6.2w = 18.6....divide both sides by 6.2
w = 18.6 / 6.2

Find a solution to the system. Make sure to write as a coordinate.
RUDIKE [14]

Answer:

x=2, y=3

Step-by-step explanation:

This is a <u>system of equations</u>.

To solve a system of equations, we use the substitution method.

We can plug in the first equation, x=2y-4, into the value for <em>x</em> in the second equation. Now, the second equation looks like this:

2*(2y-4)+y=7

We simplify and solve for <em>y</em>:

→ 4y-8+y=7

→ 5y=15

→ y=3

Now, we plug in the value for <em>y</em>, which is 3, into either equation. I will just use the first equation:

→ x=2*3-4

→ x = 2

Let me know if my explanation is unclear.

(d) Jim walks three miles in 45 minutes. How long does it take for him to walk 5 miles?​
kramer

Answer:

  • 5 miles = 75 minutes

Step-by-step explanation:

<u>We know that:</u>

  • 3 miles = 45 minutes

<u>Solution:</u>

  • 3 miles = 45 minutes
  • => 1 mile = 45/3 minutes
  • => 5 miles = 45/3 x 5
  • => 5 miles = 15 x 5
  • => 5 miles = 75 minutes

Hence, it takes 75 minutes for Jim to walk 5 miles.

She needs 3/4 cup of water she needs 10 more servings what's the answer A 1/1/5 b 3/1/4 c 7/2/4 d 8/2/3
Eddi Din [679]
<h2><u>Corect option</u> :</h2>

= \color{plum}\tt(C) 7 \frac{2}{4}

<h2><u>Answer with steps</u> :</h2>

Quantity of water she needs = \tt \frac{3}{4} \:  cup

Number of servings she needs = 10

Number of cups of water she will need :

= \tt \frac{3}{4} \:   \times 10

=  \tt\frac{30}{4}

=\tt  7\frac{2}{4} \:  cups

Thus, she needs \tt  7\frac{2}{4} \:  cups of water.

Therefore, the correct option is \color{plum}\tt(C) 7 \frac{2}{4}
