Answer 1

Answer:

Answer:

$\boxed{ \bold{ \sf{ \: 1. \: \: \: \: \: 198}}}$

$\boxed{ \bold{ \sf{2. \: \: \: \: \: - 8}}}$

$\boxed{ \bold{ \sf{ 3. \: \: \: \: \: (64)/(343) }}}$

Step-by-step explanation:

1. Given, u = 20 , x = 4 , y = 7 , z = 10

$\sf{ (u)/(z) + x {y}^(2) }$

⇒ $\sf{ (20)/(10) + 4 * {7}^(2) }$

⇒ $\sf{ (20)/(10) + 4 * 49}$

⇒ $\sf{ (20)/(10) + 196}$

⇒ $\sf{ (20 + 196 * 10)/(10) }$

⇒ $\sf{ (20 + 1960)/(10) }$

⇒ $\sf{ (1980)/(10) }$

⇒ $\sf{198}$

2. $\sf{4( - 2)}$

Multiplying or dividing a positive integer by any negative integer gives a negative integer

= -8

3. $\sf{( (4)/(7) ) ^(3) }$

⇒ $\sf{( \frac{ {4}^(3) }{ {7}^(3) } })$

⇒ $\sf{ (4 * 4 * 4 )/(7 * 7 * 7)}$

⇒ $\sf{ (64)/(343) }$

Hope I helped!

Best regards! :D

Answer:

Answer:

$\Huge \boxed{\mathrm{18. \ \ \ 198}} \n\n\n \Huge \boxed{\mathrm{19. \ \ \ -8}} \n\n\n \Huge \boxed{\mathrm{20. \ \ \ (64)/(343) }}$

$\rule[225]{225}{2}$

Step-by-step explanation:

18.

$\displaystyle (u)/(z) +xy^2$

u = 20, x = 4, y = 7, and z = 10.

$\Rightarrow \displaystyle (20)/(10) +(4)(7)^2$

$\Rightarrow \displaystyle 2+(4)(49)$

$\Rightarrow 2+196$

$\Rightarrow 198$

19.

$4(-2)$

Rewriting.

$\Rightarrow -(4*2)$

Multiplying.

$\Rightarrow -8$

20.

$\displaystyle ( (4)/(7) )^3$

Distributing the cube sign to the numerator and the denominator.

$\Rightarrow \displaystyle (4^3 )/(7^3 )$

$\Rightarrow \displaystyle (64)/(343)$

$\rule[225]{225}{2}$

Julio's dad owns a restaurant. He bought 9 dozen potatoes to make french fries. He needs 7 potatoes for a large order of fries. How many large orders of fires will he be able to make?I multiplied 9x12=108
then divided 108/7
I got 15 with 3 left over. Is this right?

Answers

Answer:

yes, your math is correct

15 large orders of fries can be made

Step-by-step explanation:

There are two questions here: one in the question you're trying to answer, and one that you have asked about your math. Hence, there are two answers here.

9 dozen divided by 7 is ...

9·12/7 = 15 3/7

Julio's dad will be able to make 15 large orders of fries.

WHAT IS THE SLOPE OF THE LINE6X + 3Y = 18?
Can anyone actually help me work it out please

Answers

Answer:

$6x + 3y = 18 \n \n y = - 2x + 6 \n \n x = 3$

3y=6x=18 the equation must look like this y=mx+b where m is the slope in this case it is 2 and b is the y-intercept 18 hope it helps

What is the slope of the line that contains these points?x 15,17,19,21 y -10,2,14,26

Answers

Answer:

Step-by-step explanation:

The slope (m) can be found using the formula ...

m = (y2 -y1)/(x2 -x1)

Any pair of points will do. We can use the first two.

m = (2 -(-10))/(17 -15) = 12/2

m = 6

The slope of the line is 6.

Answer: 6
