54/3=18

54+18=72

Answer:

B

Step-by-step explanation:

0.25 = 1/4 = 5/20

0.35 = 35/100 = 7/20

5/20 + 7/20 = 12/20 = 6/10 = 3/5

Answer:

Step-by-step explanation:

so first you would do 0.25+0.35= 0.6

now put 0.6 into a fraction= 6/10 because 6 is in the 10th place then simplify 6/10=3/5 which to find that you divide each side by 2

Hope This Helped!

In this case, we need to substitute n with 10.

So, it is like this: f(10) = 3(10) + 4

f(10) = 3(10) + 4

f(10) = 30 + 4

f(10) = 34

Answer:

0. 42

Step-by-step explanation:

any number greater than 0 is significant if it's exactly 0 or less than 0 is not significant. since it's two significant figures you count the first two numbers greater than 0 which is 0.41 and we have 8 will is greater than 5 which will be rounded to 1 then rounded to 0.41 which makes it 0.42

Answer:

I'm sure you mean miles, but the car will travel 135 mites.

Step-by-step explanation:

(180/4)3 = 135 miles. The car will be traveling at 45 miles per hour since 180 miles divided by four hours is 45, then you can multiply that by three to get the distance the car will travel in the next three hours. A function that models this equation is f(x)=45x.

Check batteries=20

Battreies do not have charge=14

Out of the next batteries that you check=70

Expect to not have charge=30

Answer is 30.

Step-by-step explanation:

Number of batteries do not have charge from 20 batteries is 49 batteries

What information do we have?

Number of batteries do not have charge from 20 batteries = 14 batteries

Using ration of total batteries to do not have charge batteries

Number of batteries do not have charge from 70 batteries = 70[14/20]

Number of batteries do not have charge from 70 batteries = 7[7]

Number of batteries do not have charge from 20 batteries = 49 batteries

Answer:

8 teams each team will have 4 girls and 4 boys

Step-by-step explanation:

We use GCD to solve this

the GCD of 32 and 24 = 8

8 is the greatest number of teams.

each team must have equal number of boys and girls so divided by two

8/2 = 4

4 girls and 4 boys

I have attached how to do GCD.

Answer:

a) x = -2/3    y = -26/3 or -8 2/3

b) x = 12      y = 5

Step-by-step explanation:

a) since both equations begin with 'y =' you can set them equal to each other

4x - 6 = x - 8

3x = -2

x = -2/3

sub x value to find y:

y = 4(-2/3) - 6

   = -8/3 + (-18/3)

   = -26/3  

Step-by-step explanation:

ok so its basically like addition the top + the bottom.

3x + 3y = 12

6x + 11y = 14

9x + 15y = 26

now u wat to cancel out

9x + 15y = 26

9                

15y = 26     y = 1.7

9x = 26      x = 2.8

i think this is right i hopw this helps

Answer:

Bench costs $325

Step-by-step explanation:

Try setting up an equation

x = cost of garden table

y = cost of bench

equation 1: x + y = 585

We also know that the table costs 65 dollars less than the bench.

cost of garden table = bench - 65

or

equation 2: x = y - 65

Now just substitute equation 2 into equation 1

(y-65) + y = 585

and solve for y

2y-65 = 585

2y = 585 + 65 = 650

y = 325 = cost of bench

Answer and Step-by-step explanation:

You're told to find the ordered pair of point E.

E is found on the y-axis.

If you count upwards 8 units, you will see that point E is there.

So, Point E is at the coordinate (0, 8), where 0 represents 0 units on the x axis, and 8 represents 8 units up on the y axis.
