Answer:

"Snack B and C are same ratio"

Step-by-step explanation:

We need to reduce each fraction and determine whether the ratios are same or not.

3/150 = 1/50

Checking A:

2/75 = 1/37.5

So, this is not equal to 1/50

Checking B:

4/200 = 1/50

THis is the same, so this is equal to 1/50

Checking C:

1/50

it is directly given, so this is equal as well

Hence, Snack B and C are same ratio.

A school pays $1,825 for 150 shirts. This includes the $25 flat-rate shipping cost.
yKpoI14uk [10]

Answer:

a)

We know that the total cost for the 150 shirts (plus a flat-rate of $25) is $1,825.

First, let's find how much costs each shirt.

First, the total cost of the shirts alone (neglecting the flat-rate) is:

$1,825 - $25 = $1,800

Then each shirt costs equal to the quotient of the cost and the number of shirts:

$1,800/150 = $12

Each shirt costs $12.

Then if you order T shirts, the total cost will be the flat-rate of $25 plus T times $12. The equation is:

C(T) = $25 + T*$12

b) C represents the cost

   T represents the number of shirts ordered.

c) The initial value is the constant value, in this case, is $25

The rate of change is the coefficient that multiplies the independent variable (T), in the equation the rate of change is $12.

Line GH contains points G(–2, 6) and H(5, –3). What is the slope of ?
alexgriva [62]

We will use the slope formula and fill it in accordingly.

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Our x2 is 5 and x1 is -2; our y2 is -3 and y1 is 6

m=\frac{-3-6}{5-(-2)}=\frac{-9}{7}.

The slope of your line is -9/7

7. If SK = 13x - 5, KY= 2x + 9, and SY = 36-x, find each value.
sweet [91]

Answer:

SY=34, SK=21 and KY=13

Step-by-step explanation:

we have that

SY=SK+KY

substitute the given values

(36-x)=(13x-5)+(2x+9)

solve for x

36-x=15x+4

15x+x=36-4

16x=32

x=2

<em>Find the value of SY</em>

SY=(36-x)=36-2=34

<em>Find the value of SK</em>

SK=(13x-5)=13(2)-5=21

<em>Find the value of KY</em>

KY=(2x+9)=2(2)+9=13
