1/5n=-7
Multiply both sides by 5 to get rid of the fraction.

One fifth of a number n is equal -7 as an equation would look like this:

1/5 n = -7          / * 5 (both sides)
n = -35

So if number n equals -35, then it's true that 1/5n equals -7.

It costs $36.76 for 3 tickets to visit the science center. It costs $51 for 4 tickets to visit the zoo. Which attraction will co
NeX [460]

Answer:

The zoo will cost more money for a group of 12 students to visit.

Step-by-step explanation:

First, you have to divide the costs by the amount of tickets to find out how much you would have to pay for one ticket.

Science Center: $36.76 ÷ 3 = $12.25

Zoo: $51 ÷ 4 = $12.75

Then, the cost for one ticket should be multiplied by 12, the group of students wanting to visit.

Science Center: $12.25 x 12 = $147.04

Zoo: $12.75 x 12 = $153

Comparing the prices, you will see that the zoo will cost $5.96 more dollars than the science center.

I will give the Brainliest answer! PLEASE HELP! The vertices of a triangle are located at the points A (1,1) , B (2,3), C (5,0).
NemiM [27]
1.
The first transformation, the translation 4 units down, can be described with the following symbols:

(x, y) → (x, y-4).

as the points are shifted 4 units vertically, down. Thus the x-coordinates of the points do not change.

A'(1, 1) → A"(1, 1-4)=A"(1, -3).
B'(2, 3) → B"(2, 3-4)=B"(2, -1).
C'(5, 0) → C"(5, 0-4)=C"(5, -4).

2.
The second transformation can be described with:

(x, y) → (x, -y). 

as a reflection with respect to the x-axis maps:

for example, (5, -7) to (5, 7), or (-3, -4) to (-3, 4)


thus, under this transformation A", B", C" are mapped to A', B' and C' as follows:

A"(1, -3)→A'(1, -(-3))=A'(1, 3)
B"(2, -1)→B'(2, -(-1))=B'(2, 1)
C"(5, -4)→C'(5, -(-4))=C'(5, 4)

Answer:

A'(1, 3),  B'(2, 1),   C'(5, 4)
