What is the correct answer please

Verizon [17]

Answer:

C

Step-by-step explanation:

$\frac{15y-10}{3x}$ = 6 ( multiply both sides by 3x to clear the fraction )

15y - 10 = 18x ( add 10 to both sides )

15y = 18x + 10 ( divide terms by 15 )

y = $\frac{18}{15}$ x + $\frac{10}{15}$ , that is

y = $\frac{6}{5}$ x + $\frac{2}{3}$ → C

O the photo slash picture

Evgesh-ka [11]

Answer:

The shortest walking route is through the diagonal AC: 102.89m

Step-by-step explanation:

One can go from A to C using 2 paths:

- ADC or ABC

- using diagonal AC and half of that inner circle.

We need to compute the length of each path.

1) ADC=AD+DC=80+50=130m

2) AC²=AD²+DC²=80²+50⁵=6400+2500= 8900m²

AC=sqrt(8900)=94.34m.

Note that the diagonal AC has a missing segment, whose length is the diameter of the inner circle. So the straight line has a length of: AC-d=94.34-15=79.34m.

Perimeter of half the circle=pi×r= 3.14×(15/2)= 3.14×7.5=23.55m

So, if one is using the diagonal to go from A to C, then he has to walk:

79.34+23.55=102.89m

Comparing the two routes: 130m vs 102.89m, we notice that the route using the diagonal AC is shorter.

HELP!!!!!!!!!!!!!!!!!!!!!!

Multiplying factors with exponents means you can add the exponents.

So $2^{4} \cdot 2^{-7} = 2^{4-7} = 2^{-3}$

A negative exponent becomes positive when you move it to the denominator, so:

$2^{-3} = \frac{1}{ 2^{3} }$

The Cooper family, consisting of 6 children and 2 adults, goes to the movies and pays a total of $86. The Griffen birthday party

Oksanka [162]

Answer: The cost of child's ticket = $10

The cost of adult ticket = $ 13

Step-by-step explanation:

Let x be the cost of a child ticket and y be the cost of an adult ticket.

Then According to the question, we have

$6x+2y=86..........................(1)\\\\10x+3y=139.......................(2)$

Multiply equation (1) by 3 and equation (2) by 2, then we have

$18x+6y=258.......................(1)\\\\20x+6y=278...........................(2)$

Subtract equation (1) from equation (2), we have

$2x=20\\\\\Rightarrow\ x=10$

Substitute the value of x in equation (1), we get

$60+2y=86\\\\\Rightarrow\ 2y=26\\\\\Rightarrow\ y=13$

Hence, the cost of child's ticket = $10

The cost of adult ticket = $ 13
