Answer:
Step-by-step explanation:
8x - 13 = 6x + 11
Subtract 6x from both sides
8x - 6x = 13 + 11
Add 13 to both sides
2x = 24
divide both sides by 2
x = 12
Check solution in original equation;
8(12) - 13 = 6(12) + 11
96 - 13 = 72 + 11
83 = 83
Answer:
130=8x+15 and 14 pairs
Step-by-step explanation:
Y=mx+b Since he has 130 dollars to spend, that is Y. He needs $15 to spend for an uber which would be b in an equation. He spends $8/per jean. 130(total)-15(uber)=$115 left. 115(total now)-8x. 8x14=112. 115(left)=112(14 pairs of jeans)
Answer: 10cm squared
Step-by-step explanation:
pix15 squared =47.12(2dp)
pix18 squared =56.75 (2dp)
difference =56.75-47.12=9.63
=10cm to nearest square centimetre
Answer:
c.) 476
Step-by-step explanation:
-19; -14; -9; -4; 1;............aₙ
aₙ = 5n - 24
a₁₀₀ = 5(100) - 24
a₁₀₀ = 476
Answer:
-2<x<4
Step-by-step explanation:
For 
, note that either the numerator or denominator is positive and the other must be negative for this inequality to be satisfied.
This means x+2>0 and x-4<0 or x+2<0 and x-4>0.
Lets look at the first scenario (x+2>0 and x-4<0)
x+2>0 and x-4<0
x>-2 and x<4
This means that -2<x<4.
Let’s look at the other scenario (x+2<0 and x-4>0)
x+2<0 and x-4>0
x<-2 and x>4
This means that x must be <-2 and >4 simualtaneously, which is impossible.
Therefore, this only occurs when -2<x<4.
I hope this helps! :)
