Answer:
Solve for A by simplifying both sides of the equation, then isolating the variable.
A
=
45
−
B
4
Step-by-step explanation:
To make things easier, this solid can be divided in 3 parts:
- the first one is 2in long, 5in wide and 8in tall
- the second one is 2in long, 8in wide and 3in tall
- the third one is just like the first one, so 2in long, 5in wide and 8in tall
In order to find the volume of the solids, we need to multiply their dimensions:
1st: 2.5.8 = 80
2nd: 2.8.3 = 48
3rd: 2.5.8 = 80
The volume of the big solid is equal to (80 + 48 + 80)
V = 208
Answer:
Step-by-step explanation:
Let x = $ invested in 8% account
y= $ invested in 10.5% account
x + y= 12000
0.08x + 0.105y = 1145
$4600 invested in the 8% account
and $7400 invested in the 10.5%
account
<span>A stack of 100 pennies, one on top of the other, is 15.5 centimeters tall. </span>
<span>a penny is 1.55 mm thick, so a stack of </span>
<span>100 pennies would be 155 mm thick or 15.5 centimeters. </span>
<span>This means that a stack of 100 pennies is 6.1 inches in height.</span>
Answer:
y=3
Step-by-step explanation:
y + 3 = –y + 9
Add y to each side
y+y + 3 = –y+y + 9
2y+3 = 9
Subtract 3 from each side
2y+3-3 = 9-3
2y = 6
Divide by 2
2y/2 = 6/3
y =3
