Answer:
The answer is 8x3=24
Step-by-step explanation:
Answer:
<DFG = 51 degrees
<JKL = 39 degrees
Step-by-step explanation:
x + 5 + x - 7 = 90
2x - 2 = 90
2x = 92
x = 46
<DFG = 46+5 = 51 degrees
<JKL = 46-7 = 39 degrees
Answer: The numbers are 5, 8, and 9
Step-by-step explanation:
x+y+z=22
y=x+3
z=2x-1
After you have those three equations, you can plug the y and z value into the first equation.
You get x+x+3+2x-1=22, so 4x+2=22
Therefore, 4x=20, so x=5
If x=8, then y=5+3, so y=8
Also, z=2(5)-1, so z=9
Answer:
-7.5
Step-by-step explanation:
3.5z-2.7z is .8z
.8x=-6
.8 is 4/5
5/4 times .8z=5/4 times -6
-7.5
