Answer:
a = 0
Step-by-step explanation:
=> 3(a+4)-5(a-2) = 22
Opening Brackets
=> 3a+12-5a+10 = 22
=> 3a-5a+12+10 = 22
=> -2a+22 = 22
Subtracting 22 to both sides
=> -2a = 0
Dividing both sides by -2
We get,
=> a = 0
Answer:
a = 0
Step-by-step explanation:
3(a+4)-5(a-2)=22
3a+12-5a+10=22
-2a+22=22
<em>Subtract 22 from both sides</em>
-2a=0
<em>Multiply both sides by -1</em>
2a= -0
2a=0
<em>Divide both sides by 2</em>
a=0

Answer:
56.52
Step-by-step explanation:
pi×r²h
=3.14×3²2
=3.14×9×2
=3.14×18
= 56.52³
Answer:
width = w
length= 3w+1
perimeter= 5(3w+1) -45
perimeter = 2(l+b)
5(3w+1) -45 = 2{(3w+1)+w}
15w - 40 = 8w+2
6w = 42
w =7
therefore width = <u>7</u>
length= 3w+1 = <u>22</u>
perimeter= <u>65</u>
Step-by-step explanation:
-3 • (5x + 2y = 7)
-15x - 6y = -21
-2x + 6y = 9
__________
-17x = -12
x = 12/17
5(12/17) + 2y = 7
2y = 7 - 60/17
2y = 3.47
y = 1.735
