Answer:
The answer is correct, here's why:
Step-by-step explanation:
Dr. Silva's tank holds 15
gallons of gas.
She added 11.55 gallons to her tank to fill it up.
This means she must have had 5
gallons to start with because 5 - 11.55 = 5
Answer:
5 1/3 x+8 1/2 =3 1/3 ?
the correct answer is -1.774
Step-by-step explanation:
51/3x + 81/2=31/3 In order to find x, we follow BODMAS rule
so we have,[ 51/3] x + 81/2 =31/3
we have 51x/3 + 81/2=31/3
we collect the like terms;
51x/3= 31/3- 81/2
finding the lcm
51x/3= 2[31} - 3{81}/6
51x/3= 62-243/6
51x/3= -181\6
by using cross multiplication
we have;
6{51x}= 3{-181}
306x = -543
divide both sides by 306
we have;
x = - 1.774
check your answer from
306x=-543
306{-1.774}= -543
-543= -543
Answer:
Whatever you do to one side you must do it to the other side of the equation.
Step-by-step explanation:
Step-by-step explanation:
a) The rule is <em><u>multiply the previous term by 6 then add 13</u></em>. So if the 1st term is n0 = -2, then the next term n1 is
n1 = 6n0 + 13
= 6(-2) + 13
= 1
n2 = 6n1 + 13
= 6(1) + 13
= 19
So the sequence goes like
-2, 1, 19
b) Now the sequence is reversed so let's write the terms as follows:
19, 1, -2
The new rule now is <em><u>subtract</u></em><em><u> </u></em><em><u>1</u></em><em><u>3</u></em><em><u> </u></em><em><u>then</u></em><em><u> </u></em><em><u>divide</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>6</u></em><em><u>.</u></em> You can check this as follows:
n0 = 19
n1 = (n0 - 13)/6
= (19 - 13)/6
= 1
n2 = (n1 - 13)/6
= (1 - 13)/6
= -2
