<span>Let's call your number N.
The sum of a number and two is doubled: 2(N+2)
Six less than 3 times the number : 3N-6
The result is : =
Let's put it all together.
The answer is d)10.
Check your answer.
The sum of a number and two is doubled: 2(10+2)=24
Six less than 3 times the number : 3(10)-6=24
Good answer.</span>
The average is 13 to get the answer you add all the numbers together then divide by how many numbers you had (ex) 12+18+13+16+6=65 then you divide by how many numbers you have (ex) 65\5=13
Answer:
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32
Step-by-step explanation:
Let Cost of one bush = x
Cost of one bonsai tree = y
From the expression: A company paid $ 391 for 15 bushes and 8 bonsai trees
We made equation:
and From the expression: They had to purchase 9 more bushes and 5 more bonsai trees for $ 241 , we made equation:
Solving both equations simultaneously we can find value of x and y
Let:
We will use elimination method to solve these equations.
Multiply eq(1) by 5 and eq(2) by 8 and subtract
So, value of x=9
Now finding value of y by putting value of x in equation 1
So, value of y=32
Cost of one bush = x = $9
Cost of one bonsai tree = y = $32
Answer:
x-1/2 is in fact a factor of 8x3-4x2+10x-5 so you are correct
Step-by-step explanation:
The equation can be simplified into (2x-1)(4x2+5) and 1/2 is one of the factors
Step-by-step explanation:
since the two angles are supplementary angles they add up to give 180°
therefore, 7x+2+3x-2=180°
or, 10x= 180°
or, x= 18°
