You would add like terms so it would be 1x then you add 1 to 7 so you would get 8.. the you divide both sides by 1x and you'd get 8=x

Answer:  x = 8

−2x − 1 + 3x =7

−2x + −1 + 3x =7

(−2x+3x) + (−1) =7 (Combine Like Terms)

x+ −1 =7

x−1=7

Step 2: Add 1 to both sides.

x−1+1=7+1

x=8

8. Colby and Cheryl work in different local supermarkets. Colby regularly earns $8.90 per hour,
faust18 [17]

Answer:

colby

hourly rate =$8.90

overtime rate = time and a half = 1.5

the hourly overtime rate is the product of the overtime rate and the hourly rate.

hourly overtime rate= overtime rate × hourly rate

= 1.5 × $8.90

= $13.35

Cheryl

hourly rate = $7.10

overtime rate = double time = 2

the hourly overtime rate is the product of overtime rate and the hourly rate.

hourly overtime rate = overtime rate × hourly rate

= 2 × $7.10

= $14.20

<h3>Comparison</h3>

we note that the hourly overtime rate of cheryl is higher than the hourly overtime rate of colby, which implies that cheryl earns more for one hour of overtime.

we are also interested in the difference of the hourly overtime rate:

hourly overtime rate colby — hourly overtime rate cheryl

= $14.20 – $13.35

= $0.85

thus cheryl earns $0.85 more for one hour of overtime than colby .

<h3>result</h3>

<h2>cheryl,$0.85</h2>

At what depth in the ocean are aquatic plants able to produce the most sugar using photosynthesis?
ivann1987 [24]
In the process of photosynthesis, one of the most important ingredient would be sunlight. Therefore, those aquatic plants that are near the surface would be able to produce the most sugar. This is because they can easily absorb sunlight compared to those that are located deeper in the water. Hope this helps.
