Answer:
he needs to play 24 games of basketball
Let the 1st number be x; 2nd number be y; 3rd number be z.
x + y + z = 79
x = number we are looking for.
y = x * 5 ==> 5 times the first
z = x + 16 ==> 16 more than the first
Therefor,
x + (x * 5) + (x+16) = 79
1st step, multiply the 2nd number: x * 5 = 5x
x + 5x + x + 16 = 79
Add all like numbers:
7x + 16 = 79
To get x, transfer 16 to the other side and change its sign from positive to negative.
7x = 79 - 16
7x = 63
To get x, divide both sides by 7
7x/7 = 63/7
x = 9
To check. Substitute x by 9.
x + (x * 5) + (x+16) = 79
9 + (9 * 5) + (9 + 16) = 79
9 + 45 + 25 = 79
79 = 79 equal. value of x is correct.
Answer:
Step-by-step explanation:
=-65*5
=-325
Answer:
name them
A=(-2,5)
B=(-2,1)
C=(1,1)
sides:
AB=c=4
AC=b=√(3²+4²)=5
BC=a=3
then we do this
2p=a+b+c
2p=3+4+5=12
p=6
then we calculate the area:
√(p(p-a)(p-b)(p-c))
Area=√6(6-3)(6-4)(6-5)
Area=√(6×3×2×1)
Area=√36=6
1200
you just do 4 multiplied by 6 to get 24 and then multiply 24 by 50 and you have 1200
