Trisha has $100 to spend on presents for 4 of her friends. She wants to spend the same amount on each friend. How much money can she spend on each friend (x)? *Choose the inequality that best matches this scenario.

a. 4+x ≤ 100

b. 4x ≤ 100

c. x ÷ 100 ≥ 4

d. 100 - x ≥ 4

B

Step-by-step explanation:

Trisha has $100. So she has to spend less than $100 or exactly 100 on her friends. The sign to represent this is ≤ ( the less than or equal to sign )

so if she has 4 friends and wants to spend x on each friend, she would spend a total of 4x on her 4 friends.

Remember that she has to spend less than or equal to $100. The equation to represent this is 4x ≤ 100

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

30 feet

step-by-step explanation:

that would be 2 1/2 * 12

= 24 + 6

= 30 feet   (answer)
