Solve the following using the elimination or substitution method. Show all work.

ki77a [65]

Jim has 28 nickels and 37 dimes in his pocket. which is determined by the substitution method.

<h3>What is the equation?</h3>

The term "equation" refers to mathematical statements that have at least two terms with variables or integers that are equal.

Let the number of nickels would be n

Let the number of dimes would be d

As per the given question,

d + n = 65 ....(i)

0.10d + 0.05n = 5.10 ....(ii)

From equation (i),

d + n = 65

d + n - n = 65 - n

d = 65 - n

Substitute in for the equation(ii): d = 65 - n

0.10(65 - n) + 0.05n = 5.10

6.5 - 0.10n + 0.05n = 5.10

6.5 - 0.05n = 5.10

6.5 - 0.05n - 6.5 = 5.10 - 6.5

- 0.05n = -1.4

n = 28

This means there are 28 nickels

Substitute the value of n = 28 in the equation (i),

d + n = 65

d + 28 = 65

d = 37

So there are 37 dimes

Thus, Jim has 28 nickels and 37 dimes in his pocket.

Study the example on the right to help you complete the problem below. please help!:(

Inga [223]

Answer : The equation for 'h' is $h=\frac{2A}{b}$

Step-by-step explanation :

The given equation is:

$A=\frac{1}{2}bh$

Now we have to determine the equation for 'h'.

$A=\frac{1}{2}bh$

Multiplying the equation by 2.

$2\times A=2\times \frac{1}{2}\times bh$

on simplifying, we get:

$2\times A=bh$

Dividing the equation by 'b'.

$\frac{2\times A}{b}=\frac{bh}{b}$

$\frac{2\times A}{b}=h$

or,

$h=\frac{2A}{b}$

Therefore, the equation for 'h' is $h=\frac{2A}{b}$
