Simplify. x 0 yz -3

Simplify. x 0 yz -3

Answers

Answer 1

Answer:

Answer:

y / z^3

Step-by-step explanation:

x^0 is 1 because anything to the zero power is 1

1 *y z^-3

We know a^-b = 1/a^b

y / z^3

Answer 2

Answer:

Answer:

$\small \sf \frac{y}{z {}^( 3)}$

Step-by-step explanation:

x⁰yz-³

Any non expression raised to power of 0 equals 1.

$\small \sf \: 1yz {}^( - 3)$

Express with positive exponents using $\small \sf \: a {}^( - n) = (1)/(a^n)$

1y + $\small \sf \frac{1}{ z {}^( 3)}$

$\small \sf \frac{y}{z {}^( 3) }$

Answers

2) Your answer is correct. It is B. 70.9%
4) We can round 81.25% to 80 and 21 shots to 20. 20 x 0.8 = 16.
The answer is A. about 16
5) Your answer is correct. 48% is almost half; half of $20 is $10, so the answer is D.
6) Your answer is correct, C. 15% x 100 = $15
7) The proportion 50/100 = x/70 can help solve this. The answer will be 35.
8) We simply do:
15/50 x 100 = 3/10 x 100 = 30%
9) You are correct, C. 0.3 x 60 = 18

Step-by-step explanation:

Step 1: Define

f(x) = x² + 3x - 10

f(10) is x = 10

Step 2: Evaluate

Substitute: f(10) = 10² + 3(10) - 10
Exponents: f(10) = 100 + 3(10) - 10
Multiply: f(10) = 100 + 30 - 10
Add: f(10) = 130 - 10
Subtract: f(10) = 120

Rewrite the multiplication problem using improper fractions.

1 5/6 x 2

Answers

22/6 is the result of the product of the expression.

Multiplication problem using improper fractions.

To rewrite the multiplication problem using improper fractions, we need to convert the mixed number 1 5/6 to an improper fraction.

1 5/6 = 11/6

Now, the multiplication problem can be expressed as:

1 5/6 x 2= 11/6 x 2

1 5/6 x 2 = 22/6

Therefore, the multiplication problem, using improper fractions, is 22/6

#SPJ2

you'll convert 1 5/6 by multiplying the denominator to the whole number (6) then add the numerator 6 + 5 = 11. So the answer is

11/6 x 2

I ONLY NEED HELP WITH PART BAn equation is shown below:

5x + 3(x – 5) = 6x + 2x – 15

Part A: Solve the equation and write the number of solutions. Show all the steps. (6 points)

Part B: Name one property you used to solve this equation. (4 points)

Answers

Hi there

5x+3(x-5)=6x+2x-15

Simplify both sides of the equation

5x+3(x-5)=6x+2x-15

Distribute

5x+3x-15=6x+2x-15

Combine like terms

(5x+3x)-15= (6x+2x)-15

8x-15=8x-15

Subtract 8x from both sides

8x-15-8x=8x-15-8x

-15=-15

Add 15 to both sides

-15+15=-15+15

0=0

All real numbers are solutions

To solve this equation I used " The distributive property"

I hope that's help !

Good night !

the figure below shows segments ac and ef which intersect at point b. segment af is parallel to segment ec: which of these facts is used to prove that triangle abf is similar to triangle cbe? angle fab is equal to angle ceb because corresponding angles are congruent. angle abf is congruent to angle ceb because vertically opposite angles are congruent. angle afb is congruent to angle ceb because alternate interior angles are congruent. angle afb is congruent to angle ceb because supplementary angles are congruent. i chose b, but i'm not positive it is the answer. can anyone give some clarification?
