Yes, algebra uses abstract symbols to represent concrete elements in the real world.

No, in an algebraic equation, the same variable cannot represent two different unknowns.

Yes, many great mathematicians were also philosophers.

No, An algebraic expression doesn't contains an equal sign, but an algebraic equation does.

No, if the expressions are in the same set. Yes, if they are not. (The same variable can represent two different unknowns in two different algebraic expressions.)

This weekend Vanessa made 4 times as many batches as last weekend. She made a total of 25 batches for the two weekends. Determin

MissTica

Answer: The number of batches made by Vanessa last weekend = 5

Number of batches made this weekend =20

Step-by-step explanation:

Let x be the number of batches made y Vanessa last weekend.

Given : This weekend Vanessa made 4 times as many batches as last weekend.

i.e. Number of batches made this weekend = 4x

She made a total of 25 batches for the two weekends.

i.e. $x+4x=25$

$\Rightarrow\ 5x=25$

Divide both sides by 5 , we get

$x=5$

i.e. number of batches made y Vanessa last weekend = 5

Number of batches made this weekend =20

Hence, the number of batches made by Vanessa last weekend = 5

Number of batches made this weekend =20

dolphi86 [110]

Answer:

your answer is 20mL or .020 Liters

Step-by-step explanation:

5 x 4 is 20, we do not add the 40 because in the problem it says 5mL for every 10 pounds, so, therefore, your answer is 20mL/.020 Liters

hope this helps have a great day ツ

The factor tree for 3,025 is shown. A factor tree starts with 3,025 at the top. 3,025 branches down to 5 on the left and 605 to

krek1111 [17]

Answer:

(5^2)(11^2)

Step-by-step explanation:

Taking all the factors in the left hand side of the factor tree, we have

5,5,11,11

5 twice

5^2=25

11 twice

11^2=121

The factor of 3,025=(5^2)(11^2)

Alternatively

3025÷5=605

605÷5=121

121÷11=11

11÷11=1

We have prime number 5 as divider twice and prime number 11 as a divider twice

Therefore,

5^2*11^2=3,025

Check

(5^2)(11^2)

=(25)(121)

=3,025
