Answer:
Step-by-step explanation:
Because x=5y-4 you can substitute 5y-4 into the x in the other equation. This makes 5(5y-4) + 4y = 38. When simplified it gives 25y -20 +4y = 38. Move like terms to each side to get 29y = 58 and get y=2. Then you can substitute 2 into the y in either equation to find x. I will do x=5(2)-4 to get x=6. So x=6 and y=2
Answer:
<em>w= 1</em>
<em>x = 6</em>
Step-by-step explanation:
<em>Congruent Triangles</em>
When two triangles are determined to be congruent, their side lengths and angles have the same measure.
We are given the condition that triangles FGH and ABC are congruent. This implies that sides FH and AC have the same measure, or, equivalently:
x + 12 = 18
Solving:
x = 18 - 12 = 6
x = 6
Similarly, sides HG and CB have the same length, thus:
w + 45 = 46
Solving:
w = 46 - 45 = 1
w= 1
2x-1+3 < 6
+1 < +1
2x+3 < 7
-3 < -3
2x < 4
/2 < /2
x < 2
No Problem!
5p-14=8p+4
I assume this is the whole problem set up properly, so now, lets subtract the left side by 5p, and then the right side.
-14=3p+4
As you can see, the 5p cancels out on the left side, and the p leftover is what 8p-5p equals.
Now, subtract both sides by 4.
-18=3p
Now, simply divide both sides by 3 to equal
p= -6
The reason we do the divide and multiplying last is because doing it first would only make it much harder.
This is the simplest way I know of to do it. If you don't understand, just ask me.
Hope it helped!
