Answer:

1) 22\div (9+2)=2

2) 8+3\cdot 42=134

3) Option A - (12+6)\div(3+3)

4) Option D -  (75-5)\times 1+4

Step-by-step explanation:

1) Simplify 22\div (9+2)

Solution :

Add the terms in bracket,

22\div (9+2)=22\div 11

Divide,

22\div (9+2)=2

2) Evaluate 8+3\cdot 42

Solution :

Solve the dot product,

8+3\cdot 42=8+126

Add the terms,

8+3\cdot 42=134

3) Which expression has a value of 3?

Solution : Solve each expression,

A. (12+6)\div(3+3)

(12+6)\div(3+3)=18\div 6=3

B.  (12+6)\div3+3

(12+6)\div3+3=18\div 3+3=6+3=9

C. 12+6\div(3+3)

12+6\div(3+3)=12+6\div 6=12+1=13

D. 12+(6\div3+3)

12+(6\div3+3)=12+(2+3)=12+5=17

Option A is correct.

4) Which expression has a value of 74?

Solution : Solve each expression,

A. (75-5)\times(1+4)

(75-5)\times(1+4)=70\times 5=350

B. 75-5\times(1+4)

75-5\times(1+4)=75-5\times 5=75-25=50

C. 75-(5\times1+4)

75-(5\times1+4)=75-(5+4)=75-9=66

D. (75-5)\times 1+4

(75-5)\times 1+4=70\times 1+4=70+4=74

Option D is correct.

7 times what equals 1?
Arturiano [62]
For this case, the first thing we must do is define a variable.
 We have then:
 x: unknown number
 Doing the multiplication we have:
 (7) (x) = 1

 From here, we clear the value of x.
 We have then:
 x =  \frac{1}{7} 

 Therefore, we have:
 (7) ( \frac{1}{7} ) = 1

 Answer:
 
7 times 1/7 equals 1
