Answer:Marcus jogged 7 miles while Elena jogged 8 miles.

Step-by-step explanation:

x + (x+1) = 15

2x+1=15

putting like terms together we get:

2x=15-1

2x=14

hence

x=14/2 = 7miles

therefore we conclude that Marcus jogged 7 miles while Elena jogged 8 miles.

I think it’s right, sorry if I’m wrong...


The square root of 5 is the positive real number that, when multiplied by itself, gives the prime number 5. It is more precisely called the principal square root of 5, to distinguish it from the negative number with the same property. This number appears in the fractional expression for the golden ratio. It can be denoted in surd form as:

It is an irrational algebraic number.[1] The first sixty significant digits of its decimal expansion are:

which can be rounded down to 2.236 to within 99.99% accuracy. The approximation

Alejandro solved the equation 5(7x^2-2)-8=3. He wrote 5(7x^2-2)=11 as his first step. Which property justifies his first step?
Scorpion4ik [409]
The addition property of equality. It says that if you add the same number to each side of the equation, the two sides of the equation will be equal. In this case, the number 8 was added to each side.

Hope this helps :)
