Answer:
im pretty sure it'd be 76 weeks!
Step-by-step explanation:
one water tank holds 1216 and loses 5 gallons/week
another water tank holds 1520 gallons and loses 9 gallons/week
youd make an equation:
1216-5x=1520-9x
(each side being the amount of water the tank can hold minus the amount it loses per week [x])
heres how you execute the equation:
1216-5x=1520-9x
-5x=1520-1216-9x
-5x=304-9x
-5x+9x=304
4x=304
x=304/4
76
after you do the equation, you get x=76, meaning 76 weeks! :-)

Part 1) Option D
Part 2) Option C
Step-by-step explanation:
we know that
In a Rhombus
Opposite angles are congruent, and consecutive angles are supplementary. All sides are congruent by definition. The diagonals bisect the angles
Part 1) What is the measure of angle ?
-----> remember that the diagonals bisect the angles
Part 2) What is the measure of angle ?
Remember that
In a rhombus consecutive angles are supplementary
so
The measure of angle is equal to the measure of angle T divided by

Answer:
7
Step-by-step explanation:
Simply plug in 5 for <em>x</em>

Answer:
$9.70
Step-by-step explanation:
Use PEMDAS:
Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
Problem:
C(x) = 0.06x + 8.50
Substitute x for 20:
C(20) = 0.06(20) + 8.50
Multiply 0.06 and 20:
C(20) = 1.2 + 8.50
Add 1.2 and 8.50:
C(20) = $9.70
The total cost for an order of 20 copies is $9.70
