Answer:
c=13
Step-by-step explanation:
5^2+12^2=c^2
25+144=c^2
169=c^2
c=sqrt(169)
c=13
there are 9 cards left
1,2,3,4,6,7,8,9,10
the only cards that will make the sum less than 8 is 1 and 2
2/9
Answer: 2/9
Answer:
y = 5 ; x = 4
Step-by-step explanation:
Given :
5x + 6y = 50 - - - (1)
x - 6y = -26 - - - (2)
From (2)
x = - 26 + 6y
Put - 26 + 6y for x in (1)
5(-26 + 6y) + 6y = 50
-130 + 30y + 6y = 50
-130 + 36y = 50
-130 - 50 = - 36y
-180 = - 36y
y = 180 / 36
y = 5
Put y =5 in x = - 26 + 6y
x = - 26 + 6(5)
x = - 26 + 30
x = 4
y = 5 ; x = 4
Answer:
i hope this will help you
Step-by-step explanation:
a 365+94+35
=494
b 896+423+104
=1423
c 379×25×4
=45480
d 89×125×8
=89000
I) 5/30 is equal to 1/6
J) 20/35 equal to 4/7
K) 4/16 is equal to 1/4
L) 14/21 equal to 2/3
So how I got these answer is to look at the denominator or bottom number they gave u and then think what times what equals that answer for example 4/16
4x 4 =16 right! so then then what is 4 divided by 4 = 1 because what u do to the top u do to the bottom
