1. A scientist is growing cell cultures and examining the effects of various substances on them as part of his research. The cul

ture in one petri dish increases according to the expression +47 + 4 for timet in minutes. Another increases according to 12 + 2t+4. He needs to feed all the cells equally, so he needs to know the expression for the total number of cells in both dishes because the food is proportional to the total number of cells. Find the expression.​

Thepotemich [5.8K]

Answer:

The two linear equation

x + y = 19.... Equation 1

0.55x + 0.75y = 12.65... Equation 2

Nedra purchased

9 Apples and 11 Oranges

Step-by-step explanation:

Nedra purchased apples and oranges at the grocery store. which two linear equations can be used to find the number of apples and oranges?

Let the number of apples be represented by x

The number of oranges by represented by y.

Hence,

Apples are $0.55 each and oranges are $0.75 each. If she spent a total of $12.65 for 19 pieces of fruit,

Hence:

x + y = 19..... Equation 1

x = 19 - y

$0.55 × x + $0.75 × y = $12.65

0.55x + 0.75y = 12.65.....Equation 2

Hence: we substitute 19 - y for x in Equation 2

0.55(19 - y) + 0.75y = 12.65

10.45 - 0.55y + 0.75y = 12.65

-0.55y+ 0.75y = 12.65 - 10.45

0.20y = 2.2

y = 2.2/0.20

y = 11 oranges

x = 19 - y

x = 19 - 11

x = 8 Apples
