Answer:

I believe the one that is selected is correct.

Step-by-step explanation:

1/5k - 2/3j and -2/3j + 1/5k

If you switch the subtraction to addition, 2/3 becomes negative, while 1/5 stays the same.

PLS HELPS ASAP 2/18/20
wel

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.

Step-by-step explanation:

I hope this helps

Have a nice day!!

Nick and June win some money and share it in the ratio 4:5. Nick gets £40. How much did June get?
sineoko [7]

Answer:

June gets \£50

Step-by-step explanation:

Let

x ----> amount of money Nick gets

y ----> amount of money June gets

we know that

\frac{x}{y}=\frac{4}{5} -----> equation A

x=40 ----> equation B

solve the system by substitution

substitute equation B in equation A

\frac{40}{y}=\frac{4}{5}

solve for y

Multiply in cross

(40)(5)=y(4)\\y=200/4

y=\£50

HELP I GIVE 15 POINTS
ExtremeBDS [4]

Answer:

Alright well first off you start by converting everything to fractions, but decimals work better for me. So it would be 40.5 and 1.25, 40.5 being miles and the other gas. Divide 40.5 by 1.25, giving you 32.4

<u><em>His car get 32.4 miles per gallon</em></u>
