3x + 3y = 6

Answers

Answer:

Slope: -1, y-intercept: 2.

Step-by-step explanation:

3x + 3y = 6 in slope intercept form is y = -x + 2. Slope-intercept form is y = mx + b. As we know, m is slope and b is y-intercept. This means the slope is -1 and the y-intercept is 2.

What percentage of the shape is orange?
Write your answer using a percent sign (%).
(help!) almost done!! I will mark who ever awnser s first as brainliest!

Answers

Answer:

40%

Step-by-step explanation:

There are five pieces of a square.  Two of the five pieces are shaded in orange, since each piece is 20% and there are two shaded pieces, it is your best bet that your final answer is 40%.

Answer:

40%

Step-by-step explanation:

Since there are only two boxes filled, the fraction would be 2/5. Now, by applying that knowledge, you can see that the bow is filled 40% of the way with orange. An easy way to figue this out would be to divide 2 by 5 and get the decimal of .4 which as a percentage would be 40%. Hope this helped!

Step-by-step explanation:

just minus 100 out of the percentage

for example 20% is 100 - 20 = 80

80% is 120 - 40 is half of 80 so multiply by 2 and you get 120
40% is 60 - given
20% is 30 - 20 is half of forty so half of 60 is 30
10% is 15 - half of 20 is 10 so half of 30 is 15

The length of a rectangle is 5 inches more than three times the width.The perimeter is 64 inches. Find the length and width.

Answers

Answer:

L=25.25 in

W= 6.75in

Step-by-step explanation:

Step one

Given data

Let the width be x

W= x

and length

L= 3x+5

Perimeter= 64 in

Step two:

we want to find the dimension of the rectangle

We know that perimeter is

P= 2W+2L

64= 2*x+2*(3x+5)

64= 2x+6x+10

collect like terms

64-10=8x

54= 8x

divide both sides by 8

x= 54/8

x= 6.75in

We know that the length is

L= 3x+5

L= 3*6.75+5

L= 20.25+5

L=25.25 in

herlene has 5.05 in quarters and dimes. The number of quarters is one more than twice the number of dimes. Find the number she has of each kind.

Answers

Answer:

Herlene has 8 dimes and 17 quarters

Step-by-step explanation:

System of Equations

Let's call:

x = number of dimes Herlene has

y = number of quarters Herlene has

Since each dime has a value of $0.10 and each quarter has a value of $0.25, the total money Herlene has is 0.10x+0.25y.

We know this amount is $5.05, thus:

0.10x + 0.25y = 5.05        [1]

It's also given the number of quarters is one more than twice the number of dimes, i.e.:

y = 2x + 1        [2]

Substituting in [1]:

0.10x + 0.25(2x + 1) = 5.05

Operating:

0.10x + 0.5x + 0.25 = 5.05

0.6x = 5.05 - 0.25

0.6x = 4.8

x = 8

From [2]:

y = 2*8 + 1 = 17

y = 17

Herlene has 8 dimes and 17 quarters
