Answer:

Each person got 18 pieces and 2 pieces were left.

Step-by-step explanation:

Mrs. Wilkins cut some orange into 20 equal pieces to be shared by 6 friends.

We need to find how many did each person get and how many pieces were left over.

We can find it as follows :

\dfrac{20}{6} = 18 pieces and 2 pieces left

It means 18 pieces got by each person and 2 pieces were left over.

Find four consecutive even integers such that if the sum of the first and third is multiplied by 3, the result is 28 less than f
WITCHER [35]

Answer:

A=-10\\B=-8\\C=-6\\D=-4

Step-by-step explanation:

We can solve the problem in this way:

- The 1st information that we have is that the four numbers are even and consecutive integer. Let's call these numbers A, B, C and D. This means that:

D=C+2\\C=B+2\\B=A+2

(since the distance between two even consecutive numbers is 2)

- The 2nd information that is given is that the sum of the first and third multiplied by 3 equals 28 less than 5 times the fourth, so:

3(A+C)=5D-28 (1)

Now we rewrite eq(1) by using:

D=C+2

and

A=C-4 (obtained by combining the 3 first equations)

So we get:

3(C-4+C)=5(C+2)-28

Solving this equation for C,

6C-12=5C+10-28\\C=-6

So the other numbers are:

A=-10\\B=-8\\C=-6\\D=-4

Please help me solve this (ASAP)

Since complementary angles add to 90°, (4x - 1) and (5x + 19), also add to 90°.

Thus, lets form an equation:

90 = 5x + 19 + 4x - 1
72 = 9x
x = 9

Thus, the measure of angle B is 64°.

Use the functions to find x
suter [353]

Answer:

x = 14

Step-by-step explanation:

f(x) = 10 -  \frac{9}{2} x \\  \\ plug \: f(x) =  - 53 \\  \\  - 53 = 10 -  \frac{9}{2} x \\  \\ \frac{9}{2} x  = 10 + 53 \\  \\ \frac{9}{2} x  = 63 \\  \\ x = 63 \times  \frac{2}{9}  \\  \\ x = 7 \times 2 \\  \\ x = 14
