4x-3(x-2)=21

4x-3x+6=21

4x-3x=21-6

x=15

is this right? let's check

4(15)-3(15-2) = 21? yes

For this case we have the following expression, we must find the value of the variable "x":

4x-3 (x-2) = 21

We apply distributive property to the terms of the parenthesis taking into account that:

- * + = -\\- * - = +\\4x-3x + 6 = 21

We add similar terms:

x + 6 = 21

We subtract 6 on both sides of the equation:

x = 21-6\\x = 15

Now, the value of x is 15

Answer:

x = 15

Ratio, Rate, and Speed
Andre45 [30]

Answer:

10:12:15

Step-by-step explanation:

a/b=5/6

b/c=4/5

thus

c/b=5/4

LCM of 4 and 6=12

5/6=10/12

5/4=15/12

b is the 12 in both

thus ratio between a:b:c is 10:12:15

i can reply in comments if more explanation is needed

A warehouse employs 22 workers on first shift and 14 workers on second shift. Eight workers are chosen at random to be interview
lara [203]
36 all together.
22 first
14 second
8 random chosen

A) all first shift:
One is pulled 22/36
Second is pulled 21/35
Third is pulled 20/34
Fourth 19/33
Fifth 18/32
Sixth 17/31
Seventh 16/30
Eighth 15/29

Multiply all those together
Probability of all first shift is 0.010567296996663
(That means it's not happening anytime soon lol)

B) one worker 14/36
Second 13/35
Third 12/34
Fourth 11/33
Fifth 10/32
Sixth 9/31
Seventh 8/30
Eighth 7/29

Multiply all those together
Probability of all second shift is 0.000099238805645
(That means it's likely to see 100x more picks of all first shift workers before you see this once.. lol)

C) 22/36
21/35
20/34
19/33
18/32
17/31

Multiply..
Probability.. 0.038306451612903


D) 14/36
13/35
12/34
11/33

X... p=0.016993464052288


Probably not correct, haven't done probability in years.

(Multiying by a unit fraction. Find the product mentally. (5.6) × 1/8=
Ipatiy [6.2K]

Step-by-step explanation:

(5.6) × 1/8

(5.6)  \cdot   \frac{1}{8}

Here the unit fraction is 1/8

multiply 5.6 times 1

so its 5.6. then divide the decimal by 8

we know that 8 times 7 is 56

so 56 divide by 8 is 7

we have decimal point 1 number to the left

so we move decimal point 2 place left

Hence 5.6 divide by 8 is 0.7

(5.6)  \cdot   \frac{1}{8}=0.7

Answer: 0.7
