Answer:

-20

Step-by-step explanation:

First, you divide both sides by -2/5, which would get you c = 8 * -5/2 (Because when you divide, you multiply by the reciprocal). 8 * -5/2 is equal to -20. The answer is -20.

Answer:

Mark needs 2 kg butter, 2 kg caster sugar, 14 eggs, and 1.5 kg flour.

Step-by-step explanation:

Alright, first you double the number of kids, as Mark wants each kid to have two cupcakes, not one. (Then add 80+80 to get 160)

Now add the adults to children: 160+152=312

now divide by 12 to see how many batches of cupcakes he needs to make.

312÷12=26 So he needs to make 26 batches

Now here are the ingredients needed to make 12 batches of cupcakes (I multiplied the amount of each ingredient by 26)

5200 g (5.2 kg) butter, 5200 g (5.2 kg) caster sugar, 104 eggs, and 6500 g (6.5 kg) flour.

now make the measurements the same as Mark's ingredients (or the other way around)

(to save time I am not showing each one, just the normal ingredients turned into kg and compared)

5 kg butter < 5.2 kg butter

5 kg caster sugar < 5.2 kg butter

90 eggs < 104 eggs

5 kg flour < 6.5 kg flour

Now do a little subtraction.....

5.2 kg-5 kg = 2 kg butter is needed....

5.2 kg - 5 kg = 2 kg caster sugar is needed....

104 - 90 = 14 eggs needed....

6.5 kg - 5 kg = 1.5 kg flour needed....

And there you go!!! Hope this helped!!! :D

The amount of ingredients that Mark still requires after getting it from the kitchen is needed.

The amount of ingredients Mark still needs is

200 g of butter

200 g of caster sugar

14 eggs

1500 g of flour

The number of cupcakes that are needed for 152 adults and 80 children is

[tex]152+2\times 80=312[/tex]

For the 12 cupcakes the ingredients are

200 g butter

200 g caster sugar

4 eggs

250 g flour

For 1 cupcake the ingredients are

[tex]\dfrac{200}{12}=\dfrac{50}{3}\ \text{g}[/tex] of butter

[tex]\dfrac{200}{12}=\dfrac{50}{3}\ \text{g}[/tex] of caster sugar

[tex]\dfrac{4}{12}=\dfrac{1}{3}[/tex] eggs

[tex]\dfrac{250}{12}=\dfrac{125}{6}\ \text{g}[/tex] of flour

For 312 cupcakes

[tex]312\times \dfrac{50}{3}=5200\ \text{g}[/tex] of caster sugar

[tex]312\times \dfrac{1}{3}=104[/tex] eggs

[tex]312\times \dfrac{125}{6}=6500\ \text{g}[/tex] of flour

The required ingredients are

[tex]5200-5000=200\ \text{g}[/tex] of butter

[tex]5200-5000=200\ \text{g}[/tex] of caster sugar

Step-by-step explanation:

Answer:

Step-by-step explanation:

We can see on the graph of g(x) that y-intercept is (0, 2)

The table doesn't have the value for x = 0 but we can observe that it is exponential function and has the formula:

We can find its y-intercept:

We can compare and see that:

So the function g(x) has a greater y-intercept. This is option A.

Note: If only the values in the table considered, then correct option is D.

The equation that can be used to find the sale price ,s, of an oil change would be =s= 0.85 (30). That is option 3.

A sale price of a product is defined as the cost of that product which shows its value in the market or economy.

The oils change at city auto = $30

The percentage of coupon that Mr Allen has = 15% of $30

That is;

= 15/100 × 30

= 450/100

=$ 4.5

= 30-4.5 = $25.5

The sale price = $25.5 which is the same as 0.85 (30) since 100-15 = 85%= 0.85

A realistic budget is hard to come by. All budgets tell you what you should include in your monthly plan, but what about unexpected expenses? Here are some ideas for making a realistic budget, and sticking to it.

Well, the dozens of apps, spreadsheets, and other methods just don’t account for real life and all the expenses we don’t think of. There are plenty of expenses we have that aren’t monthly that take up more of our money than we planned.

Step-by-step explanation:

Calculation for Jennifer's monthly gross pay

First step is to calculate The total tax percentage deductions

Using this formula

Total tax percentage deductions =State tax + City tax + Social security + Medicare

Let plug in the formula

Total tax percentage deductions = 3.5% +2.5% +6.2% +1.45%

Total tax percentage deductions = 13.65%

Now let calculate the monthly gross pay

Monthly gross pay= ($3,981.22 +87)/(1-13.65%)

Monthly gross pay= ($3,981.22 +87)/0.8635

Monthly gross pay=$4,068.22/0.8635

Monthly gross pay= $4,711.31

Answer:

B, D, E

Step-by-step explanation:

As Samuel adds money to his account we are multiplying the times he adds with 12 therefore x multiplied by 12 will give us the total he added + 60 the original number.

As of D the position does not matter because B and D are both the same.

For E if we distribute or multiply 12 into the brackets we get the same statement as that of B and D.

A does not work because he is adding 12 dollars into the account everytime and not 60 dollars, C doesn't work because we would be subtracting the amount he is adding so we would be removing the money from the bank.

The surface area the cuboid is 142 inches²

The surface area of the cuboid is given as:

= 2lw + 2lh + 2hw

where, l = length

h = height

w = width

Therefore, the surface area of the cuboid given will be:

= 2lw + 2lh + 2hw

= 2(7×3) + 2(7 × 5) + 2(3 × 5)

= 2(21) + 2(35) + 2(15)

= 42in + 70in + 30in
