Answer: 17.75 pounds
Step-by-step explanation:
After putting soil in the first flower bed, Layla's bag was ⅝ full. The pound of soil will be: = 5/8 × 10 = 6.25 pounds
Eliana's bag was ⅖ full. The pound of soil will be: = 2/5 × 10 = 4 pounds
Nature's bag was ¾ full. The pound of soil will be: = 3/4 × 10 = 30/4 = 7.5 pounds
The number of pounds of soil that they put in the first flower bed altogether will be:
= 6.25 + 4 + 7.5
= 17.75 pounds

Answer:
x = 14
Step-by-step explanation:
See the diagram of the triangle attached.
We have Δ RST where, ∠ RST = 7x -54 and ∠ SRT = ∠ STR {Since, given that, RS = ST}
Now, if ∠ STU = 8x, then ∠ STR = 180 - 8x {Since, ∠ STU and ∠ STR are supplementary}
So, ∠ SRT = ∠ STR = 180 - 8x
Now, from Δ SRT, ∠ RST + ∠ SRT + ∠ STR = 180
⇒ 7x - 54 + 180 - 8x + 180 - 8x = 180
⇒ 9x = 126
⇒ x = 14 (Answer)
