Answer:

29.5 inches

Step-by-step explanation:

Eva is 1.5 inches shorter than half of Maria's height, so to determine Eva's height, we would subtract 1.5 from 31, half of Maria's height. Our difference is 29.5. Eva is 29.5 inches tall.

of the 400 of the sixth graders at school, 60% want more library books. how many students want library books?

Answers

Answer:

240

Step-by-step explanation:

it’s simple math!

Since 60% of the 400 kids want more Library books, all you need to do is:

100% - 60% = 40%

find 40% of 400:

400 x 0.4 = 160

then subtract 160 from 400 to get 60%:

400 - 160 = 240

therefore 240 is your answer! :)

3x + 5y + 10
5x - 3y = -6

Answers

Answer:

3x + 5y + 10= 3

5x - 3y = -6

Step-by-step explanation:

1. m=-3/5

2. Simplifying

5x + -3y = 6

Solving

5x + -3y = 6

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3y' to each side of the equation.

5x + -3y + 3y = 6 + 3y

Combine like terms: -3y + 3y = 0

5x + 0 = 6 + 3y

5x = 6 + 3y

Divide each side by '5'.

x = 1.2 + 0.6y

Simplifying

x = 1.2 + 0.6y

Hope this helps

X=1.2+0.6y this is the answer

Lynn put 3 7/8 gallons of gas in her gas tank. If there are now 18 1/6 gallons in the tank, how many gallons did she start with?
x - gallons she started with

Answers

Answer:

14.3 gallons      = 4 + 7.25/25  or 14.29 gallons.

Explanation:

18 1/6 gallons - 3 7/8 = 14.29

18 - 3 = 15

1/6 - 7/8 = 15 - 0.70833333333 = 14.2916666667

You need to be careful here if you use basic subtraction, simply as two minus would change to addition.

First change the mixed number of gallons into improper fractions.

3 7/8 ——> 31/8
18 1/6 ——> 109/6

Then find the LCM ( Lowest Common Multiple) in this case of the denominators it would be 24.

Convert both fractions as a factor of 24;

31/8 ——> 93/24
109/6 ——> 436/24

Then you want to take away the amount she was left with from how many she had added;

436 93 343
——— minus ——— = ———
24 24 24


As a mixed number this could be written

7
as 14 —-
24

A parabola with no real zeros, a negative leading coefficient, and an odd y-intercept.
pls help!

Answers

Answer:

Step-by-step explanation:

A parabolic graph with no real zeros never touches or crosses the x-axis.  

If the leading coefficient is negative, that tells us that the parabola opens down (and, in this case, that the entire graph is below the x-axis, because there are no real zeros.

If the y-intercept is odd, then the constant term, c, in ax^2 + bx + c, must be a negative, odd integer.

Suppose we say that the vertex of a particular parabola that is described by the above is (-2, -1) and that the y-intercept is -3.  (Note:  this is strictly an example.)  Then the vertex equation of this parabola is obtained from the general vertex equation of a parabola,

y = a(x - h)^2 + k.  Here h = -2 and k = -1, and so the particular parabola is

y = -a(x + 2)^2 - 1, where a is a constant and -a is negative.

In general form, this would be y = -a(x^2 + 4x + 4) - 1, or

                                                   y = -ax^2 - 4ax - 4a -1

and the constant terem (-4a -1) must be an odd negative integer

This is only one of an infinite number of possible equations for the parabola described above.
