Answer:

15 girls

Step-by-step explanation:

G : B : total

5 : 4 : 9

? :12: ?

No. of girls = (12x5)/4 = 15 girls

we put the ratio between girls and boys then we add the (total) or(sum) beside them in the same ratio then the summation of the ratio, like (5 +4 = 9) and then under the word "boys" we put the number given in the question which is (12) , now we need to know the number of girls in the class so we use the cross multiplication which i wrote at first.

by that, you can calculate no. of girls and no. of students in the whole class if you want.

Answer:

$a>6$

Step-by-step explanation:

1) Subtract 1 from both sides.

$a>7-1$

2) Simplify 7 - 1 to 6.

$a>6$

Therefor, the answer is a > 6.

Answer:

h = -t+20

After 8 hours the candle will be 12 inches

Step-by-step explanation:

We have 2 points (time, inches)

(3,17) and (5,15)

We can find the slope

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

= (15-17)/(5-3)

= -2/2

= -1

We can use point slope form

y-y1 = m(x-x1)

Replace y with h and x with t

h-17 = -1 (t-3)

Distribute

h-17 = -t+3

Add 17 to each side

h-17+17 = -t+3+17

h = -t+20

I didn't mean to post the answer and can't figure out how to take it down. Somebody report it so it does go down and the question can be later answered. Thank you

Answer:

1.) $slope=2$

2.) $slope=-3$

3.) $slope=\frac{1}{4}$

4.) $slope=-\frac{4}{5}$

Step-by-step explanation:

The unit rate is also known as slope. Slope is the change in the y values over the change in the x values:

$(x_{1},y_{1})\\\\(x_{2},y_{2})\\\\\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=slope$

However, with certain graphs, the slope can be found in a simpler manner.

You start at one point and move across the y-axis, then move along the x-axis until you reach another point on the same line.

Make sure you move on the y-axis first, then the x-axis. Record the slope as spaces moved in each $\frac{y}{x}$

When you move up, the number will be positive $(\frac{+y}{x})$ . If you move down, the number will be negative $(\frac{-y}{x})$ .
If you move to the right, the number will be positive $(\frac{y}{+x})$ . If you move to the left, the number will be negative $(\frac{y}{-x})$ .
