Answer:

80=X

95=X

55=X

30=X

you simply add the numbers you have together then subtract that from 180

Answer:

-88

Step-by-step explanation:

(-3 + 4) x 66 + -19 x 8 - 2

According to PEMDAS (or GEMDAS), you start with the parenthesis. So you do the equation in the parenthesis.

-3+4= 1

Now you replace it with your answer.

1 x 66 + -19 x 8 - 2

You next do multiplication.

1*66=66

66+ -19 x 8 -2

Multiplication again

-19*8=-152

66 + -152 - 2

Now there is only addition and subtraction left so you solve left to right.

66 + -152= -86

-86-2=-88

The answer is -88

Answer:

y = 4x - 9

Step-by-step explanation:

y = 4x + 2

the the slope m is 4

the new line which paraller to the first one will have a slope 4 too

M = 4

then, the new slope-intercept form which pass through (x1,y1), in this case (5,-4) is

y - y1 = M(x - x1)

y - (-4) = 4(x - 5)

y + 4 = 4x - 5

y = 4x - 5 - 4

y = 4x - 9

Answer:

Step-by-step explanation:

FYI only

Slopes of parallel lines are the same and y-intercepts are different

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

y - [tex]y_{1}[/tex] = 4( x - [tex]x_{1}[/tex] )

Substitute in y:                                                                                                  2x + (-2x + 4) = 4

Combine like terms:                                                                                         4 = 4

Here we see that 4 does indeed equal 4.

Answer:

choice 1) 2x + 40 = 180

Step-by-step explanation:

(x + 10) + (x + 30) = 180

2x+ 40 = 180

Answer:

X+30+x+10=180

combine like terms

2x+40=180

subtract 40 from both sides

2x=140

divide by 2

x=70

but for you it is 2x+40=180

Answer:

67.5 feet

Step-by-step explanation:

If 1 inch = 9 feet, and the model is 7.5 inches,

you just need to do 7.5 • 9 = 67.5 feet.

OR

7 • 9 = 63 and 1/2 (or .5) • 9 = 4.5

63 + 4.5 = 67.5

*I'm pretty sure it says 1 inch = 9 feet and I'm also basing this off the fact that your work for question 2 is showing the same ratio of 1 inch = 9 feet

Answer:

B. 2800 sq mm

Step-by-step explanation:

Given the following data;

Length = 80 mm

Width = 70 mm

Area of rectangle is given by the formula;

Area of rectangle = length * width

Substituting into the formula, we have;

Area of rectangle = 80 * 70

Area of rectangle = 5600 mm²

Since the paper (area of rectangle) was halved, we would divide by 2;

Area of each half = 5600/2

Area of each half = 2800 sq mm.

Answer:

The sequence is 2, 4, 8, 16, 32

The next answer is 2

Step-by-step explanation:

The missing terms of the required sequence are 8, 16 and 32 respectively.

In a geometric sequence, the ratio of two consecutive terms are always equal.

The general expression for the nth term is given as aₙ = a₁ × rⁿ⁻¹ .

The sum of n terms for this sequence is given as Sₙ = (rⁿ - 1)/(r - 1)

The given sequence is 1, 3, 7, 15, 31, 63...

Then, the sequence formed by subtracting the consecutive terms are given as,

3 - 1, 7 - 3, 15 - 7, 31 - 15, 63 - 31 .....

Which can be rewritten as,

2, 4, 8, 16, 32......

It is a geometric sequence as ratio of the consecutive terms are equal,

4/2 = 8/4 = 16/8

Hence, the required sequence is a geometric sequence found as 2, 4, 8, 16, 32......

Answer:

Where's the expression?

Step-by-step explanation:

Answer:

A; x< 5

Step-by-step explanation:

A simple way to remember the difference between greater than or less than is picturing the symbol as an alligator, the mouth of the alligator, the open end, eats the bigger number. The line under the greater than/ less than symbol means "or equal to". An open circle on a number line means that it's NOT "or equal to", so the answer isn't B or D. On the number line, it shows what x could equal. The arrow falls on 0, I'll use 0 as an example. Is 0 less than 5? Yes. If x could equal 0, that means that x is less than 5.

Answer:

probably C

Step-by-step explanation:

The question can be written as:

8 * 1.032^n = 140 000, this can be rearranged to

140 000/8 = 17500 = 1.032^n

now we need to find n, we could do this manually with a calculator, but an easier method is to use [tex]\log_x(y)[/tex]

example of log

2^3 = 8

log2 (8) = 3

log1.032 (17500) = 310.17

Answer:

47 mph.

Step-by-step explanation:

The unit rate would be in mph.

Divide 423 miles with 9 hours:

423/9 = 47

47 mph, or miles per hour, is your answer.

~

Given that: Train travels 432 miles in every 4 hours

To Find: Unit rate of the train

⠀⠀⠀⠀⠀⠀__________________

Solution:-

we can find the unit rate of train by divide the distance and time.

⠀⠀

[tex]:\implies\sf{speed(v)} \: = \dfrac{distance(s)}{time(t)} [/tex]

[tex]:\implies\sf Speed\; (v) = \dfrac{423}{9}[/tex]
