10x + 7-x=3x + 8
Please give me answer!
Answer:
Solution: x = 1/6
Decimal form: 0.166667
Hope this helps :)
Answer:
x = 1/6
Step-by-step explanation:
10x + 7 - x : Combine like terms (In this case the x values)
9x+7 = 3x + 8 : Subtract 3x from both sides
6x + 7 = 8 : Now subtract 7 from both sides
6x = 1 : Divde both sides by 6
x = 1/6

Find the probability of rolling a die twice, first getting a 3 and then an odd number.
(This sounds simple but every answer I get isn’t the correct one)
PLEASE I DON’T UNDERSTAND
Answer: 1/3 or 0.333333333
Step-by-step explanation:
Probability of getting a 3 is 1/6.
1/6
Probability of getting an odd number is 3/6.
3/6
Multiply them.
1/6*3/6 = 4/12
Simplify.
4/12 = 1/3

Michael paints a circular
tablc that has a diameter
of 19 inches. What is the
area of the table?
Answer:
90.25π
Step-by-step explanation:
The formula for solving the area of a circle is πr².
r is the radius. We can find the radius by splitting the diameter in half: 19/2 = 9.5.
We can apply the area formula and we get π9.5² and the answer is 90.25π.

What is the solution for x in the equation
-4+5x-7=Okay 0+3x-2x
Answer:
X = 2.75 or 2 3/4 in fraction form
Step-by-step explanation:
We know that the variable X has to make both equations equal.
It is really just crossing out the options.
2.75 can fit in the X variable because if 2.75 was in both equations, the answer would be the same.
So the answer is 2.75

how do you find the value of x on this triangle?
Answer:
Solving for X in a Right Triangle
Step-by-step explanation:
Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.

The path of a race will be drawn on a coordinate grid like the one shown below. The starting point of the race will be at (−5.3, 1). The finishing point will be at (1, −5.3).
Part A: For the -5.3, 1 it would be located in Quadrant Q because even though it just goes to -4 and 4 I can extend the grid in my head and that's how I was able to figure out.

Please help me ill put the question up for a lot of point, and i will mark as brainliest!!!
Step-by-step explanation:
(2x³y^-4)^-2 = 1/(4x⁶y^‐8) = y⁸/(4x⁶)
1/(8x⁵y^-7) = y⁷/(8x⁵)
4x^-9y⁴ = 4y⁴/x⁹
so, the whole expression is then
y⁸/(4x⁶) × y⁷/(8x⁵) × 4y⁴/x⁹
4y¹⁹/(32x²⁰) = y¹⁹/(8x²⁰)
so, D is the correct answer.

A rectangle’s perimeter is 86in . Its length is 9in longer than its width. Use an equation to find the rectangle’s length and width.
Answer:
Step-by-step explanation:
Let width be x
So length would be x + 9
If perimeter is 86, then
2(l+b) = 86
2(x + x+9) = 86
4x + 18 = 86
4x = 68
X = 17
Check:
2(x + x + 9) = 86
2(17 + 17 + 9) = 86
2(43) = 86
86 = 86
Here you go

Do both of them for 50 points
Answer:
1) 5.44, 2) 3.9
Step-by-step explanation:
1) a/b + 2b - a^2 when a = 1.4 and b = 0.2
plug in the values:
1.4/0.2 + 2(0.2) - (1.4)^2 = 7 + 0.4 - 1.96 = 5.44
2) a[b-2c]^3 - d/e when a = 2, b = -0.75, c = -1, d = 0, e = -12 5/7 (rewritten to -89/7 = 12.71)
again, plug in the values:
2[-0.75-2(-1)]^3 - 0/12.71 = 2[1.25]^3 - 0 = 2[1.95] = 3.9

X and Y become positive by going up and right
Answer:
(2, 1 )
Step-by-step explanation:
A move of 2 units up in the positive y- directions means adding 2 to the y- coordinate.
A move right of 6 units in the positive x- direction means adding 6 to the x- coordinate.
(- 4, - 1 ) → (- 4 + 6, - 1 + 2 ) → (2, 1 )

Debra spends 42 minutes each day driving to work. About how many minutes does she spend driving to work each month?
Answer:
given,
time spent each day for driving to work = 42 mins time spent for driving work each month ( m ) = ?
we know ,
1 month is equal to 12 days
so,
m = 42× 12
= 504
hence, Debra spends 504 minutes driving each month.
