Combine like terms to simplify 12x+4y-3x+2-8y²+3²

Answer:

11

Step-by-step explanation:

so we just make a system of equations:

x+y=36

say that x is the larger and y is the smaller

x-3=2y

so we can combine the equations and solve for x and y

re-arrange x-3=2y to be x=2y+3

x+y=36

x=2y+3

insert the value for x into x into x+y=36

2y+3+y=36

3y+3=36

y=11

now insert that back into x+y=36

11+x=36

x=25

Out of the two numbers x and y, 11 is the smaller number

Step-by-step explanation:

Answer:

I think the answer is A, $5.60

Step-by-step explanation:

9.80 x 9= 88.20

88.20 - 37.80 = 50.40

5.60 x 9 = 50.40

The average amount paid for the books is $12.60

Since Xuan sold 9 used books for $9.80 each, the total amount that's paid for the books will be:

= $9.80 × 9

= $88.20

Since she bought 4 new books and had $37.80 left over, the cost of the books will be

= $88.20 - $37.80

= $50.40

Since she bought 4 books, the average amount paid for the books will be:

= $50.40/4

= $12.60

Therefore, the correct option is D

Answer:

B:81

C:99

D:81

Step-by-step explanation:

In a parallelogram, opposite angles are congruent and consecutive angles (angles next to each other) are supplementary, or add to 180. Considering that there is no diagram, we can use our imagination here. So B is next to A, so <A+<B=180. <B must equal 81. I repeated this process for the rest of the angle measures.

[tex]\\ \sf\longmapsto <A=<C=99°[/tex]

sum of corresponding angles is 180°

[tex]\\ \sf\longmapsto <A+<B=180[/tex]

[tex]\\ \sf\longmapsto 99+<B=180[/tex]

[tex]\\ \sf\longmapsto <B=180-99[/tex]

[tex]\\ \sf\longmapsto <B=81[/tex]

[tex]\\ \sf\longmapsto <B=<D=81°[/tex]

Answer:

Need ( 3 ) more consecutive free throws to make to raise his free throw percentage to 75%

A percentage is a way to describe a part of a whole. To raise his free throw percentage to 75% he needs to make 3 more baskets.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given that A basketball player has made 12 of his last 20 free throws, which is equal to 60% of the free throw.

75% of the free throw will be equal to 15. Therefore, to raise his free throw percentage to 75% he needs to make 3 more baskets.

Answer:

D: ∛(¼(x + 5))

Step-by-step explanation:

The parent function is;

f(x) = ∛x

A horizontal stretch multiplying by ¼ means that our function is now;

f(x/4) = ∛(x/4)

Now shifting to the left by 5 units denotes;

f(x + 5) = ∛((x + 5)/4)

Or expressed as; ∛(¼(x + 5))

Answer:

the unit price would be 8.125

Answer:

That is the halfway mark between -6 and -7.

Make a right triangle by using half the base and using the Pythagorean theorem calculate the height.

Height = sqrt(8^2 - 5^2)

Height = sqrt(64 - 25)

Height = sqrt(39)

Height = 6.245 ( Round the answer as needed).

Answer:

6.2

Step-by-step explanation:

We can use the Pythagorean Theorem to find h.

The equation for the Pythagorean Theorem is a^2+b^2=c^2

We see that the hypotenuse of the right triangle is 8. One leg is h. The other leg is 5 , which is half the length of the base.

We have:

a^2+b^2=c^2

5^2+h^2=8^2

25+h^2=64

h^2=39

h= square root of 39

h = 6.244

Equation of a line is y = mx +c

m is the gradient, which is given as -3 so now you have:

y = -3x + c

Replace y and x with the given point and solve for c:

4 = -3(-2) + c

Simplify:

4 = 6 + c

Subtract 6 from both sides:

c = -2

The equation becomes:

y = -3x-2

Answer:

Solve all the equations.

2+n = 6

n = 4

n + 6 = 12

n = 6

4 × n = 24

n = 6

n × 3 = 2

n = 2/3

c. 273 cars

Step-by-step explanation:

First you need to find what 16% of 325 is

325x.16=52

because the number sold dropped by 16% you will subtract 52 from 325

325-52=273

you can also calculate the answer by subtracting 100% by 16%

100%-16%=84%

now you can calculate 84% of 325

325x.84=273
