Answer:
x = - 12 6/7
Step-by-step explanation:
x - 12x/5= 18
Get a common denominator on the left
5/5 x -12/5x = 18
Subtract
-7/5 x = 18
Multiply each side by -5/7 to isolate x
-5/7 *-7/5 x = -5/7 *18
x = -5*18/7
x = -90/7
Changing this to a mixed number
7 goes into 90 1 2 times with 6 left over
x = - 12 6/7
Answer:
the third option would be the best
Step-by-step explanation:
2/7 + 3/8 = 37/56 = .660
1/10 + 3/8 = 19/40 = .475
correct answer------------ 1/6 + 1/8 = 7/24 = .291
2/9 + 1/8 = 25/72 = .347
Answer:
7 inches
Step-by-step explanation:
The area of a triangle is found by
A = 1/2 bh
We know the height is 18 and the area is 63
63 = 1/2 (b)(18)
63 = 9b
Divide each side by 9
63/9 = 9b/9
7 = b
The base is 7 inches
Answer:
- a) AB = 10 units
- b) Midpoint is (2, 6)
===================
<h3 /><h3>Given</h3>
- Points A( - 1, 10) and B(5, 2)
<h3>To find</h3>
- a) The length of AB
- b) The midpoint of AB
<h3>Solution</h3>
a) Use the distance formula:
Substitute the coordinates and calculate:
The distance is AB = 10 units
b) Use midpoint formula and find x and y- coordinates of this point:
and 
Substitute coordinates and find the midpoint:
and 
The midpoint is (2, 6)
