Answer:
we have that√(87*x)we know that87 is equal to------> 3*29In order for the square root to go further, the number for "x" has to have a factor of 3 or 29the number 21-------> 3*7so√(87*x)------> √(3*29*3*7)------> √(3²*29*7)----> 3√203the answer isx=21
Step-by-step explanation:
1 pound= 16 ounces
3/4 pound= 12 ounces
multiply 8X16=128 ounces plus
12 ounces=
140 ounces total

He worked 3 8-hour days.
Let x be the number of 8 hour days. Then 10-x is the number of 6 hour days.
8x + 6(10-x) = 66
Using the distributive property,
8x + 6*10 - 6*x = 66
8x + 60 - 6x = 66
Combining like terms:
2x + 60 = 66
Subtract 60 from both sides:
2x + 60 - 60 = 66 - 60
2x = 6
Divide both sides by 2:
2x/2 = 6/2
x = 3
Answer:
14.
Step-by-step explanation:
[(12−5)⋅12]÷6 First calculate the numbers in the inner brackets:
= (7 * 12) / 6 Now deal with the remaining brackets:
= 84 / 6
= 14.
