Answer:
D
Step-by-step explanation:
Let's solve your equation step-by-step.
75+50x=25+70x
Step 1: Simplify both sides of the equation.
50x+75=70x+25
Step 2: Subtract 70x from both sides.
50x+75−70x=70x+25−70x
−20x+75=25
Step 3: Subtract 75 from both sides.
−20x+75−75=25−75
−20x=−50
Step 4: Divide both sides by -20.
−20x
−20
=
−50
−20
x= 5/2
Answer:
12mph + bmph = 45 - 26.5c
Step-by-step explanation:
Perimeter (P) = 2L + 2w
68 = 2L + 2w
68 - 2L = 2w
2(34 - L) = 2(w)
34 - L = w
********************
Area (A) = L * w
240 = L (34 - L)
240 = 34L - L²
L² - 34L + 240 = 0
(L - 10)(L - 24) = 0
L = 10 or L = 24
w = 34 - L = 34 - 10 = 24 or w = 34 - 24 = 10
Answer: width = 10, length = 24 assuming length is bigger than the width
elg=124°
eld=2x
elg+eld=180°=>eld=180°-124°=56°/eld=2x=56°=>x=56°/2=28°
eld+dlh=180°=>dlh=180°-56°=124°
hlg+dlh=180°=>hlg=180°-124°=56°
The answer would be 46,47,48,49
