5x5=25 so 25 different ways
Answer:
a = 33ft
b= 66ft
c = 48 ft
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- a (shortest side)= a
- b (second side)=2a (twice the length of the shortest side)
- c (third side)= a+15 ( 15 feet more than the length of the shortest side)
Since:
Perimeter = a+b+c
Replacing with the values given:
147 = a+2a+(a+15)
147 = a+2a+a+15
147-15 = a+2a+a
132 = 4a
132/4 = a
33 ft= a
Substituting a =33 in the other expressions:
b=2a = 2(33) = 66 ft
c= a+15 = 33+15 = 48 ft
It’s not 12 or 30 so it’s 20 or 16 and I’m pretty sure it’s 16
76 out of 80 people for David.
Therefore, 76/80 people for David.
Further simplifying, every 19 out of 20 people voted for David.
What's 19 out of 20?
20 x 5 = 100
19 x 5 = 95
95% of the club members voted for David.
Answer:
Step-by-step explanation:
Okay This is what is happening...
$955 total - $435 painting= $520 doll profit
First, subtract the painting Danika sold from the total. This will give you the amount she earned from the doll collection. Then, divide by the dollar amount to give the amount of dolls sold.
$520 doll profit divided by $20 = $26 fir each doll
or
Equation: 955=435-20d
Variable: d= number of dolls sold
Solve Equation: 955=435-20d
-435=-435
955-435=435-435-20d
520=20d
/20=/20 (I used "/" as my divide sign you can use the other one)
520/20=20/20
26=d
Final Answer: 26=dolls sold
