Rewrite using the Associative Property, then evaluate. 10 x (3 x 14) & (12 + 21) + 34Rewrite using the Commutative Property, then evaluate. 23+12.4+7

Answers

Answer 1

Answer: 10 times (3*4)
You have to multiply 10 with both of the numbers in parenthesis
So, 10*3=30 and 10*4=40
30+40=70
Does this look right for the first one

How many solutions does the equation have? a+5=1/5(5a+25)

Answers

a + 5 = $(1)/(5)$ (5a + 25)

First, simplify $(1)/(5) (5a + 25)$ to $(5a+25)/(5)$ / Your problem should look like: $a + 5 = (5a+25)/(5)$
Second, multiply both sides by 5. / Your problem should look like: $5a + 25 = 5(a + 5)$
Third, expand to get rid of parenthesis. / Your problem should look like: $5a + 25 = 5a + 25$
Fourth, both sides are equal, resulting it having infinite solutions.

Answer: infinite solutions

7. Amber has $37 to spend. She bought a coffee for$1.75 and she wants to buy donuts that cost $1.50
each. What is the maximum number of donuts
Amber can buy with $37? Write an inequality to
represent this situation who's the
Inequality
A: 1.75c + 1.50d 5 37t Go to #9
B: (1.75 +1.50) 3 < 37 Go to 10
C: 1.75 +1.500 > 37 Go to #1
D: 1.75 + 1.50d < 37 Go to #12

pls give me the answer

Answers

Answer:

Step-by-step explanation:

1.75 ( would be the coffee) + 1.50d (donuts each but an unknown quantity)

total amount must be less than $37 dollars

Your answer would be 37.00 - 1.75 = 35.25 cents

35.25 / 1.50 = 23.5 donuts - you can not purchase a half of a donut so you can buy 1 coffee and 23 donuts for $36.25

What is 2 and 5/12-( -2 and 1/6) ?

Express the answer in simplest form.

Answers

Find the LCD, and modify the first fraction. the new equation is: 2 5/12 - (-2 2/12). since subtracting a negative is the same as adding, you add the second fraction: 2 5/12 + 2 2/12. add the fractions, and add the whole numbers. the answer is: **4 7/12**

Through: (3,5), slope = 5/3

Answers

the formula is : y = mx + b so m is the slope and b is the y-intercept and now you have : 5 = 5/3(3) + b so you need b so you can say :
5 = 5/3(3) + b ⇒ 5 = 5 + b ⇒ 5 - 5 = b so b =0 so in this question we dont have any y-intercept so the answer is : y = 5/3x
but an other formula is : ( y - 5 ) = 5/3 ( x - 3 )
but the standard form is gonna be : y - 5/3x = 0 or 3y - 5x = 0 :))
i hope this is helpful
have a nice day

Need help on question 9

Answers

Answer: Choice A) The figure and its image are similar, but not congruent, and the image has been translated 1 unit up.

The jump from (x,y) to (2x,2y) means we dilated by a scale factor of 2. The image is twice as large as its original. There is no way the two figures are congruent (the larger image has longer side lengths). Despite congruence not being preserved, the two figures are the same shape, so they are similar figures. After the dilation is done, the "+1" tacked onto the "2y" means we shifted every point up 1 unit.
