Answer:
7x-50 = -16
Step-by-step explanation:
7x + 10 = 44
x = 34/7
7(34/7) - 50 = -16
9x+7 when x+3
and
x4 when x =3
pls do step by step
Answer:
34
Step-by-step explanation:
9x+7 when x=3
Plug 3 into the equation for the variable x
So, it would be 9(3)+7
Multiply 9×3 together to get 27
Finally, add 27 and 7 together
The answer should be 34
Answer:
x=1
Step-by-step explanation: 9x+7=16
Subtract 7 from both sides.
9x=16−7
Subtract 7 from 16 to get 9.
9x=9
Divide both sides by 9.
Divide 9 by 9 to get 1.
x=1

y = 3x - 2
x - y = 4
Answer:
x=-1, y=-5
Step-by-step explanation:
y=3x-2 (1)
x-y=4 (2)
sub (1) into (2)
x-(3x-2)=4
x-3x+2=4
-2x=2
x=-1
sub x=-1 into (1)
y=3(-1)-2
=-3-2
y = -5
Therefore: x=-1, y=-5 :))
Answer:
x = -1, y = -5
Step-by-step explanation:
y = 3x - 2
x - y = 4
x - y = 4
x - (3x - 2) = 4
x - 3x + 2 = 4
-2x + 2 = 4
-2x = 2
x = -1
x - y = 4
-1 - y = 4
-y = 5
y = -5
Check:
x - y = 4
-1 - (-5) = 4
-1 + 5 = 4
4 = 4

Answer: 5√10.
Step-by-step explanation:
250 is split into its prime factors as 2 * 5 * 5 * 5 which implies √250 = √(2 * 5 * 5 * 5). Now we can simplify this further by pulling out the number which is multiplied to itself. This gives √250 = 5 * √(2 * 5) = 5√10. Therefore the square root of 250 is √250 = 5√10.

Answer:
∠ DBC = 16°
Step-by-step explanation:
∠ ABD + ∠ DBC = ∠ ABC , substitute values
2x + 15 + x - 30 = 123 , that is
3x - 15 = 123 ( add 15 to both sides )
3x = 138 ( divide both sides by 3 )
x = 46
Thus
∠ DBC = x - 30 = 46 - 30 = 16°
(1.2÷0.375−0.2)/(6 4/25 ÷15 2/5 +0.8) = (0.016÷0.12+0.7)/x
Answer:
x=1/3
read below to find out how I solved!
Step-by-step explanation:
break it down.
First do 1.2÷0.375−0.2 = 1.2.
it is now 1.2/(6 4/25 ÷15 2/5 +0.8) = (0.016÷0.12+0.7)/x
now do 6 4/25 ÷15 2/5 +0.8 = 3
it is now 1.2/3 = (0.016÷0.12+0.7)/x
now do 0.016÷0.12+0.7 and that is 5/6
now you have 1.2÷3 = 5/6 ÷ x
solve for x and you should get x = 1/3!!
