Answer:

Expression: 6w+$60 Money: $99

Step-by-step explanation:

So, let's find the ammount for 6 weeks

We know he can make $6 per week, so we ned to multiply 6*$6 to get your answer

So, 6 ( weeks ) * 6 ( dollars) = $36 for 6 weeks

Then, we ned to add the $60 he already has saved up, so $60+$39=$99

For the equation, We know that we need to multioply the number of weeks by 6, as shown by how we solved the last problem

So, 6*w=6w

Then we need to add $60

So, we get 6w+$60 for the expression

Answer:

96

Step-by-step explanation:

Answer:

First, we can write a fraction as a/b

Where a is the numerator, and b is the denominator.

A proper fraction is a fraction where the numerator is smaller than the denominator.

Using only the given numbers (only once per fraction), some examples of proper fractions are:

3/5

3/8

5/8

3/85

3/58

5/83

5/38

8/35

8/53

You can see that in all of them the denominator is larger than the numerator.

The improper fractions are those where the numerator is equal or larger than the denominator.

The 9 examples using the given numbers are:

5/3

8/5

8/3

35/8

38/5

53/8

58/3

83/5

85/3

Answer:

(x-3)² + (y+5)² = 16

Step-by-step explanation:

Radius will be half of diameter means that radius = r = 8/2 = 4.

With Center (h,k) the equation of circle is

(x-h)² + (y-k)² = r²

so by putting values answer will be

(x-3)² + (y+5)² = 4²

(x-3)² + (y+5)² = 16

Answer:

128

Step-by-step explanation:

You would multiply 79 by 1.62 to get the answer.

This would give you 127.98 which you would round up to 128.

Answer:

128

Step-by-step explanation:

Answer:

False

Step-by-step explanation:

1/2 - 5/8 - 7/9 = 7/9 - 5/8 - 1/2

Add 5/8 to both sides.

1/2 - 7/9 = 7/9 - 1/2

Factor -1 out of the right side.

1/2 - 7/9 = -1(-7/9 + 1/2)

1/2 - 7/9 = -1(1/2 - 7/9)

1/2 - 7/9 and 7/9 - 1/2 are opposites. Opposites are not equal unless they are both zero.

Answer: False

Answer: 2/3, 3/4, 5/8, 5/6

Step-by-step explanation:

First,

We must turn all of them into denominators that can be divided by 1/2.

2/3 = 4/6. 3    1/3 = 2/6  

Now we see which is greater.  

2/3 > 1/2.  

3/4 > 1/2.

2/6 < 1/2.

1/3 < 1/2.

3/8 < 1/2.

5/8 > 1/2.

1/4 < 1/2.

5/6 > 1/2.

So the answers are 2/3, 3/4, 5/8, 5/6.

Answer: 12250 Grams

Step-by-step explanation:

1 Kilogram = 1000 grams.

12 Kilograms x 1000 Grams = 12000 Grams.

1/4 = 0.25

0.25 Kilograms x 100 Grams = 250 Grams

12000 + 250 = 12250.

Answer: 12250 Grams.

Answer:

8.5

Step-by-step explanation:

Step-by-step explanation:

If it is an isosceles triangle, Option A is most suitable.

But if it's a scalene triangle, Option B,C and D would suffice.

Answer:

  [1]    x - 6y = 3

  [2]    x + 2y = 5

Graphic Representation of the Equations :

   -6y + x = 3        2y + x = 5  

Solve by Substitution :

// Solve equation [2] for the variable  x

 [2]    x = -2y + 5

// Plug this in for variable  x  in equation [1]

  [1]    (-2y+5) - 6y = 3

  [1]     - 8y = -2

// Solve equation [1] for the variable  y

  [1]    8y = 2

  [1]    y = 1/4

// By now we know this much :

   x = -2y+5

   y = 1/4

// Use the y  value to solve for  x

   x = -2(1/4)+5 = 9/2

Solution :

{x,y} = {9/2,1/4}

Answer:

33433.2

Step-by-step explanation:

504 - 300 = 204

204 + 800 = 1004

100 / 3 = 33.3

1004 x 33.3 = 33433.2

Answer:

the two numbers are 12 and -1.

Step-by-step explanation:

Let the large number be represented by x and the smaller number by y.

So that;

x = 8y + 20 .................. 1

x + y = 11 ................... 2

From equation 2,

x = 11 - y .......... 3

Substitute equation 3 into equation 1 to have,

11 - y = 8y + 20

11 - 20 = 8y + y

-9 = 9y

divide through by 9 to have,

y = -1

Substitute the value of y in equation 3,

x = 11 - (-1)

  = 11 + 1

  = 12

x = 12

x = 12, y = -1

The two numbers are 12 and -1.

Answer:

33.9

Step-by-step explanation:

cos rule:

a²=b²+c²-2xaxbxcosA

rearrange:

cosA=(b²+c²-a²)÷(2xaxb)

solve:

cosx=(8²+22²-16²)÷(2x8x22)

cosx=(64+484-256)÷352

cosx=292÷352

cosx=0.830

cos^-1(shift cos)=33.9

Answer:   Y=-7 X=-9

Step-by-step explanation:

Answer:

Yes, because y=5 will intersect the y axix (giving a horizontal line) and x =-3 will intersect the x axis (giving a vertical line). They will intersect at angle 90.

Step-by-step explanation:

Please gimme brainliest

Answer:

Yes

Step-by-step explanation:

When you graph y=4 it is a horizontial line going straight forever. You would mark a dot on postive four on the y-axis. For x, do the same thing mark on the negative three on the x-axis. But this one will be vertical.

REMEMBER-

Although the x-axis is horizontial when there is no Y (x,y) it will be vertical. And it is opposite for the Y.
