Answer:
$70
Step-by-step explanation:
If the account start with $95, and you deposited $15:
95+15 = $110
After that, you took 65:
110 -65 = $45
After you deposited $40:
45 + 40 = $85
And for last you took more 15:
85 -15 = $70
The number of hours Jeremiah ironed = 10 hours
The number of hours Tristan ironed = 7 hours
<u>Step-by-step explanation</u>:
- Jeremiah can iron = 35 shirts per hour
- Tristan can iron = 20 shirts per hour
- Total work done by both = 490 shirts
Let 'x' be the number of hours Jeremiah ironed.
Let 'y' be the number of hours Tristan ironed.
x+y = 17 ------(1)
35x + 20y = 490 -------(2)
Multiply (1) by 20 and subtract (2) from (1),
20x + 20y = 340
-(<u>35x + 20y = 490</u>)
<u>-15x = -150 </u>
x = 150/15
x = 10
Substitute x=10 in (1)
10+y = 17
y = 7
& 
so , 
.
<u>Step-by-step explanation:</u>
Here we have , ab= 8 & a^2+b^2=16 i.e. and .
We need to find value of (a+b)^2 i.e. 
:
It's and identity and we know that 
⇒
⇒ 
⇒ 
⇒ 
⇒
∴ & so , .
Answer:
7x+y= -2
