Here's one way:
A=WxL
So in this case, it's 2x5
You would draw the rectangle, label one side 2 in. and the other 5 in. Draw an arrow from each no./side and put x underneath the line so that its 2 —x— 5 (2, line, x, line, 5. With x under line)
8x-19=-3x-41
+3x +3x
11x-19=-41
+19 +19
11x=-22
÷11 ÷11
x=-2
30% of the 30 marbles is nine and 9-30 = 21 so your answer is 21
The missing numbers would be 12-6
Answer:
x = 1
Step-by-step explanation:
Our goal is to isolate x on one side. So:
-6 +5x = 6x - 7
-6 = x - 7
1 = x
