Answer:
6) f=45
7) r=57
Step-by-step explanation:
the angles of a triangle will always add up to 180 degrees. Therefore, for the first one the three inside angles have to be 30, 15, and 135. If 135 is the supplementary angle to f, 45 must be the degree of f.
Same idea for the second one. 180-143=37. so 37+86+r=180. solve for r to get 57.
151 ounces, or 9 pounds 7 ounces
16 ounces = 1 pound
131 ounces = 8.1875 pounds
After 4 weeks Omar gains 20 ounces, which is 1.25 pounds.
8.1875 + 1.25 = 9.4375 pounds
Answer:
Equation: 2x + 1 = 9x - 13
There are two chairs in each row.
Step-by-step explanation:
Looking at the problem, we see that Hue can form two rows of chairs with 1 left over, or 9 rows if she gets 13 more. With that information we can create the equation 2x + 1 = 9x - 13. Now let's solve for x.
2x + 1 = 9x - 13
<em>What we can do first is subtract 9x from both sides. This is done so all of the variables are on one side. Thus that becomes...</em>
2x + 1 - 9x = -13
<em>Now, combine -9x and 2x to get -7x.</em>
-7x + 1 = -13
<em>Now subtract 1 from both sides. This is done so we solve for x directly.</em>
-7x = -13 - 1
<em>Subtract -1 from -13 to get -14.</em>
-7x = -14
<em>Now divide both sides by -7.</em>
x = -14/-7
<em>Divide -14 by -7 to get 2. Remember, dividing two negatives gives you a positive!</em>
x = 2
With that, the equation is solved. There are 2 chairs in each row.
Answer:
5.25 feets
Step-by-step explanation:
Given the question :
Abdul wants to hang a square poster that measure 1 1/2 feet on a side in the center of a 12-foot-long wall. How far from the end of the wall should abdul place the side of the poster?
Length of one side of Square poster = 1 1/2 Feets = 3/2 feets
Length of wall = 12 feets long
Since Abdul wants the poster to be centered in the wall; then the picture should be placed such that there must be equal space left on either side of the wall after hanging.
Hence, (12/2 - 1 1/2) = (6 - 0.75) feets
= 5.25 feets
