<span>find the range. [15(35)]+[12(60)] and this will be your high end. now do it again but at the low end [15(20)]+[12(30)] and this will be your low end. now you have the max amount the price would be and the lowest amount of the price. now look at your answers and see what is within that range and what isn't and there's your answer.</span>
Answer:
the two angles are 55° each
Step-by-step explanation:
Let the two equal angles be y each
Therefore,
70° + y + y = 180°
Collect like terms
2y = 180 — 70
2y = 110
Divide both side by the coefficient of y i.e 2
y = 110/2
y = 55°
Therefore, the two angles are 55° each
Answer:
x=-4
Step-by-step explanation:
-2x+18-1x+4=34
step 1 combine like terms
-2x+-1x=-3x
18+4=22
-3x+22=34
step 2 subtract each side by 22
-3x=12
step 3 divide each side by -3
x=-4
hope this helps (:
0.42z = 2.52
z = 2.52 / 0.42
z = 6
same as
z + 7.45 = 13.45
z = 13.45 - 7.45
z = 6
answer is top right z + 7.45 = 13.45
Answer: -x - 3√x + 4
(1 - √x)(√x + 4)
= √x + 4 - √x.√x - 4√x
= -x - 3√x + 4
