Answer:
x = 13
Step-by-step explanation:
These angles are vertical which means they’re EQUAL to each other:
6x + 3 = 81
6x = 81 - 3
6x = 78
x = 13
Turn 39% into a decimal
0.39
"of" means to multiply
so we get
0.39 * 72 = x
Answer:
El CD costaba $100 inicialmente.
Step-by-step explanation:
Dado que la información indica que el porcentaje de descuento es 20% y ese descuento tiene un valor de $20, puedes usar una regla de tres para encontrar el valor que representa el 100% que sería el valor inicial del CD dado que el 20% del valor es igual a $20:
20% → 20
100% → x
x=(100*20)/20=100
De acuerdo a esto, la respuesta es que el CD costaba $100 inicialmente.
3*2=6
6-x-2=0
4=x
The answer is 4
First find the decimal values of both fractions:
7/10 is 7 divided by 10 so:
= 0.70
3/5 is 3 divided by 5 so:
= 0.60
60 minutes is one hour (since the question said that Lola rides the bike for 7/10 and 3/5 of an hour)
Now we use these to find how many minutes:
To find 0.70 (or 7/10) of 60 minutes, you multiply 60 x 0.70
= 42 minutes on Saturday
To find 0.60 (or 3/5) of 60 minutes, you multiply 60 x 0.60
= 36 minutes on Sunday
Now to find how much longer she rode her bike on Saturday than Sunday, you subtract the two numbers:
42 - 36
= 6
Therefore, Lola rode her bike for 6 minutes more on Saturday than on Sunday.
