In order to solve this mathematical problem we can first
consolidate and observe the given values and the values that are not known in
the stated problem.
Annie traveled 5 times the sum of the number of hours Brian
traveled and 2. Together they traveled 20 hours. Find the numbers.
Equation,
<span><span>
1. </span><span> 5(y) + 2 = 20</span></span>
<span><span>2. </span><span> 5y = 20 – 2</span></span>
<span><span>
3. </span><span> 5y = 18</span></span>
<span><span>4. </span><span> Y = 18 / 5</span></span>
<span><span>
5. </span><span> Y = 3.6</span></span>
<span><span>
6. </span><span> 5y = 5(3.6)</span></span>
<span><span>
7. </span><span> Annie = 18</span></span>
Hence, Annie traveled 18 hours while Brian traveled 3.6
hours.
Answer:
Step-by-step explanation:
You are supposed to pull out the common factor and put it outside the brackets.
42: 6 * 7
54: 6 * 9
So the answer is
6(9 + 7)
The given ratios 3: 5 and 15: 25 are equal. Because when you divide the ratio 15: 25 by 5 on both numerator and denominator, the first ratio 3: 5 can be obtained. Similarly, when you multiply the first ratio 3: 5 by 5, the ratio 15: 25 can be obtained.
Answer:
1
Step-by-step explanation:
Substitute the value of the variable into the expression and simplify.
4-2-1=1
If human development really does proceed continuously, what value does stage theories of development have?
Answer:
Even if human development is continuous, there is some value in stage theories of development. A stage theory of development allows experts to examine the developmental progress of individuals and establish a basis for developmental changes. This can help identify developmental issues earlier. Stage theories can also help researchers who are examining physical development examine discrete changes in the brain that allow certain developmental milestones to be reached. Finally, stage theories can give one a sense of where an individual is developmentally, and can prepare the person for changes that may occur during their lifetime.
