it should be 14 becuse 7 times 2 is 14 so x=14 i took the test
Answer:
x = -1
y = 1
Step-by-step explanation:
y = x + 2
y = 3x + 4
since both of these equal y, you can rewrite this as one equation:
x + 2 = 3x + 4
<em>subtract x from both sides of the equation</em>
2 = 3x + 4 - x
2 = 2x + 4
subtract 4 from both sides of the equation
2 - 4 = 2x
-2 = 2x
<em>divide both sides of the equation by 2</em>
-2/2 = x
-1 = x
now you can plug this back into the original equation to find y.
y = x + 2
y = -1 + 2
y = 1
Answer: The fraction of set of twins=
The fraction of sets of triplets=
The fraction of set of quadruplets=
Step-by-step explanation:
Given: The number of set of twins=5
The number sets of triplets = 2
The number of set of quadruplets=1
⇒ The total number of multiple birth students =5+2+1=8
∴ The fraction of set of twins=
∴ The fraction of sets of triplets=
∴ The fraction of set of quadruplets=
