Can you solve this ? 5(11*22)+15*15=220

5(11*22)+15*15=220
First things first: You use PEMDAS to do order of operations. P is parentheses so you solve the (11*22) first since its in parentheses.
5(242)+15*15=220
Now you do multiplication(M) because its next in line.
5(242)+15*15=220
1210+225=220
Now you can add(A), which is the last thing to do.
1210+225=220
1435\neq220
As you can see, the math on the left side of the equal sign does not match the number on the right side of the equal sign. That is why there is a slash through the equal sign.

BC = 4x + 2 AB = 8x + 8 and AC = 22 Find BC
Scilla [17]

Answer:

BC = 6.8

Step-by-step explanation:

The distance from A to B, then from B to C, is the same distance as from A to C.

Thus,

AB + BC = AC

AB = 8x + 8

BC = 4x + 2

AC = 22

AB + BC = AC

(8x + 8) + (4x + 2) = 22

Expanding the parenthesis:

8x + 8 + 4x + 2 = 22

8x + 4x + 8 + 2 = 22

12x + 12 = 22

Subtracting 12 from both sides:

12x = 10

Dividing both sides by 12:

x = 10/12 = 1.2

x = 1.2

We're looking for BC. As we know,

BC = 4x + 2

Let's now put in x = 1.2 into this equation:

BC = 4x + 2

BC = 4 * 1.2 + 2

Since 4 * 1.2 is 4.8:

BC = 4.8 + 2

BC = 6.8

Answer: BC = 6.8
