Answer:

d=9

Step-by-step explanation:

First we can do same to both side by adding 2 to both sides:

1=1/3d-2

+2 +2

--------------

3 = 1/3d

Then to get the d on its own, we multiply each side by 3

3=1/3d

*3 *3

---------

9=d

Our final answer is 9

Answer:

d = 9

Step-by-step explanation:

Given

1 = $\frac{1}{3}$ d - 2 ( multiply through by 3 to clear the fraction )

3 = d - 6 ( add 6 to both sides )

9 = d

Step-by-step explanation:

x = 51.5

I'm am not sure about it since in the case it is not given that how much miles he walk in total so.

I just added the no. of miles he walk in part A and B so I got x = 51.5

hope this answer helps you dear...take care and stay safe!

Write the sum of the numbers as the product of their GCF and another sum 64+28 PLEASE ANSWER QUICKLY

zepelin [54]

64 and 28 have a GCF of 4, since 64 = 4 x 16, 28 = 4 x 7, and 7 and 16 have no factors other than 1 in common. Knowing that, we can rewrite 64 + 28 as

4 x 16 + 4 x 7

and then use the distributive property to rewrite it again as

4 x (16 + 7)

Simplify the expression (2b/3)^4 A. 16b^4/81 B. 16b^4/3 C. 8b^4/12 D. 6b^4

Ilya [14]

Answer:

A.16b^4/81

step-by-step explanation:

(2b/3)^4

= (2b)^4/3^4

= (2^4×b^4)/3^4

=16b^4/81

(as 16 and 81 cant simplify each other)

If the value of x increases by 4 ,how does the value of m(x-5) change

seraphim [82]

I'm going to assume that you're discussing the linear function y = mx + b. If that's not it, please provide more information on the function you're studying.

y = mx + b has a graph that is the straight line through (0,b) with slope m.

y = m(x-5) + b has a graph which is parallel to the previous graph, but intersects the x-axis at a different point.

Examples: start with y = mx + b
Suppose we have y = 3x + 2 to work with
The graph intersects the y-axis at (0,2). It intersects the x-axis where y=0=3x+2, or at x = -2/3 => (-2/3, 0)

Now modify y = 3x + 2 by replacing "x" with "x-5." the graph of this "new" function f(x) = 3(x-5) + 2 is parallel to the original graph, but lies 5 units to the right of the original graph. Both lines have slope 3.

In this case, if x increases by 4 (as your problem states), y will increase by 3(4), or 12, units.

If we go back to y = m(x-5), we see that the graph of this function intersects the x-axis at x=5, and this graph has the (unknown) slope m.

If x increases by 4, y increases by (m)(4), or 4m.
