4x4 = 16
Answer:
136% = 1.36
Step-by-step explanation:
(950-700)/700
=0.3571 (0.36)
Then you have to plus one
0.36+1
=136% or 1.36
So you would add 12 to the other side of the equation, and 9+12=21, so x=21.
The point estimate is the mid-point of the interval:
The margin of error is the difference between the endpoints of the interval and the mid-point.
Answer:
x=45/6
Step-by-step explanation:
2+7y=8. 7y=8-2. <u>7</u><u>y</u><u>=</u><u>6</u>
7=7. y=6\7
insert the value of y in the second equation. 5x-7y=16
5x-7(6/7)=16
5x-49\6=16
collect the liketerms together
5x=16+49/6
5x=145/6(divide both sides by 5)
x=29/6
x=45/6
<em><u>f</u></em><em><u>u</u></em><em><u>r</u></em><em><u>t</u></em><em><u>h</u></em><em><u>e</u></em><em><u>r</u></em><em><u>.</u></em>
<em><u> </u></em>confirm if the 2 in the second equation has an X coz the questions are normally set with both equations having both values x and y
