What is the solution for x in the equation
-4+5x-7=Okay 0+3x-2x
Answers
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

Answers
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.

Michael paints a circular
tablc that has a diameter
of 19 inches. What is the
area of the table?
Answers
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.

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.
Answers
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

feet below the surface of the ocean.
Answers
The distance below the surface of her previous deepest dive is 420 feet
Given the inequality expression representing the dive given as:
2/12p<−70We are to get the solution to the inequality expression;
Given;
2/12p<−70
Multiply both sides by 12:
2p < 70 * 12
2p < 840
Divide both sides by 2
2p/2 < 840/2
p < 420
Hence the distance below the surface of her previous deepest dive is 420 feet
