2 1/8 - 1 2/7 = ?
8*2+1/8 - 7*1+2/7 =
17/8 + 9/7 =
8,7 | 2
4,7 | 2
2,7 | 2
1, 7 | 7
1, 1 | 1_______ 2*2*2*7 = 56
17/8 + 9/7 =
56÷8*17/56 + 56÷7*9/56 =
7*17/56 + 8*9/56 =
119/56 + 72/56 = 191/56
Answer:
191/56
Answer:
<u><em>D. 95</em></u>
Step-by-step explanation:
The average is also known as the mean. To find the mean, you need to add all the values, then divide them by the number of terms:
1 2 3
1+2+3
6/3=2
The mean for the example would be 2. Now, using your values, you can use the options to see which one gives you an average of 90:
A.) 85
B.) 90
C.) 92
D.) 95
The next score on the quiz needs to be 90 for the mean to be 90.
Answer:
<em>A. minus 10,</em>
Step-by-step explanation:
The distance travelled must be positive.
Therefore minus 10 would not be a reasonable answer.
Answer:
what
Step-by-step explanation:
Answer:
Angle I = 90 degrees
Angle J = 61 degrees
Angle K = 29 degrees
Step-by-step explanation:
Angle I is given
We know that the angles in all triangles add up to 180. Since we are given that angle I is equal to 90 degrees, we now know that angle J + angle K = 90 degrees:
(5x+26) + (2x+15) = 90
Solve for X:
7x + 41 = 90
7x = 49
x = 7
Angle J = (5x + 26) = (5(7) + 26) = 61
Angle K = (2x + 15) = (2(7) + 15) = 29
Checking your work: 61 + 29 = 90
