Answer:
the answer is 80
Step-by-step explanation:
QR=ST: 7x+3=5x+25
2x=22
x=11
7(11)+3=80 5(11)+25=80
75/15 = 5
5 ounces per ball
15/5 = 3
3 balls are 15 ounces
Step 1) simplify the constants, so basically you are doing the 3-4 part and turning the equation in -8x-1>-1
Step 2) isolate the variable, first you need to add 1 to both sides to cancel it off then the equation is -8x>0. Next you divide both sides by -8, don't forget that when you multiply or divide by a negative you need to flip the sign which makes the equation x<0 because when you divide 0 by any number it is still 0
Hope this helped!
Answer: x<0
Answer:
Step-by-step explanation:
Answer:
125
Step-by-step explanation:
x(t) = x0 × (1 + r) t
where:
x(t) = the amount of some quantity at time t
x0 = initial amount at time t = 22
r = the growth rate
t = time
