Answer:
-9
Step-by-step explanation:
2(-x)² - 5 = 157
2x² - 5 = 157
add 5 to each side of the equation:
2x² = 162
divide both sides by 2:
x² = 81
√81 = 9 or -9
I think it’s B but I’m not for sure
Let's solve your equation step-by-step.
6.75+38x=1314
Step 1: Simplify both sides of the equation.
38x+6.75=534
Step 2: Subtract 6.75 from both sides.
38x+6.75−6.75=534−6.75
38x=132
Step 3: Multiply both sides by 8/3.
(83)*(38x)=(83)*(132)
x=523
Answer:
x=1713
The answer for this question would be choice A) 0.357 or the first option because 5/14 made into a decimal number would be 0.357143 and i got that answer by dividing 5 and 14, but u said round to nearest thousandth, so now we have the result we still have to round it and 0.357143 rounded to the nearest thousandth would be 0.357.
