Answer:

34

Step-by-step explanation:

We can solve this equation by giving Sara's number a variable.

Let it be x.

Then we solve by simply interpreting the problem step by step.

"If you subtract 14 from my number..."

x - 14

"...and multiply the different by -4..."

-4(x-14)

"...the result is -80"

-4(x-14) = -80

Now that we have our equation, we can solve for x.

1.) Use distributive property to expand.

-4x + 56 = -80

2.) Subtract 56 from both sides

-4x = -136

3.) Divide by -4

x = 34

Sara's number is 34

$\bf h=20ln(3t+2)+30\\\\
-------------------------------\\\\
\boxed{a}\\\\
\stackrel{0~years}{t=0}\qquad h=20ln[3(0)+2]+30\implies h=20ln(2)+30
\\\\\\
h\approx 43.86
\\\\\\
\boxed{b}\\\\
\stackrel{1~meter}{h=100}\qquad 100=20ln(3t+2)+30\implies 70=20ln(3t+2)
\\\\\\
\cfrac{70}{20}=ln(3t+2)\implies \stackrel{\textit{log cancellation rule}}{e^{\frac{7}{2}}=e^{ln(3t+2)}}\implies e^{\frac{7}{2}}=3t+2
\\\\\\
e^{\frac{7}{2}}-2=3t\implies \cfrac{e^{\frac{7}{2}}-2}{3}=t\implies 10.371817\approx t$

$\bf \boxed{c}\\\\
\cfrac{dh}{dt}=20\left(\cfrac{1}{3t+2}\cdot 3 \right)+0\implies \cfrac{dh}{dt}=20\left(\cfrac{3}{3t+2} \right)\\\\\\ \cfrac{dh}{dt}=\cfrac{60}{3t+2}
\\\\\\
\left. \cfrac{dh}{dt} \right|_{3}\implies \cfrac{60}{3(3)+2}\implies \cfrac{60}{11}
\\\\\\
\left. \cfrac{dh}{dt} \right|_{10}\implies \cfrac{60}{3(10)+2}\implies \cfrac{15}{8}$

write a division problem thaty has a 3 digit dividend and A DIVISOR BETWEEN 10 AND 29. show how to solve it

Mashutka [201]

First we think of a 3 digit dividend for example 100.
Next we think of a divisor between 10 and 29 for example 20.
We divide 100÷20=5

Here's a division problem:

Sophia has 100 pencils. She has 20 boxes with the same number of pencils in them. How many pencils does Sophia put her box?

Divide 100 by 20 which equals 5

Your answer is 5
