Answer:
Harry is 40 Sean is 10
Step-by-step explanation:
4L + 20 = 2(L+20), or 4L + 20 = 2L + 40, 4L - 2L = 40 - 20, 2L = 20 ---> L = 10.
Answer:
-13 5/7 divided by -56/91 is 22 2/7
Step-by-step explanation:
By checking, (don't do it my way)
#1. 13 5/7 is 96/7 as an improper fraction.
#2 Then, make it negative.
#3 -56/91 is simplified as -8/13
#4 Divide. --> -96/7 :(-8/13)=-96/7*-13/8= -96/*(-13)/7*8=1248/56=156/7
=22 2/7
We have been given a system of equations. and . We are asked to find the solution of our given system of equations.
The solution of our given system of equations will be the point, where both lines will intersect.
To find intersection point, we will equate both equations as:
Now we will substitute in equation and solve for y.
Therefore, the point is the solution of our given system of equations.
We can verify our answer by graphing both equations.
Answer:
A) 300.001 = 300
6.75 = 6
B) + 36.5 = +37
+54.6 = +55
C) -45.6 = - 46
-25.5 = -26
D) 2888 = 2890 ( nearest ten)
2888 = 2900 ( nearest hundreds)
2888 = 3000 ( nearest thousands)
Step-by-step explanation:
Round toward 0
Rounding towards zero is a simple rounding mode. All digits beyond the number required are dropped. Rounding towards zero results in a number whose magnitude is always less than or equal to the more precise original value.
Examples are:
300.001 = 300
6.75 = 6
Round toward positive infinity
This means the result of the rounding is never smaller than the argument. Examples are:
+ 36.5 = +37
+54.6 = +55
Round toward negative means the result of the rounding is never larger than the argument.
Examples are
-45.6 = - 46
-25.5 = -26
Round to nearest means the result of rounding is sometimes larger, sometimes smaller than (and sometimes equal to) the argument
It can be to the nearest ten, hundreds, thousands or millions etc
2888 = 2890 ( nearest ten)
2888 = 2900 ( nearest hundreds)
2888 = 3000 ( nearest thousands)
