Answer:
I speak English.
Step-by-step explanation:
I am from America.
5+7+8=20 which is the total number of balls that the bag contains
because out of the 20 balls only the 8 are blue, it is right to say that
8/20 = x/100 ⇒ x= (8·100)/20 ⇒ x= 800/20 ⇒ x=40
the blue balls are the 40%
Answer:
(1, 4 )
Step-by-step explanation:
Given the 2 equations
y = x + 3 → (1)
y = 4x → (2)
Substitute y = 4x into (1)
4x = x + 3 ( subtract x from both sides )
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into (2)
y = 4x = 4 × 1 = 4
Solution is (1, 4 )
