98x-5a(65x+2)-9(8x-7)

Answers

Answer:

6298x - 5a

Step-by-step explanation:

98x x 65x = 6370x

9 x 8x = 72x

6270x - 72x = 6298x

(all we have left now is the 5a)

6298x - 5a

What is the value of x?
3(-9 - 4x) - 4= 8x - 9(x + 12)

Answers

Answer:

x=7

Step-by-step explanation:

uhhh yes

Answer:

x=7

Step-by-step explanation:

3(-9 - 4x) - 4= 8x - 9(x + 12)

distribute

-27-12x-4=8x-9x-108

combine like terms

-31-12x=-x-108

add x to both sides

-31-12x+x-108

add 31 to both sides

-12x+x=-108+31

combine like terms

-11x=-77

divide both sides by -11

x=7

What is the perimeter of the figure on the coordinate plane below?

Answers

Answer:

26 units

Step-by-step explanation:

im not sure if this will help but i counted the spaces and added the halves

The perimeter of the given figure on the coordinate plane is 56 units.

What is perimeter?

A perimeter is the closed path that encompasses surrounds, or outlines either a two dimensional shape or a one-dimensional length.

Now from given figure, the following length of the sides is given,

9 units

4 units

8 units

11 units

3 units

2 units

15 units

Now since we know that,

Perimeter = Sum of lengths of all the sides

⇒ Perimeter = 9+4+4+8+11+3+2+15

⇒ Perimeter = 56 units

Thus, the perimeter of the given figure on the coordinate plane is 56 units.

Finding the slope:
Identify the slope on the graph below.

Answers

3/2 is the slope of the graph

Answer:

[tex]\frac32[/tex]

Step-by-step explanation:

Hello!

Slope can be calculated by [tex]\frac{Rise}{Run}[/tex].

The Rise of the graph is how much the graph changes in y between two points.The Run of the graph is how much the graph changes in x between two points.

I'll pick points (0,-2) and (2,1) on the graph.

You can see that the difference in y (-2 and 1) is 3 units.

The difference in x (0 and 2) is 2 units.

Put it into the format and you get a slope of [tex]\frac32[/tex].

Hi there! Let's start off with PEMDAS. It would appear that there are no parentheses or exponents, so let's get to that | Absolute Value |. -4 + 0 is -4, but because it's an absolute value, it'll become 4. The problem should read as 6/2*4. Let's move on to Multiplication/Division. 6/2 is 3, and multiplying 3 by 4 is 12.

Danielle is making protein balls. She uses 1 1/2 cups of protein powder, 2 1/4 cups of peanut butter, and 2/3 cup of honey. Which equation represents the total number of cups of ingredients Danielle uses?

Answers

Answer:

4 (5/12). four and five-twelfths

Step-by-step explanation:

1/2 is the same as 2/4, so: 1 1/2 = 1 2/4

1 2/4 + 2 1/4 = 3 3/4

3/4 and 2/3 have a LCM or least common multiple of 12

4 x 3 = 12 and 3 x 4 =12; but whatever you do to the bottom you have to do to the top (3/4) turns into (9/12) and (2/3) turns into (8/12)

9/12 + 8/12 = 17/12 or 1 5/12 as a mixed number

3 + 1 5/12 = 4 5/12

The answer is 4 5/12

A surfboard was originally priced at $75 but went on sale for 60% off. If Quincy bought the surfboard and paid 10% sales tax, how much did he pay in total?

Answers

Answer:

$49.5

Step-by-step explanation:

60% of 75$ = 45$

60/100 x 75/100 = 4500

4500/100 = 45

10% sales tax on 45$ = 49.50$

10/100 x 45/100 = 450

450/100 = 4.5

4.5 + 45 = $49.5

David is running a 500 m sprint. so far he has run 300 m. what fraction of the spirit does he have left?
?
__
?
what percent?________%

Answers

40 percent is left to run

Answer:

200/500=2/5

40%

Step-by-step explanation:

If the total distance of the sprint is 500m and he's already run 300m, so subtract 500-300 which equals 200.

Then put it in fraction form 500 being the total distance needing to be traveled in all will be your denominator and 200 being the distance left to be traveled will be your numerator. 200/500

Then simplify=200/500 divided by 100/100 equals 2/5.

Then to get it to a percentage divide 2 by 5 which equals .40

Then convert to a percentage 40%
