Answer:
Sheila had $300 at first
Step-by-step explanation:
Given that:
Sheila spent:
for coat = $120
Let the original money be x so,
dress for = $(2/3(x - 120 ))
Now she left with = 1/5x
Now by adding all the amounts we get the original amount x:
x = 120 + (2/3(x - 120)) + 1/5x
By simplifying:
x = 120 + 2/3x - 240/3 + 1/5 x
adding like terms:
x = 120 - 80 + 2/3*5/5x + 1/5*3/3x
x = 40 + (10+3)x/15
x = 40 + 13x/15
x - 13x/15 = 40
Taking LCM
(15x - 13x)/15 = 40
2x/15 = 40
Multiply both sides by 15/2
x = 40*15/2
x = $300
so Sheila had $300 at first

30 is the value of the 3 in 6035
Answer:
Contrapositive. Switching the hypothesis and conclusion of a conditional statement and negating both. For example, the contrapositive of "If it is raining then the grass is wet" is "If the grass is not wet then it is not raining."
Step-by-step explanation:
Given the expression:
to solve for x, first we have to move the constant -8 to the right side of the equation. By doing this, the constant will change its sign when it's on the other side:
Now, we need to move the -3 to the right side. Since it is multiplying the variable x, we need to move it to the other side doing its opposite operation: the division:
notice that we have a division of a positive number by a negative number, then the result will be a negative number as well:
therefore x=-6
