Answer:
x = 6
Step-by-step explanation:
5x-3 = 2x+15
<h3>i) move 2x to the left-hand side and change its sign</h3>
5x-2x-3 = 15
<h3>ii) move -3 to the right-hand side and change its sign</h3>
5x-2x = 15+3
<h3>iii) collect like terms</h3>
3x = 15+3
<h3>iv) add the numbers</h3>
3x = 18
<h3>v) divide both sides of the equation by 3</h3>
47 the image says both triangles are similar so all you have to do is take the two angles add them than subtract it by the total of a triangle 180 and you get your answer 47
Answer:3
Step-by-step explanation:36/12=3
/ = division
32 + 0.33c = p
where c is every card more than 80 (so if you want 82 card c = 2)
and p is the total price
Answer:
12 years
Step-by-step explanation:
T + 5 = A
Therefore T =A - 5
In three years T = 3+ (A-5)
thus T = A - 2
Also in three years T = 2/3 (A+3)
Equating the two
A -2 = 2/3 (A+3)
3A - 6 = 2A + 6
3A - 2A = 6 + 6
Therefore A = 12
