Add and subtract, whichever comes first, from left to right.
Eduardwww [97]

Answer:

6. (3 + 4) - 2 + (6 + 3)

=7−2+6+3

=5+6+3

=5+9

=14

7. 5(2 + 4) + (8 – 2)

=(5)(6)+8−2

=30+8−2

=30+6

=36

8.  6+2(10 ÷ 5)-1

=6+(2)(2)−1

=6+4−1

=10−1

=9

9. 3x6+4

(3)(6)+4

=18+4

=22

10.  

20-6 ÷ 3+8  

=20-2+8

=18+8

=26

In one baseball season, Peter hit twice the difference of the number of homeruns Alice hit and 6. Altogether, they hit 18 homeru
m_a_m_a [10]
In order to solve this problem, the approach should be formulating equations such that they form a system of linear equations. Let's start by assigning variables. Let x be the number of homeruns made by Peter, and y be the number of homeruns made by Alice. Therefore,

x = 2(y - 6)

This is the equation for the relationship between Peter's and Alice's hits. The second equation would be the sum of their hits:

x + y = 18

These are the two independent equations in order to solve the two unknowns, x and y. Substituting the first equation into the second equation,

2(y - 6) + y = 18
2y - 12 + y = 18
3y = 18 + 12
3y = 30
y = 10

Using y=10 to the first equation:
x = 2(10 - 6)
x = 8

Therefore, Peter made 8 homeruns, while Alice made 10 homeruns for a total of 18.

Answer:

  a) -1 5/14

  b) -1/3

  c) -1 : 10

Step-by-step explanation:

a) 1/7 - 0,5·3 = 1/7 -3/2 = (1·2 -3·7)/(7·2) = -19/14 = -1 5/14

__

b) (3/4 -0,25)·(-2/3) = (3/4 -1/4)·(-2/3) = (2/4)(-2/3) = (1/2)(-2/3) = (-1·2)/(2·3) = -1/3

__

c) (1 5/6 -1,2) : (-6 1/3) = (11/6 -6/5) : (-19/3) = (11·5 -6·6)/(6·5) : (-190/30)

  = (19/30) : (-190/30) = -19 : 190 = -1 : 10
