Answer:

Step-by-step explanation:

$4a+7\leq35\qquad\text{subtract 7 from both sides}\\\\4a+7-7\leq35-7\\\\4a\leq28\qquad\text{divide both sides by 4}\\\\\dfrac{4a}{4}\leq\dfrac{28}{4}\\\\a\leq7$

a $\leq$ 7

because 4a + 7 - 7 $\leq$ 35 - 7

equals 4a $\leq$ 28

and 4a/4 $\leq$ 28/4

equals a $\leq$ 7

QUICK HELP: The population of the Tallahassee metropolitan area was 385,639 at the end of 2017 with a growth rate of 2.73%. Usin

PSYCHO15rus [73]

Answer:

see the explanation

Step-by-step explanation:

Let

t ---> the number of years since 2017

y ---> the population of the Tallahassee metropolitan area

we have

$y=b(1+r)^t$

we have

$b=385,639\ people$ ---> initial value or y-intercept (population for t=0)

$r=2.73\%=2.73/100=0.0273$

substitute the given values

$y=385,639(1+0.0273)^t$

$y=385,639(1.0273)^t$

For the year 2025

we have

$t=2025-2017=8\ years$

substitute in the formula

$y=385,639(1.0273)^8$

$y=478,635\ people$

Arthur earned $136 in three weeks. he goes back to school in one more week. he needs at least $189 to buy the new coat that he w

oksian1 [2.3K]

Answer: $53

Step-by-step explanation:

Given: Earning of Arthur in three weeks = $136

Let x be the money he earn in one more week.

If he needs at least $189 to buy the new coat that he wants for school.

Then it gives the inequality $136+x\geq 189$

Subtract 136 from both sides of the inequality, we get

$x\geq 189-136\\\Rightarrow\ x\geq 53$

Hence, Arthur must earn $ 53 in the next week.

It takes 636363 minutes for 444 people to paint 999 walls. how many minutes does it take 777 people to paint 444 walls? minutes

Alex777 [14]

Let t=time, p=people, and w=walls.

We know that the time it takes is directly proportional to the length of the wall but inversely proportional to the number of people working. That is
$t=k\cdot \frac{w}{p}$

We solve for the constant of proportionality, k.
$k=\frac{t\cdot p}{w}$

The initial values for k are the same for the final values. That is
$\frac{t_1\cdot p_1}{w_1}=\frac{t_2\cdot p_2}{w_2}$

$\frac{63\cdot 4}{9}=\frac{t_2\cdot 7}{4}$

$t_2=\frac{4\cdot 63\cdot 4}{7\cdot 9}=16$

It will take 16 minutes.
