Answer:
Step-by-step explanation:
x+1· x+2=7
Simplify x+1· x+2: 2x+2x+1· x+2
Add similar elements: x+1· x=2x=2x+2
2x+2=7[ 2x+2=7 ]
Isolate x for 2x+2=7: x=52 2x+2=7
Subtract 2 from both sides
2x+2−2=7−2
Simplify
2x=5
Divide both sides by 2
2x2 =52 Simplify
Step-by-step explanation:
cos(x) = adjacent / hypotenuse
Answer:
$179.80
Step-by-step explanation:
799-79.80=719. That's the down payment subtracted from the total price of the refrigerator. 719/4, since there's four equal installments, gives you 179.8. Since cents go in 10s, you make it 179.80 and slap a dollar sign in front of that.
Answer:
9.5 * 10^-2 mm
Step-by-step explanation:
To find the total thickness, we proceed to add the two thickness that we have
Mathematically, this will be;
0.025 mm + 7 * 10^-2 mm
7 * 10^-2 mm = 0.07
So we have;
0.025 mm + 0.07 mm = 0.095
In scientific notation, this is 9.5 * 10^-2 mm
