Expression A: 3(x + 2) Expression B: 3x + 6....... Which statement does not show that these expressions are equivalent? O A. Sub
Dovator [93]

Answer:

D. 3(x+2) can be rewritten as 3x + 6 using the distributive property

Step-by-step explanation:

Given

3(x + 2) = 3x + 6

Required

Explain

From the list of given options, option D answers the question.

This is because, the expression above involves distributive property and only option D correctly states that.

A distributive property is:

a*(b + c) = a*b + a * c

In this case:

a = 3  b = x   and c = 2

So:

a*(b + c) = a*b + a * c

Substitute values for a, b and c

3*(x + 2) = 3 * x + 3 * 2

3(x + 2) = 3x + 6

Haley got a 93% on her first math test and an 86% on her second test. What is her percent decrease from test 1 to test 2 to the
zhenek [66]

Haley’s Percentage Decrease from Test 1 to Test 2 to the nearest tenth is 7.5%

Nearest tenth can be defined as , Look at the hundredth number to round the decimal number to the nearest tenth. If it's more than 5, add one to the tenth value. Remove all the numbers that are present after the tenth place and leave the tenth place value alone if it is less than 5

Given that,

Haley’s Percent score in Test 1 = 93 %

Haley’s Percent score in Test 2 = 86%

Formula For calculating the Percentage Decrease is :

(Beginning Percentage – Final Percentage) / Beginning Percentage * 100

So, by using this formula we can calculate the percentage decrease of Haley’s Test

Percentage Decrease = (93% - 86%)/93% * 100

                 = 7.5%

Explain how to use the combine place value strategy to find 223 -119.
SashulF [63]
Combine place value strategy is useful if you try to subtract a number with bigger digits from a number with a smaller digit in the same place... such as now, where 3 is smaller than 9 in the ones place.

Then we can combine two place values: 23 and 19 and subtruct those. 23-19 is 4 (you can just count up from 19 to 23), so you know that the two will give  the result of 04, and then you can proceed to the left: 2-1=1.

so the final result will 104.
