ANSWER

$T = \frac{3W}{S}$

EXPLANATION

The given formula is

$W = \frac{1}{3} TS$

We want to solve for T in the given formula.

We multiply through by 3 first to get,

$3 \times W =3 \times \frac{1}{3} TS$

We simplify to get,

$3W = TS$

We now divide both sides by S to get,

$\frac{3W}{S} = \frac{ TS}{S}$

We simplify to obtain:

$\frac{3W}{S} = T$

$T = \frac{3W}{S}$

Emily is entering a bicycle race for charity. Her mother pledged $0.40 for every 0.25 mile she biked. If Emily bikes 15 miles, h

Stolb23 [73]

Answer:

Her mother will donate $24

Step-by-step explanation:

In order to find this, first find the unit rate. To do so, divide the amount by the number of miles it takes to get that amount.

$0.40/0.25 miles = $1.60 per mile

Now we multiply that by the total number of miles.

$1.60 per mile * 15 miles = $24

An algebraic expression of the form a + bx has the value of 15 when x = 2 and the value of 3 when x = 5. Calculate a + b.

Ainat [17]

Answer:

The value of the expression (a +b) = 19

Step-by-step explanation:

The given expression is a + bx.

Case - I when x = 2, (a + bx) = 15

Putting the value of x , we get: a + 2b = 15

or, a = 15 - 2b ...... (1)

CAse II- when x = 5, (a + bx) = 3

Putting the value of x, we get a + 5b = 3

or a = 3 - 5b ....... (2)

Comparing (1) and (2)

15 - 2b = 3 - 5b

or, 5b - 2b = 3 - 15

or, 3b = - 12 ⇒ b = -4

if b = -4, then a = 3 - 5b = 3 + 20 = 23

Hence, a = 23, b= -4

So, the value of (a +b) = 23 - 4 = 19

Answer:

$\huge\boxed{\sf 37 }$

Step-by-step explanation:

Highest weight = 116 g

Lowest weight = 79 g

<h3><u>Range:</u></h3><h3>= Highest weight - lowest weight </h3>

= 116 g - 79 g

= 37
