On monday marco practiced the piano for 7/10 hour. On Tuesday he practiced for 1 1/4 hours each day write a question that involv

Fantom [35]

Step-by-step explanation:

Since we have given that

Number of hour Marco practiced the piano on Monday is given by

$\frac{7}{10}$

Number of hours Marco practiced the piano on Tuesday is given by

$1\frac{1}{4}=\frac{5}{4}\ hours$

1) For Adding :

Total number of hours he practiced on both Monday and Tuesday will be

$\frac{7}{10}+\frac{5}{4}\\\\=\frac{14+25}{20}\\\\=\frac{39}{20}\ hours$

2) For Subtraction,

Number of hour he practiced more on Tuesday than on Monday will be

$\frac{5}{4}-\frac{7}{10}\\\\=\frac{25-14}{20}\\\\=\frac{9}{20}\ hours$

Step-by-step explanation:

multiplying expressions.

remember every term of one expression has to be multiplied with every term of the other expression, and the results are added up (while considering their individual signs, of course).

1.

(-3×3 + 2x - 4)(3x - 2)

(-9 + 2x - 4)(3x - 2)

(-13 + 2x)(3x - 2) = -13×3x + -13×-2 + 2x×3x + 2x×-2 =

= -39x + 26 + 6x² - 4x = 6x² - 43x + 26

2.

let's do the other multiplication and compare the result with the result of 1 :

(-13 + 2x)(2x - 3) = -13×2x + -13×-3 + 2x×2x + 2x×-3 =

= -26x + 39 + 4x² - 6x = 4x² - 32x + 39

no, this product is not the same as in 1.

A box contains 146 marbles which are either red or blue. there are 28 more blue marbles than red marbles. how many blue marbles

rusak2 [61]

R + b = 146. Supposing that b=r+28,

r + (r+28) = 146, or 2r + 28 = 146.

Simplifying: 2r = 118. Then r = 59, and b = r+28 = 59+28 = 87 blue marbles
