Answer:

120

Step-by-step explanation:

The rules of multiplication state, that when there are two negatives being multiplied by each other, they become positive. You will multiply -10 x -12, and since there are two negatives, they cancel out.

Now it becomes simple multiplication. Simply multiply 10 x 12, without the negatives since they have been canceled out.

-10 x (-12) = 120

Answer: He bought about 6 sodas.

Step-by-step explanation:

Given: Tota cost of tickets = $ 78

Cost of each soda = $4.25

Total cost of sodas and tickets = 102.50

Let x = Number of sodas purchased

Then

[tex]78+4.25x=102.50\\\\\Rightarrow\ 4.25x=102.50-78\\\\\Rightarrow\ 4.25x=24.5\\\\\Rightarrow\ x= \dfrac{24.5}{4.25}\\\\\Rightarrow\ x\approx6[/tex]

Hence, he bought about 6 sodas.

Step-by-step explanation:

complementary angle = 90 - angle

Answer:

a) There were 32 red pens and b) 16 blue pens.

Step-by-step explanation:

3:4

for 3:4 to be 2:1 we should add 5 in order for it to be 8:4 (2:1)

20 divided by 5 is equal to 4

8:4

8 times 4 is equal to 32

4 times 4 is equal to 16

The number of red pens that were there, in the end, is 32 pens while the number of blue pens that were there, in the end, is 16 pens

If the ratio of the number of red pens to the number of blue pens was 3: 4,

If  20 red pens are added into the box and the ratio of the number of red pens to the number of blue pens became 2:1, this means that the  5 is added to  the original ratio to have:

(5+3): 4 = 8:4

The number of red pens in the end  = [tex]8 \times \frac{20}{5}=8\times 4 = 32[/tex]

The number of red pens in the end  = [tex]4 \times \frac{20}{5}=4\times 4 = 16[/tex]

Hence the number of red pens that were there, in the end, is 32 pens while the number of blue pens that were there, in the end, is 16 pens

Answer:

You need to add Parentheses..

As you know PEMDAS states that multiplication will always go first when compared to addition unless you put Parentheses which overrules Multiplication

Step-by-step explanation:

2*6+4

you do multiplication first and get the answer 16 after addition

But if you do this: 2*(6+4) you do the addition before the multiplication because of the Parentheses and get 20. One small change can make the answer a whole lot more different

Answer:

Step-by-step explanation:

Let's solve your equation step-by-step.

22+15x−11=0

Step 1: Simplify both sides of the equation.

22+15x−11=0

22+15x+−11=0

(15x)+(22+−11)=0(Combine Like Terms)

15x+11=0

15x+11=0

Step 2: Subtract 11 from both sides.

15x+11−11=0−11

15x=−11

Step 3: Divide both sides by 15.

Answer:

x = -56/5, -11 1/5, or -11.2

Step-by-step explanation:

5/7x - 14 = -22

5x -98 = -154

5x = -154 + 98

5x = -56

x = -56/5, -11 1/5, or -11.2

Answer:

x= -11.2

Step-by-step explanation:

5/7x-14=-22

      +14 +14        Add 14 on both sides

  5/7x = -8        

(7/5)*5/7x = -8*(7/5)     Multiply by the reciprocal on both sides to leave x alone

  x= -11.2      Answer

Answer: The number of small cookies sold = 75

Step-by-step explanation:

GIven: Yesterday, the store sold 7 large cookies for every 5 small cookies.

Let 7x be the number of cookies and 5x be the number of small cookies.  (i)

They sold 30 more large cookies than small cookies.

i.e. [tex]7x-5x=30[/tex]           (Using (i))

[tex]\Rightarrow\ 2x=30\\\\\Rightarrow\ x=\dfrac{30}{2}\\\\\Rightarrow\ x=15[/tex]

Thus, the number of small cookies sold = 5 (15)=75   (Using (i))

Hence, the number of small cookies sold = 75
