Answer:

2 possible answers

Step-by-step explanation:

Assumption: 178 wore black (that means some may wear gold + black aka as long as they wore abit of black, it's counted):

since there are 257 students and 34 wore both gold and black, and 178 wore black, the number of students who wore only black = 178 - 34 = 144

no of students who wore only gold = 257 - 144 - 34 = 79

Assumption: 178 students wore ONLY black:

no of students who wore only gold: 257 - 178 - 34 = 45

Answer:

Yes

Step-by-step explanation:

If you find the value of all the angles, you'll find that both triangles' angles are 50, 35, and 90 degrees.

(all the angles in a triangle add up to 180)

Solve the equation 5x + 7y = 35 for y.
erastovalidia [21]

Answer:

D. y = -5/7x + 5

Step-by-step explanation:

5x + 7y = 35

-5x          -5x

7y =  35 - 5x

/7      /7    /7

y = 35/7 - 5/7 x

y = 5 - 5/7x

Answer:

n=27 degrees

m=36 degrees

Step-by-step explanation:

So the inside triangle has two equal sides. To find these angles you would do the degrees of a triangle (180) minus the known value and then divided by two.

so it is: 180-126/2 which gives you 27 degrees.

this means the n value is 27.

to find m, you have to take away 90 degrees and the n value from 180.

so it is: 180-90-27 which gives you 63 degrees.

now you must take the smaller angle from 63 degrees to find m.

so it is: 63-27 which gives you 36

therefore...

n=27 degrees

m=36 degrees

What is 0.06x-0.18=0.12
MAXImum [283]
Hi there!

To solve this problem, we should simplify.

0.06x - 0.18 = 0.12

First, we should add 0.18 to both sides:

0.06x = 0.12 + 0.18
0.06x = 0.3

Now, we can convert 0.06 into a fraction and multiply both sides of the equation by its receprical to isolate x:

0.06 = 6/100
6/100 × 100/6 = 1
0.3 × 100/6 = 30/6
x = 30/6
x = 15/3
x = 5

So, x is 5.

Hope this helps!
