Answer:

x = 8

Step-by-step explanation:

Step 1: Write equation

5x - 11 = 3x + 5

Step 2: Solve for x

Subtract 3x on both sides: 2x - 11 = 5

Add 11 to both sides: 2x = 16

Divide both sides by 2: x = 8

Step 3: Check

Plug in x to verify it is a solution.

5(8) - 11 = 3(8) + 5

40 - 11 = 24 + 5

29 = 29

the scientist's collection that has granite that weighs 74 26/36 lbs, marble that weighs 63 16/34 lbs, and quartz that weighs 81

Viktor [21]

Answer:

(D)6 1/2 lbs

Step-by-step explanation:

$\text{Weight of the quartz = }81 \dfrac{9}{40} \text{ lbs}\\\dfrac{9}{40}=0.225 \\$Therefore:$ 81 \dfrac{9}{40} \approx 81.25\text{ lbs (to the nearest 1/4 lbs)}\\\text{Weight of the granite = }74 \dfrac{26}{36} \text{ lbs}\\ \dfrac{26}{36}=0.722 \\$Therefore:$74 \dfrac{26}{36} \approx 74.75\text{ lbs (to the nearest 1/4 lbs)}$
