Winston needs at least 80 signatures from students in his school before he can run for class president. he has 23 signatures already. he and his two friends plan to get the remaining signatures during lunch. if each person gets the same number of signatures, which inequality can winston use to determine the minimum number of signatures each person should get so he can run for class president?

each person needs to get at least 19 signutures more.

hopefully this helps.

The inequality would be 3x ≥ 80 - 23, which simplifies to x ≥ 19

Step-by-step explanation:

In this equation, x would be for each student. Since there are 3 students, we know that we can multiply their number by 3. We also know they need 23 less than 80. After creating this equation, we can solve.

3x ≥ 80 - 23

3x ≥ 57

x ≥ 19

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3
