Answer:
x = -1/7 or -0.14285 - in decimal form
Step-by-step explanation:
8x + 5 = -6x + 3
8x + 6x = 3 - 5 { change side }
14x = -2 { basic addition and subtraction }
x = -2/14 { changing sides }
x = -1/7 { simplified }
Answer:
the answer would be a
Step-by-step explanation:
In order to answer this question, we must break this mathematical expression up into a series of mathematical operations (exponent, multiplication,division, addition, and/or subtraction):
"4 times a number" - The word "times" implies that we have to multiply 4 by an unknown number. We can simply label this unknown number as x.
"cubed" - In order to "cube" a number, we must raise it to the third power, or have an exponent of 3. Our unknown number of x now becomes x3 because we raised it to the third power.
"decreased by 7" - The word "decreased" implies that we must subtract 7 from the product of 4 multiplied by x3
With all of the information we now have, we can form an algebraic expression for this problem.
"4 times a number cubed decreased by 3" now becomes:
4x3 - 7
Answer:
the awnser is 30
Step-by-step explanation:
mario and peach equal the same, so you would have to do 36÷3 and that equals 12, so then you look at mario divided by toad, and you would do 12÷2 to get 6, so toad would be 6, and that make bowser 0. so it would be 12+0+12+6=30
