Answer:
22.5 grams of 10% cream is mixed with 37.5 grams of 2 % cream to prepare 60 grams of 5% cream.
Step-by-step explanation:
Let x grams of 10% cream is mixed with y grams of 2 % cream to prepare 60 grams of 5% cream.
So, x + y = 60 ............ (1) and
⇒ 10x + 2y = 300
⇒ 5x + y = 150 ............ (2)
Now, solving equations (1) and (2) we get,
4x = 150 - 60 = 90
⇒ x = 22.5 grams
So, y = 60 - x = 37.5 grams. (Answer)
Answer:-11/32
Step-by-step explanation:
-7/8 - (-17/32)
= -7/8 + 17/32
The highest common factor is 32
= (-7*4+17)/32
= (-28+17)/32
= -11/32
Answer:
a) He can find the answer in one way
b) We make use of Addition property of mathematics
c) Total number of blocks = 12 blocks
Step-by-step explanation:
a) He can find the answer in one way
b) We make used of addition property of mathematics
c) The total number of blocks he is having is calculated as:
Blue blocks + Pink blocks + Green blocks
Where
Blue blocks = 5
Pink blocks = 3
Green blocks = 4
Hence:
Total number of blocks = 5 + 3 + 4 = 12 block
Answer: 2535
Step-by-step explanation:
use order of operations (parenthesis, exponents, multiplication/division, addition/subtraction)
first ill handle the two innermost parenthesis
(4 + 3(2 - 8))
(4 + 3(-6))
(4 - 18)
-14
now lets move on to the next parenthesis
( 3 - 5^2(-14))
(3 - 25( - 14)
( 3 + 350)
353
now onto the last part of the problem
8^2 + 7 (353)
64 + 2471
2535 :))
