answer:
-4
Step-by-step explanation:
-3x+8= 20
-8 -8
-3x = 12
÷-3. = ÷-3
x = -4
To find this answer, you would need to use the equation for area of a circle, or in this case, a=3.14x289, since 3.14 is pi and 289 is your radius squared. giving you a final answer of 907.46 feet squared.
Answer:
Ari has 14 pennies.
Step-by-step explanation:
Number Value Total value
Pennies p $0.01 0.01p
Nickels (22 - p) $0.05 $(22 - p)0.05
Total 22 - $0.54
Since Ari has total value of the coins = $0.54
0.01p + (22 - p)0.05 = 0.54
0.01p - 0.05p + 1.1 = 0.54
-0.04p = -0.56
p = 
p = 14
Therefore, total number of pennies Ari has = 14
A/b+c/b=(a+c)/b
make bottom number same
multiply by 1 or x/x where x=x
easy way is
if you had
a/b+c/d
multiply a/b by d/d and multiply c/d by b/b
2/5 times 4/4=8/20
2/4 times 5/5=10/20
add
8/20+10/20=(8+10)/20)=18/20=9/10
I should have simplified 2/4 to 1/2 first
