3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}​

Mathematics
1 answer:
Nadya [2.5K]3 years ago
3 0

Answer:

Step-by-step explanation:

Alright all we need to know is to understand our brackets

So 3+{2×(8-4+6)}-5-{9+4-[3×(1-5)]}​

3+20-5-9+4-3(1-5)

Step 2

3+20-5-9+4-3(1-5)  Simplify

18-9+4-3(1-5)

Step 3

18-9+4-3(1-5)

13-3(1-5)

13-(-12) Here is the tricky part (We aren't going to subtract because the brackets multiply the equations

So,

13+12=25

Your answer is 25

Which of these is the algebraic expression for "eight less than some number?"
kipiarov [429]
B-8 would be the answer. This is because we are saying you have 8 less than something. So no matter what something is, we are taking away 8 from it. Since our something is unknown, we use our variable 'b' in its place, and subtract 8, giving us b-8.<span />

Answer:

The proportion is \frac{35}{108} = \frac{x}{84}, and the length of the unknown side is \frac{245}{9} or 27.22 approximately rounded to the nearest hundredth.

Step-by-step explanation:

Since the triangles are similar, the proportion of corresponding sides are equal. The pairs of corresponding sides in these triangles which we'll use to solve it are LK, KE, MK, and KF. LK and KE are corresponding sides, and their proportion is \frac{35}{108}. MK and KF are corresponding sides, and their proportion is \frac{x}{84} in which x represents the missing side. The proportions are equal, so \frac{35}{108} = \frac{x}{84}. Multiply both sides by 84 to isolate the variable, and you'll get x = \frac{35*84}{108}, which is \frac{2940}{108} or \frac{245}{9}.
