Answer:
x = 2, and y = -1. Point form: (2, -1)
Step-by-step explanation:
You solve the system of equations, by solving for one variable, and then subsitiute that variable into the other equation.
A 16 karat gold means that there are 16 parts of gold in
24 parts of the gold chain. Therefore the weight of the pure gold is:
pure gold = (16 / 24) * 2.6 ounces
<span>pure gold = 1.73 ounces</span>
Answer: g = 42
Step-by-step explanation:
g/3 + 11 = 25
First, subtract 11 to both sides
g/3 = 14
Then, multiply 3 to both sides to get rid of the fraction
g=42
Answer:
PQ = 3.2
Step-by-step explanation:
PQ = PR - QR
PQ = 4.8 - 1.6
PQ = 3.2
Answer:
The right answer is: 14,256 cubic inches
Step-by-step explanation:
First of all, let's identify the dimensions of the tank and convert them to inches
Knowing that 1 Feet = 12 inches
So, the dimensions of the tank, expresed in inches will be:
Height (H): 2 ft. x 12 = 24 inches
Width (W): 1.50 ft. x 12 = 18 inches
Lenght (L): 3 ft. x 12 = 36 inches
Before calculating the volume of water inside the thank, We must consider that <em>there are two inches of empty space at the top.</em>
So , We must substract 2 inches to the height to calculate the volume.
Then, the height used for calculating the volume will be:
H'= 24 inches - 2 inches = 22 inches
Then,
Volume (V)= W x L x H'
V= (18 inches) x (36 inches) x (22 inches)
V= 14,256 cubic inches
