A triangle has 180 degrees. 28.5 + 104.25 is 132.75 degrees. 180 - 132.75 is 47.25 degrees.
Answer: x=−5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−4−7x=31
−4+−7x=31
−7x−4=31
Step 2: Add 4 to both sides.
−7x−4+4=31+4
−7x=35
Step 3: Divide both sides by -7.
−7x
−7
=
35
−7
x=−5
I would recommend starting by turning 172 into 100+70+2. This makes it much easier to multiply it by 6.
(100+70+2) × 6 =
distributive property
(100×6) + (70×6) + (2×6) =
Simplify
600 + 420 + 12 =
Add it all together
1032
The answer would be 1032.
Answer: -2.8
Step-by-step explanation:
3t-(8/5) * 4-t < -7
(15t-8)/5 * 4-t < -7
((15t-8)(4-t))/5 < -7
(15t^2)-28t-32< -7
(15t^2)-28t-32-7< 0
(15t^2)-28t-39< 0
Using the quadratic/almighty formula
t= (-b +- ((b^2)-4ac)^(1/2)/2a)
a=15, b=-28, c=-39
t= (-(28) +- (((-28)^2)-4(15)(-39))^(1/2))/2(15))
t= -2.8 or t= 0.9
Since
t<0, then t= -2.8
