To solve for y we have to use the INVERSE OPERATION of addition which is subtraction Lets do it:-
y + 17 = 21
y = ?
21 - 17 = y
21 - 17 = 4
y = 4
CHECK OUR WORK:-
y + 17 = 21
y = 4
4 + 17 = ?
4 +17 = 21
We were RIGHT!!!!
So, y = 4.
Hope i helped ya!! xD
So squares have 4 congruent sides. When you plot the points (0,0) and (0,5) the side length is 5 units. We can then take 5+5+5+5 and know the perimeter is 20 units.
The formula given is:
F = 1.8C + 32
The temperature C is given as -20
So, all you have to do is plug the given C temperature in the formula to get the corresponding F temperature as follows:
F = 1.8(-20) + 32 = -36 + 32 = -4 degrees Fahrenheit
Answer:
the bottom left is wrong
Step-by-step explanation:
if u add 40+5+7/10+1/100 it'll only equal to 45.71
<em>Good luck, you'll need it :)</em>
