Regroup terms

p/7 - 3 = -5

Add 3 to both sides

p/7 = -5 + 3

Simplify -5 + 3 to -2

p/7 = -2

Multiply both sides by 7

p = -2 × 7

Simplify 2 × 7 to 14

p = -14

Step-by-step explanation:

We have to find the fractions of whole numbers.

Number 1:

$\frac{1}{5}$ of 10 = $\frac{1}{5} \times (2 \times 5) = 2$ (Answer)

Number 2:

$\frac{2}{3}$ of 9 = $\frac{2}{3} \times (3 \times 3) = 2 \times 3 = 6$ (Answer)

Number 3:

$\frac{7}{8}$ of 32 = $\frac{7}{8} \times (4 \times 8) = 7 \times 4 = 28$ (Answer)

Number 4:

$3 \times 10^{2} + 5 \times 10^{1} + 8 \times 10^{0} + 1 \times \frac{1}{10^{2} }$

= $3 \times 100 + 5 \times 10 + 8 \times 1 + \frac{1}{100}$ {Since $a^{0} = 1$ }

= 300 + 50 + 8 + 0.01

= 358.01 (Answer)

Together, the areas of the rectangles sum to 30 square centimeters.

Juli2301 [7.4K]

Answer:

3x+2y

Step-by-step explanation:

Find the rectangles attached

Area of a rectangle = Length * Width

A = A1+A2

given

A = 30cm²

A1 = 3 * x

A1 = 3x

A2 = 2*y

A2 = 2y

Substitute

30 = 3x+2y

Hence the required equation is 3x+2y = 30

If dy/dt=-2y and if y=1 when t=0, what is the value of t for which y=1/2

gladu [14]

$\bf \displaystyle \int -2t\cdot dt\implies -2\int t\cdot dt\implies -2\cdot \cfrac{t^2}{2}+C
\\\\\\
-t^2+C=f(x)\qquad 
\begin{cases}
f(x)=y=1\\
t=0
\end{cases}\implies -0^2+C=1\implies C=1
\\\\\\
-t^2+1=f(x)\\\\
-----------------------------\\\\
-t^2+1=f(x)\qquad f(x)=\cfrac{1}{2}\implies -t^2+1=\cfrac{1}{2}
\\\\\\
1-\cfrac{1}{2}=t^2\implies \pm \sqrt{\cfrac{1}{2}}=t\implies \cfrac{1}{\pm \sqrt{2}}=t
\\\\\\
\pm \cfrac{\sqrt{2}}{2}=t\impliedby \textit{with a rationalized denominator}$

I WILL GIVE BRAINLIEST ONLY IF YOUR CORRECT

Shalnov [3]

Answer: C) 7.5 feet

Step-by-step explanation:

1. You know that the triangles are similar. Therefore, to calculte the lenght of her puddle (which is identified in the figure as l ), you can set up the following proportions:

$\frac{l}{5ft}=\frac{12ft}{8ft}$

2. Now, you must solve for l. Then you obtain that the result is:

$l=\frac{(5ft)(12ft)}{8ft}\\l=7.5ft$

3. The answer is the option C.
