Answer:

Katie is 6 years old and Thomas is 3 years old

Step-by-step explanation:

Given that we should let K and T be the current ages of two siblings, Katie and Thomas.

If Katie is currently twice the age of Thomas then,

K = 2T

and in  6 years, Katie will be 4 times Thomas's current age then

K + 6 = 4T

Solving both equations simultaneously by substituting the value of K given in the first equation into the second

2T + 6 = 4T

Collect like terms

6 = 4T - 2T

6 = 2T

Divide both sides by 2

T = 3

Recall that K = 2T

K = 2 * 3

= 6

Hence Katie is 6 years old while Thomas is 3 years old

Replace the CIRCLES by A and the SQUARES by B:

1) A + B = 14 And

2) A - B = 2

Add 1) + 2)

A+B   =14
A-B    = 2
------   ----
2A+0 = 16 then A = 16/2 = 8. If A = 8, then B = 6

So the CIRCLE = 8  and the SQUARE = 6

PLZ HELP ME PLZ I don't understand this
FinnZ [79.3K]

Answer:

97

Step-by-step explanation:

For this equation we have to plug in, so z= 6 and w=7. the question is 8z+7w

so plug in 6 for z and 7 for w. 8(6)+7(7) so 8*6 is 48 and 7*7= 49. 48+49= 97

hope this helps :)

Step-by-step explanation:

7x = (90 + 5x) \times  \frac{1}{2}

7x =   {2.5x} + 45

4.5x = 45

x = 10

Plug 10 in for x.

What is the area of the sail?
marishachu [46]
Area = 30 meters ^2

Area of a triangle is found by multiplying both sides and then dividing that answer by 2.

So 6 times 10 is 60, and 60 divided by 2 is 30.

Find the sum of 12a + 7b, −6a − 9, and 14a − 12b.
Ivan
The answer is:  [A]:  " 20a − 5b − 9 " .
______________________________________
Explanation:
_______________________________________________
  (12a <span>+ 7b) + (−6a − 9) + (14a − 12b) =
 
   12a </span><span>+ 7b  +  1(−6a − 9) + 1(14a − 12b) =
</span>    
   12a + 7b + (1*-6a) + (1*-9) + (1*14a) + (1* -12b) =
      
    12a + 7b − 6a − 9 + 14a − 12b =  ?

Combine the "like terms:

12a − 6a  + 14a = 20a ; 

7b − 12b =  - 5b ;

and then we have "-9" ;
_____________________________________________________
So, write as:   " 20a − 5b − 9 " ;  which is:  Answer choice:  [A].
