He lowest temperature on May 15 is 2 3 as warm as the warmest temperature on May 15. The lowest temperature on May 15 is 60?F. W

yulyashka [42]

Answer:

$90^{o}F$ .

Step-by-step explanation:

Let x be warmest temperature on May 15.

We have been given that the lowest temperature on May 15 is 2/3 as warm as the warmest temperature on May 15. The lowest temperature on May 15 is $60^{o}F$ .

We can set our given information in an equation as: $\frac{2}{3}x=60$ .

Now let us solve for x by multiplying both sides of our equation by 3.

$3*\frac{2}{3}x=3*60$

$2x=180$

$x=\frac{180}{2}$

$x=90$

Therefore, the warmest temperature on May 15 was $90^{o}F$ .

Answer:

$11.80 per hour

Step-by-step explanation:

So in the first 30 hours.Julio's rate is r ( the normal hourly rate)

so in the 35 hours we divide it as 30 hours and 5 hours as

30(r) + 5 (1.4r) = 436.60

solve for r : 30r + 7r = 436.60

37r=436.60

Divide both sides by 37 : r= 11.8

Julios normal hourly rate is $11.80 per hour
