Answer:

Equation 2: x - 2y = 1

Step-by-step explanation:

The equations easiest to use substitution are the ones that have the variable multiplied by one, as in the case of Eq. 2 where x is 1x, so if you substitute a zero for x, we know that y has to be -1/2 for the equation to be true. Furthermore, if you substitute a 0 for y you automatically know that x = 1.

If you try to substitute anything for x in equation 1, let's say x = 1, you still have to multipy by 3, then the rest of the problem would be more steps.

Arlecino [84]

Answer:

4(x+4)

Step-by-step explanation:

Find to GCF of 4x+16.

Now factor out the GCF by dividing each term in the expression by 4.

4x divided by the GCF is x, and 16 divided by the GCF is 4.

The equivalent expression is 4(x+4).

A bird is flying at an elevation of 3 5/8 feet above sea level. A fish swims directly under the bird at a depth of 5 1/3 feet be

Stells [14]

Given :

Distance of bird from sea level, $d_1 = 3\dfrac{5}{8} = \dfrac{29}{8}\ feet$ .

Distance between fish and sea level, $d_2=5\dfrac{1}{3}=\dfrac{16}{3}\ feet$ .

To Find :

Distance between bird and fish.

Solution :

Distance between bird and fish is given by :

$D=d_1+d_2\\\\D = \dfrac{29}{8}+\dfrac{16}{3}\\\\D=8.958\ feet$

Therefore, distance between bird and fish is 8.958 feet.

Hence, this is the required solution.
