$4z + 2 = 10z - 1$

Add sides 1

$4z + 2 + 1 = 10z - 1 + 1$

$4z + 3 = 10z$

Subtract sides 4z

$- 4z + 4z + 3 = - 4z + 10z$

$3 = 6z$

$6z = 3$

Divide sides by 6

$\frac{6z}{6} = \frac{3}{6} \\$

$z = \frac{1}{2} \\$

$3y = y + 3$

Subtract sides y

$- y + 3y = - y + y + 3$

$2y = 3$

Divide sides by 2

$\frac{2y}{2} = \frac{3}{2} \\$

$y = \frac{3}{2} \\$

Thus the correct answer is :

$a) \: y = \frac{3}{2} \: , \: z = \frac{1}{2} \\$

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 $1$ .

Goran rented a truck for one day. There was a base fee of $17.99 , and there was an additional charge of 75 cents for each mile

Vikki [24]

Cost of the total miles travelled
= $191.24 - $17.99
= $173.25

Miles travelled
= $173.25 ÷ 0.75
= 129.9375 miles
≈ 130 miles (3s.f)
