Answer:
A.) 15.60=11.40+10x
Step-by-step explanation:
okay we know kathy spent 15.60 in total at the post office
so we know 15.60 will be after the equal sign.
she paid 11.40 only on the package
and rest of money was on stamps.
15.60-11.40= 4.20
so she used 4 dollars and 20 cents for stamps if she bought 10 we need to divied 4.20/10=0.42
0.42 cents for each stamps so we need a equation that will give us this answer.
Me i go thru each one and solve for x
lucky for me i just need to solve one
because equation A solves it correctly.
15.60=11.40+10x
subtract 11.40 on both sides
15.60-11.40
4.20=10x
now we divide 10 on each side
4.20/10=0.42
x=0.42
Hi there,
5x?=110 ?=22
how? 110/5=22
now 2x?=110
110/2=55 ?=55'
so we know now that people bought 22 packages with card and 55 w/th out cards!
so no we need to divide 695/both
695/5=139 packages with cards
695/2=347 packages without cards
SO
139 packages with card
347 packages without card
Answer:
The answer is A.

Answer:
- 38
Step-by-step explanation:
Here in this question, we have to simplify a certain numeric term to get a simple answer.
The expression is ( - 6 times + 3 ) + ( 5 times - 4 )
= - ( 6 times 3 ) + (5 times - 4)
= - ( 6 × 3 ) - ( 5 × 4 )
= - 18 - 20
= - 38 (Answer)
