Answer:
a=65
Step-by-step explanation:
Avem 375 pagini
Notam cu a numaruide pagini
In prima zi avem-a, poi a doua zi-a+5, a treia-a+10, apatra-a+
15 si a cincea zi avem-a+20
Le adunam si egalam cu 375
5a=50=375
5a=325
a=65
ANSWER
The multiplication, CA is defined, and its dimension is 3×2
EXPLANATION
Matrix A is a 2x3 matrix.
Matrix C is a 3×2 matrix.
The product of the two matrices , CA, is defined if and only if the inner product of their dimension are the same.
The inner products are the same.
Hence the matrix multiplication, CA is defined and its dimension is the outer products.
Answer:
62
Step-by-step explanation:
62+7000000= 7000062 however when you divide that by its constant of the root of the sqared denominator, you get 4. THENNNN you add 3 to planks constand to get 62.
Given:
Consider the expression is
To find:
The value of given expression using a suitable identity.
Solution:
We have,
Using the identity 
, we get
Therefore, the value of the given expression is .
Step 1 = 3.9 × 0.5 + 4 5/6 ÷ 3 3/7
Step 2 = 3.9 × 0.5 + 29/6 ÷ 24/7
Step 3 = 4.4 + 29/6 × 24/7
Step 4 = 4.4 + 29/1 × 4/7
Step 5 = 4.4 + 111/7
Step 6 =44/10 + 111/7
Step one : Write the problem
Step two : Change the mixed numbers to improper fractions
Step three : Multiplication and Division should be done first. Then simplify.
Step four : Change the division to multiplication and multiply.
Step 6 : Add the remaining fractions
Sorry i didn't know which one so i did the first one. Hope it helps you.
