3x+8.5 =2.5x + 14.5
subtract 2.5x from each side
.5x + 8.5 = 14.5
subtract 8.5 from each side
.5x =6
multiply by 2
x =12
at 12 weeks they will be the same height
Choice B
If you’re asking what x equals, the answer is 15

Conditional statement.</h2>
A mathematical statement of the form 'If A Then B' is a conditional statement.
<h3>
Explanation:</h3>
A conditional statement in geometry is an if-then statement consisting of a hypothesis and a dependent conclusion. The structure of a conditional statement is:
<em>If (......hypothesis......), then (......conclusion......)</em>
If hypothesis = A and conclusion = B, the mathematical expression for a conditional statement is: <u>A → B</u> and it is read as <u>If A then B.</u>
A conditional statement is always true unless the hypothesis is true and the conclusion is false.
A conditional statement can be written in form of its converse, inverse and contrapositive.
<u>Example of a conditional statement is</u>
A = I am 18 years old
B = I am an adult
A conditional statement is of the form (<u>A → B</u>) "If A then B"; therefore
If I am 18 years old, then I am an adult.
