Answer:
Step-by-step explanation:
Remark
They are asking you to combine like terms. The total should be 180.
Givens
2 angles
Total 180
Solution
8x - 3 + 4x + 3 = 180 The threes cancel. So add what's left. They are of opposite signs, so they cancel.
12x = 180 Divide both sides by 12
12x/12 = 180 /12
x = 15
Answer:
Step-by-step explanation :
Ratio = 3x : 4x
<h3>
Sum of angle of a quadrilateral = 360</h3><h3>
Therefore, 140+80+3x+4x = 360</h3><h3>
220+7x = 360</h3><h3>
7x = 360-220</h3><h3>
x= 140/7</h3><h3>
x=20</h3><h3>
3x= 3×20=60</h3><h3>
4x=4×20=80</h3>
Answer:
for #1: 70x = y
for #2: 70x + 100 = y
Step-by-step explanation:
you pay $70 for x amount of time with will equal your total therefore it's 70x = y
if you have to pay a one-time fee of $100.00 then you have to add that to your equation giving you 70x + 100 = y
hope this is right
hope it helps too :)
X+2y=4
3x-2y=4
4x=8
x=2
2+2y=4
2y=2
y=1
y=1
x=2
Hope this helps :)
