Answer:
Step-by-step explanation:
Think: 2/5 its body weight in 1/2 hour immediately becomes 4/5 its body weight in 1 hour. There's a proportional relationship here.
The class needs to sell at least 20 tickets
Let x be the number of tickets that need to be sold in order to add up to $1000
Using the equation $700+$15x>=$1000
Subtract 700 from both sides and then divide each side by 15 to get 20.
a x=12
the sum of angles in a triangle is 180
53+39+4+7x=180
96+7x=180
7x=86
x=84/7
x=12
b. sum of angles in a triangle is 180
5x+(6x-5)+75=180
5x+6x-5+75=180
11x+70=180
11x=180-70
11x=110
x=110/11
x=10
that's how to solve it
Answer:
7x - 12
Step-by-step explanation:
'12 less' means thats u have to subtract 12 from the next number
'7 times a number' means 7 multiplied by a variable like x, y, or z
you put those two together and get 7x - 12
