94. 7 pounds of grapes costs 10.43 dollars. Now, solve for the costs of 3 pounds of grapes.
There are different ways to solve this kind of situation. For my end, I will be showing the solution that I think is easier.
=> 7 pounds = 10.43 dollars.
Find the unit rate first
=> 10.43 dollars / 7 = 1.49 dollars per pounds.
Now, solve for the cost of 3 pounds
=> 1.49 * 3 = 4.47 dollars is the costs of 3 pounds of grapes.
The answer is 3 because the order of operations tells you to start off with parenthesis first, which would (I assume would anyways) be 15. Then you would do 45÷15, which is 3.
Answer:
3/8
Step-by-step explanation:
With unlike denominators find the Least Common Denominator (LCD)
LCD = 8
Multiplying numerators and denominators to get the LCD in all fraction denominators
=3/4 times 2/2−3/8
Then rewriting the equation with the equivalent fractions
=6/8−3/8
With like denominators we can operate on just the numerators
=6−3/8
=3/8
Alternate interior angles on parallel lines via the parallel postulate gives you the angle supplementary to x = 120°, so x = 60°. alternate interior angles on 70° via the parallel postulate gives you y = 70°
