Substitute the known value of x into y=4x+20. Then solve for y entering the equation in simplest form

scoray [572]

Answer:

$y=24,$ when $x=1$ .

Step-by-step explanation:

Given: $y=4x+20$

To find: Value of $y$ , substituting the known value of $x$

We have,

$y=4x+20 ...(i)$

Putting $x=1$ in equation $(i)$ , we get

$y=4(1)+20$

$\implies y=4+20$

$\implies y=24$

Hence, the value of $y$ is $24$ , when the value of $x$ is $1$ .

Brad wants to buy flowers for his friend with $33. The daisies are $1 each and the roses are $3 each. He buys 3 more daisies tha

Darina [25.2K]

Let x=the amount of roses that Brad buys. (x+3)=the number of daisies that Brad buys.

x+(x+3)=33

Simplify this problem to find the amount of roses:

2x+3=33

2x=30

x=15

So, Brad buys 15 roses and 18 daisies.

Since roses cost $3, 15*3=45.

The roses cost $45.

Hope this helps! :)
