Answer:
x = 13.5 weeks
Step-by-step explanation:
Since he wants to save $189 in total, that will be on one side of the equation by itself. You have to set this up in a y = mx + b equation. The y will be the 189. Since the word "each" goes with the number 14, that will be your m value. There is no value for b.
189 = 14x is your equation. The only step after setting up the equation is to divide 189 by 14. This gives you 13.5. Dennis will have to save up for 13.5 weeks.
Answer: Basically you do the opposite of each sign to isolate the variable on one side.
Step-by-step explanation:
x + 9 = 17
-9 from each side
x = 8
x - 6 = 25
+ 6 to each side
x = 31
8x = 48
Divide each side by 8
x = 6
x/4 = 7
Multiply each side by 4
x = 28
Answer:
AB = 2.18 units
Step-by-step explanation:
We are given that two lines are cutting by a transversal line.
We can see that angle <1 and angle 78 degree are Consecutive Interior Angles.
Note: When two parallel lines cut by a transversal line, the each pair of angles inside the parallel lines on the same side of the transversal are called Consecutive Interior Angles.
Also please note that two Consecutive Interior Angles are supplementary.
In simple words, the sum of two Consecutive Interior Angles is 180 degree.
So, we can apply supplementary angles property of Consecutive Interior Angles to find the angle <1 and given angle 78 degrees in the given diagram.
Therefore, <1 + 78 = 180°.
Subtracting 78 from both sides, we get
<1=102°.
Therefore, <1=102°.
Y=3/2x+4
3/2(2)+4
3/2(2)= 3
3+4=7
g(2)=7
