8c + 6j = 5p Subtract 6j from both sides
8c = 5p - 6j Divide both sides by 8
c =
Answer:5 exponent of 15
Step-by-step explanation:trust
1 foot = 12 inches
12 1/2 or 12.5 inches
18 and 3/4 or 18.75 X 12= 225
The ratio is 12.5:225 or to simplify 1:18.
Answer:
Second number = -29
First number = -34
Step-by-step explanation:
Second number = x
First number = x - 5
3*(x-5) = 4x + 14
3x - 3*5 = 4x + 14
3x - 15 = 4x + 14
-15 = 4x +14 - 3x
-15 = x + 14
-14 - 15 = x
x = -29
Second number = -29
First number = -29 - 5 = -34
Answer:
y = - 19
Step-by-step explanation:
Express 210 and 55 as products of their prime factors, that is
210 = 2 × 3 × 5 × 7
55 = 5 × 11
Identify the prime factors that both numbers have in common and multiply them.
Here only 5 is common, thus
HCF = 5
Thus
5 = 210 × 5 + 55y, that is
5 = 1050 + 55y ( subtract 1050 from both sides )
- 1045 = 55y ( divide both sides by 55 )
y = - 19
