Therefore
(4y+6) +y = 46
We can combine the like terms:
5y + 6 = 46
Subtract 6 on both sides:
5y+6-6=46-6
Therefore 5y =40
Divide by 5 on both sides
5y/5 = 40/5
Therefore
y= 8
We found y but to find the value x we use y.
X= 4y+6
Therefore
x= (4*8)+ 6
Therefore
x= 32 + 6
x= 38.
Step-by-step explanation:
I think the answer would be
=1/31 and 1/31
Remember to distribute invibile -1
simlify 2nd part
-(a^2-3a+7)=-1(a^2-3a+7)=-a^2+3a-7
now we have
3a^2+2a-2-a^2+3a-7=
3a^2-a^2+2a+3a-2-7=
2a^2+5a-9
I’m not sure but you can use a calculator I saw a fantasy one at Walmart with A SCREEN ON IT!??? it’s $100 but it would probably help ALOT
Answer:
Length is 26, width is 7
Step-by-step explanation:
Supposing y= width and x= length
We know from the question that
y= 1/2x -1
And the perimeter of any rectangle is 2y + 2x
Substitute y for 1/2x-1
2(1/2x-1) + 2x = 46
x - 2 + 2x = 46
3x = 48
x= 16
y= (1/2*16)-1
y=7
