b) How much rice is needed to make two and one half times the recipe???
Answer:
A) 7/8 cups B) 4 3/8 cups
Step-by-step explanation:
1 3/4 = 7/4
7/4 cut in half is 7/8
7/4 doubled is 7/2
7/2 = 28/8
28/8 + 7/8 = 35/8
35/8 = 4 3/8
Answer:
a) 7/8 cupsb) 4 3/8 cupsStep-by-step explanation:
Given
Full recipe = 1 3/4 cups of rice

Natalie and her sister opened savings accounts at the same time. Natalie deposited $100 and will deposit $10 each month. Her sister deposited $25 and will deposit $25 each month. When will Natalie have less money in her account than her sister?
Answer:
5
Step-by-step explanation:
Natalie
100 + 10x
Her sister
25 + 25x
Where
x = number of months
Equate Natalie and her sisters equation
100 + 10x < 25 + 25x
100 - 25 < 25x - 10x
75 < 15x
Divide both sides by 15
x < 75 / 15
x < 5

Sofia wants to rent an apartment. She visits Apartment A which charges $100 for a one-time deposit and $400 per month for rent. She also visits Apartment B which charges $500 for a deposit, but only charges $350 per month in rent. Write and solve an inequality that shows how many months it would take for the total paid to be less for Apartment B.
Credit To: "lublana" On Brainly For This Answer
Answer:
Given that one time charge of appartment "a" = $100
Given that monthly rent of appartment "a" = $400
say the number of months = x
then total cost of the rent for apartment "a" = 100+400x
Given that one time charge of appartment "b" = $500
Given that monthly rent of appartment "b" = $350
then total cost of the rent for apartment "b" = 500+350x
Now we have to make an inequality so that number of months it would take for the total paid to be less for apartment b.
that means 100+400x is less than 500+350x
Hence required inequality is 100+400x<500+350x.
Now we have to solve this inequality.
400x-350x<500-100
50x<400
divide both side by 50
x<8
hence final answer is number of months should be less than 8.

What is the difference between Glasgow and Copenhagen. (Glasgow= -7.8 Copenhagen=-3.8)
Answer:
Step-by-step explanation:
The difference of the two values is 4 as calculated by subtraction.
An arithmetic operation called subtraction is the process of deleting or removing items from a collection. The negative symbol (-) denotes subtraction.
Subtraction can mean eliminating or lowering physical and abstract quantities utilizing a variety of things, such as fractions, matrices, vectors, irrational numbers, decimals, functions, and however negative integers. it is typically linked with natural numbers in mathematics.There are several significant patterns in subtraction. It is anticommutative, which means that altering the sequence alters the answer's sign. Additionally, it is not associative, which means that when subtracting more than two numbers, the method used matters. 0 is the additive identity, hence subtracting it has no effect on a number. In relation to related operations like addition and multiplication, subtraction also abides by predictable principles.The given values for Glasgow and Copenhagen are given as -7.8 and -3.8 .
Therefore difference = -3.8 - (-7.8) = -3.8 +7.8 = 4
