6 + (2 - 3 (4) )+1 / (5) (2) - 4 = -1 /2
<u>Step-by-step explanation:</u>
6 + (2 - 3 (4) )+1 / (5) (2) - 4
Using the BODMAS rule, we can simplify the expression in the following way, like, we have to do the operation inside the brackets first, then division, multiplication, addition and then subtraction.
= 6 + (2 - 3 (4) )+1 / (5) (2) - 4 [operation inside the brackets]
= 6 + (2 - 12) )+1 / (5) (2) - 4
= 6 + (-10) )+1 / (10) - 4
= 6 + 1 -10 / (10) - 4
= 7 - 10/ 6
= -3 / 6
= -1/2
Answer:
∠B = 52°
Step-by-step explanation:
Since we know that the sum of all inner angles of the triangle equal to 180°, then we can make the following equation,
5x + 3x + 2x + 20 = 180
10x = 180 - 20
10x = 160
x = 160 / 10
x = 16
Since we know that ∠B = (2x + 20)°, we can calculate the following
∠B = (2x + 20)°
∠B = (2(16) + 20)°
∠B = (32 + 20)°
∠B = 52°

Step-by-step explanation:
Answer:
(p-1)(b+9)
Step-by-step explanation: Both terms are a(b+9), but one term has a=p and the other is -1. So add them and get the answer
Answer:
36
Step-by-step explanation:
Sean purchased a printer and laptop
He sold both for 1,500
He sold the laptop at 1,350
Therefore the cost of the printer can be calculated as follows
1500-1350
= 150
24/100×150
= 0.24×150
= 36
Henve the cost of the printer is £36
