Step 1: Rewrite the equation
-14+6b+7-2B=1+5b
Step 2: Combine like terms
-14+6b+7-2b=1+5b
-7+4b=1+5b
Step 3: To isolate b, first add 7 on both sides
-7+4b=1+5b
+7 +7
_________
4b=8+5b
Step 4: Again, trying to isolate b, subtract 5b on both sides
4b=8+5b
-5b -5b
_______
-b=8
Step 5 (final step): Because the variable cannot be negative for a final answer, multiply each number by -1.
-1(-b=8)
b= -8
Final Answer: b=-8
Hope this helps :)
Answer:
the first and second one
Step-by-step explanation:
the two last ones go over budget
1) 20×30=600 30×50=1500 total is 2100
2)50×30=1500 10×50= 500 total is 2000
3) 40×30=1200 40×50=2000 total is 3100>over budget.
4) 20×30=600 60×50=3000 total is 3600> way over budget.
Answer:
37.68
Step-by-step explanation:
volume= πr²h/3
= 3.14x3²x4/3
=3.14x3x4
= 3.14x12
=37.68
Answer:
82.4 cm
Step-by-step explanation:
The computation of the height is given below:
As we know that each right triangle contains the top angle of 20 degrees
So, the right angle & the bottom corner angle equivalent to
= 180 - 90 - 20
= 70 degrees
Now the height is
tangent = opposite leg ÷ adjacent leg
tan (70°) = height ÷ 30 cm
height = 30 cm × tan (70°)
= 82.4 cm
