Answer:
(7)2+x
Step-by-step explanation:
Seven times 2 plus x if you want to solve for it the answer would be 14x, I think.
Answer:
2 points throw = 37
3 points throw = 11
Step-by-step explanation:
Given that:
Let number of
2 points = x ; 3 points = y
x + y = 48 - - - (1)
2x + 3y = 107 ---(2)
x = 48 - y
Then ;
2(48 - y) + 3y = 107
96 - 2y + 3y = 107
96 + y = 107
y = 107 - 96
y = 11
From (1)
x = 48 - 11
x = 37
2 points throw = 37
3 points throw = 11
Answer:
5 1/3
Step-by-step explanation:
Answer:
147.5 km and 64.4 km
Step-by-step explanation:
a=120 km
b=70 km
β=28 degrees (
∘)
b^2=(a^2)+(c^2)−2ac*cosβ

=(120^2
)+(c^2)−2⋅ 120⋅ c⋅ cos(28∘ )
(c^2
) −211.907c+9500=0
note p, q, and r are replacement variables in the Pythagorean theorem since a, b, and c are already in use
p=1;q=−211.907;r=9500
D=(q^2
