Step-by-step explanation:

7. 4d + 6 =42

d = 9

8. -3y + 12 = -48

y = 20

9. k/2 + 9 = 30

k = 42

10. g/3 - 7 = 15

g = 66

11. z/5 + 3 = -35

z = -190

12. -9h - 15 = 93

h = -12

13. -3(n + 5) = 12

n = -9

14. -17 + b/8 = 13

b = -32

15. 7( c- 12 ) = -21

c = 9

Answer:

  112

Step-by-step explanation:

We can write the equation for the direct variation:

  y = kx

  34 = k(17)

  34/17 = k = 2

Then for the new x-value:

  y = 2(56) = 112

The value of y is 112 when x = 56.

__

Or, we can write the relation as a proportion:

  y/56 = 34/17

  y = 56(34/17) = 112

Answer:

2

Step-by-step explanation:

1+1 is equal to two. Imagine two objects, a green ball and a red ball. These one and one objects. Now you would want to but it inside a bag when you put it in the bag, someone asks you how many balls are inside the bag. Now count how many balls is in the bag which is 2.

Answer:

8 years

Step-by-step explanation:

Currently

Abebe → 12 years old

Aster → 2 years

With every passing year, each of them will be 1 year older hence the difference between their ages will remain constant.

Difference in ages

= 12 -2

= 10

Let the age of Aster be x years old when Abebe is twice her age.

Abebe → 2x years old

Aster → x years old

Difference in age

= 2x -x

= x

x= 10

Aster is 10 years old when Abebe is twice her age.

Number of years passed

= 10 -2

= 8

Thus, Abebe will be twice as old as her sister in 8 years.

Answer:

11) 7 ( Answer A)

12) (-2) ( Answer D)

Step-by-step explanation:

You can use y = m x + c to answer these questions.

In the equation y = m x + c,

m = slope

c = y - intercept

According to the question,

they have given the equation,

y = 7 x - 2

So, you can replace it with y = m x + c like this.

y = 7 x - 2

    ↑       ↑

    m      c

There fore,

slope = 7

y - intercept = ( - 2)

And now let's write the answers for the question.

11) 7 ( Answer A)

12) (-2) ( Answer D)

Hope this helps you :-)

[tex] \sf \: 4x - 11 [/tex]

Step-by-step explanation:

Given expression,

→ 4 + 5(2x - 3) - 6x

Let's simplify the expression,

→ 4 + 5(2x - 3) - 6x

→ 4 + 10x - 15 - 6x

→ (10x - 6x) + (4 - 15)

→ (4x) + (-11)

→ 4x - 11

Hence, the answer is 4x - 11.

Answer:

We can't see your answer choices, but it would be n + d = 368 and .05n + .10d = 28.40

Step-by-step explanation:

n+d=368 and 0.05n+0.1d=$28.40 is the system of equations below would be the best to use to find the number of nickels and dimes hunter has

Two or more expressions with an Equal sign is called as Equation.

Given that hunter has a jar of 368 nickels and dimes.

The total value of coins is $28.40.

We need to find the system of equations below would be the best to use to find the number of nickels and dimes hunter has

The total quantity of nickels and dimes is 328

n+d=368

The value of nickel is 0.05 dollars

The value of dime is 0.10 dollars

0.05n+0.1d=$28.40

Hence, n+d=368 and 0.05n+0.1d=$28.40 is the system of equations below would be the best to use to find the number of nickels and dimes hunter has
