Answer:
x = -1
Step-by-step explanation:
first, create a formula or expression:
7x - 2 = 10x + 1
now, move the 10x, subtract it on the other side
-3x - 2 = 1
add 2
-3x = 3
divide by -3
x = -1
you can substitute it in to check
Let h be the number of ham sandwiches
Let f be the number of fruit cups
Let c be the cost
C=4h+2f
C=(4*3)+(2*4)
C=12+8
C=$20

Answer:
FV= $17,321.20
Step-by-step explanation:
Giving the following information:
Annual deposit (A)= $3,000
Number of periods (n)= 5 years
Interest rate (i)= 7.2% = 0.072
<u>To calculate the future value (FV), we need to use the following formula:</u>
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
FV= {3,000*[(1.072^5) - 1]} / 0.072
FV= $17,321.20
Answer:
11. A) 6x = 13
Step-by-step explanation:
11. Subtract 10 from both sides to make it equal 6x=13
12. For #12... None of the answers seem right? If you distribute and subtract, it should be
-4x + 44 = 66 then
-4x = 22...
Sorry if this didn’t help much, I know that 11 is right though ;)
