Sherri saves nickels and dimes in a coin purse for her daughter. The total value of the coins in the purse is $0.95. The number

forsale [732]

I’m guessing that this is for systems of equations?
n - nickels
d - dimes

These are the equations you start off with.
n = 5d-2
0.95 = 0.10d+0.05n

Substitute the top equation for n into the variable n in the bottom equation.
0.95 = 0.10d+0.05(5d-2)

Solve for d.
0.95 = 0.10d+0.25d-0.10
1.05 = 0.35d
3 = d

Substitute d into the top equation and solve for n.
n = 5(3)-2
n = 15-3
n = 12

There are 3 dimes and 12 nickels in the coin purse! Hope this helped <3

Solve 7x + 2 < 9x - 4

Alexus [3.1K]

Answer:

$\boxed{\bold{x>3}}$

Step By Step Explanation:

Subtract 2 From Both Sides

$\bold{7x+2-2$

Simplify

$\bold{7x$

Subtract 9x From Both Sides

$\bold{7x-9x$

Simplify

$\bold{-2x$

Multiply Both Sides By -1 (Reverse Inequality)

$\bold{\left(-2x\right)\left(-1\right)>\left(-6\right)\left(-1\right)}$

Simplify

$\bold{2x>6}$

Divide Both Sides By 2

$\bold{\frac{2x}{2}>\frac{6}{2}}$

Simplify

$\bold{x>3}$
