Answer:

45, 30, & 105

Step-by-step explanation:

<B=<D by alt. interior <s

180-150=30, so <C=30, <C=<A by alt interior <s

30+45=75

180-75=105

Answer:

sarah is correct

Step-by-step explanation:

there are not multiple ways to divide you can only use division and the equation is 15/2

Answer:

Step-by-step explanation:

Two angles are alternate and has same measurement because line l and line m are parallel so to find x:

4x - 50 = 2x + 30

4x - 2x = 30 + 50 add/subtract like terms

2x = 80 divide both sides by 2

x = 40

Answer:

The multiplicative inverse of 7 raised to - 2 is 72. Not actual 72 but 7 to the second power.

Step-by-step explanation:

9514 1404 393

Answer:

  a. $850

  b. 7 weeks

  c. f(x) = 125x +475

  d. see attached (3, 850), (7, 1350)

  e. 53 weeks

Step-by-step explanation:

After 3 weeks, $125×3 = $375 will have been added to the $475 already in the account. The balance will be ...

  $375 +475 = $850

__

The student will have to add $1350 -475 = $875 to her account to reach $1350. At a rate of $125 per week, that will take ...

  $875/($125/week) = 7 weeks

__

The initial value is $475, and the rate of change is $125 per week, so the equation can be written ...

  f(x) = 475 +125x . . . . . . . balance after x weeks

__

See the attached graph with the required points marked. (3, 850), (7, 1350)

__

It will take more than 53 weeks for the student to reach her goal. (After 52 weeks, the account will have $6975, so will be $25 short of the goal.)

Answer:

Step-by-step explanation:

Answer:

−4−6

Step-by-step explanation:

Step-by-step explanation:

100% = $1100

1% = 100%/100 = 1100/100 = 11

how many % are $600 ?

that is how often does 1% fit into $600 ?

600 / 11 = 54.545454... %

rounded that means 55%.

so, the making down percentage is then the difference

100% - 55% = 45%

Answer:

y-1= -3/4(x-1)

Step-by-step explanation:

find the slope then put it in the format: y2-y1=m(x2-x1)

y-1= -3/4(x-1)

Answer:

y = -3/4x + 7/4

Step-by-step explanation:

So we have 2 points:

(-3, 4) & (1, 1)

The formula for point-slope is:

y - y1 = m (x - x1)

First, we need to find the slope between the points

The formula for this is

(y2 - y1) /(x2 - x1)

1 - 4 / 1 - (-3) ->

-3 / 4

Our slope is -3/4 (m)

y = -3/4 (x + 3) + 4

I've done this using a simplified formula for point slope which is

y = m(x - x1) + y1

we can simplify this equation more

y = -3/4x + 7/4

is our final equation.

Beckett spent $88 in total his estimate of $80 is wrong.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Beckett went to two different stores at the mall. He purchased a $36 hat at the first store and a $52 pair of shoes at the second. Beckett estimates that he spent a little less than $80 in total.

The total spending will be calculated as,

Total = 52 + 36

Total = $88

The estimated spending is $80. Therefore, Beckett spent $88 in total his estimate of $80 is wrong.

The number 18/3 is 6 which is not an irrational number.

An irrational number, any real number that cannot be expressed as the quotient of two integers—that is, p/q, where p and q are both integers. For example, there is no number among integers and fractions that equals Square root of√2.

here, we have,

18/3

= 6

So, its not an irrational number.
