You'll have to solve simultaneously

let nickel be x, dime be y

x + y = 35 ... ( 1 )

5x + 10 y = 250
5 ( x + 2y ) = 250
x + 2y = 50 ... ( 2 )

in ( 1 )
x = 35 - y ( 3 )

sub ( 3 ) into ( 2 )
( 35 - y ) + 2y = 50
y = 15

sub y into ( 1 )
x + y = 35
x + 15 = 35
x = 20

therefore, Sandy has 20 nickels and 15 dimes

Suppose the function of h is defined, for all real numbers as follows: (f) x = -3 if x is <) 3 if x is =0 -2 if x is > 0

V125BC [204]

Answer:

See explanation

Step-by-step explanation:

The question is not properly presented; I will answer this with the following similar question.

$h(x) = -\frac{1}{3}x^2 + 4$ --- $x \ne 2$

$h(x) = -4$ --- $x= 2$

Required

$h(-5)\ \&\ h(2)$

<u>Calculating h(-5)</u>

This implies that: x = -5

$-5 \ne 2$

So, we make use of:

$h(x) = -\frac{1}{3}x^2 + 4$

Substitute -5 for x

$h(-5) = -\frac{1}{3} * (-5)^2 + 4$

$h(-5) = -\frac{1}{3} * 25 + 4$

$h(-5) = -\frac{25}{3} + 4$

Take LCM

$h(-5) = \frac{-25+12}{3}$

$h(-5) = -\frac{13}{3}$

<u>Calculating h(2)</u>

This implies that: x = 2

$2 = 2$

So, we make use of:

$h(x) = -4$

Substitute 2 for x

$h(2) = -4$

In the equation below, a and b are constants. If a = b, what is the value of x in terms of y ? 2xa=8yb Select one:

Bas_tet [7]

Answer: $x=4y$

Step-by-step explanation:

The equation is $2xa=8yb$ .

To find the value of the variable "x" in terms of "y", you need to apply the Division property of equality and divide both sides of the equation by "2a". Then:

$\frac{2ax}{2a}=\frac{8yb}{2a}$

$x=\frac{8yb}{2a}$

You know that the costants "a" and "b" are equal ( $a=b$ ), then:

$\frac{b}{a}=1$

Knowingt this, you can simplify.

Therefore, you get that the value of "x" in terms of "y" is:

$x=4y$
