Ten less than half of a number(x) is 6.

Likurg_2 [28]

Answer:

x = 32

Step-by-step explanation:

Given the following data;

Unknown number = x

Translating the word problem into an algebraic equation, we have;

$\frac {x}{2} - 10 = 6$

Lowest common denominator (LCD) = 2

We multiply all through by 2;

$2* \frac {x}{2} - 2*10 = 2*6$

$x - 20 = 12$

$x = 12 + 20$

x = 32

Therefore, the unknown number is 32.

1. N - 80 = 40 2. 15n = 30 3. N + 284 = 350 4. 6 + 9 = 3 x n 5. N divided by 3 = 6 +1 6. 12 - 8 = n divided by 5 7. 58 x 6 = n -

kkurt [141]

Answer:

1. $N=120$

2. $n=2$

3. $N=66$

4. $n=5$

5. $N=21$

6. $n=20$

7. $n=1398$

8. $n=5$

Step-by-step explanation:

1.

$N-80=40$

$N=40+80$

$N=120$

2.

$15n=30$

$\dfrac{15n}{15}=\dfrac{30}{15}$

$n=2$

3.

$N+284=350$

$N=350-284$

$N=66$

4.

$6+9=3\times n$

$15=3n$

$\dfrac{15}{3}=n$

$n=5$

5.

$\dfrac{N}{3}=6+1$

$\dfrac{N}{3}=7$

$N=7\times 3$

$N=21$

6.

$12-8=\dfrac{n}{5}$

$4=\dfrac{n}{5}$

$4\times 5=n$

$n=20$

7.

$58\times 6=n-(723 + 327)$

$348=n-1050$

$348+1050=n$

$1398=n$

8.

$4n+12=(7+9)\times 2$

$4n+12=16\times 2$

$4n+12=32$

$4n=32-12$

$4n=20$

$n=\dfrac{20}{4}$

$n=5$

Therefore, the solutions are 1. $N=120$

2. $n=2$

3. $N=66$

4. $n=5$

5. $N=21$

6. $n=20$

7. $n=1398$

8. $n=5$
