Monica walked every day for exercise at a rate of 1 kilometer every 20 minutes. At this rate, how many meters can Monica walk in 1 hour? EXPLAIN how you found your answer

Answers

3000 because 1 hour is 60 mins and that mean if monica walked for an hour than she would have walked 3 km and km is 3000m as 1km is 1m
3000 kilometers because there are three blocks of 20 minutes in an hour so multiply 1000 by 3

Will a 2 quart pitcher hold the entire recipe of citrus punch Givin at the right explain your reasoning

Answers

A 2 quart pitcher can not hold the entire recipe of citrus punch because it is too much to fit, it will overflow.

Final answer:

Whether a 2 quart pitcher can hold an entire citrus punch recipe depends on the volume of the punch recipe. If the volume of the punch is less than or equal to 2 quarts, then yes, otherwise, no.

Explanation:

To answer your question about whether a 2 quart pitcher can hold the entire recipe for citrus punch, we first need to know the volume of the punch recipe. Suppose the punch recipe yields 1.5 quarts, then yes, your 2 quart pitcher will hold the entire recipe because 1.5 quarts is less than the pitcher's volume of 2 quarts. If the punch recipe yields more than 2 quarts, like 3 quarts, then no, your pitcher won't be able to hold the entire recipe output because it's volume is less than the punch's volume.

Answer:

The correct answer is B. 10x - 12y

Step-by-step explanation:

To find this, we focus on just the like terms. So we break it down by the variable each time.

5x + 5x = 10x

-6y + -6y = -12y

z + -z = 0

So we put those answers all together to get 10 - 12y + 0 or just 10x - 12y

Deepak wrote out the steps to his solution of the equation StartFraction 5 Over 2 minus 3 x minus 5 plus 4 x equals negative StartFraction 7 Over 4 EndFraction – 3x – 5 + 4x = –. A table titled Deepak's Solution with 3 columns and 5 rows. The first row is, blank, Steps, Resulting equation. The second row has the entries, 1, Use the distributive property to simplify. StartFraction 5 Over 2 minus 5 plus 4 x minus 3 x equals negative StartFraction 7 Over 4 EndFraction. The third row has the entries, 2, Simplify by combining like terms, negative StartFraction 5 Over 2 plus x equals negative StartFraction 7 Over 4 EndFraction. The fourth row has the entries, 3, Use the addition property of equality, negative StartFraction 5 Over 2 EndFraction plus StartFraction 5 Over 2 EndFraction plus x equals negative StartFraction 7 Over 4 EndFraction plus StartFraction 10 Over 4 EndFraction. The fifty row has the entries, 4, Simplify by combining like terms, x equals StartFraction 3 Over 4 EndFraction. Which step has an incorrect instruction? Step 1 Step 2 Step 3 Step 4

Answers

Answer:

Step 1 instruction is incorrect.

Step-by-step explanation:

The given equation is (5)/(2)-3x-5+4x=-(7)/(4)

In step 1, Deepak rearranged the terms in order to simplify like terms together that is followed in step 2.

So, rearranging of the terms of an expression is commutative property and not distributive property.

Distributive property is generally applicable to multiplication and is given as:

a(b+c) = ab+ ac

Commutative property is given as:

a+b = b+ a.

Therefore, adding terms by changing their order is commutative property of addition and not distributive property.Step 1 instruction is wrong.
