Answer:

9.3 simplified should be 3  if this isn't the answer then I don't know what is anymore because I just wasted my time if its wrong ;-;

Step-by-step explanation:

also I cant put the explanation sorry it says it has a link or inappropriate words in it when it doesn't.

9.3 divided by 3 is 3 so sense that isn't a fraction or anything i guess 3 is the answer in not to sure-

Answer:

x = 125 degrees

Step-by-step explanation:

ok so the 2 lines are parallel and there is a line through them

i see the opposite angle to x equals 125 degrees

they are the same so...

x = 125 degrees

I'm confused with that too, have you researched your answer?

Answer:

15, 17, 19

Step-by-step explanation:

let the first odd number be n then the next 2 are n + 2 and n + 4 , then

n + n + 2 + n + 4 = 51

3n + 6 = 51 ( subtract 6 from both sides )

3n = 45 ( divide both sides by 3 )

n = 15

Then

n + 2 = 17 and n + 4 = 19

The 3 consecutive odd numbers are 15, 17, 19

Answer:

25%

Step-by-step explanation:

MP= 40

SP= 50

Change(increase)  = 10

Change (increase) precentage =  10 / 40  x 100 = 25%

I hope im right!!

Answer:

25 percent

Step-by-step explanation:

£40 is the old price and £50 is the new price. In this case we have a positive change (increase) of 25 percent because the new value is greater than the old price.

Answer:

2.14% error

Step-by-step explanation:

Use the percent error formula:

| (observed - expected) / expected | x 100

Plug in the observed and expected values:

| (observed - expected) / expected | x 100

| (5.5 - 5.62) / 5.62 | x 100

Calculate:

= 2.14% error

So, the percent error of Jocelyn's estimate is 2.14%

Answer:

k=−0.8

Step-by-step explanation:

Start with the equation: 0.2(3k+1)=-0.4-(-0.2-0.1K)

Use distributive property on each side of the equation. For the left side, distribute 0.2 into 3k and 1, and for the right side, distribute -1 into -0.2 and -0.1k. (We use a -1 because the negative sign on the outside of the parenthesis is equivalent to -1)

(0.2)(3k) + (0.2)(1) = 0.6k + 0.2

(-1)(-0.2) + (-1)(-0.1k) = 0.2 + 0.1k

New equation: 0.6k + 0.2 = -0.4 + 0.2 + 0.1k

Now we can combine like terms on the right side. (-0.4 and 0.2)

0.6k + 0.2 = 0.1k - 0.2

Now to get rid of k on one side, we can subtract 0.1k from the right side.

(0.6k - 0.1k) + 0.2 = (0.1k - 0.1k) - 0.2

0.5k + 0.2 = -0.2

Now we need to get 0.5k by itself, so we'll subtract the 0.2 on both sides.

0.5k + (0.2 - 0.2) = (-0.2 - 0.2)

0.5k = -0.4

To get k by itself, we must divide both sides by 0.5.

(0.5k / 0.5) = (-0.4 / 0.5)

k = -0.8

Answer:

1. y = x2+2

2. g = (-3x+1)/x

Step-by-step explanation:

1. No explanation

2.

Let's solve for g.

gx=1−3x

Step 1: Divide both sides by x

gx /x  =  −(3x+1 )/x

g = (-3x+1)/x

Hope it helped!

Answer:

17/36

Step-by-step explanation:

We have to find a common denominator, so the first common denominator for 4 and 9 is 36. 9x4=36, so we multiply 2 by 4, which equals 8. 4x9-36, so we multiply the 1 by 9, and get 9. Then we add the numerators, 8 and 9, and get 17. So it's 17/36

Answer:

-40m = 59.2

Step-by-step explanation:

simplify

Answer:

-40m + 59.2

Step-by-step explanation:

Distribute

-40m + 59.2

If you're solving for m then set the equation equal to 0 and solve.

-40m + 59.2 = 0

-40m = -59.2

m = 37/25

Complete question :

Bernie and Chloe hiked the Tremont Trail to the end and back. Then they hiked the Wildflower trail to the end before stopping to eat lunch. Before Ricardo ate his lunch, he hiked 2 2/3 times as far as Bernie and Chloe. How far did he hike?

Required diagram is attached below

Answer:

25 miles

Step-by-step explanation:

Tremont Trail = 3 1/2 miles

Wildflower trail = 2 3/8 miles

Distance covered ; Tremont Trail and back : (3 1/2 * 2). = 7/2 * 2 = 14 /2 = 7 miles

Total distance covered by Bernie and Chloe before stopping for lunch /

(7 miles + 2 3/8 Miles) = 9 3/8 miles = 75/8 miles

Ricardo's distance = 2 2/3 * Bernie and Chloe's total distance

Ricardo's distance = 8/3 * 75/8 = 600 /24 = 25 miles

Answer:

x = -15

Step-by-step explanation:

Divide both sides by -2

x + 5 = -10

x = -15

Answer: x = -15

Step-by-step explanation:

-2(x + 5) = 20

-2x - 10 = 20

Add 10 to both sides

-2x = 30

Divide both sides by -2

x = -15

Answer:

16x-21=x+9

15x=30

Step-by-step explanation:

Answer:

£800

Step-by-step explanation:

when you recuce the price of something by 30%, it is 70% of the original (100% minus whatever percent reduction).

.7x=560 where x is the original price of the tv

560/.7=800

the original price of the tv is £800

Answer:

25. 50 percent of 50 is 25 divided by 2.

Step-by-step explanation:

step1:Our output value is .50.

step2:we represent the unknown value with x

step3: from step1 above,.50=100%

step4: similarly,x=50%

step5: This results in a pair of simple equation:

.50=100%(1)

x=50%(2)

step6:by dividing equation 1 by equation 2 and noting that both the RHS(right hand side)of both equations have the same unite(%);we have

.50. 100%

____. = ____

x. 50%

step7: again,the reciprocal of both sides gives

x. 50

___ =. ___

50. 100

°x=0.25

therefore,50%of.50 is 0.25
