Find x x+4+4x-8+7x-35=180

Mathematics

Answer:

x = 73/4

Step-by-step explanation:

Solve for x:

12 x - 39 = 180

Add 39 to both sides:

12 x + (39 - 39) = 39 + 180

39 - 39 = 0:

12 x = 180 + 39

180 + 39 = 219:

12 x = 219

Divide both sides of 12 x = 219 by 12:

(12 x)/12 = 219/12

12/12 = 1:

x = 219/12

The gcd of 219 and 12 is 3, so 219/12 = (3×73)/(3×4) = 3/3×73/4 = 73/4:

Answer:  x = 73/4

the ratio of girls to boys in the sixth grade is 5:3. If there are 400 sixth graders, how many boys are there?
PilotLPTM [1.2K]

Answer:

boys = 250

girls = 150

Step-by-step explanation:

5g = 3b       eq. 1

g + b = 400       eq. 2

g = girls

b = boys

From the eq. 2

g = 400 - b

Replacing this last eq. on eq. 1:

5(400-b) = 3b

5*400 + 5*-b = 3b

2000 - 5b = 3b

2000 = 3b + 5b

2000 = 8b

2000/8 = b

250 = b

From eq. 2

g + 250 = 400

g = 400 - 250

g = 150

Check:

from eq. 1

5*150 = 3*250  = 750
