Answer 1

Answer:

Option A

Step-by-step explanation:

[tex]D=3ef^2\\[/tex]

we need to make e the subject of the formula so here goes,

On the right side 3 is being multiplied by ef^2 so when it moves to the left side it will divide

[tex]\frac{D}{3}=ef^2[/tex]

now f^2 is also being multiplied by e on the right side so when it moves to the left side it will divide

[tex]\frac{D}{3f^2}=e\\\\[/tex]

Answer:

CD = 7

Step-by-step explanation:

Given that the triangles are congruent, then corresponding sides are congruent, that is

CD = AB , substitute values

3y + 1 = 15 - 4y ( add 4y to both sides )

7y + 1 = 15 ( subtract 1 from both sides )

7y = 14 ( divide both sides by 7 )

y = 2

Thus

CD = 3y + 1 = 3(2) + 1 = 6 + 1 = 7

A group of friends went fishing. They each caught 20 fish but not all of them were keepers. Which person was able to keep 3/5 of the fish that he or she caught?

Answers

Answer:

Those who were able to keep 12 fishes

Step-by-step explanation:

Given

Total = 20 (each)

Required

Which was able to keep 3/5

First, we need to calculate 3/5 of the total number of fishes

Fish = 3/5 * 20

Fish = (3 * 20)/5

Fish = 60/5

Fish = 12

From the calculation above, only those who keep 12 of the 20 fishes were able to keep 3/5 of their fishes

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

6x - 5y = 15

x = y + 3

Step 2: Solve for y

Substitution

Substitute in x:                               6(y + 3) - 5y = 15Distribute 6:                                   6y + 18 - 5y = 15Combine like terms:                      y + 18 = 15Isolate y:                                         y = -3

Step 3: Solve for x

Define original equation:                    x = y + 3Substitute in y:                                     x = -3 + 3Add:                                                      x = 0
