MAVERICK [17]3 years ago
4 0

Answer:

B & C

Step-by-step explanation:

Okay I don't know much you need explained so I'm gonna explain pretty much everything. Starting off, you need to follow the PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. So when solving you have to do it in this order.

A-(5)(0.6)*7=21

B-(4/5)(15)+8=(0.8)(15)+8=20

C-4(8+2)/2=4(10)/2=40/2=20

D-14+4(2+3)=14+4(5)=14+20=34

If you need any clarification just lmk :)

34 is 40% of what number (a)6<br>(b)85<br>(c)60<br>(d)0.85
Elena-2011 [213]
<span>so, 6 is way to low to be a possibility.</span>

and 30 is half of 60 so 34 wouldn't  be 40 percent of 60.

and, it wouldn't be 0.85 that is less than 6 so they are both way too low 

from my understanding the answer would be 85  hope i helped. :)<span />

If you have 70 red blocks and 84 green blocks how many block stacks can you make with out having any left over?
devlian [24]

Answer:

14 stacks

Step-by-step explanation:

Given :

There are 70 red colored blocks

There are 84 green colored blocks

The ratio of green blocks to red blocks is $84/70 = 1.2$

Therefore, the ratio of g : b = 1.2 : 1

or                                  g : b = 6 : 5

Therefore, in order to calculate the number of stacks , we divide 84 by 6 and we get 14.

So we will get 14 block stacks to be made of 6 green blocks and 5 red blocks.

How do I graph this equation? y = -7/3x + 2
Molodets [167]
I can think of two ways to do it.

Way #1:

-- Pick a number.
   Write it in place of 'x', and calculate the value of 'y'.
   Call these 'x₁' and 'y₁'.

-- Pick another number.
   Write it in place of 'x', and calculate the value of 'y'.
   Call these 'x₂' and 'y₂'.

-- On your graph, mark little dots at the points (x₁, y₁) and (x₂, y₂).

-- With your ruler and pencil, draw a straight line between the two dots.
   Then extend it as far as you want to in each direction.

The line you drew is the graph of the equation.  
________________________________________

Way #2:

-- Looking at the equation, you realize that the slope of the graph is -7/3,
   and its slope is 2 .  Use this powerful information to draw the graph.

-- Mark a little dot on the y-axis, at the point where  y = 2 .

-- From that point, move your eyes 7 units to the right, then 3 units down,
   and mark a little dot where you land.

-- With your ruler and pencil, draw a straight line between the two dots.
   Then extend it as far as you want to in each direction.

The line you drew is the graph of the equation.
