Answer:
1lb 2 ounces
Step-by-step explanation:
Just multiply 3 by 5.9
Answer:
11
Step-by-step explanation:
First, write an equation to represent the situation.
34 = 2a + 12
This equation works because your combined age is half of 68, so 34. If your age is a, then yours sister's age is a + 12. if you add your age to your sister's, you get 2a + 12.
Now just solve for a.
34 = 2a + 12
First, subtract 12 from both sides.
22 = 2a
Then divide both sides by 2.
11 = a
So you are 11 years old. If you need to check your work, your age (11) plus your sister's age (11 + 12, which is 23) is 34, which is half of your grandfather's age.
Answer:
Step-by-step explanation:
Question 1:
First, write the equation out:
4(x+3)=7x-3
solve for x:
4x+12=7x-3
15=3x
x=5
Question 2:
Do the same on the second question:
30-x=3x-6
36=4x
x=9

this is easy just multiply the VALUE of the cards or divide using standard algorithm
Answer: 113.1 cm^2
Step-by-step explanation: The formula to find the area of a circle is 3.14r^2. R stands for radius which is 6 in this case so just plug that in for R. 3.14(6)^2=113.1
