Answer:
<u>x=3</u>
Step-by-step explanation:
Addition property of equality is adding the same number to both sides of an equation does not change the equation.
a+c=b+c
3x-7=2
add 7 both sides of an equation.
3x-7+7=2+7
simplify.
3x=9
divide by 3 both sides of an equation.
3x/3=9/3
simplify.
9/3=3
3*3=9
9/3=3
<u>x=3 and 3=x</u>
Hope this helps!
Thanks!
7: $200<3x-y(28) where x represents each kids money out of it and y represents the parents pay.
8: 7.00>(is greater then or equal to) 0.75X + 1.29Y where X is the amount of bagels and Y is the amount of cream cheese containers.
9: $25 + $75>4X where X is the shirts
10: 720-120>(greater then or equal to) 32X where X is the number of people in each row
11: 2400= 2100+ X(1/20) where X is the value of all things sold.
12: 2000<(X7)-668 where X is the amount of cans in one day.
13: 100> 7X - 10Y where X equals the amount of months and Y equals the amount of CD's
14: $80 - $22> (greater than or equal to) 17X where x equals the amount of shirts.
first off sorry it took so long to answer, these long word questions are time consuming and i havent done them in a while so i had to refresh my memory, secondly the equations all end where i say the word "where", thirdly i am absolutely sure of all these answers except for the first one, the first one i am pretty sure i still got it but not 100%.
hope this helps.
Answer:
14
Step-by-step explanation:
Its like a clock, except directly away from the six is not twelve, it's 13. That means the clock would have to have added two numbers for there to be a whole number facing the six.
so since Mrs Jackson used 2/15 of 7/8, the amount she used is simply their product.
