Answer: X = 42
Steps:
(3x + 12) + x = 180
3x + 12 + x = 180
4x + 12 = 180
4x = 180 - 12
4x = 168
x = 168/4
x = 42
Check:
(3x + 12) + x = 180
3x + 12 + x = 180
3(42) + 12 + 42 = 180
126 + 12 + 42 = 180
180 = 180 ✅
I would appreciate the brainliest if this was correct and had helpful & clear steps! :)
Answer:
a. 32,2°C
b. 131 °F
c. -28,9°C
Step-by-step explanation:
We must consider the following formula:
(x-32) × 5/9 = y , where x= temperature in °F an y= temperature in °C
Then,
a) In the formula we replace x=90° F, and we have: y = (90-32)× 5/9 = 32,2 °C
b) In the formula we replace y=55° C, and we have: 55 = (x-32)× 5/9 ⇒ 55×9/5 =x-32 ⇒ x=(55×9/5)+32 = 131 °F
c) In the formula we replace y= -20° C and we have: -20 = (x-32)× 5/9 = -4°F

24+16= 40
24-16=8 if it's wrong, try and make ur question more specific, thanks
Answer:
10 Sour Candies
Step-by-step explanation:
First you have to figure out the cost of the peppermints
9 x 0.25 = 2.25
Now figure out how much money Samantha has left over
6.00 - 2.25 = $3.75
Divide that amount by 0.35 (sour candy cost)
3.75 / 0.35 = 10.7
Assume that the store does not sell 0.7 of a candy, and you have

Answer:
y = 3
Step-by-step explanation:
The slope formula can be used to find the slope of the parallel line.
m = (y2 -y1)/(x2 -x1)
m = (1 -1)/(7-(-2)) = 0
The line is a horizontal line, so the y-intercept must be chosen to match the y-value of the given point.
y = 3
_____
If you want to see the slope of zero in the slope-intercept form equation, you can write the equation as ...
y = 0x +3
It is pretty unusual to keep 0 terms in an equation. Usually, they are eliminated when the equation is simplified.
