Answer:

x = 10.5

Step-by-step explanation:

we know that ZP = PX (its the midpoint of the rectangle)

11 = PX

ZP + PX = ZX

11+11 = ZX

22 = ZK

2x + 1 = 22

2x = 22 -1

2x = 21

x = 21/2

x = 10.5

-1.3n =7.8 need help​
xxMikexx [17]

Hey there!

-1.3n = 7.8

First, you have to DIVIDE both sides by -1.3

-1.3n / -1.3 = 7.8 / -1.3

Cancel out: -1.3 / -1.3 because it gives you the value of 1

Keep: 7.8 / -1.3 because it gives us the value of n

7.8 ÷ -1.3 = -6

Thus, n = -6 ✅

Good luck on your assignment and enjoy your day!

What is 4x+2(3x7)= if x=5
Sedbober [7]

4x + 2(3\cdot7) = ?

Now we must solve this equation if x = 5. To do so we must substitute:

4(5)+2(3\cdot7)\\

Using PEMDAS we will solve for the parenthesis first.

4(5)+2(21)

Multiply:

20+(42)

Add:

20+42=62

Final answer: 62
