Adding -3 to 3 makes the sum equal to 0:

3 + (-3) = 3 - 3 = 0

Answer:

c = 4n

Step-by-step explanation:

The total cost (c) is going to be of the 4 notebooks together

We don't know how many notebooks Greg got, so it's represented by n.

It doesn't matter how many notebooks Greg purchased, because each of them were $4.

So to represent the total cost of the notebooks, you would write c = 4n

Answer:

Jacob is 4 years old and his mother is 40 years old.

Step-by-step explanation:

Part 1: The linear equations are  and

Part 2: Solving the equations, we have,  and

Part 3: Jacob is 4 years old and his mother is 40 years old.

Explanation:

Part 1: Let j represent Jacob's age, and let m represent his mother's age.

It is given that, "Jacob's mother is three more than nine times as old as Jacob". Writing it as linear equation, we have,

It is also given that, "In eleven years, his mother will be five more than three times his age". Writing it as linear equation, we have,

Simplifying this, we get,

Thus, the linear equation is

The linear equations are   and

Part 2: Solving the linear equation, we get,

Substituting  in

Simplifying, we get,

Hence,

Substituting  in

Solving the equations, we have,  and

Part 3: Since, j represents jacob and m represents the jacob's mother

Thus, Jacob is 4 years old and his mother is 40 years old.

Answer:

144/91

Step-by-step explanation:

24/7 ÷ 13/6

Keep the first fraction the same, change the sign, and flip the last fraction to solve

24/7 × 6/13 = 144/91

Answer:

144/91

Step-by-step explanation:

24/7 ÷ 13/6

Keep the first fraction the same, change the '÷' sign to '× ' and reciprocal of the last fraction to solve.

Answer:

If you were going the speed limit, after 3 hrs, you would go 165 miles.

If you were going 5 miles above the speed limit you would go 180 miles.

Step-by-step explanation:

55 x 3 = 165

55 + 5 = 60

60 x 3 = 180

Answer:

165miles

180miles

Step-by-step explanation:

If going 55mph for 3 hours,

55miles/hour * 3hour = 165miles

If going 60mph (5 over the limit) for 3 hours:

60miles/hour * 3hour = 180miles

[tex]\\ \sf\longmapsto \dfrac{12}{25}\times 100[/tex]

[tex]\\ \sf\longmapsto \dfrac{12\times 100}{25}[/tex]

[tex]\\ \sf\longmapsto \dfrac{1200}{25}[/tex]

[tex]\\ \sf\longmapsto 48\℅[/tex]

The solutions to the equation [tex]6x^{2} -0.5x=0[/tex] are [tex]x=0[/tex] and [tex]x=\frac{1}{12}[/tex].

To solve the equation [tex]6x^{2} -0.5x=0[/tex] by factoring, we first need to factor out the common factor of x from the expression:

[tex]x(6x-0.5)=0[/tex]

Next, we can simplify the expression inside the parentheses by factoring out a common factor of 0.5:

[tex]x(12x-1)=0[/tex]

Now, we have two factors being multiplied together that give a product of zero. According to the zero product property, this means that either [tex]x=0[/tex] or [tex]12x-1=0[/tex]. Solving for x in the second equation, we get:

[tex]12x-1=0[/tex]

[tex]12x=1[/tex]

[tex]x=\frac{1}{12}[/tex]

Therefore, the solutions to the equation [tex]6x^{2} -0.5x=0[/tex] are [tex]x=0[/tex] and [tex]x=\frac{1}{12}[/tex].

Answer:

option 3.

Step-by-step explanation:

alright, ima explain each option.

1. "smallest odd numbers" 2 is an even number. that's out of the playing field.

2. "add up to 10" sure, they do add up to 10, but finding prime and composite numbers are all about division and multiplication.

3. this is true. 2, 3, and 5 are all prime numbers, and they have the nice divisibility rules. [ for 2, it has to be even, for 5, it has to end in 0 or 5, and 3 has to have the sum of its digits being divisible by 3. ]

4. they do multiply to 30, but this does not help break the composite numbers down.

5. we cannot make every number with just these. we can not multiply any other whole number to get 7 for per example, because it's a prime number.

Answer:

x = -46.5

x + 1 = -45.5

Step-by-step explanation:

x + x + 1 = -92

2x + 1 = -92

      -1       -1

------------------

   2x = -93

   ----     ----

    2        2

   x = -46.5

x + 1

(-46.5) + 1

-45.5

Answer:

No solution

Step-by-step explanation:

We can set up an equation where x is the integer and x+1 is the next one

x+x+1=-92

2x+1=-92

2x/2=-93/2

x=-46.5

-46.5+1=-45.5

The problem is that integers do no include decimals so there is no possible whole number. This problem would be possible if it was consecutive odd integers.

Answer:

Sarah is 60 years old

Step-by-step explanation:

64 divided by 4 is 16. Add 16 to 44 to get Sarah's age, 60

Answer: She is 60 years old

Step-by-step explanation:

Fergus has 3 1/4 cups of oats

= 13/4 cups of oats

Oatmeal bars = 2 2/3

= 8/3 cups of oatmeal used

Therefore cups of oats left = 13/4 - 8/3

= 39/12 - 32/12

= 7/12 cups of oats left

She borrowed 1 cup of oats from neighbour

7/12 + 1/1

= 7/12 + 12/12

= 19/12 cups of oats

Blueberry oats muffin = 1 3/4 cups of oats

= 7/4 cups of oats

Total she will have now = 19/12-7/4

= 19/12 - 21/12

= - 2/12

= -1/6

Which means she needs 1/6 cup of oats more

Therefore its option 4
