6x + 4 = 118
= 6x + 4 - 4 = 118 - 4 ( subtracting both sides by 4)
= 6x = 114
= 6x/6 = 114/6 ( dividing by 6 on both sides )
= x = 19
I think its saying find a side that has no numbers or has a letters. figure out the whole shape then subtract the sides we do know and theres your answer. And if its a decimal round the decimal to the nearest tenth
You need to round 6.018 to 6 then multiply it by 9 which results in 54!
Answer:
Step-by-step explanation:
Let's say the Physics book costs $x
The Chemistry book will cost $x - $6
Two such Chemistry books will cost;
2($x - $6) = $(2x - 12)
Three such Physics books cost $3x
$(2x - 12) + $3x = $123
$5x - $12 = $123
$5x = $111
x = $22
So the Physics book costs; $22
and the Chemistry book costs $22 - 6 = $16
Answer:
70 and 110
Step-by-step explanation:
First angle -- 2x
Second angle -- 3x + 5
Therefore,
2x + 3x + 5 = 180
5x = 175
x = 35
Therefore, 2x -- 70
3x + 5 -------------110
Thenks and mark me brainliest :)
