Answer:

10 ^(R-15)/3 -2= a

Step-by-step explanation:

R = 3 log (a+2) +15

Subtract 15 from each side

R-15 = 3 log (a+2) +15-15

R-15 = 3 log (a+2)

Divide each side by 3

(R-15)/3 = 3/3 log (a+2)

(R-15)/3 = log (a+2)

The opposite of log is to raise each side to the power of 10

10 ^(R-15)/3 = 10 ^ log (a+2)

10 ^(R-15)/3 = (a+2)

Subtract 2 from each side

10 ^(R-15)/3 -2= (a+2-2)

10 ^(R-15)/3 -2= a

Juan told Sylvia he got a $0.50 raise this week and his new hourly rate will be $10.25 an hour. Sylvia wants to know what Juan’s

zhenek [66]

Answer:

The correct answer is:

r + 0.50 = 10.25: Subtract .50 from both sides. The answer is $9.75.

This is because Juan got a $0.50 raise which means that his new rate will be $0.50 more than his original rate (r).

NUMBER 27 please!!!!!!!

Artist 52 [7]

The inequality can be:
$150x \leqslant 3000$
Now you divide both sides by 150 to get the #of boxes.

$3000 \div 150$
Lastly, x is 20. So the maximum amount of boxes that the freight elevator can hold is 20

AnnZ [28]

Well 40 divided by 5 is 8 and you don't have options so I would say 8 loads a day :)

John made a triangle with all three sides the same length, 1 \frac{2}{3} ft. What is the perimeter of the triangle?

UNO [17]

Answer:

5 ft

Step-by-step explanation:

If all sides are of the same length, we can multiply the value of one side by 3, because a triangle has three sides (and the perimeter is all sides added together), to find the perimeter.

$1\frac{2}{3}$ × 3

$1\frac{2}{3}$ can be rewritten as $\frac{5}{3}$ , so:

$\frac{5}{3}$ × $\frac{3}{1}$

$= \frac{15}{3}$

The numerator & denominator share a common factor of 3, so:

5 ft is the final answer/perimeter.

hope this helps!
