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:
X is 1 y is -4
Which gets the following:
X(1) + y(-4) = -3
x(1) + 2(-4) = -7
Answer:
450 feet at ground level
Step-by-step explanation:
The width of the bridge at ground level will be where the function intercepts the x-axis also known as the roots or zeros of the function. They are found using the zero product property to set each factor equal to 0.
This means (x-225) = 0 and (x + 225) = 0. So x = -225, 225.
This means the width is the absolute value of |-225| + 225 since distance cannot be negative. This makes it 450 feet.
The constant of proportionality is equal to k in y=kx. In y=10x, the k value is 10.
Final answer: C. 10
