3,100

You add up what she is getting and than subtract how much she needs with what she has so far. And that’s the answer. So 2000+ 1500= 3500 than 6,600-3500

13) Ayla's lunch bill was $8.70 and Harley's was $10.30. The girls' uncle paid

Otrada [13]

Answer:

$2.85

Step-by-step explanation:

First, add the bill up ($8.70 + $10.30 = 19). So now you need to find what 15% of $19 is...To find the percentage of something you need to turn it into a decimal, 0. (whatever the percentage number is). So in this case, 19 times 0.15, which is a tip of $2.85.

You have $25 to spend on picking 21 pounds of three different types of apples in an orchard. The Empire apples cost $1.40 a

Semmy [17]

Answer:

5 pounds of the Empire apples, 14 pounds of the Red Delicious apples, and 2 pounds of the Golden Delicious apples.

Step-by-step explanation:

Let's call the Empire apples weight at E, the Red Delicious at R, and the Golden Delicious at G. We know that the total weight must be 21 pounds so:

R + E + G = 21 (<em>equation 1</em>)

The total amount of spent must be $25, and the price given is per pound, so the priced paid is the cost multiplied by the weight:

1.40*E + 1.10*R + 1.30*G = 25 (<em>equation 2</em>)

And the weight of the Red Delicious must be equal to twice of the combined weight of the others:

R = 2*(E + G)

E + G = R/2 (<em>equation 3</em>)

Let's substitute equation 3 in equation 1

R + R/2 = 21

(2R + R)/2 = 21

3R = 42

R = 14 pounds.

So, E + G = 7

G = 7 - E (<em>equation 4</em>)

Let's substitute the result of R and the equation 4 in the equation 2:

1.40*E + 1.10*14 + 1.30*(7 - E) = 25

1.40E + 15.40 + 9.10 - 1.30E = 25

0.10E = 25 - 24.50

0.10E = 0.50

E = 5 pounds

G = 7 - E

G = 7 - 5

G = 2 pounds.

The outside edges of the walkway form a rectangle whose length and width are proportional to the sides of the garden, increased

Allisa [31]

The length and the width of the outside edge of the garden will be ( 6x + 12 ) and ( 9x + 6 ) respectively.

<h3>What is the scale factor?</h3>

In mathematics, a scale factor is the proportion of related dimensions of an object to a description of that object.

Given that:-

The outside edges of the walkway form a rectangle whose length and width are proportional to the sides of the garden, increased by a scale factor of 3. the sides of the garden are (2x+4) and (3x+2)

The length and width of the outside edge will be:-

The sides are Dilated by factor 3 so the edges of the rectangle will be calculated as;-

Length = 3 ( 2x+4 ) = 6x + 12

Width = 3 ( 3x+2 ) = 9x + 6

Therefore the length and the width of the outside edge of the garden will be ( 6x + 12 ) and ( 9x + 6 ) respectively.

Anna11 [10]

Step-by-step explanation:

________________________________________________________________

$(1,000,000) + (3,00,000) + (60,000)+(2,000) + (700)+( 40)+8 \\ = 1300000 + 62000 + 740 + 8 \\= 1362000 + 748 \\= 1362748$

Solve for brainliest and all my points

inessss [21]

Answer:

b = 6 units

Step-by-step explanation:

Area = 1/2bh

8 = 1/2(b)(8/3)

divide both sides by 1/2

16 = b(8/3)

multiply both sides by 3

48 = 8b

divide both sides by 8

b = 6 units

For your boxes:

1/2 x b/1 x 8/3 = 8/1

b/1 x 8/3 = 16/1

8b/3 / 8 = 2/1

b/3 x 3 = 6
