B = boys g = girls
.................................
b + g = 195 b = 195 - g
<u>b</u> = <u>8</u>
g 7
Substitute b for 195 - g in the 2nd equation:
<u>b</u> = <u>8</u>
g 7
<u>195 - g</u> = <u>8</u>
g 7
Cross Multiply
8g = 7 . ( 195 - g )
8g = 1365 - 7g
8g + 7g = 1365
15g = 1365
g = <u>1365</u>
15
g = 91
Substitute g for 91 in one of the equations:
b + g = 195
b + 91 = 195
b = 195 - 91
b = 104
S = 104 boys.
Answer:
D
F
Step-by-step explanation:
Parallel lines are lines of equal distance apart (equidistant), that are on the same plane but they never meet
Perpendicular lines meet thus they are not parallel lines
Also, lines that intersect , meet, thus they are not parallel lines
572 rounded to the nearest 10 is 570 and 572 rounded to nearest 100 is 600.
Answer:
C: Radicals in the denominators of fractions are considered unsimplified. You need to multiply a fraction by a value that removes radicals or imaginary numbers in the denominator, which is the complex conjugate of the denominator.

Answer:
<h2> $1008</h2>
Step-by-step explanation:
We begin by calculating the amount after the 25% discount
= regular price*0.75
=£160*0.75
=$120
We then continue by calculating the the amount that must be paid when 20% VAT is added
= 120*1.20
= $144
Now Tara is going to spend 7 nights
Hence she will have to pay
144*7= $1008
