Answer:
Step-by-step explanation:
<u>Given</u>
- 47 = mx + 5 ⇒ mx = 42
- 91 = nx + 7 ⇒ nx = 84
- 132 = kx + 6 ⇒ kx = 126
<u>As we see, the number x is factor of 42, 84 and 126. The two-digit factors are:</u>
- 42 = 1*42 = 2*21
- 84 = 2*42 = 4*21
- 126 = 3*42 = 6*21
<u>We have two possible solutions: </u>
<u>Proof:</u>
- 47/21 = 2 rem 5, 47/42 = 1 rem 5
- 91/21 = 4 rem 7, 91/42 = 2 rem 7
- 132/21 = 6 rem 6, 132/42 = 3 rem 6
2 (5 - 8x) - 13 = 9 (1 - x) - 12
10 - 16x - 13 = 9 - 9x - 12
10 - 13 - 16x = 9 - 12 - 9x
- 3 - 16x = - 3 - 9x
- 3 + 3 = - 9x + 16x
0 = 7x
0/7 = x
0 = x

Hello from MrBillDoesMath!
Answer:
4600 patients
Discussion:
The word "increased" means augmented, made larger, or added to, so the question is asking us to evaluate
4400 + 200
= 4600
Column wise:
4400

Answer:
Perimeter = 28.84 m
Step-by-step explanation:
Since the other two points will make the shape to look like a square, each length of the square will be equal.
We can therefore find the length PQ by using the formula
L = sqrt ( [ X2 - X1 ]^2 + [ Y2 - Y1 ]^2
L = sqrt( [ -2 + 4 ]^2 + [ 4 + 3]^2
L = sqrt (4 + 49)
L = sqrt (52)
L = 7.2 m
Each length of the square is 7.2 m approximately
The parimeters will be:
Perimeter = 4L
Perimeter = 4 × 7.2
Perimeter = 28.84 metres
Therefore, the perimeter of the square is 28.84
