Answer:
x= -10
Explanation:
When solving for x with 2 equations given, you’d add 3x+10 with 7x-30 like so: 3x+10=7x-30. you ALWAYS work your way from right to left till you’ve got nothing on your right but a number with no variable, so subtract 7x with 3x, giving you 4x, so now your equation would be: 4x+10=-30. Now that there is a single number to the right, you start to rotate, so subtract 10 from -30, giving you -40, so now your equation would be: 4x=-40. This is the last step, so all you have to do is divide 4x to itself and to -40. You DO NOT add the variable x to your answer, so it should be: x=-10 as your final answer.
Option B
The thickness of each washer is 0.083 inches
<em><u>Solution:</u></em>
Given that Bryce buys 9 bolts and he buys 9 washers to place onto the bolts
He puts the washers he bought in a stack that has a height of 0.747 inches
To find: thickness of each washer
From given information,
Number of washers bought = 9
Height of stack = 0.747 inches
Thus, thickness of each washer can be found by dividing height of stack by number of washers bought
Substituting the values we get,
Thus thickness of each washer is 0.083 inches
