Answer:
a=2
b=5
Step-by-step explanation:
5a=2b
a=2/5b
2(2/5b) -3b= -11
4/5b-3b =-11
-2.2b=-11
b=5
5a=2*5=10
a=2
Answer: 24
Explanation: You’ll have to multiply the numbers. 12x6 = 72. 12x-4 = -48.
72 + (-48)
You remove the parentheses because when there’s a “+” in the front of an expression in parentheses, the expression remains the same.
Therefore, it’s just 72-48. Subtract that and you’ll get 24. Hope this helps! (:
Answer:
95.45
Step-by-step explanation:
83% of 115 is 95.45
.83 × 115 = 95.45
if you wanted 83% of what is 115 then it would be 83% of 138.5542169 = 115
.83a = 115
115/.83 = a
115/.83 = 138.5542169
check:
.83 × 138.5542169 = 115
If 3 of the pennies are Canadian, then the other 12-3=9 pennies are not Canadian. Therefore, the desired probability is 9/12, which is equal to 3/4. B is the correct answer.
