if you do this and explain how to do it i will rait you 5 stars and give you a brainlyieist it has to be simplify 2(5+3x)+(x+10)

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

(5 + 3) x 3
(5 + 3) x 9
(5 + 3) x 3 is twice as much as (5 + 3) x 9
(5 + 3) x 9 is three times as much as (5 + 3) x 3
(5 + 3) x 9 is twice as much as (5 + 3) x 3
(5 + 3) x 3 is three times as much as (5 + 3) x 9

Answers

B because (5+3) x 3 is 24 and (5 + 3) x 9 is 72. So (5 + 3) x 9 is 3 times as much as (5+3) x 3.

Sam rode his bike 7 and one-half miles on Monday, 4 miles on Tuesday, and 6 and one-third miles on Wednesday. How many miles did he ride altogether?

A. 17 and two-fifths
B. 17 and three-fifths
C. 17 and one-sixth
D. 17 and five-sixths

Answers

Answer:

17 and 5/6

Step-by-step explanation:

7 1/2 mi. + 4 mi. + 6 1/3 mi.

= 7 1/2 mi. + 10 1/3 mi.

1/2 = 6/12

1/3 = 4/12

7 6/12 mi. + 10 4/12 mi.

= 17 10/12 mi.

= 17 5/6 mi.

Answer:

add 7 6 and 4 then add 1 half and 1 third of a mile ( a mile is about 5000 feet)

I haven't started learning variables, and stuff like that yet in class, and I wanna be ahead, so can somebody teach me?

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

Amil took $65.00 to go shopping, and he bought 2 pair of jeans for $27.00 each. How much change will he have? Choose the expression that is a correct translation of the problem.
(2 x 27) - 65
65 – (2 x 27)
65 – (2 + 27)
65 – 2 + 27

Answers

Answer:

B) 65 – (2 x 27)

Step-by-step explanation:

65 is you total, 2 is the amount of jeans and 27 is the individual price of the jeans.

Since you want to know how much is left over, you subtract how much you spent which would be, in this case, the jeans.

You bought 2 jeans, each for 27 dollars so you multiply the two to see how much for both jeans.

Subtract that from the total.

Hope this helps! (^-^)

Answer:

65-(2 x27)

Step-by-step explanation:

You already know that Amil has 65$ so that's the first part.

And then it tells you that he bought 2 pairs of jeans and the price.

So if u multiply how many jeans he got times the price that tells you how much it cost. So it cost 54$

Last but not least you subtract 54$(the price) from 65$(how much money he had) to get the amount of change left over.

Charles decides to use the method of proportions and similar
triangles to find the height of a lamppost. He measures the length of
the post's shadow and finds it is 10 feet long. Then he holds a 12-inch
ruler perpendicular to the ground and finds that it casts a 4-inch
shadow. How tall is the lamppost?
a. 2.5 ft c. 30 ft
b. 4.8 ft d. 120 ft

Answers

Answer:

C. 30 ft.

Step-by-step explanation:

10 = x

12 = 4

Divide by 4

1inch shadow = 3 inches height

1 inch of a shadow is 3 inches

10 feet is 120 inches

120 * 3

360 inches height = 30 ft

Consider Brainliest!

I think it might be A. Since sometimes shadows can come off longer than the actual object.

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
