Answer:
1. x=27
2. x=3
Step-by-step explanation:
<h3>the first one </h3>
let's solve your equation step-by-step.
x−7=20
Step 1: Add 7 to both sides.
x−7+7=20+7
<h3>the second one </h3>
Let's solve your equation step-by-step.
3x+6=12x−21
Step 1: Subtract 12x from both sides.
3x+6−12x=12x−21−12x
−9x+6=−21
Step 2: Subtract 6 from both sides.
−9x+6−6=−21−6
−9x=−27
Step 3: Divide both sides by -9.
−9x/−9=−27/−9

Complimentary means they equal 180 so if one is 5 more then 4 times the other one is m<1= x and m<2= 4x+5°. Then solve for x. So! x+4x+5= 180. (solve to get) x=35. SO IN CONCLUSION::: <1= 35 (x) and <2= 145 (4x+5) using substitution after solving to find x.
Answer:
0.53
Step-by-step explanation:
1 - 0.47 = 0.53
Answer: 0.53
Don't know how to type the symbole infront of the 50 so I will subsitute
£50=$50
so 1:4
add it up
1+4=5
so 5 total units
$50=5 units
divide by 5
$10=1 unit
so 1:4=10:10 times 4=10:40
the answer is 10:40
