sorry, i have to keep looking back at the photo
for the last question i will be solving ok
At start Keenan has x strawberries. He gives Tisha x/2. Then Tisha keeps 4 strawberries and gives Suvi the rest. If y is the number of strawberries that Suvi gets:
y = x/2 - 4.
For example: Keenan has 20 strawberries. He gives Tisha 10 and Tisha gives Suvi 6:
6 = 20/2 - 4
6 = 10 - 4
Answer:
Step-by-step explanation:
Answer:
(3, 4 )
Step-by-step explanation:
3x - y = 5 → (1)
x + y = 7 → (2)
adding the 2 equations term by term will eliminate y
4x + 0 = 12
4x = 12 ( divide both sides by 4 )
x = 3
substitute x = 3 into either of the 2 equations and solve for y
substituting into (2)
3 + y = 7 ( subtract 3 from both sides )
y = 4
solution is (3, 4 )
Answer:
12
Step-by-step explanation:
13.5 + 0.5n =19.5
0.5n=19.5 - 13.5
0.5n=6
n=6/0.5
n=12
