Since sum indicates addition, you want to add the two terms together.
B + (5x2)
If the answer needs to be simplified, you can do the multiplication to get:
B + 10

Answer:

x = 2

Step-by-step explanation:

$3(2x + 6) - 4x = 2(5x - 2) + 6 \\ 6x + 18 - 4x = 10x - 4 + 6 \\ 2x + 18 = 10x + 2 \\ 18 - 2 = 10x - 2x \\ 16 = 8x \\ x = \frac{16}{8} \\ \huge \: \red { \boxed{x = 2}}$

Write the expression in WORDS!<br><br> 5x + 3

Svet_ta [14]

The expression 5x+3 would be three more than five times a number! More than in this case would be addition - so if you get the same problem with subtraction you just change more to less!
Basically what it's tell you is that if x stood for 2 in this case 5*2 = 10 since it's 3 MORE than 5 times a number (x is in place of a number), you're adding 3 to 10 and that gives you 13!
I hope I simplified it a little more and you understand!
Good luck, rockstar! c: I hope this helped!

The answer is x = 7<br> Problem is I don’t how to get there

3241004551 [841]

Answer:

x=7

Step-by-step explanation:

okay so you can see that there is a isocales triangke so that means the other base angle has to be 8x

then you know that the dioganels are perpendicular to each other

so then you know that 8x+5x-1+90=180

13x-1=90

13x=91

x=7

hope that helps
