The answer is x=-22/69
If you need the step by step let me know.
7x+15=38
7x=38-15
7x=23
x=23/7
Answer:
b= 352/3
or b= 117.33
Step-by-step explanation:
262-3x+85=-5
-3x+(262+85)=-5
simplify the arithmetic
-3x+347=-5
Group all constants on the right side of the equation
-3x+347=-5
Subtract from both sides:
-3x+347-347=-5-347
Simplify the arithmetic:
-3x=-5-347
-3x=-352
isolate the x
-3x=-352
Divide both sides by -3
-3x/-3}=-352/-3}
Cancel out the negatives
3x/3}=-352/-3
Simplify the fraction
x= -352/-3
Cancel out the negatives
x=352/3
Answer:
See Below.
Step-by-step explanation:
We are given that ΔAPB and ΔAQC are equilateral triangles.
And we want to prove that PC = BQ.
Since ΔAPB and ΔAQC are equilateral triangles, this means that:

Likewise:

Since they all measure 60°.
Note that ∠PAC is the addition of the angles ∠PAB and ∠BAC. So:

Likewise:

Since ∠QAC ≅ ∠PAB:

And by substitution:

Thus:

Then by SAS Congruence:

And by CPCTC:

.21 times 611=128.31
128.31 plus 611
739.31
