Answer:
Step-by-step explanation:
If the value of y is same for both then we have equal right sides of equations
Solve this for x
- 50x - 30x = 70 - 10
- 20x = 60
- x = 60/20
- x = 3
Find the value of y
- y = 50*3 + 10 = 150 + 10 = 160
Correct choice is A
If one serving is 1/2 a pound and the recipe uses 3/4, then the recipe must be multiplied by 1 1/3 to make 1 pound of chicken - 2 servings
Let the two integers be x and y
x-3= 2y
x=2y+3______(1)
x²+y²= 233_____(2)
sub eqn (1) into (2)
{2y+3}²+y²=233
4y² + 12y +9 +y²=233
5y²+12y+9-233=0
5y²+12y-224=0
y= -8 or 5.6
recall they are positive integers so y=5.6
now sub y=5.6 into eqn (1)
x=2(5.6)+3 = 11.2+3=14.2
the two integers are 14.2 and 5.6
Answer:
Macro receives $12.
Step-by-step explanation:
Let the prize money received by Macro be 3x and that of Justin be 4x.
Justin received $16.
It means,
4x = 16
x = 4
Prize received by Macro = 3x
= 3(4)
= $12
Hence, Macro receives $12.
