Answers

Answer:

(-(7-9))(z)-6z= 8(-6+2)

Simplify

-(-2)(z) -6z =8(-6+2)

Multiply 8*-6 and 8*2

2z -6z= -48+16

Combine like terms

2z+-6z =-32

-4z=-32

Divide both sides by -4

z=8

help. how do I solve this. it is an exterior triangle.

Answers

all triangle add up to 180

so 180-(96+48)

which is 36

so 36 is the missing interior angle

now all lines also equal 180

so 180-36=x

x=144

Someone buys 6 cakes for 8$ each he sells them for ten each then he got 8 more and selled them for 10$ how much money does he have left???

Answers

Answer: $28

Step-by-step explanation:

The person bought 6 cakes for $8 which reduces his money by:

= 6 * 8

= -$48

He then sells them for $10 each so the money made was:

= 10 * 6

= $60

He then buys 8 more for the same price which will reduce his money by:

= 8 * 8

= -$64

He sells these 8 for $10 so the money made was:

= 8 * 10

= $80

Total money left is therefore:

= 60 + 80 - 48 - 64

= $28

50 points to whoever is right and brainliest. The graph shows a proportional relationship. Which equation matches the graph?​

Answers

Answer:

B. y = 3x

Step-by-step explanation:

Use one of the points on the graph to find the equation.

Let's take the point (1,3)

We know the proportional relationship is:

y = kx, where k is the coefficient of proportionality

Substitute the values from the point and solve for k:

3 = 1*kk = 3

The function is:

y = 3x

Correct choice is B

Answer:

The graph is in a proportional relationship (given)

Therefore, it is in the form y=kx where k is a constant.......(i)

Now in the graph we can locate that when the value of x is 1, the value of y will be 3

Putting the value of x and y in equation (i), we get

3=1×k

k=3

Now, putting the value of k in equation (i), we get

The equation of the graph is y=3x.

★ B. y=3x is the right answer.

60% of 15 is what answer

Answers

The correct answer is 9. :)

Answer:9

Step-by-step explanation:

Think of it this way:

If 15=100%

then x= 60%

So what you do is you multply 60 times 15 and divide it by 100 to give you the answer of 9. To me this is the simplest way to do it, I believe it’s called butterfly multiplying. You cross multiply and then you divide.

Right answer will get brainlist.

Answer:

y = (2/3)x + 7

Step-by-step explanation:

Slope intercept form is y = mx +b

1) We start off with y =

2) m = slope. Since we know that the slope is 2/3 we can plug it in. y = 2/3x

3) b is y-intercept which = 7.

Put it all together: y = 2/3 x + 7

The answer is

y = 2/3x +7
