Answer:

See below.

Step-by-step explanation:

Let d = number of dimes. Let q = number of quarters.

d + q = 35

A dime is worth 10 cents, or $0.1; d dimes are worth 0.1d.

A quarter is worth 25 cents, or $0.25; q quarters are worth 0.25q.

0.1d + 0.25q = 4.9

The system of equation is

d + q = 35

0.1d + 0.25q = 4.9

In the equation 3/4y+1/2=3 1/4, the fractional coefficient is what

AURORKA [14]

Answer:

$\frac{3}{4}$

Step-by-step explanation:

Given equation: $\frac{3}{4}y + \frac{1}{2} = 3 \frac{1}{4}$

In the given equation, $\frac{3}{4}$ is a coefficient and y is the variable.

coefficient is a constant number or quantity multiplied to a variable in an algebric expression. Like in the above equation $\frac{3}{4}$ is a coefficient and y is the variable. We use term variable for y as its value may vary or change. If variable does not have any coefficient in any expression then in that case, we consider 1 as coefficient, for example: $x+4$ , here variable have 1 as coefficient.
