3x-4=-19
you add -4 to both sides and get 3x=15 then divide 3 by both sides and get x=5 (15 divided by 3 is 5)
Answer:
18/8 = x/3
x = 6.75 inches (length)
Step-by-step explanation:
Hi, to answer this question we have to write 2 ratios using the information given:
A larger rectangle has a length of 18 inches and width of 8 inches.
Inches /width = 18/8
So, for a rectangle that has a length of x inches and width of 3 inches the ratio is :
x/3
Solving for x:
18/8 = x/3
18/8 (3) =x
6.75 in= x

Simplifying:
2t+-7=1
Reorder the terms:
-7+2t=1
Solving variable for "t."
Move all terms containing "t" to the left
Add "7" to each side of the equation
-7+7+2+=1+7
Combine the terms
-7+7=0
0+2+=1+7
2t=17
Combine the like terms:
1+7=8
2t=8
Divide each side by 2. You now have: t=4
Good luck, hope this helped! :)
