Answer:
x = 6
Step-by-step explanation:
Given
6( - 4 ) = 30 ( divide both sides by 6 )
- 4 = 5 ( add 4 to both sides )
= 9 ( multiply both sides by 2 to clear the fraction )
3x = 18 ( divide both sides by 3 )
x = 6
24 rows, 5 columns
8 rows, 15 columns
40 rows, 3 columns
that's all I can think of
So,
"at least" means that is the minimum acceptable amount. So we will use the "greater than or equal to" symbol.
Let "w" represent the width of the traffic lane.
w ≥ 12 ft.
The larger number is 6 and the smaller one is 2.
If the boy grows another 5 inches, he will be 1/2 as tall as his sister. HIs sister is 68 inch tall
Let sister = g, and boy = b
2b + 5 = g
g = 68
Plug in 68 for g
2b + 5 = 68
Isolate the b. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
first, subtract 5 from both sdies
2b + 5 (-5) = 68 (-5)
2b = 68 - 5
2b = 63
Isolate the b. Divide 2 from both sides
2b/2 = 63/2
b = 63/2
b = 31.5
The boy is 31.5 inches tall
hope this helps
