Answer:
x = -2
Step-by-step explanation:
5x + 2(x - 4) = 5x + x - 10
→ Expand the brackets
5x + 2x - 8 = 5x + x - 10
→ Collect the x terms
7x - 8 = 6x - 10
→ Minus 6x from both sides
x - 8 = -10
→ Add -8 to both sides
x = -2
Answer:
FV= $1,335.57
Step-by-step explanation:
Giving the following information:
Initial Investment (PV)= $1,200
Interest rate= 1.8% compounded annually
Number of periods= 6
<u>To calculate the future value, we need to use the following formula:</u>
FV= PV*(1+i)^n
FV= 1,200*(1.018^6)
FV= $1,335.57
Answer:
s = 17
Step-by-step explanation:
17 = 4(s - 14) - (-5)
distribute the 4
17 = 4s - 56 - (-5)
combine like terms
17 = 4s - 56 + 5
17 = 4s - 51
add 51 to both sides
68 = 4s
divide by 4
68/4 = 17
s = 17
Answer:
The number of brownies in each batch is less than 8.
Step-by-step explanation:
Baked batches of brownies = 2.5
Number of burned brownies = 5
Number of brownies left is less than 15
So, the total number of brownies is less than 15 + 5 = 20
Number of brownies in each batch is
n < 20/2.5
n < 8
So, the number of brownies in each batch is less than 8.
