Answer:
g(q) = 5/8q
Step-by-step explanation:
-7q + 12r = 3q - 4r
Add 4r to each side
-7q + 12r+4r = 3q - 4r+4r
-7q +16r = 3q
Add 7q to each side
-7q+7q +16r = 3q+7q
16r = 10q
Divide each side by 16
16r/16 = 10q/16
r = 5q/8
g(q) = 5/8q
Answer:
Each bracelet has 12 small charms and 5 large charms
Each order also gets<em> </em>5 blank spacer charms to use to separate charms or fill in the bracelet.
(a) 17x + 5 = y
17 charms are needed for each bracelet plus 5 blank spacer charms that come with each order.
(b) the order she is filling needs 158 charms. How many bracelets were purchased in this order?
17x + 5 = 158
Let's solve your equation
17x+5=158
Subtract 5 from both sides.
17x+5−5=158−5
17x=153
Divide both sides by 17.
17x / 17 = 153 / 17
x=9
9 bracelets were purchased in this order.
(c) Toby says they don’t have enough charms to fill an order that needs 264 charms. Sarah says it’s not possible for an order to need 264 charms.
17x + 5 = y
17x + 5 = 264
Subtract 5 from both sides.
17x + 5 -5 = 264-5
17x = 259
Divide both sides by 17.
17x / 17 = 259 / 17
x = 15.235
Sarah is wrong because 264 charms can make about 15 bracelets.

Answer:
remember to round numbers to 1 significant figure
Step-by-step explanation:
usually in an exam when you're asked to estimate the answer to a calculation, usually you round each number to 1 sf and then work on from there.
The formular which can be used to obtain the monthly charges as a function of the number of cheques written is 9.75 + 0.15x
Charges on account :
- Charge per check written = $0.15
- Monthly services charge = $9.75
The total amount charged monthly, F as a function of the number of cheques written, x can be expressed thus :
Monthly service charge + (charge per check × number of cheques written)
F(x) = 9.75 + 0.15x
Therefore, the charge function which can be used to calculate the total monthly charge on his account ls F(x) = 9.75 + 0.15x
