The solution of the information given will be as follows:
5√(x+7)=10
dividing both sides by 5 we get:
√(x+7)=2
squaring both sides we get:
(x+7)=2²
x+7=4
solving for x we get
x=4-7
x=-3
thus the answer is x=-3
this is an extraneous solution.<span />
No cause you got three terms
Total combinations are found by multiplying the quantities of each part by each other.
3 kinds of meat x 2 types of bread x 3 types of drinks
A) total combinations = 3 x 2 x 3 = 18
B) there are 18 different combinations, ham in rye with tea is 1 combination.
The probability would be 1/18
Step 1 he had to multiply the $22.75 times 3 weeks it should have been
($22.75 x 3) + $32.75 - $14.25
$68.25 + 32.75 - $14.25
$86.75
I dont know what the answer is to this question
