He uses 5/8 tanks of gas in one week.
In 5 he will use, 5/8 *5 = 25/8 in 5 weeks
This can be simplified too:
3.125 tanks of gas
The answer is, 25/8 tanks of gas or 3.125 tanks of gas
Answer:
that no. is 20
Step-by-step explanation:
let us take that certain no. as x
so
2/5. x +2=10
2x/5 = 10-2
2x = 8×5
x= 40/2
x= 20
Answer:(7/8 - 4/5)^2 = 9
1600
= 0.005625
Step-by-step explanation:
Subtract: 7
8
- 4
5
= 7 · 5
8 · 5
- 4 · 8
5 · 8
= 35
40
- 32
40
= 35 - 32
40
= 3
40
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - seven eighths minus four fifths = three fortieths.
Exponentiation: the result of step No. 1 ^ 2 = (3
40
) ^ 2 = 32
402
= 9
1600
In words - three fortieths squared = nine one-thousand six-hundredths.
Ok so the first step is to -1 from both sides. On the right side it cancels out and on the left side it = -16. So now your left with -16= 8x. Your still not done yet though. So now what you want to do is divide both sides by 8. On the right side it cancels out and you bring down x and on the left side it equals -2. So x=-2. So to verify it you have to plu -2 back into the equation. So -15= 8 Times -2 +1 so 8 Times -2 = -16 plus one is -15. Hoped that helped!!
Answer:
$35320.00
Step-by-step explanation:
$3.48 x 10 ^4
3.48 x 10 x 10 x 10 x 10 x 10
34800.00
5.2 x 10 ^2
5.2 x 10 x 10
520
34800 + 520 = 35320.00
