Can someone help me 7 + 2h = 3 + 4h

Mathematics

STALIN [3.7K]3 years ago
7 0

h = 2

7 + 2h = 3 + 4h

You must isolate the variable to solve using the order of operations, or PEMDAS.

4 = 2h

Subtract 3 from both sides of the equation, and subtract 2h from both sides of the equation.

\frac{4}{2}  = h

Divide both sides of the equation by 2.

h = 2

Ashley starts with 45 comics. 

So in the first box: 
x  = 0, y = 45

Each month, she adds 5 comic books to her collection

x (+1), y (+5) (for each month).

First month. 

x = 0
y = 45

Second month

x = 1
y = 45 (+5) = 50

Third month

x = 2
y = 50 (+5) = 55

etc.

B) is your best choice, as for every month add (+1), the comic books increase by 5 respectively.

A dozen eggs cosy $1.32 at the grocery store .how much profit would a restaurant make if the sold 1 scramble egg for 99 cent
tatuchka [14]
What we know: A dozen costs 1.32; there are 12 in a dozen.
What we need to know: How much a restaurant makes selling 1 egg at 0.99.
First, find the value of one egg; you can do that by dividing the total cost (1.32) by the amount (12):
1.32 / 12 = 0.11    <--    The cost per egg is 11 cents. To find the profit of the restaurant, just subtract the cost from the price they sell it for:
0.99 - 0.11 = 0.88    <--    The profit the restaurant makes per egg is 88 cents.

Hope this helps.
