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:

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

X/100 = 0.05/0.37

(0.05 * 100)/0.37

X = 13.51 = 14%

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.

822672

Answer:

[tex]1\frac{3}{8} aka \frac{11}{8}[/tex]

Step-by-step explanation:

to start, think of them as decimals

1/2 = 0.5

1/8 = 0.125

4/4 = 0.75

if you add them, youll get 1.375

as a fraction this is [tex]1\frac{3}{8} aka \frac{11}{8}[/tex]

Answer:

[tex] \frac{ \frac{x + 2}{x - 1} }{ \frac{x - 3}{x - 1} } \\ = \frac{x + 2}{x - 1} \times \frac{x - 1}{x - 3} \\ = \frac{x + 2}{x - 3} \: when \: x \ne3[/tex]

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:

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]

Answer:

Step-by-step explanation:

(x,y) → (x-8, y+4)

1. (2, 6)

(2-8, 6+4)

(-6, 10)

2. (-2, 5)

(-2-8, 5+4)

(-10, 9)

3. (-3, -10)

(-3-8, -10+4)

(-11, -6)

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:

  -25

Step-by-step explanation:

Consult your memory of multiplication tables to determine the square root of 100.

  10×10 = 100

  √100 = 10

Then multiply that value by -2.5

  -2.5×10 = -25

Of course, you can use a calculator or spreadsheet to evaluate this expression, too.

Answer:

Step-by-step explanation:

When you have a rate, eg. The price is for every number of items, and the quantity in the denominator is not 1, you can calculate the price or the unit rate per unit by completing the division: the numerator divided by the denominator.

Answer:

it's the third one!

Step-by-step explanation:

ur welcome :)

[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:

arrange them in order = 1,3,3,4,4,5

then cancel them slowly from both side = 3,3,4,4

until u find a single number or two number.

for two number which is same as this do (3+4)/2 which is 7/2 = 3.5

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.
