Answer:

y = 4

Step-by-step explanation:

8(y+4)-2(y-1)=70-3y

8y+32-2y+2=70-3y

Grouping of like terms

8y-2y+3y=70-32-2

9y=36

Divide both sides by 9

9y/9 = 36/9

9 cancels itself and 9.

y=36/9

y=4

Therefore, y = 4.

Hope it helps.

If so, mark as brainliest.

8•y+8•4+-2•y+-2•-1=70-3y
8y+32+-2y+2=70-3y
8y+-2y+32+2=70-3y
6y+34=70-3y
70-34=36
6y-3y=3y
3y=36
36/3
Y=12

Evaluate in 5. A.) 0.62 B.) 0.70 C.) 1.61 D.) 1.95

Len [333]

Answer:

option C) 1.61

Step-by-step explanation:

The question is to evaluate the natural logarithm of 5. Natural logarithms are logarithms with base e.

e is the irrational number equal to 2.71828182845904523536028747 ... (being irrational the decimals do not end and do not have a repetition period).

Logarithms are evaluated using tables or scientific calculators.

ln (5) = 1.6094379... it is also an irrational number, so it has infinite decimals with no repetition period.

So, rounding to two decimal numbers, ln (5) = 1.61, which is the option C).
