2 + 7 = 4 + 1 (x ) − x 4
may give brainliest only IF your explain how you got your answer. And I will thank you and all that (15 points:))

Answers

Answer 1

9 = 4 + x - 4x minus 4
5 = x - 4x
5 = -3x divide by -3
-3/5 = x

Answer 2

To solve this we know that 2+7=9 so for 4+1(x)-x4 to equal 9 you would first multiply x and 4 to get 4x. Next you would subtract 1x-4x which equals -3x+4 . What you do to the right you do to the left so 9-4=5. Which you the have 5=(-3x) so you then divide the 3x by 3 which leaves you with x. So x = -5/3 .

Diana is painting statues. She has 7/8 of a liter of paint remaining. Each statue requires 1/20 of a liter of paint. How many statues can she paint?

Answers

Answer:

question is incomplete. A complete question is ----> Diana is painting statues. She has 7/8 of a liter of paint remaining. Each statue requires 1/16 of a liter of paint. find the number of statues.

each statue requires 1/16th of a liter of paint.

so, in a liter , 16th statues can be painted by Diana.

but A/C to question,

she has 7/8 of a liter of paint remaining.

so, we have to find how many statues she can paint in 7/8 litres.

so, number of statues = 7/8 × 16 = 14

Step-by-step explanation:

she can paint 10 statues! hope this helps! :)

Answers

Answer:

20+7x

Step-by-step explanation:

you'd multiply 2 by 5 and 2 by 3x which will give you 10+ 6x; Then add the others : 2(5+3x)+(x+10) would be 10+6x+x+10 so its 20+7x. .

Answer: 30+4x or 2(15+2x)

Step-by-step explanation:

So the way you would do this is actually kinda simple.

You question is 2(5+3x)+(x+10)

First you wanna add the common number together. So you would change you problem to

2(5+10)+(x+3x)

Now you want to start by solving 2(5+10)

The two on the outside means you multiply so you would do

2x5+2x10 you would get the answer 10+20=30

Now you’re equation is 30+(x+3x)

So now you need to do (x+3x) in this case we would make X=1

So you do 1+3(1) or 1+(3x1) And you get 4x

Now you have the answer 30+4x or to siplfy it you get 2(15+2x)

Hope this helps you xoxo

For part a I would say you can’t use that translation to change it back to the original triangle. I tried the rule out for myself

My coordinate was 3, 6 and applied the -7 -6 rule and got -4,0.

Then I used the rule that they have to translate it back which was -6 -7 and there’s no way it can be translated back to 3, 6

So the answer is no the rule can’t be used to translate it back

Answers

Answer:

Step-by-step explanation

its really simple u replace the letter with the value they have given u

t= 6

= 6x6-20-32u

u=1/4

=36-20-32x1/4

Hey, so in this case, the variable are t and u.
They gave you the numbers that each variable represents. Which are:
t=6 and u=1/4
So now what you need to do is, replace the variables with the numbers they represent in the equation. So it’s gonna be:
6(6)-20-32(1/4)
So now use PEMDAS to calculate. PEMDAS (parentheses - exponents - multiplication - decision - addition - subtraction)

So multiply 6 with 6, and then multiple 32 with 1/4.
36-20-8
Now subtract to get the answer.

Answer:
36-20-8= 8

The answer is 8
