Answer:

3n

Step-by-step explanation:

When subtracting like terms (numbers, or variable expressions that have the same variable, like these), you add the coefficients (the numbers attached to the variable) to simplify the expression.

5n - 2n

  You have 5 "n"s and you subtract 2 "n"s, leaving you with 3 "n"s

The ratio of two numbers is 4:9. When 5 is subtracted from each of them the new ratio becomes 3:8. Find the numbers.​
natta225 [31]

Answer:

FIRST NUMBER IS 20

AND

SECOND NUMBER IS 45

Step-by-step explanation:

LET THE RATIO BE X

FIRST NUMBER = 4X

SECOND NUMBER = 9X

A/Q,

=}4X - 5 / 9X - 5 = 3 / 8

CRISS CROSS,

=}8 ( 4X - 5 ) = 9X - 5 ( 3 )

=}32X - 40 = 27X - 15

=}32X - 27X = - 15 + 40

=}5X = 25

=}X = 25 / 5

=}X = 5

THEREFORE,

FIRST NUMBER

=} 4X

=} 5 × 4

=} 20

SECOND NUMBER

=} 9X

=} 5 × 9

=} 45

Use the domain {-1, 0, 1, 2, 3, 4} and plot the points on the graph that would best satisfy the equation y = 2x.
Dmitrij [34]
Domain is ur x values

y = 2x...when x = -1
y = 2(-1)
y = -2.....(-1,2) satisfies this equation

y = 2x....when x = 0
y = 2(0)
y = 0....(0,0) satisfies it

y = 2x....when x = 1
y = 2(1)
y = 2....so (1,2) satisfies it

y = 2x....when x = 2
y = 2(2)
y = 4....(2,4) satisfies it

y = 2x...when x = 3
y = 2(3)
y = 6.....(3,6) satisfies it

y = 2x...when x = 4
y = 2(4)
y = 8.....(4,8) satisfies it

A firm buys components from two suppliers: 60 percent from supplier A and the rest from supplier B. It so happens that 9 percent
Llana [10]

Answer:

0.114,0.5263

Step-by-step explanation:

Given that a firm buys  components from two suppliers:

A : 60%  Defective 9%

B:40%  Defective 15%

a) the probability that the next component the firm buys is defective

=prob purchased from A and defective + prob purchased from B and defective

= 0.60(0.09)+0.40(0.15)\\= 0.054+0.06\\=0.114

b)  the probability that the component that the firm buys is from supplier B if we know that it is defective

=Prob from B and defective/Prob defective

= \frac{0.40(0.15)}{0.114} \\=0.5263

Tamia's family traveled 5/8 of the distance to her grandfather's house on Saturday. They traveled 1/3 of the remaining distance
antoniya [11.8K]

Answer:

2/8

Step-by-step explanation:

Tamila traveled 5/8 of the distance to her grandmother house on Saturday

They traveled 1/3 of the remaining distance on Sunday

Therefore the total distance traveled to her grandmother's house on Sunday can be calculated as follows

5+1

= 6

8-6

= 2

2/8

Hence the distance travelled is 2/8
