7 0

Answer:

35 2-point questions, and 15 5-point questions

Assume x 2-points question, so 50-x 5-points question

Total no of points: 2*x+5*(50-x)=145 points

2x+250-5x=145

-3x=-105

x=-105/-3=35 2-points questions

Remaining 50-35=15 5-points questions

ok so i really hope this helped and if it didn't then sorry

56 times a number minus 13 is equal to 6 less than the number.
Elena L [17]

Answer:

The equation is 56x - 13 = x - 6

Step-by-step explanation:

Let's say our 'number' is x. If it says it's 56 times our number, it's 56x. Minus 13, which is 56x - 13. If it is equal than 6 less than the number, then it is x - 6.

So the equation is 56x - 13 = x - 6

PLSSS HELPPP I AM SO CONFUSED AND STUCH HOW TO THIS il mark you as brainlist its about volume and percents
Oliga [24]
First we find the volume of the triangular prism.

We find the area of the triangle, then we multiply that by the height.

So 7*6/2= 42/2=21

21*10= 210

Then if all the dimensions add another foot on to them then you get: 7, 8, and 11.

Then you do the same thing to find the area of this rectangular prism.

7*8/2=56/2=28

28*11= 308

Now, we calculate the growth from 210 to 308 in this proportion: 308/210=x/100

Solving it we get (cross multiplying):

210x=30800

x=146 2/3 or 146.66 percent increase.

I hope this helps!
