Answer:
JM = 20
Step-by-step explanation:
Find the value of JM
Using similar triangles;
MJ/HN = GJ/HK
GJ+JM/HN = GJ/HK
15+JM/12+16 = 15/12
15+JM/28 = 15/12
Cross multiply
12(15+JM) = 15*28
180+12JM = 420
12JM = 420 - 180
12JM = 240
JM = 240/12
JM = 20
<em>Hence the length of JM is 20</em>
h = 6
Work Shown:
4h + 6 = 30
1. 4h + 6 -6 = 30 - 6 ---> 4h = 24
2. 4h /4= 24/4 ---> 6
h = 6
Answer:
648 inches
Step-by-step explanation:
12 + 6 = 18 yards
there are 36 inches in 1 yard
so there is 648 inches in 18 yards
Answer:
The ordered pair (4,1) gives a true statement for both equations.
Step-by-step explanation:
So for the first equation, x + 2y = 6. The ordered pair is (4,1). This means x=4 and y=1 because ordered pairs are in (x,y) form. First substitute the x and y values into the first equation
Let x=4 y=1
x + 2y = 6.
4 + 2(1) = 6
4 + 2 = 6
6=6. This means that the ordered pair works for the first equation.
Now, the second equation. x - y = 3.
Again, substitute the x and y values.
4 - 1 = 3
3=3. This means that the ordered pair (4,1) works for the second equation.
The ordered pair (4,1) gives a true statement for both equations.
