Does (3x+5)+5x+7=180?? and if it does what is the value of x?
Ostrovityanka [42]

Answer:  

x=21

Step-by-step explanation:

Let's solve your equation step-by-step.

3x+5+5x+7=180

Step 1: Simplify both sides of the equation.

3x+5+5x+7=180

(3x+5x)+(5+7)=180(Combine Like Terms)

8x+12=180

8x+12=180

Step 2: Subtract 12 from both sides.

8x+12−12=180−12

8x=168

Step 3: Divide both sides by 8.

8x /8 = 168 /8

x=21

The function c(s) gives the number of corn ears a farmer can harvest by planting s number of seeds. Each statement below can be
aleksandr82 [10.1K]

1. c(800)=600 has same meaning as after planting 800 seeds, there will be 600 corn ears.

2. c(200) = e has the same meaning as there will be e corn ears when 200 seeds are planted.

3. c(s) = 900 has same meaning as the number of corn ears is 900 when s seeds are planted.

Step-by-step explanation:

According to given statement;

c(s) = Number of corn ears

s = Number of seeds

1. After planting 800 seeds, there will be 600 corn ears.

Here,

Number of seeds = s = 800

Number of corn ears = 600

Putting in function

c(800) = 600

c(800)=600 has same meaning as after planting 800 seeds, there will be 600 corn ears.

2. There will be e corn ears, when 200 seeds are planted.

Number of seeds = s = 200

Number of corn ears = e

Putting in function

c(200) = e

c(200) = e has the same meaning as there will be e corn ears when 200 seeds are planted.

3. The number of corn ears is 900 when s seeds are planted.

Number of seeds = s

Number of corn ears = 900

Putting in function

c(s) = 900

c(s) = 900 has same meaning as the number of corn ears is 900 when s seeds are planted.
