Answer:
2(x+5)=2x-3
2x+10=2x-3
2x-2x= -3-10
0= -13
Step-by-step explanation:
Simple,
first find what 19*7 and 3*5 is,
19*7=133
and
3*5=15
Factors in 133:
1,7,19,133
Factors in 15:
1,3,5,15
The GCF of 133 and 15 is 1. You can't simplify/reduce it anymore.
Answer:
b = h cos α.
Step-by-step explanation:
sin β = b / h
b = h sin β.
or cos α = b / h
so b = h cos α.
Answer:
x = 20
Step-by-step explanation:
The two angles inside the triangle added together equals the one other angle that's outside the triangle. Its called an exterior angle.
42° + 5x + 4 = 7x + 6
combine like terms
5x + 46 = 7x + 6
subtract 5x
46 = 2x + 6
subtract 6
40 = 2x
divide by 2
20 = x
Answer: -6 is greater than the left side. So the answer will be less than -6
Step-by-step explanation: for example. The answer could be -7 or -8, (those arent calculated answers)
