Can someone put a website to help me understand this?

Mathematics
1 answer:
Alenkinab [10]3 years ago

Answer:

67

Step-by-step explanation:

Since the diagonals in a rectangle are congruent, AC=BD and

7x+18=10x-3

We need to separate x -- to do that, we can first subtract 7x from both sides, resulting in

18=3x-3

Next, add 3 to both sides to get

21=3x

Divide both sides by 3 to get

x=7

Then, we just plug x into 10x-3 to get BD = 7*10-3 = 67

a_sh-v [17]
I can’t see the picture but I’m assuming it’s like this, for example: 5 10 15 20... find the next term
so you see it is going up by 5 so the next term would be 25
20+5= 25
hope this helps!

How many solutions does 4+2(5x-8)=2x+4 have
Arturiano [62]

Answer:

There is one solution: 2

Step-by-step explanation:

We need to distribute the 2 to (5x-8) which gets us the equation:

4 + 10x - 16 = 2x + 4

Add like terms on the left side

10x - 12 = 2x +4

Get the variable "x" to one side and isolate it

8x = 16

Divide both sides by 8

x = 2

2 is the only solution to this problem
