Answer:

p=7

Step-by-step explanation:

5p-1=2p+20 first add 1 to both sides to get 5p=2p+21, then subtract 2p from both sides to get 3p=21, then divide by three to get p=7

Is the circumference of all circles about 3 times greater than their diameters. and why?

stira [4]

Answer:

<h2>Yes the circumference is about times greater than their diameters</h2>

Step-by-step explanation:

We will approach this problem by doing a check

Say the diameter of a circle is 4 cm

Hence the radius is 3 cm

We know that the circumference is $C=2\pi r$

$C=2*3.142*2= 12.57cm$

The circumference is about 3 time bigger than the diameter

Let us try another case say the diameter is 6 cm

The radius is 3 cm

$C=2*3.142*3= 18.85cm$

what is the equation subtracting 7 from the product of 4 and a number results in the number added to 29

vitfil [10]

That would be:-

the solution:-

3x = 29 + 7

3x = 36

x = 12

Write the expression 44(4–7)(4) using a single exponent.

Ghella [55]

<h3>The given expression as single exponent is:</h3>

$4^4 \times 4^{-7} \times 4 = 4^{-2}$

<em><u>Solution:</u></em>

<em><u>Given expression is:</u></em>

$4^4 \times 4^{-7} \times 4$

In exponents,

When the base is same, exponents can be added

Which means,

$a^m \times a^n = a^{m+n}$

Therefore,

$4^4 \times 4^{-7} \times 4 = 4^{4-7+1}\\\\Simplify\\\\4^4 \times 4^{-7} \times 4 = 4^{-3+1} \\\\4^4 \times 4^{-7} \times 4 = 4^{-2}$

Thus the given expression as single exponent is:

$4^4 \times 4^{-7} \times 4 = 4^{-2}$

Rebecca trains for a marathon. She runs 6.8 miles in 34 minutes. Determine the

Solnce55 [7]

pretty sure it’s just 6.8 / 34. that’s 0.2, which is how much rebecca covers a minute

multiply 0.2 by the ten minutes you want to count, which is 2

therefore , rebecca covered 2 miles in 10 minutes :)
