On an algebra test, I had seven times as many correct answers as
incorrect ones. There were 120 items on the test, how many did I get right?

Answer:

822,672

Step-by-step explanation:

(2045+2553-3022)\times 522

(2045+2553−3022)×522

(2045+2553-3022)522

1 Simplify  2045+2553 to 4598.

(4598-3022)times 522

(4598−3022)×522

2 Simplify  4598-3022 to1576.

1576 times 522

1576×522

3 Simplify.

Answer:

The dimensions of the Park is120m2

Answer:

The answer is 100.

Step-by-step explanation:

I started with solving 4 divided by 5. It was 0.8. I then started going thru 1 to 10 to 20 to 50 to 100. I was comparing big numbers. I then realized 100+0.8 times 100 = 180!

Answer: [tex]x=100[/tex]

If the equation is [tex]x+\frac45 x = 180[/tex] we add on the LHS: [tex]x(1+\frac45) = 180 \rightarrow x(\frac55+\frac45)= 180\\\frac95 x = 180[/tex]

At this point we divide both sides by 9 and multiply by 5:

[tex]x=\frac 59 (180) = \frac59 (2\times 9 \times 10) = 100[/tex]

ídk man u should connect it to (11, -7) since it's the only choice closest to the right answer, but If u can write the correct then write this. there's prolly an error in that quiz ídk

4. (3, -3)

(3-8, -3+4)

(-5, 1)

still not in the choices nanii but (5, -14) is the only choice left and also the closest, and even if u use calculator the correct answer is still (-5, 1). sigh, I hope this helper at least

Answer:

A

Step-by-step explanation:

A quadratic is 'involving the second and no higher power of an unknown quantity or variable.'

Therefore, we can exclude b and d easily because both have a higher power of 2. 9x^(2) is not a binomial because it only has 1 term (i think its called a term) leaving A, x^2-16x as the only answer left.

[tex](f + g)(x) = f(x) + g(x)[/tex]

[tex](f + g)(x) = |x| + 9 + ( - 6)[/tex]

[tex](f + g)(x) = |x| + 3[/tex]

If u graph this function u will realize that the range is :

[tex]y \geqslant 3[/tex]

Thus for all the values of x we have the y which is more than or equal to 3 which is telling us the First option is the correct one.

There u go.....

Answer: A

Step-by-step explanation:

Answer:

width = 15 inches

length = 30 inches

Step-by-step explanation:

Let width = w

Length =2w

Perimeter = 90 inches

2*(length + width) = 90

2*(2w +w ) = 90

2* 3w = 90

6w = 90

  w = 90/6

 w = 15 units

length = 2*15 = 30 units

Answer:

d. 14% of increase

Step-by-step explanation:

0.32 to 0.37 = increase

0.37 - 0.32 = 0.05

What percentage is 0.05 of 0.37
