If you take -3/10 of a number and add 1, you get 10. Write an equation to represent the situation. What is the original number?
Basile [38]
Equation - x = -3/10 + (10-1)

The original number is 9.3 because
x = -3/10 + (10-1)
x = -3/10 + 9
x = 9.3

Select the equations where x = 8 is the solution. Select all that apply (select 3).
seraphim [82]

Answer:

Step-by-step explanation:

1. x - 2 = 10

x = 10 + 2 = 12

2. 40 = 5x

40/5 = x

x = 8

3. x/2 = 8

Multiply by 2 on both sides

x = 16

4. x + 14 = 24

x = 24 - 14 = 10

5. x + 2 = 10

x = 10 - 2 = 8

6. x/8 = 1

Multiply by 8 on both sides

x = 8

No 2 5 and 6 is the correct answer

Jose takes a job that offers a monthly starting salary of $2200 and guarantees him a monthly raise of $105 during his first year
vodka [1.7K]

Answer:

$3355

Step-by-step explanation:

Since the job offers starting salary of $2200 and monthly raise of $105 during his first year of training.

∴ a = 2200 and d = 105

Since the general form of A.P is,

a, a + d, a + 2d, a + 3d, .............a_{n}

Where,  a_{n} is the last term of A.P or his monthly salary at the end of his training and n is the number of terms in a series.

So, the A.P is:

2200, 2200 + 105, 2200 + 2(105) .........a_{n}

2200, 2305, 2410 ............a_{n}

Since there is 12 month in a year therefore, n = 12.

a_{n} = a + (n - 1) d\\

.a_{n} = 2200 + ( 12 - 1) × 105

= 2200 + 11 × 105

= 2200 + 1155

= 3355

∴ .a_{n} = 3355

So the monthly salary of Jose at the end of his training is 3355$.
