Easy peasy
1.
d=number of dudes
l=number of ladies
total is 55 so
d+l=55
total cost is 75 so
2d+l=75
multiply first eeuqaiton by -1 and add to second
2d+l=75
<u>-d-l=-55 +</u>
d+0=20
d=20
sub
d+l=55
20+l=55
l=35
35 ladies
2.
ratio and proportion
$87 is to 8 as is $x is to 5
87/8=x/5
times both sides by 5
435/8=x
use calculator
54.375=x
round
$54.38 recieved
3.
around the edge
means perimiter
disregard how deep the pool is
60 feet long
x wide
P=2(L+W)
P=220
220=2(60+x)
divide 2
110=60+x
minus 60 both sides
50=x
it has to be 50 feet wide
4. monthly over 5 years
1 year=12 months
12 times 5=60 months
12381/60=206.35 per month
$206.35
5.
total-food-gas-utilities=left
1624-256-125-150=1093 left
you should be able to do this one no problem
$1093 let
1. 35 ladies
2. $54.38
3. 50 feet
4. $206.35
5. $1093
Answer:
Step-by-step explanation:
<u>Finding the smaller side</u> :
⇒ P = 2(l + w)
⇒ 20 = 2(6 + w)
⇒ 6 + w = 10
⇒ w = 4 cm
<u>Finding area</u> :
⇒ 6 × 4
⇒ 24 cm²
Answer:
$49
Step-by-step explanation:
I know this because
x/140 = 35/100
cross multiply
4900 divided by 100=
$49 dollars is the discount amount.
I hope this helped you!:)
Using the y=mx+b method and y1-y2/x1-x2
it would look like this
6-10=-4
divide
2-4=-2
and m=2 (slope)
then using y=mx+b
plug n chug
6=2(2)+b
6=4+b
b=2
thus, your equation is
y=2x+2
