7 0

Answer:

7

Step-by-step explanation:

The probability of choosing a blue marble is 7/8, or 49/56, which means that out of 56 marbles, 49 are blue. 56-49=7, so there are 7 red marbles. Hope this helps! :)

What is an equation of the line that passes through the points of (0,-4) and (-4,6)
dusya [7]

Answer:

y = -5/2x - 4

Step-by-step explanation:

(0,-4) and (-4,6)

Slope:

m=(y2-y1)/(x2-x1)

m=(6+4)/(-4-0)

m=10/-4

m= -5/2

Slope-intercept:

y - y1 = m(x - x1)

y + 4 = -5/2(x - 0)

y + 4 = -5/2x

y = -5/2x - 4

a shipping company charged $15 to ship a package and 5% to ensure the package what was total cost to ship this
postnew [5]

Answer:

15.75

Step-by-step explanation:

So we know 5% is 1/20 out of 100 (20x5=100) so then we need to set up the equation to find how much 5% of 15 is. Which is .75 cents. So we then add the 75 cents to the already $15 shipping fee to get an answer of 15 dollars and seventy five cents.

If 2/3 = x/y, then which of the following must be true?
Kazeer [188]

Correct option is third \frac{2+3}{3}=\frac{x+y}{y}

<h3><u>Solution:</u></h3>

Given that:

\frac{2}{3}=\frac{x}{y}

Need to check which of the expression from given four expressions will be true.

Let's first try to eliminate wrong options.

If we observe carefully, we can say that option 2 that is \frac{3}{2}=\frac{x}{y} is not correct as \frac{x}{y} must be equal to \frac{2}{3} and not \frac{3}{2}

Lets now modify given expression that is:

\frac{2}{3}=\frac{x}{y}

On adding 1 to both sides we get

\frac{2}{3}+1=\frac{x}{y}+1

=>\frac{2+3}{3}=\frac{x+y}{y} \text { which is same as third option. }

Hence correct option is third one that is \frac{2+3}{3}=\frac{x+y}{y}
