20. Bc when u solve, you should get x +47=8
To solve this, you would multiply 2 3/8 by 1/4, which is the same thing as dividing by 4. Without a calculator to divide, we must first turn 2 3/8 into an improper fraction. To do this we multiply the whole number of 2 by the denominator of 8 and add the product of 16 to the numerator of 3, which would get us with 19/8 x 1/4. The product would be 19/32, the pounds that each serving weighs.
Answer:
54°
Step-by-step explanation:
Opposite angles of a parallelogram are congruent, so;
![9x+9=8x+14 \\ \\ x=5 \\ \\ m\angle S=9(5)+9=54^{\circ}](https://tex.z-dn.net/?f=9x%2B9%3D8x%2B14%20%5C%5C%20%5C%5C%20x%3D5%20%5C%5C%20%5C%5C%20m%5Cangle%20S%3D9%285%29%2B9%3D54%5E%7B%5Ccirc%7D)
with speed of 18 feet per second the distance between the twins change.
<u>Step-by-step explanation:</u>
Here we have , Two twins are running away from their mother in opposite directions one with the speed of 10 feet per second and the other with the speed of 8 feet per second. We need to find How and with what speed does the distance between the twins change. Let's find out:
Two twins are running in opposite directions , Let us suppose one twin speed is denoted by
, i.e. 10 feet per second
⇒ ![v_1=10](https://tex.z-dn.net/?f=v_1%3D10)
Now , Speed of other twin is
, i.e. -8 feet per second . Minus sign shows the direction as this twin is moving in opposite direction :
⇒ ![v_2=-8](https://tex.z-dn.net/?f=v_2%3D-8)
Now, Difference in both speeds will give the change in speed between them :
⇒ ![v_1-v_2=10-(-8)](https://tex.z-dn.net/?f=v_1-v_2%3D10-%28-8%29)
⇒ ![v_1-v_2=18](https://tex.z-dn.net/?f=v_1-v_2%3D18)
Therefore , with speed of 18 feet per second the distance between the twins change.
