3(4+n)=18+n
distribute
12+3n=18+n
minus n both sides
12+2n=18
minus 12 both sides
2n=6
divide by 2
n=3
the number is 3
equation is
3(4+n)=18+n
Answer:
2/11
Step-by-step explanation:
6 = 2 x 3
6/11 x 1/3
= ( 6 x 1 )/( 11 x 3 )
= ( 2 x 3 x 1 )/( 11 x 3 )
Cancel 3 in both numerator and denominator.
= ( 2 x 1 )/( 11 )
= 2/11
(0.1x-22)+(0.3x-54)=90
First combine like terms
0.4x - 76 = 90
Now add 76 on both sides
0.4x = 166
Divide by 0.4 on each side to isolate x
X= 415
Answer:
Option B. 75
Step-by-step explanation:
we know that
<u>A negative correlation</u> or inverse correlation is a relationship between two variables such that as the value of one variable increases, the other decreases
we know that
For L1=150, K1=7
so
For K2=14, L2=?
we have that
L1*K1=L2*k2
substitute the values
150*7=L2*14
L2=150*7/14
L2=75
Mari bought 6 packages of tomato seeds and each package contains 24 seeds then
Seeds = (6) * (24) = 144.
Mari has a total of 144 seeds.
Mari planted a pack of seeds and has 15 germinated seeds.
144-24-15 = 105
Mari then has 105 seeds left.
Answer
C At least 100 but no more than 120 seeds will sprout
