Answer:
22 kids
Step-by-step explanation:
R (red shirts)
Y (yellow shirts)
R= Y+12 (to make them equal, you need to add 12 to the yellow because it tells you that there are 12 more red shirts than yellow)
R+Y=32 (the amount of students in the class)
Substitute R from the first equation into the second one.
(Y+12) + Y = 32
2Y +12 =32 (subtract 12 from both sides)
2Y =20 (divide by 2 on both sides)
Y=10
Now you know the amount of kids wearing yellow shirts.
Subtract the whole class and the yellow shirts.
32-10= 22
Answer:
SSS
Step-by-step explanation:
I think
Y = -3
T = -4
7x - 14
X = 4
We just need to add the 2 numbers together to find the balance at the end of Wednesday.
-90+100
=10
She had $10 at the end of Wednesday in her bank account.
The area of the circle is 3.14 square millimeters
<h3>Calculating Area</h3>
From the question, we are to the area of the circle
The area of a circle can be determined by using the formula,
A = πr²
Where A is the area of the circle
and r is the radius of the circle
From the given information,
r = 1 mm
and π = 3.14
Putting the parameters into the equation, we get
A = 3.14 × 1²
A = 3.14 × 1
A = 3.14 mm²
Hence, the area of the circle is 3.14 square millimeters
