5. Solve each equation by systematic trial.
Basile [38]

Answer:

a) x = 260

b) g = 218

c) z = 30

d) h = 5

Step-by-step explanation:

a) x-68=192

Predict a number; let's say x = 225

225-68=192\\157=192

Too low; try with a higher number; let's say x = 270

270-68=192\\202=192

Too high, we're closer.

x = 260

260-68=192\\192=192

--------------------------------------------------------------------------------------

b) g+33=251

let's say g = 230

230+33=251\\263=251

Too high. Try g = 221

221+33=251\\254=251

We're almost there. Let's try with g = 218

218+33=251\\251=251

----------------------------------------------------------------------------------------

c) 3z-16=74

Let's try with z = 15

3(15)-16=74\\45-16=74\\29=74

Too low; try a higher number. z = 30

3(30)-16=74\\90-16=74\\74=74

--------------------------------------------------------------------------------------------

d) 15h+9=84

Let's try with h = 6

15(6)+9=84\\90+9=84\\99=84

Too high; let's try with h = 5

15(5)+9=84\\75+9=84\\84=84

The table below shows the number of skateboards sold at a skate shop each week for five weeks.
hammer [34]

Answer:

s = 22w

Step-by-step explanation:

We need to try this equation for all of the numbers in the table.

s = 22w

22 = 22 * 1

s = 22w

44 = 22 * 2

s = 22w

66 = 22 * 3

s = 22w

88 = 22 * 4

s = 22w

110 = 22 * 5

I need help n pls explain ​
WARRIOR [948]

Answer:

The correct option is C). When it was purchased, the coin was worth $6

Step-by-step explanation:

Given function is f(t)=6\times2^{t}

Where t is number of years and f(t) is function showing the value of a rare coin.

A figure of f(t) shows that the graph has time t on the x-axis and f(t) on the y-axis.

Also y-intercept at (0,6)

hence, when time t was zero, the value of a rare coin is 6$

f(t)=6\times2^{t}

f(0)=6\times2^{0}

<em>f(0)=6</em>

Thus,

The correct option is C). When it was purchased, the coin was worth $6
