Noah spent $190 on books. Math books cost $26 and English books cost $28. If he bought a total of 7 books, then how many of each kind did he buy?

he bought three math books and four english books

Step-by-step explanation:

26x3=78 (three books)

28x4=112 (four books)

112+78=190

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
