Ellen bought new fish for her home aquarium. She bought 4 Turquoise Guppies and 3 Sunburst Tetra GLO Fish and spent a total of $41.73. Danielle bought 3 Turquoise Guppies and 5 Sunburst Tetra GLO Fish for a total of $56.02. How much was one Turquoise Guppy.

Answers

Answer 1

Answer: Ellen: 4t + 3s = 41.73

Danielle: 3t + 5s = 56.02

t = $3.69 each

Step-by-step explanation:

with 4t + 3s = 41.73 and 3t + 5s = 56.02

you need yo eliminate s to get t so multiply 3t + 5s = 56.02 by -3/5 to get

-9/5t - 3s = -33.612 then add 4t + 3t = 41.73 to get

11/5t = 8.118 then divide 8.118 by 11/5 to get

t = 3.69

Answer:

37

Step-by-step explanation:

20 + 13 = 33

so 70 - 33 = 37 so the answer is 37

Answer+explanation

so subtract the diffference of 20 and 13 from 70

so first we find the difference and then subtract that from 70

use parenthases so

difference of 20 and 13 is equal to (20-13)

subtract that from 70

70-(20-13)

so you would do the pemdas and get 7 for the inside parethasees then do

70-7=63

What is the value of c in the following equation: 29.4 + c = 62

B. 33
C. 32.4
D. 32.6

Answers

Answer:

D) 32.6

Step-by-step explanation:

This question is asked to find the value of "c", a variable.

We can rewrite the equation like this: 62 = 29.4 + c.

So, something + 29.4 = 62.

62 - 29.4 = 32.6.

3^3 + 6*3+ 5
27 + 6*3 + 5
27+ 18 + 5
The answer is 50

Answer:

50

Step-by-step explanation:

If x=3 then x^3 would be 3 with the exponent of 3. It would look like 3x3x3=27

6x would be 6 times 3 which is 18.

Then you have just an extra 5.

Then add them all together. 27+18+5=50.

Therefore, your answer is 50.

Answers

Answer:

y = 0,4x -1 or y = 2/5 x -1

Step-by-step explanation:

you can use the slope formula

m = y2-y1 / x2-x1

m = -1 - (-3) / 0 - (-5) = 2/5

Answer:

y = 2/5x - 1

Step-by-step explanation:

Points on the graph: ( -5, -3) and (0, -1)

Slope:

m=(y2-y1)/(x2-x1)

m=(-1+3)/(0+5)

m = 2/5

Slope-intercept:

y - y1 = m(x - x1)

y + 3 = 2/5(x + 5)

y + 3 = 2/5x + 2

y = 2/5x - 1

Write the equation of the line in slope-intercept form using y=mx+b​

Answers

answer:

y=1x-50

step-by-step explanation:

y=mx+b

m=slope

b=y-intercept

x=unknown variable

to find the slope i used rise/run

my rise was 3 and my run was also 3

3÷3=1

the slope is going to the right making it positive

the y-intercept is -50 because that is where the line hits the y-axis
