Answer:

its 175

Step-by-step explanation:

7 × 7 = 49

9 × 7 = 63 but since its a triangle you have to divide it by 1/2 so that would make the area 31.5. and there is four triangles so you would multiply 31.5 × 4 = 126 then add the 49

126 + 49 = 175

9.1(6)+8.7(7)=_+60.9<br> How do I solve this?
timurjin [86]

Answer:

The answer is <u>54.6</u>.

9.1(6)+8.7(7)=<u>54.6</u>+60.9

Step-by-step explanation:

Given:

9.1(6)+8.7(7)=_+60.9

Now, to solve it:

9.1(6)+8.7(7)=_+60.9

Let the _be x.

So, we remove parenthesis first that makes it multiply with the number next to it:

9.1\times 6+8.7\times 7=x+60.9

54.6+60.9=x+60.9

Now adding on L.H.S:

115.5=x+60.9

Subtracting on both sides by 60.9 we get:

54.6=x

x=54.6

Therefore, the answer is 54.6.

What is 3x-10+2x+3x+x+20+2x+10+x-20
kodGreya [7K]

Answer:

12x

Explanation:

3x − 10 + 2x + 3x + x + 20 + 2x + 10 + x − 20

= 3x + −10 + 2x + 3x + x + 20 + 2x + 10 + x + −20

Combine Like Terms

= 3x + −10 + 2x + 3x + x + 20 + 2x + 10 + x + −20

= (3x + 2x + 3x + x + 2x + x) + (-10 + 20 + 10 + −20)

= 12x
