When you have 2 problems of the same such as 6+(3*8)-4 then you do it backwards instead of adding first you are going to subtract first then add.

Order of operations tells you what to do in which order when you have a bunch of different operators. the abbreviation is PEMDAS, which stands for the order:

1. parentheses
2. exponents
3. multiplication
4. division
5. addition
6. subtraction

Plz help! I don’t understand this
kiruha [24]

Answer:

Option B

Step-by-step explanation:

-1/2x≥4

1) Multiply both sides of the inequality by the reciprocal of -1/2: (-2)

x≤-8

Graph x≤-8 as a line. Remember that lesser negative values go to the left!

ALSO don't forget when you multiply both sides of an inequality by a negative number the inequality sign flips.

Rita runs 6 miles in 44 minutes. At the same rate, how many minutes would she take to run 9 miles?
kherson [118]

You run 0.5 miles every 3 minutes => 1 mile every 6 minutes. Your friend runs 2 miles every 14 minutes => 1 mile every 7 minutes. You run a whole number of miles every number of minutes that is a multiple of 6. Your freind runs a whole number of miles every number of minutes that is a multiple of 7 Then the least possible number of miles that you both run to end at the same time is the least common factor of 7 and 6 minutes. This is 7 * 6 = 42 minutes. You will have run 42 min / (6 miles/min) = 7 miles, and your friend will have run 42 min / (7 miles/min) = 6 miles
