Answer:
The equation that represents this situation is x + 3x + (x - 4) + 2(x - 4) = 72, where x is Erik's age
Step-by-step explanation:
Let us solve the question
Assume that Erik is x years old
∵ Erik is x years old
∵ Erik is as old as Dawn
→ That means x = Dawn
∴ x = Dawn
→ Multiply both sides by 3
∴ 3x = Dawn
∴ Dawn is 3x years old
∵ Jiro is 4 years younger than Erik
→ That means Jiro = x - 4
∴ Jiro is (x - 4) years old
∵ Alita is 2 times as old as Jiro
→ That means Alita = 2 × (x - 4)
∴ Alita = 2 × (x - 4)
∴ Alita is 2(x - 4) years old
∵ The sum of all their ages is 72
→ That means add their ages and equate the sum by 72
∴ Erike's age + Dawn's age + Jiro's age + Alita's age = 72
∴ x + 3x + (x - 4) + 2(x - 4) = 72
The equation that represents this situation is x + 3x + (x - 4) + 2(x - 4) = 72, where x is Erik's age
First, let's deal with the fraction in the denominator of the exponent. Multiply the top and bottom of the exponent by 6.
Now that the fraction in the denominator is taken care of, we can reduce the denominator.
. Some professors might accept this as simplest form, but others might ask you to get rid of the negative.
Answer:
PS=
Step-by-step explanation:
Given : PQRS is a trapezoid on a coordinate plane P(7,4) Q(10,4) R(13,-1) S(8,-1).
To find:: Length of the side PS
Solution : Using the distance formula, we can find the length of the side PS, therefore
PS=
PS=
PS=
PS=
PS=
which is the required length of the side PS.
Answer:
Step-by-step explanation:
A parallel line will have the same slope as the reference line. In this case, I don't see the "given line" as promised in the question. If it does appear, and it looks like y = 5x + 3, for example, the slope is 5 and the new line will have the same slope.
<h3><u>If this slope is correct</u>, we can start the equation for the parallel line that goes through point (-3,2) by starting with:</h3><h3 /><h3>y = 5x + b</h3><h3 /><h3>We need a value of b that forces the line to go through point (-3,2). We can do that by using the given point in the equation and solving for b:</h3><h3>y = 5x + b</h3><h3>2 = 5(-3) + b</h3><h3>b = 17</h3><h3 /><h3>The parallel line to y=5x+3 is</h3><h3>y = 5x + 17</h3><h3 /><h3>See attachment.</h3><h3 /><h3 /><h3 />
