS, you solve parentheses first, so you get C= 5/9 × (126). Next, you do multiplication, which is 5/9 × 126. To make it simpler, you can do 5/9 × 126/1, then you can simplify it further to 5/1 × 14/1 to get 70/1 or 70.

Answer:

70 C

Step-by-step explanation:

C = 5/9 * (F-32)

substitute F = 158

C = 5/9 ( 158-32)

Parentheses first

= 5/9 (126)

= 70

Answer:

$s\geq 36$

Step-by-step explanation:

Step 1, how many knives to buy?

The restaurant <u>already has 262 knives</u>. We can subtract this number from their needed 694 knives to find how many they still need:

$694-262=432$ knives.

Step 2, how many sets of knives?

The restaurant needs to buy 432 knives. We know the knives come in sets of 12, so <u>we can divide to find the # of packs she needs to buy</u>, determined by variable <em>s</em>.

Notice how the restaurant needs to buy a minimum of 694 knives, hence we use a greater or equal than symbol:

$\fbox{\frac{432}{12} \geq s}\\$ $s\geq \frac{432}{12}$

$s\geq 36$

Find the coordinates of C' after a reflection across the line

iragen [17]

<h3>Answer: (4,2)</h3>

==============================================================

Explanation:

C is at (0,0). Ignore the other points.

Reflecting over y = 1 lands the point on (0,2) because we move 1 unit up to arrive at the line of reflection, and then we keep going one more unit (same direction) to complete the full reflection transformation. I'll call this point P.

Then we reflect point P over the line x = 2 to arrive at the location Q = (4,2). Note how we moved 2 units to the right to get to the line of reflection, and then keep moving the same direction 2 more units, then we have applied the operation of "reflect over the line x = 2"

So we have started at C = (0,0), moved to P = (0,2) and then finally arrived at the destination Q = (4,2). This is the location of C' as well.

All of this is shown in the diagram below.
