So the ratios are 5:5 and 3:5 so the fractions are 5/10 (1/2) for 7th grade and 5/8 for 8th grade
4*2=8. 8/2.5=3.2. The height is 3.2 meters.
Answer:
10/3
Step-by-step explanation:
-1(6h + 7) = -6h - 7
-6h - 7 + 8 = -6h + 1
-6h + 1 = -19
-1 -1 <em>- Subtract 1 from both sides.</em>
-6h = -20
-6 -6<em> - Divide both sides by negative 6</em>
h = 10/3
