Answer:
let there be x children and (481-x) adults.
1.25x +2.25(481-x) = 865.25
1.25x +1082.25 -2.25x =865.25
x= 217
so 217 children and 481-217 = 264 adults

Answer:
70°
Step-by-step explanation:
every triangle has a total of 180°, therefore 180-80-30=70°
i apologize if my answer is incorrect!
Answer:
5.02 pounds
Step-by-step explanation:
y = k*x
Where,
y = weight of a object on Jupiter
x = weight of the object on earth
k = constant of proportionality
An object that weighs 150 ponds on earth would weigh 378.2 ponds on Jupiter.
y = k*x
378.2 = k*150
378.2 = 150k
k = 378.2/150
= 2.5213
Approximately k = 2.52
determine how Much a rock that weigh 12.64 on Jupiter would weigh on earth
y = k*x
12.64 = 2.52*x
12.64 = 2.52x
x = 12.64 / 2.52
= 5.0159
Approximately x = 5.02 pounds
Answer:
Step-by-step explanation:
6x+3
Answer:
To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...
To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
To find the y-intercept, set x = 0 \displaystyle x=0 x=0.
