Answer:
10*5 = 7x
Step-by-step explanation:
We can solve using cross products
10*5 = 7x
50 = 7x
divide each side by 7
50/7 =7x/7
50/7 =x
Answer:
fourth option
Step-by-step explanation:
let t be tennis balls and g be golf balls, then
5t + 3g = 70 → (1)
2t + 5g = 85 → (2)
Multiplying (1) by 5 and (2) by - 3 will eliminate g
25t + 15g = 350 → (3)
- 6t - 15g = - 255 → (4)
Add (3) and (4) term by term to eliminate g
19t = 95 ( divide both sides by 19 )
t = 5
Substitute t = 5 into either of the 2 equations and solve for g
Substituting into (1)
5(5) + 3g = 70
25 + 3g = 70 ( subtract 25 from both sides )
3g = 45 ( divide both sides by 3 )
g = 15
Thus
$5 for tennis balls and $15 for golf balls
Answer:
x¹²y¹¹/6
Step-by-step explanation:
cancel 18 by 3,then minus the x¹⁴ to the 18²
but you don't have to do something on y¹¹
check the picture below.
make sure your calculator is in Degree mode.
