Answer:
x = 5.5
Step-by-step explanation:
Solve for x by simplifying both sides of the equation, then isolating the variable.



-7 -7

Divide both sides by -1.

Answer:
∠DEF = 250°
Step-by-step explanation:
1. This shape is a hexagon (6 sides), so the interior angles should all add to 720°. Also worth noting: the problem says the <em>obtuse</em> angle DEF; this means it's the angle INSIDE the shape, not outside.
2. Add all the known angles, then subtract from the total degrees:
50 + 96 + 144 + 42 = 332
720 - 332 = 338
3. Because BC is parallel to ED, we can subtract 180 - 42 for the value of ∠EDC, which is 138°.
4. Add all the known values and subtract from 720 for the value of ∠DEF:
50 + 96 + 144 + 42 + 138 = 470
720 - 470 = 250°
Answer:
Each Person:
-In tips: $2
-Food Bill: $7.50
Step-by-step explanation:
Let's find the tip amount for each person. $16 for the whole group. Each person will give in $2 for the tips, for a total of $16 in tips.
Now that tips are done, we must subtract the amount of tips from the food bill, to see how much each person pays. $76 - $16 = $60.
Divide 60 by 8 to get.. 60/8= 7.5.
With 7.5 as an answer, we can conclude that each person paid $7.50 for the food bill.

Answer:
Missing frequency = 4
Step-by-step explanation:
Given:
Qty Number
1 5
2 6
3 5
4 6
5 □
6 5
7 8
8 4
9 4
10 3
Total 50
Find:
Missing frequency
Computation:
Missing frequency = Total frequency - Counted
Missing frequency = 50 - 46
Missing frequency = 4
It is y+1=0.9(x+4) because the formula is y - y1=m(x + x1) you only need one point and the slope. If you have two points, you need to find the slope by using the slope formula slope=y2-y1/x2-x1. Filling it in it would look like slope=7-(-1)/5-(-4). The double negatives cancel each other out and it turns to addition signs leaving us with slope=7+1/5+4 so the slope is 8/9 or 0.9. Now you can fill out the point-slope formula y+1=0.9(x+4)
