What is a fraction?
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
We have an expression:
= 3(2/5) + 1(3/10)
1):
= 3(2/5) + 1(3/10)
= 17/5 + 13/10
2):
Multiply with 2 in the term 17/5 on numerator and denominator
= 34/10 + 13/10
3):
= 34/10 + 13/10
= 47/10
Thus, the expression 3(2/5) + 1(3/10) in the improper fraction is (A) 17/5 + 13/10, with a common denominator is (C) 34/10 + 13/10, and after adding it will be (B) 47/10.

1/4a+3=31
Answers
solution of 1/4a+3=31 is a=112
\(\frac{1}{4}\)a+3=31
Transposing 3 to RHS we get
\(\frac{1}{4}\)a=31-3
\(\frac{1}{4}\)a=28
dividing1/4 with 28
a=28 x4/1
we did this because in fraction division we multiply its inverse by the dividend.
∴a=112.
To know more about fraction division:
https://brainly.com/question/1622425

=(−8x+12x)+(24+−9)
=4x+15
Hey there!
“ Simplify 4(6 - 2x) - 3(3 - 4x)”
FIRST: you have to DISTRIBUTE
4(6) + 4(–2x) + (–3)(3) + (–3)(–4x)
4(6) = 24
4(–2x) = –8x
–3(3) = –9
–3(–4) = 12x
NEW EQUATION: 24 – 8x – 9 + 12x
SECOND: COMBINE your LIKE TERMS
(24 – 9) + (–8x + 12)
24 – 9 = 15
–8x + 12 = 4x
OR........ (MAINLY this one )
(–8x + 12) + (24 - 9)
(–8x + 12) = 4x ⬅️ FRONT NUMBER
24 – 9 = 15 ⬅️ BACK NUMBER
ANSWER: 4x + 15 ☑️

He’ll need 16 trapezoids for 8 birdhouse
For 3 birdhouses, he’ll need 12 rectangles
If koda uses 4 squares, he’ll need 8 triangles
Answer:
1.) To make 8 birdhouses, Koda will need 16 trapezoids. (16)
2.) For Koda to make 3 birdhouses, he will need 12 rectangles. (3)
3.) If Koda uses 4 squares to make birdhouses, he will use 8 triangles. (8)
Step-by-step explanation:
1.) To make 8 birdhouses, Koda will need 16 trapezoids.
Explanation: The instructions showed how many trapezoids are needed to make ONE birdhouse, so you just multiply 8 by 2 which is 16.
2.) For Koda to make 3 birdhouses, he will need 12 rectangles.
Explantion: Theinstructions showed how many rectangles are needed to make ONE birdhouse, and the question ask for how many birdhouses he can make with 12 rectangles. So you need to divide 12 by 4 (12÷4) which gives you 3. 12÷4=3.
3.) If Koda uses 4 squares to make birdhouses, he will use 8 triangles.
Explantion: The instructions howed that he’ll need TWO triangles to make ONE birdhouse And the question asks for 4 squares to make birdhouse and how many triangles he’ll use. So you multiply 4x2 and got 8.
