Answer:
x = 7 / 2
Step-by-step explanation:
5(2x - 9) + 3 = -7 ---------- subtract 3 from both sides
5(2x - 9) + 3 - 3 = -7 - 3
5(2x - 9) = -10 ------ divide both side by 5
2x - 9 = -2 ---------- add 9 to both sides
2x - 9 + 9 = -2 + 9
2x = 7
x = 7 / 2
Answer:
7.92%
Step-by-step explanation:
Given the following
Weight of package at home = 20.2 ounces.
Weight of the package at the office = 18.6ounces
Decrement = 20.2 - 18.6
percentage error = decrement/wt at home * 100
percentage error = 1.6/20.2* 100
percentage error = 160/20.2
percentage error = 7.92
HEnce the percent error in the weight of the package is 7.92%
Answer:
4.5 pounds
Step-by-step explanation:
Convert them both to improper equations.
2 3/4 = 11/4
1 3/4 = 7/4
Then add.
11/4 + 7/4 = 18/4
Then simplify.
18/4 = 4 2/4 = 4.5
It’s b. Because the number with out the x is the y-interact which is -2 then to find the other number I look at the graph and find another point and then count the rise/run which is rising 2 running 3 and it’s also positive that’s why it’s b.
