Answer:

58.09 degrees C.

Step-by-step explanation:

T(m)=21+74*10^-0.03m

When m = 10 minutes:

T(10) = 21 + 74*10^(-0.03*10)

= 21 + 74*10^(-0.3)

= 58.0879

The sum of two numbers is 32 their difference is 10. Find the numbers.​
Rainbow [258]

The two numbers are: 21 and 11

Step-by-step explanation:

Let x and y be the two numbers.

x+y = 32

x-y = 10 Rewrite this as x = y+10 and substitute for x in the first equation.

(y+10) + y = 32 Simplify and solve for y.

2y+10 = 32 Subtract 10 from both sides.

2y = 22 Divide both sides by 2.

y = 11

x = y+10

x = 11+10

x = 21

weeeeeb [17]

Answer:

13) 25 and 17

14) cupcakes = $5

brownies = $3

Step-by-step explanation:

13)  you can set this up as equations

so x + y = 42

x-y = 8

solve simultaneously by subtracting from each other

2y = 34

y= 17

if y = 17

42 - 17 = 25 = x

14) set up as equations again

Ben    7c + 10b = 65

franklin   7c +7b = 56

subtract from eachother

3b = 9

b = $3

7c + 10(3) = 65

7c = 35

c = $5
